How many words do you need to learn?
An analysis of English vocabulary* has found that the first 1000 words account for
84.3% of the words used in conversation, 82.3% of the words encountered in fiction,
75.6% of the words in newspapers, and 73.5% of the words in academic texts. Thesecond 1000 accounts for about another 5% (specifically, 6% of conversation, 5.1%
of fiction, 4.7% of newspapers, 4.6% of academic texts). In other words, if you learnthe top 1000 words, you would understand 84% of the words used in ordinary
conversation, and if you learned the top 2000, you would understand 90% of thewords used.
While the effort to learn this second 1000 words may seem a lot of effort for notmuch gain, the difference between understanding 84% of the words and
understanding 90% is actually quite dramatic. Learn those first 2000, and you cango out there and talk to people, and the words you dont understand will be obvious
by context a lot of the time.
You will also have enough to read novels (87.4%) not quite as good a coverage asin conversation, but good enough, especially when you consider the advantage a
book has over conversation you can take as long as you need to understandwhats being said.
I havent seen such analyses in other languages, but I imagine that the results would
be similar (perhaps even higher coverage given, since it is generally agreed thatEnglish has a particularly large vocabulary).
I.S.P. Nation says, in his widely regarded text on learning vocabulary in anotherlanguage1, that high-frequency words are so important that anything that teachers
and learners can do to make sure they are learned is worth doing.
In one sense, high-frequency words are easier to remember because you comeacross them so often. But words are inherently different in how easily learned they
are. What factors govern the learnability of individual words?
Factors that affect how easily learned a word is
8/13/2019 Approaches to learning another language
2/26
The most important factor in determining how easily words are learned is, of course,
how similar they are to the words in one's native language (or another language you
know well). Learning a language that is closely related to a language you alreadyknow is obviously a very different proposition to learning a language that is
unrelated. Thus, learning Spanish when you already know French and English andLatin (my own position) is made infinitely easier by virtue of the vast number of
words that are "cognate" (words that are the same or very similar in bothlanguages).
You do need to pay particular attention to so-called "false cognates" - words which
appear similar, but have different meanings. But in most cases that doesn't requireany special strategy; the observation that they are different is enough (provided, of
course, that you are sufficiently aware to remind yourself every time you comeacross the word - this is much easier if you are immersing yourself in a language).
Another factor is the similarity between the word and other words in the chosenlanguage that you've already learned.
Another factor is the context in which you are learning the word. You generally don'tlearn only one word at a time. So factors that will influence ease of learning will be:
the relationship between the words (it's more difficult to remember wordsthat are similar in meaning, if you try and learn them at the same time);
how many words you're learning at a time (if the words are difficult, learnfewer);
the order in which you learn them (words you learn first and last are more
easily remembered, therefore you need to give more attention to those in themiddle, to make up for it)
What's your goal?
Your strategy will also be very different depending on whether your primary goal isto understand the language (either in reading or listening) or to produce it (speaking
or writing). Learning to speak or write is of course much more difficult than simplylearning to understand (which requires recognition rather than the harder recall).
Approaches to learning vocabulary
Your approach to learning a language depends therefore on all these factors. Mostparticularly, howyou learn a language depends on whyyou want to learn the
language.
A large proportion of teach-yourself language books assume your purpose is to travel
in a country that speaks that language. Accordingly, the emphasis is on learningappropriate phrases for situations such as eating in a restaurant, buying a train
ticket, etc. Another, growing, section is aimed at business travelers, with appropriate
phrases for formal introductions, conversations in an office, etc. Both of thesecategories emphasize the conversational learning to speak and listen.
None of these, I'm afraid do anything for me. Ive tried, but they are too far from
what I want. Any time I spend on them is wasted by the little voice saying, So? Do I
8/13/2019 Approaches to learning another language
3/26
care? Why should I want to know this? My own desire is always to be able to read
the language.
I was wildly delighted when I found "Literary Chinese by the inductive method" - a1948 book that teaches Chinese by presenting the text of the simplest classic
Chinese text - the Classic of Filial Piety - and providing notes on the meaning of each
character, including notes on the derivation of those characters and their elements.This method probably would not appeal to many people, but since my primaryreason for learning Chinese is to read the classic texts, it appeals to me hugely.
A large part of the appeal is that you are learning, right from the beginning,
something "real". This is a text that people have been reading and studying for over2000 years. That alone gives the words an intrinsic fascination. And looking at each
character through its etymology gives each word a depth of meaning thatimmediately provides connections, and sometimes, emotional resonance.
For me, that is. I recognise that, for many people, this approach would leave them
cold.
The point is that, regardless of how "good" a course/book/program is, what mattersis how well it works for you. Which is why, even if you're using a "canned" system,
you still need to customize it to your own quirks and style. To do that you need tohave a wide variety of strategies to call on, and an understanding of the principles
involved.

Some word lists
A general distinction you can make is that between:
direct study, and learning from context
Direct study is more important when you're learning a non-cognate language. It's
also more important in the initial stages of learning a language. Learning fromcontext is particularly useful for cognate languages.
Of course learning a language requires both approaches, but the relative proportions
will vary.
You need both definitional and contextual information to "know" a word properly. It
is also helpful to process words at a "deeper" level - by playing with them, usingthem, thinking about them.

And of course, you need multiple exposures - a requirement for which extensive
reading is the best remedy, but in the beginning, is probably best answered by
programmed texts/courses that repeatedly present words in slightly differentcontexts (e.g., in different sentences).
Let's look at some particular techniques:
Decontextualised vocabulary
word lists- can be a useful resource. generally decontextualized; however,
sometimes they are provided in conjunction with a reading passage, thus providingcontext - this is, of course, more effective. lists of "most frequently used" words can
also be quite motivating. however, lists of difficult or less frequent words areprobably more useful. lists are also fairly tedious to learn from. their main use is
therefore as a resource- e.g., in order to make flashcards or semantic maps. (look
belowfor some word lists available on the Web)
useful to set yourself targets(daily as well as longer term)
study words in their "families" - e.g., write, written, wrote, writing, typewriter, etc
flashcards - cards with a word (or phrase) on one side and its translation on theother. You can buy ready-made flashcards, and these can certainly be helpful,
particularly if you're inexperienced at learning another language. However, it is more
effective if you make them yourself. Not only will the cards be customized to yourown use, but the activity of selecting words and writing them down help you learn
them.
A standard way of using flashcards is simply to go through a set number each day,separating out those you have trouble with, so you can review them more often.
Keep these ones handy so that you can go through them at odd moments during theday when you're waiting for something.
Use the flashcards as a handy way to group words in different ways. Deal out the
cards and move them around, looking for connections.
If you have word-family flashcards (recommended) - e.g., cards with various related
forms of a word - you can make different sentences with your cards. You could alsoplay cards with them, if you have others to play with. You could play a version of
rummy, for example, where the sets are infinitive, present tense, future tense, pastperfect. Use your imagination!
A bingo game with flashcards is another fun way to practice. Construct bingo cards(large cards divided into a certain number of spaces the same size as yourflashcards) with the native language words on it. While this is better played with
others, you can at a pinch play with yourself, simply picking out a flashcard from thepile and seeing how quickly you can match it with its counterpart.
Learning words in isolation will not help you much in dealing with words in context.You do need to practice reading/writing/speaking/listening sentences. But flashcards
are a useful means of memorizing vocabulary.

drill- good for getting in the needed repetition; most useful when they involve
multiple media; when they group words according to context (words that "belong"
together, for one reason or another), rather than, as is often the case, according tofrequency; when they provide full and immediate feedback
bilingual-dichotic method- This is a somewhat specialized technique. Dichotic
listening refers to a technique used in the psychology laboratory, whereby a personwearing headphones hears different messages in the left and right ear. Thetechnique has been used with some success in teaching foreign language words - the
foreign word is heard in the right ear while simultaneously the native translation is
heard in the left ear (most people process speech better in the right ear). Thestudent is instructed to attend to the foreign language word. The student also has a
list of the words to read while listening.
You can read more about this research at
http://agoralang.com/agora/agoranews/aarons.html
Reading
graded reading- is, after all, the means by which most of us acquired the bulk of
our native language vocabulary; the main problem with this approach, when applied
to another language, is that you need to understand around 95% of the words in atext in order to infer the meaning of the rest. this makes it harder to simply grab
books aimed at the native speaker - you need graded readers, specifically created forstudents of the language. another useful resource to build up your vocabulary are
bilingual readers.
the great benefit of reading is the repeated experiences of the same words in slightly
different contexts; the down side is that it is a time consuming method of learning.also, infrequent words will, of course, appear infrequently - these words really needto be given special attention.
dictionary use- using a bilingual dictionary is of course helpful, and oftennecessary; however, it is better if looking things up in the dictionary is NOT your first
strategy - better to try and guess the meaning first. effective students tend to use a
dictionary flexibly and thoughtfully; they are also better at judging when guesses arelikely to be accurate, and which words in a sentence are most important for
understanding the meaning.
a useful strategy to prevent you getting too bogged down, is to mark the words
you're in doubt about, on your first reading, and then look them up at the end of thepassage.
the Web is a great resource for language students - find a newspaperin your
chosen language and practice with it regularly; find a radio stationthat broadcastsin your chosen language
I find DVDswonderful - look for ones that offer your chosen language. You canlisten in your native language and have subtitles in your chosen language; listen to
http://agoralang.com/agora/agoranews/aarons.htmlhttp://agoralang.com/agora/agoranews/aarons.html8/13/2019 Approaches to learning another language
7/26
your chosen language with native language subtitles; or, have both the soundtrack
and the subtitles in your chosen language.
Retelling
try to retellpassages of text in your own words
recountingwhat you have learned to someone else is an excellent way to reinforce
learning (trying to teach them is better still!)
remember to speak aloudwords as you read/think them
talk to yourself- tell yourself what you're doing as you do it; make up sentences
about what you can see when you're walking, or waiting for something
try and think of different waysof saying the same thing
Organization
have a notebookto record new words and grammar points; don't simply list the
words as you come across them, but organise them into categories- categories
that are personally meaningful. for ready reference, start the notebook with a list ofwords you find or think you'll find particularly difficult. (note: useful groups include
generic categories, e.g., animals, fruit; functions, e.g., greetings, prepositions;situations, e.g., Post Office, airport, shop)
make labelsfor items round the home and stick them up - and don't limit yourself
to single words, create sentences. remember to read them aloud at appropriatemoments.
in the bathroom and toilet, put up listsof declensions/conjugations or even
passages of text or dialog.
Association
even unrelated languages throw up words that share similarities- look out forthese. Be creative.
physically act out words and sentences - use mimeand gestures(for someresearch on how gestures help you remember see People remember speech better
when it is accompanied by gestures ; Gesturing reduces cognitive load)
associate words with pictures

mnemonics
Review
periodic review- vital!
to make sure words are "fixed", you need to overlearnthem - don't tick them off
too soon!
daily practiceis essential, but try not to get into a rut. Routine is useful forestablishing a habit, but ring the changes with your activities, both to keep your
interest up, and because it is a more effective means of learning.
Remember:
Experiment with different strategies till you find what works for you.
Aim to have a variety of strategies to choose from.

Mnemonics for learning languagesKeyword mnemonic
Linkword
List-learning strategies
Keyword mnemonicThe one mnemonic strategy that has been investigated quite extensively by
researchers is the keyword mnemonic. This has been used successfully in a variety oflearning areas, but its chief use has been in the area of learning vocabulary.
The keyword mnemonic is certainly an effective technique, particularly for learning to
read in another language, as opposed to writing ortalking (where you have toactively remember the words you want, rather than simply recognize them when you
see them). But I wouldn't advocate using the keyword mnemonic on 1000 words, oreven most of them. I would keep it for the hard words. (See the pdf document on
mnemonics to find out what the keyword mnemonic is and to find out more aboutthe usefulness of the keyword mnemonic for learning vocabulary.)
Linkword
This is essentially the keyword technique, but simplified by fact that someone elsehas done all the hard work. Dr Michael Gruneberg, a British academic who has done
a lot of work in the area of practical mnemonics (a rare concern among academicresearchers) formalised the Linkword technique for learning foreign languages, and
has produced Linkword books for learning French, German, Spanish, and Italian.
The books aim to quickly teach you a few hundred words of your chosen language(my own count of words taught in the German book was 355), by giving you a
linking image to use. Thus, for Raupe (German for caterpillar), you are told toimagine a caterpillar with a rope attached to its middle.
As you would expect (Dr Gruneberg does know his stuff), the books are designed
with an eye to fundamental memory principles. Words are grouped according tocategory; only ten words are given at a time; words are reviewed, etc. Simple
grammar points are also included. It's well organised, and I do think it's an excellent
way for a beginner to get a quick introduction to the language.
Apart from my general criticisms and warnings about the keyword technique (for
which, see my article on the usefulness of the keyword mnemonic for learning
vocabulary), my principle caveat is the difficulty in forming the visual images. Forexample, for Hummer (German for lobster), we are told to imagine a lobster with a
sense of humor. Similarly, for Motte (German for moth), we are told to imagine thatour personal motto is "I like moths". Personally, I don't find it particularly easy to
visualise these "images". Now, I mean no criticism of Dr Gruneberg, the difficulty isexperienced by anyone trying to find images to express verbal connections; some
words just don't lend themselves to being images. But of course, verbal mnemonicsare just as memorable as visual mnemonics, and infinitely more flexible. I assume,
8/13/2019 Approaches to learning another language
10/26
although he doesn't say it, that Dr Gruneberg means by "image" something more
movie-like, with a sound track.
There are also Linkword coursesavailable, in a wider variety of languages, and forsome languages, at more advanced levels (this link is for a British site; here's a U.S.
site). I have no personal experience of these, but here's a reviewby a teacher.
List-learning mnemonicsThe various list-learning mnemonics - the method of loci, the pegword method, the
link method, the story method - can all be adapted to help you learn lists of words.In general, learning lists is not a particularly useful technique for learning a
language, however, there are some circumstances in which it can be helpful. (To find
out about these mnemonic techniques, see the pdf document on mnemonics).
If you do need to remember a list, my own recommendation is the story mnemonic,
unless you are already expert at one of the other techniques. The advantage of the
story mnemonic is that it is very simple to master.
Here's an example of its use. I'm brushing up my Latin, and like to run through the
various conjugations and declensions in my head before going to sleep (it's
wonderfully soothing!). To ensure I cover them all, I've devised the followingmnemonics:
I loveto advisethose who rulethat sums are fooey. [1st conjugation: amo, Ilove; 2nd conjugation: moneo, I advise; 3rd conjugation: rego, I rule; irregular verb
to be: sum, I am; fui, I have been]
At the tablethe daughterawaits the master; the sonawaits the godin the field
where the boys go to war. The kingtells the legionhis nameis a burden. The
citizenlies on his couchin the city. [1st to 3rd declensions, with variants]
Basic principles
When considering what will be the most effective strategies for you, don't forget the
basic principles of memory:
(1) Repetition repetition repetition
The trick is to find a way of repeating that is interesting to you. This is partlygoverned by level of difficulty (too easy is boring; too difficult is discouraging). The
point is to find an activity (more than one, in fact), which enable you to hold on toyour motivation through sufficient repetitions to drive them into your head. Bear in
mind, too, the importance of:
(2) Changing context

11/26
Simple repetition (cat - el gato; cat - el gato; cat - el gato ...) is not only boring, but
also the least effective way of experiencing the needed repetition. Not only do you
want to see/hear words presented in a variety of different sentences; you also wantto experience them in different ways - listening, reading, speaking, writing.
(3) Space your practice (see the pdf document on learning a skill)
(4) Seek the link
The basis for the keyword mnemonic, and the reason some words are "easy" and
others not. Looking for the similarities between words, and being inventive whennecessary, is crucial to easing the learning burden, and reducing the number of
repetitions you need to fix the word in your memory. It can be as simple as
observing that "gato" is very like "cat", or that "el borrego" means "sheep" becausesheep are boring.
Effect of working memory capacity on new languagelearning
Summary
Vocabulary acquisition in children is significantly affected by the child's ability torepeat back words.
This limitation becomes less as the individual gains a large vocabulary, and thus
develops a greater ability to make semantic (meaningful) associations.
When learning a new language, your ability to repeat back unfamiliar words is only afactor where you are unable to form a meaningful association to a familiar word.
In such cases, the keyword mnemonic can be especially useful to those with limitedability to repeat back words.
Research with children has demonstrated that the ability to learn new words isgreatly affected by working memory span - specifically, by how much information
they can hold in that part of working memorycalled "phonological short-term
memory". The constraining effect of working memory capacity on the ability to learn
new words appears to continue into adolescence. (see Reading skills in youngchildren)
But, as you grow in experience, building a vocabulary, this constraint becomes lessimportant. Because working memory capacity is measured in "chunks" - and the
amount of information contained in a chunk is extremely malleable. To a largeextent, developing chunking strategies is what memory improvement is all about.
8/13/2019 Approaches to learning another language
12/26
In terms of learning another language, there are essentially four possible classes of
word:
words that are already familiar because they are the same in your nativelanguage (or another known language)
words that are already familiar because they involve words that you already
know in that language (e.g., learning a related verb form, or learning a wordmade up of two words you already know, such as sweat-shirt)
words that resemble a known word with similar or related meaning (e.g.,
Russian garlomeans throat, and the word garloresembles the word gargle) words that have no ready association to known words
It appears that in these first three cases, the size of your phonological short-term
memory is of no significant relevance. It is only in the last case - where the wordcannot utilize any meaningful associations - that your phonological short-term
memory capacity becomes important.
Fairly obviously, as your knowledge of language (your own and others) grows, the
more meaningful associations you will be able to make, and the fewer new words willfall into this last, difficult, category.
This suggests, of course, the usefulness of a mnemonic strategy (specifically, thekeyword strategy) in the last, difficult case.
The importance of phonological short-term memory is also greater for productive
learning (learning to produce a language, i.e., speak or write it) than in receptivelearning (learning to read or understand a language). For productive learning, the
pronounceability of the new words is very important. The more easily pronounced,the more easily learnt.

Are children really so much better at learning a secondlanguage?
Most people believe that an adult learner can't hope to replicate the fluency ofsomeone who learned another language in childhood. And certainly there is research
to support this (see Second language best taught in childhood; Study finds there's acritical time for learning all languages, including sign language)
However, people tend to confuse these findings - that the age of acquisition affects
your representation of grammar- with the idea that children can learn words vastlyquicker than adults. This is not true. Adults have a number of advantages over
children:
they usually have more and practised strategies available to them,
they have a wider vocabulary in their native language (which makes it easier
to find similarities between languages),
they have (for a while) a greater working memory capacity,
they are more likely to have experience of other languages, and of languagelearning.
For all these reasons, adults can usually learn more words faster than children.
Part of the reason for the belief is that children seem to learn their native language
"by magic". While there is certainly something magical about the way they pick upgrammar, their learning of new words doesn't come under the same category. In
fact, children are quite slow at learning new words, learning on average:
12 - 16 months: 0.3 words/day
16 - 23 months: 0.8 words/day
23 - 30 months: 1.6 words/day
30 mths - 6 yrs: 3.6 words/day
6 yrs - 8 yrs: 6.6 words/day
8 yrs - 10 yrs: 12.1 words/day
(from Paul Bloom's (2000) "How Children Learn the Meanings of Words")
Original language can be completely forgottenThe following research is also interesting, since it exposes another cherished myth. A
study1of adults who were born in Korea but adopted by French families in childhood,found not only that they had no conscious memory of Korean, but that imaging
showed no difference in brain activation when they heard Korean compared to anyother unknown foreign language (activation patterns were different when they heard
French).

I don't, however, know the age of the children when they were adopted. It would
also be interesting to know whether such children would learn their original language
with greater facility - this would imply that present imaging techniques areinsufficiently subtle to pick up some differences.

Music and language
Summary
Some of the attributes of music are particularly memorable, and can be used toassist learning.
Music and language are both important in helping humans form large social groups,
and one can argue that they co-evolved on the back of this function*.
There is growing evidence that the same brain structures are involved in music andlanguage processing.
A rare disorder suggests a genetic link between social skills, language skills, andmusical skills.
These connections between music and language processing support recent evidencethat music training can improve children's language skills.
The role of melody in helping recall
The most obvious connection between language and music is that music can be used
to help us remember words. It has been convincingly shown that words are betterrecalled when they are learned as a song rather than speech - in particular
conditions.
Melody is what is important. Rhythm is obviously part of that. We are all aware ofthe power of rhythm in helping make something memorable. But melody, it seems,has quite a lot of attributes, apart from rhythm, that we can use as cues to help our
recall. And what seems to be crucial is the simplicity and predictability of the
melody.
But the connection between language and music is much more profound than this.

The evolution of language
One of my favorite books is Robin Dunbar's Grooming, gossip and the evolution of
language. In it he moves on from the fact that monkeys and apes are intenselysocial and that grooming each other is a major social bonding mechanism, to the
theory that in humans language (particularly the sort of social language we call
gossip) has taken the place of grooming. The size of human social groups, heargues cogently, was able to increase (to our species' benefit) because of theadvantages language has over grooming. For example, it's hard to groom more than
one at a time, but you can talk to several at once.
Language, music, and emotion
I mention this now because he also suggests that both music and language helpedhumans knit together in social groups, and maybe music was first. We are all familiar
with the extraordinary power of music to not only evoke emotion, but also to bind usinto a group. Think of your feelings at times of group singing - the singing of the
national anthem, singing 'Auld Lang Syne' at New Year's Eve, singing in church,
campfire singing, carol singing ... fill in your own experience.
Dunbar also observes that, while skilled oratory has its place of course, language is
fairly inadequate at the emotional level - something we all have occasion to noticewhen we wish to offer comfort and support to those in emotional pain. At times like
these, we tend to fall back on the tried and true methods of our forebears - touch.
So, while language is unrivalled in its ability to convey "the facts", there is a point atwhich it fails. At this point, other facilities need to step in. At an individual level, we
have touch, and "body language". At the social level, we have music.
Language and music then, may well have developed together, not entirely
independently. More evidence for this comes from recent neurological studies.
The neural substrates of language and music
Language is a very important and complex function in humans, and unsurprisingly it
involves a number of brain regions. The most famous is Broca's area. Recentresearch into neurological aspects of music have held some surprises. Imaging
studies have revealed that, while the same area (the planum temporale) was active
in all subjects listening to music, in non-musicians it was the right planum temporalethat was most active, while in musicians the left side dominated. The left planum
temporale is thought to control language processing. It has been suggested thatmusicians process music as a language. This left-brain activity was most pronounced
in people who had started musical training at an early age (August 2001 newsreport).
Moreover, several studies have now demonstrated that there are significant
differences in the distribution of gray matter in the brain between professionalmusicians trained at an early age and non-musicians. In particular, musicians have
an increased volume of gray matter in Broca's area. The extent of this increaseappears to depend on the number of years devoted to musical training. There also
appears to be a very significant increase in the amount of gray matter in the part of
http://www.amazon.com/exec/obidos/ASIN/0674363361/thememorykey-20http://www.amazon.com/exec/obidos/ASIN/0674363361/thememorykey-20http://www.amazon.com/exec/obidos/ASIN/0674363361/thememorykey-20http://www.amazon.com/exec/obidos/ASIN/0674363361/thememorykey-208/13/2019 Approaches to learning another language

the auditory cortex called the Heschl's gyrus (also involved in the categorical
perception of speech sounds). (see news reports)
An imaging study1investigating the neural correlates of music processing found that" unexpected musical events" activated the areas of Broca and Wernicke, the
superior temporal sulcus, Heschl's gyrus, both planum polare and planum temporale,
as well as the anterior superior insular cortices. The important thing about this isthat, while some of those regions were already known to be involved in musicprocessing, the cortical network comprising allthese structures has up to now been
thought to be domain-specific for language processing.
People are sensitive to acoustic cues used to distinguish both differentmusicians and different speakers
Another study2has found that people remember music in the same way that they
remember speech. Both musicians and non-musicians were found to be equallyaccurate in distinguishing changes in musical sequences, when those changes were
in the length and loudness of certain tones. This discrimination appeared to also be
within the capabilities of ten-month-old babies, arguing that the facility is built intous, and does not require training.
These acoustic characteristics are what make two musicians sound different whenthey are playing the same music, and make two speakers sound different when they
are saying the same sentence.
So, if this facility is innate, what do our genes tell us?
Williams syndrome
Williams syndrome is a rare genetic disorder. Those with this syndrome have
characteristic facial and physical features, certain cardiovascular problems and mildto moderate mental retardation.
They are also markedly social, and have greater language capabilities than youwould expect from their general cognitive ability. They score significantly higher on
tests measuring behavior in social situations, including their ability to remembernames and faces, eagerness to please others, empathy with others' emotions and
tendency to approach strangers.
This connection, between sociability, language skills, and memory for names andfaces, is what makes Williams syndrome interesting in this context. And of course,
the final characteristic: an extraordinary connection with music(see http://www.the-scientist.com/yr2001/nov/research_011126.html(free

Mozart effect
A Canadian studyis now underway to look at whether musical training gives childrenan edge over non-musical counterparts in verbal and writing skills (as well as
perhaps giving the elderly an edge in preserving cognitive function for as long aspossible). In view of thse factors discussed here, the idea that music training

The Mozart Effect
The "Mozart Effect" refers to two phenomena.
The effect of merely listening to Mozart is small, unreliable, relates only to spatial
reasoning, and probably simply reflects the effect of arousal.
The effect of providing musical training to children is probably real, but again, ismore limited than advertised.

The more hyped and less plausible passive Mozart EffectThe so-called "Mozart effect" refers to two quite different phenomena. The one that
has received the most media play concerns the almost magical (and mythical) effect
of Mozart's music on intelligence. It is the result of a misrepresentation of theresearch results. Rauscher, Shaw, and Ky's 1993 study found that 10 minutes ofexposure to Mozart's Sonata for Two Pianos in D Major K. 448temporarily enhanced
performance on three spatial reasoning tasks.
The source of the misunderstanding lay in the fact that spatial reasoning is acomponent of IQ tests, and the researchers reported an increase of some 8 or 9
points in students' IQ scores after listening to the music. The effect lasted some tento fifteen minutes.
Even in this limited sense, the effect has not been consistently replicated - indeed, it
would be fair to say it has more usually failed to be replicated. Moreover, a meta-
analysis of studies that have investigated this effect has found that any cognitiveimprovement "is small and does not reflect any change in IQ or reasoning ability ingeneral, but instead derives entirely from performance on one specific type of
cognitive task and has a simple neuropsychological explanation"1.
There does seem to be a case that particular types of music can have an effect onbrainwaves - there has been some interesting work done on its possible therapeutic
role in reducing epileptic seizures - but the main effect of music seems to be throughits effect on arousal.
Most of the research done into the Mozart Effect has continued the example of theoriginal researchers by comparing the effect of listening to Mozart's music with
listening to silence or to a relaxation tape. Obviously enough, these varioussituations would be expected to differentially affect mood and level of arousal (whichare known to have a, small and unreliable, effect on cognition). There is evidence
that when this effect is controlled for, the Mozart effect (which we may note is alsosmall and unreliable) disappears.
The more plausible active Mozart effectThere is however another Mozart effect that promises to be more useful. This is thepossibility that formal training in music yields nonmusical benefits. Once again, the
media are keen to hypothesize that this effect is on IQ (what isthe media'sobsession with IQ?). There does however seem to be growing evidence that musical
training benefits other faculties - specifically, verbal memory. (see the July news
report)

Gesturing
People remember speech better when it is accompanied by gestures
A recent study had participants watch someone narrating three cartoons. Sometimesthe narrator used hand gestures and at other times they did not. The participants
were then asked to recall the story. The study found that when the narrator usedgestures as well as speech the participants were more likely to accurately remember
what actually happened in the story rather than change it in some way.
The research was presented to the British Psychological SocietyAnnual Conference inBournemouth on Thursday 13 March.
Gesturing reduces cognitive load
Why is it that people cannot keep their hands still when they talk? One reason maybe that gesturing actually lightens cognitive load while a person is thinking of what
to say. Adults and children were asked to remember a list of letters or words while

Language learning in childhood
Second language best taught in childhood
Sadly, it does appear that the easiest time to learn a second language is, indeed, inchildhood. An imaging study has found that when grammatical judgment in the
second language was compared to grammatical judgment in first language (as
evidenced by performance on sentences with grammatical mistakes), there was nodifference in brain activation in those who learned the second language as children.
However, people who acquired the second language late and with differentproficiency levels displayed significantly more activity in the Broca's region during
second language grammatical processing. "This finding suggests that at the level ofbrain activity, the parallel learning of the two languages since birth or the early
acquisition of a second language are crucial in the setting of the neural substrate forgrammar."

Critical period for learning a first language
It is generally believed that there is a critical period for learning a first language, andthat children not exposed to language during this period will never fully acquire
language. It is also thought that this might apply as well to second language learning
that those who learn another language after puberty can never become as fluentas those who learn it before puberty. A recent study suggests that this may also be
true for non-verbal languages. Using functional magnetic resonance imaging (fMRI),it was found that patterns of brain activity in bilingual people who learned American
Sign Language (ASL) before puberty differed from those who learned it afterpuberty.

the relationship.Applied Cognitive Psychology, 13, 65-77.
Finding: The ability of a child to repeat back unfamiliar words is constrainedby the capacity of their working memory rather than their ability to
articulate the words. The constraining effect of working memory capacity onthe ability to learn new words continues into adolescence.
The effect of phonological short-term (working) memory and vocabulary knowledgewas explored in two experiments (see below for a discussion of this effect). In the
first experiment, four-year-olds were given various working memory tests (nonword
repetition; digit span; nonword recognition). The correlation between workingmemory capacity and vocabulary knowledge was as strong for the serial recognition
task as for the recall-based tests, supporting the view that it is working memorycapacity rather than speech output skills which constrain word learning. In the next
experiment, the same association between memory capacity and vocabularyknowledge was found to be strong in teenagers, indicating that these working
memory constraints remain significant throughout childhood.
Gathercole, S.E., Willis, C.S., Baddeley, A.D. & Emslie, H. 1994. The Children's test
of Nonword Repetition: a test of phonological working memory. Memory, 2, 103-27.
Finding: The ability of a child to repeat back unfamiliar words is constrainedby the capacity of their working memory, and affects their ability to learn
new words, as well as the ability to comprehend what they hear or read.
The Children's test of Nonword Repetition (CNRep) involves the child hearing a singlenovel word-like item, such as "barrazon", and being required to immediately repeat
it back. This occurs for 40 such items. Performance on this test is highly correlatedwith conventional tests of phonological working memory, and it appears that the
ability to repeat back unfamiliar words is affected by the capacity of this aspect (thephonological loop) of working memory.
The test is particularly appropriate for young children, as it is a familiar task (young
children are of course constantly coming up against unfamiliar words and often try to
repeat them) and they usually readily understand what to do.A number of studies have consistently found poor CNRep scores in children who arepoor readers, and very low scores in children who are reading-impaired (such as
dyslexics). Adults with various language processing disorders also perform poorly onthis test.
Working memory capacity (which varies among individuals) affects many aspects of
comprehension and recall. Among normal adults, working memory constraintsusually only affect comprehension of particularly long and grammatically complex
sentences. Among children, the ability to repeat back unfamiliar words affects bothlanguage comprehension and the learning of new words.
Crain-Thoreson, C. 1996. Phonemic Processes in Children's Listening and Reading
Comprehension.Applied Cognitive Psychology, 10, 383-401.
Finding: Rhyme appears to be more confusing than other phonemicsimilarities and can affect how clearly the child remembers what a heard
story was about. However recall of verbatim details does not appear to beaffected, and the susceptibility of a child to phonemic confusion doesn't
appear to affect their reading skill.Kindergarten and second-grade children were told phonemically confusing stories
and second-graders were given phonemically confusing stories to read. It was foundthat rhymes were more consistently confusing than alliteratives in both the listening
and reading tasks at both grade levels. This suggests not only that rhyme is
8/13/2019 Approaches to learning another language
23/26
inherently more confusing than alliteration, but that similar information is being
activated when children listen and when they read silently.
Both kindergarten and second-grade children showed phonemic confusion in theirremembering of the gist of the stories that they heard, but prereaders were less
likely than readers to show signs of phonemic confusion in their verbatim recall.However, children's sensitivity to phonemic information did not appear to affect their
reading skill.
Music and language
How professional musicians process music
A magnetic-resonance study has found that professional musicians use their leftbrain more than other people when listening to music. In particular, while the
planum temporale was activated in all subjects listening to music (a Bach piece), innon-musicians it was the right planum temporale that was most active, while in
musicians the left side dominated. The left planum temporale is thought to control
language processing. It may be that musicians process music as a language. Thisleft-hand brain activity was most pronounced in people who had started musicaltraining at an early age, as well as in those with absolute or 'perfect' pitch
(suggesting that musical traits such as absolute pitch are the result of childhood
training rather than genetic predisposition).Ohnishi, T., Matsuda, H., Asada, T., Aruga, M., Hirakata, M., Nishikawa, M., Katoh,

Significant brain differences between professional musicians trained at an
early age and non-musicians
Research has revealed significant differences in the gray matter distribution betweenprofessional musicians trained at an early age and non-musicians. It is most likely
that this is due to intensive musical training at an early age, although it is alsopossible that the musicians were born with these differences, which led them to
pursue musical training.Schlaug, G. & Christian, G. Paper presented May 7 at the American Academy of
Neurology's 53rd Annual Meeting in Philadelphia, PA.

Another link between music and language
New research augments earlier findings concerning the amount and distribution ofgray matter in the brains of professional musicians. It now appears that musicians
also have an increased volume of grey matter in the Broca's area, an area of thebrain involved in the production of language. A critical factor appears to be the
number of years devoted to musical training - at least for musicians under the age of50. The research supports recent suggestions that musicians process music like an
additional language.

More grey matter in the auditory cortex of musicians' brains
A German study has found that a region of the auditory cortex was more active inprofessional musicians listening to tones of varying frequencies compared to amateur
musicians and considerably more active than that of non-musicians. More
surprisingly, there was a very significant difference in the amount of "grey matter" inthe part of the auditory cortex called the Heschl's gyrus. The structure contained 536
to 983 cubic millimetres of grey matter in professionals, 189 to 798 cubic millimetresin amateurs, and 172 to 450 cubic millimetres in non-musicians.

Mozart effect
Music instruction aids verbal memory
Research has shown that the region of the brain involved in verbal memory is largerin adult musicians than in those who are not musicians. Now a new study finds that
children with music training had significantly better verbal memory than thosewithout such training. The study involved 90 boys between six and 15. Half were inthe schools string orchestra and had one to five years training in classical music; the
rest had no such training or experience. The boys with musical training scored about20% higher on a test of their ability to learn new words and did slightly better at
recalling words after a 30-minute break. No differences were found between the twogroups in a test of visual memory.
A year later, the researchers retested the 45 boys who had been in the orchestra,including 9 who had dropped out, and 17 boys from the nonmusician group who had
joined the orchestra. These 17, who had significantly lower verbal memory scores on
the previous test, had made the greatest progress over the course of the year. Thosewho stayed with the orchestra also improved their scores, while those who had
dropped out showed no improvement - but their performance was still better thanthose who had never played. The researchers suggest that music training during
childhood helps reorganize/develop the left temporal lobe, facilitating the cognitiveprocessing that occurs there, namely, verbal memory.

Working memory
Working memory is one of the most important concepts in understanding and
improving your memory.
Your working memory capacity is a critical factor in determining your ability
to :
take good notes,
read efficiently,
understand complex issues, reason.
Indeed it may be that it is your working memory capacity that best
measures your intelligence.
Short-term vs long-term memoryWorking memory is a relatively recent term, a refinement of an older concept - that
of short-term memory. Short-term memory was called thus to distinguish it from
"long-term memory" - your memory store.
One important difference between the idea of short-term memory and workingmemory, is that short-term memory was conceived of as a thing. Different from
long-term memory (variously analogized as a library, a filing system, a computer)
chiefly in the duration of the records it held. But working memory, as its namesuggests, is now conceived more as a process than a thing. A state of mind. A
pattern of activation.
Working memory contains the information of which you are immediately
aware.
To put information into our memory store, it must ... be worked on - i.e., be held inworking memory. To get information out of the memory store - to remember
something - it must again be in an active state - be in working memory. How can weknow what we remember if we're not conscious of it?
However, you can only keep something "active" for a very short time without your
conscious attention. It is this which so limits working memory capacity.

Probably the most widely known fact about working memory is that it can only hold
around seven chunks of information (between 5 and 9). However, this tells us little
about the limits of working memory because the size of a chunk is indeterminate.
1 2 3 4 5 6 7 are seven different chunks - if you remember each digit separately (as
you would, for example, if you were not familiar with the digits - as a young child
isn't). But for those of us who are only too well-versed in our numbers, 1 through to7 could be a single chunk.
Recent research suggests however, that it is not so much the numberof chunks thatis important. What may be important may be how long it takes you to say the words
(information is usually held in working memory in the form of an acoustic - sound-based - code). It appears that you can only hold in working memory what you can
say in 1.5 2 seconds. Slow speakers are therefore penalised.
Your working memory capacityWhat we term "working memory" contains several functions, including the "central
executive" which coordinates and manages the various tasks needed. The extent towhich working memory is domain-specific (different "working memories", if you like,for different sensory and cognitive systems, such as language, spatial memory,
number) is still very much debated. However, at a practical level, we may think ofworking memory as containing several different components, for which you have
different "capacities". Thus, your capacity for numbers may well be quite differentfrom your capacity for words, and both from your capacity for visual images.
