Chapter 8MEMORY
No painful recollections so they won’t have anger
possible positive characteristic of no memory
Persistence of learning over time through the storage and retrieval of information
MEMORY
Dad could not lay down new memories but had a large ability to remember
David Myers father and son
After seeing faces for 10 seconds we are able to recognize 90% later
Haber’s study
Unconscious recognition
This is an elephant. You would no for sure if you had seen the full figure earlier because you would remember the similar shape
Processing of information into the memory system
Encoding
Retention of encoded information over time
Storage
Process of getting information out of memory storage
Receive email
retrieval
Sensory memory Short-term memory Long-term memory
Atkinson and Schiffrin
Immediate very brief recording of sensory information in the memory system
Sensory memory
Momentary photographic memory When George Sperling flashed a group of letters similar to this for one-twentieth of a second, people could recall only about half of the letters. But when signaled to recall a particular row immediately after the letters had disappeared, they could do so with near-perfect accuracy.
activated memory that holds a few items briefly, such as the seven digits of a phone number while dialing, before the information is stored or forgotten
short-term memory
the relatively permanent and limitless store-house of the memory system. Includes knowledge, skills, and experiences
long-term memory
Unconscious encoding of incidental information (space, time, frequency) and of well-learned information (word meaning)
automatic processing
Encoding that requires attention and conscious effort
effortful processing
The conscious repetition of information, either to maintain it unconsciously or to encode it for storage
rehearsal
The more he practiced nonsense syllables on day one , the less he needed to learn on day 2
The more time we spend learning novel information, the more we retain
Ebbinghaus’ study
The tendency for distributed study or practice to yield better long-term retention than is achieved through massed study or practice
spacing effect
They will be able to retain more information due to the spacing effect
Why is giving a student 4-5 days to study important?
Repeatedly being tested –more learning than practice
Testing effect
Space out your study to retain more information
Self-assessment
beat cramming
Our tendency to recall best the last and first items in a list
serial position effect
They should put the hardest words first The next difficult words at the end The easiest words in the middle
advice to Spanish teacher
Last items are still in working memory, and people briefly recall them especially quickly and well
recency
After a delay, recall is best for the first items
primary effect
Encoding of picture images
visual encoding
Encoding of sound (especially words)
acoustic encoding
Encoding of meaning (including the meaning of words)
semantic encoding
The time you spend thinking about material, reading, and relating it to previously stored material
Wickelgren
Relating new information to previously stored material or experiences
self reference effect
Mental pictures; powerful aid to effortful processing, especially when combined with semantic encoding
imagery
It allows us to remember it longer because instead of thinking about it we know exactly what it looks like
Imagery in visual encoding
People tend to recall events more positively than they judged them at the time
rosy retrospection
You will most likely just remember the high points
Why might a vacation you did not like seem better now than before?
Memory aids; especially these techniques that use vivid imagery and organizational devices
mnemonic device
Memorized jingly so you can count by peg words. We are able to visually associate other things with peg words
peg-word system
Organizing items into familiar, manageable units, often occurs automatically
EXAMPLES: chess master (recall positions quickly)
chunking
Creating a word (a form of chunking) to learn it better
How is chunking applied
ROY G BIV
ENCODING
Organization helps to recall time and accuracy
Bower
Momentary sensory memory of visual stimuli, photographic/picture; image memory lasts no more than a few tenths of a second
iconic memory
Showed all available for recall but only for a couple seconds. Tone sound for which line to read but if delayed recall less.
Sperling’s
Momentary sensory memory of auditory stimuli; if attention is elsewhere, sounds and words can still be recalled within 3 or 4 seconds
echoic memory
Kids can recall the last few words because they were unconsciously listening
How can a teacher can get tricked?
After 3 seconds only recalled half of the time after 12 seconds they seldom recalled any of it
Peterson and Peterson
STM can usually store 7 pieces of information (give of take 2)
George Miller’s 7 plus or minus 2
No, because it is out of the number of short term memory (10 numbers instead of 9)
Could people my age remember phone numbers with area codes prior to cell phones?
Repeat 50 random digits backward Could recite pi with prompt of 10 numbers
Rajan Madhevan’s memory
Memories are not stored in only one spot
Lashley
serotonin
What neurotransmitter is released when learning occurs?
Increase the synapse’s firing potential after brief, rapid stimulation
Long Term Potentiation
They are trying to develop drugs that boost glutamate and CREB to increase long term potentiation/connections to it
Expanding memory = MORE MONEY
Drug companies
No because working memory had no time to consolidate the information into long term memory before lights went out
Do football players and boxers remember when they have concussions?
Clear memory of an emotionally significant moment or event
flashbulb memory
It is a flashbulb memory We will never be able to forget it
Where were you on 9/11
hippocampus
Brain structure on memories
Loss of memory
amnesia
Memory of facts and experiences that one can consciously know and “declare” (a declarative memory)
explicit memory
Retention independent of conscious recollection
implicit memory
FIGURE 8.14
Neural center located in limbic system and helps process explicit memories for storage
hippocampus
Extends from rear of brainstem, keep role in forming and storing implicit memory created by classical conditioning
cerebellum
Recall nothing (explicitly) from first three years
infantile amnesia
Measure of memory in which the person must retrieve information learned earlier as on a fill-in-the-blank test
recall
Memory measure that assesses the amount of time saved when learning material the second time
relearning
Measure of meaning in which a person needs only identity other previously learned (multiple choice test)
recognition
Anchor points used to access target memories later
retrieval cues
Activation (often unconsciously) of particular associations in memory
EXAMPLE: rabbit- hare
priming
Context effect-words heard under water will be remembered better under water
context effect
Eerie sense that you’ve been here before cues from current situation may sub consciously trigger retrieval of an earlier experience
Déjà vu
Remember things by going back to where it happened (alcohol disrupts storage but may remember if drunk again
Bower
Alcohol disrupts storage but the memories may come back the next time they are drunk
When it comes to alcohol, when does the view work and when does it not?
Tendency to recall experiences that are consistent with ones current mood
mood congruent memories
The traumatic event would be what was remembered because that mood would travel with them during exams
Traumatic before exams?
FORGETTING absent-mindedness Transience BlockingDISTROTION Misattribution Suggestibility BiasINTRUSION Persistence
Daniel Schacter’s 7 sins of forgetting
Oops! Forgot my wallet!
Inattention to details leads to encoding failure
Mind is elsewhere as we lay down car keys
Absent-mindedness
Storage decay overtime After we part ways with classmates unused
information fades
transience
Inaccessibility of stored information
blocking
Confusing source of info
misattribution
Lingering effects of misinformation
Suggestibility
Belief-colored recollections (current feeling vs. initial)
Bias
Unwanted memories
Persistence
USE IT OR LOSE IT
what does this tell you about what you will remember from high school?
Forgetting Retrieval issues
tip of the tongue forgetting
Disruptive effect of prior learning on recall of new information
example: new lock combination is forgotten because original code is stuck in head
Proactive interference
Disruptive effect of new learning on recall of old information
One can’t remember old locker combination because new one is too prominent in their head
retroroactive interference
Old information facilitates learning of new information
Latin may help learn French
positive transfer
He thought he wanted to go and his mom wanted him to stay but really it was the other way around
Haber
We repress painful memories
Freud on self concepts
Basic defense mechanism that banishes anxiety, arouses thoughts, feelings, memories from consciousness
repression
They block it out
Explain how memory construction applies to car accidents
Incorporating misleading information into one’s memory of an event
Yield vs. stop signs Hammers vs. screw drivers coke can vs. peanut can
misinformation effect
Imagining things More likely to think they were actually done
imagination inflation
Attributing to the wrong source an event which we had experienced heard about, read about, or imagined
source amnesia
They could be talking about the wrong person
Source amnesia gets kids in trouble
If quest landed with neutral words provide accurate recall
Children’s eyewitness recall
Falsely recall experiences Remember the false thing Describe the non-existent scenario Construct false memories
false memories of childhood trauma
Study repeatedly Make the material meaningful Activate retrieval cues Use mnemonic devices Minimize interference Sleep more Test your own knowledge to rehear it and to
determine what you don’t know
7 tips of how to improve memory
Chapter 9THINKING
AND LANGUAGE
all the mental activities associated with thinking, knowing, remembering, and communicating.
cognition
a mental grouping of similar objects, events, ideas, or people.
concepts
a mental image or best example of a category. Matching new items to a prototype provides a quick and easy method for sorting items into categories
prototype
What people categorize the face as
Olivier Corneille
a methodical, logical rule or procedure that guarantees solving a particular problem. Contrasts with the usually speedier—but also more error-prone—use of heuristics
algorithm
a simple thinking strategy that often allows us to make judgments and solve problems efficiently; usually speedier but also more error-prone than algorithms.
heuristic
a sudden and often novel realization of the solution to a problem; it contrasts with strategy-based solutions.
insight
a tendency to search for information that supports our preconceptions and to ignore or distort contradictory evidence.
Ex: women get pulled over by police more than men
Confirmation bias
the inability to see a problem from a new perspective, by employing a different mental set.
Fixation
a tendency to approach a problem in one particular way, often a way that has been successful in the past.
Mental set
judging the likelihood of things in terms of how well they seem to represent, or match, particular prototypes; may lead us to ignore other relevant information.
Representativeness heuristic
SMART
estimating the likelihood of events based on their availability in memory; if instances come readily to mind (perhaps because of their vividness), we presume such events are common.
Availability heuristic
the tendency to be more confident than correct—to overestimate the accuracy of our beliefs and judgments.
overconfidence
clinging to one’s initial conceptions after the basis on which they were formed has been discredited.
Belief perseverance
Still killing America
an effortless, immediate, automatic feeling or thought, as contrasted with explicit, conscious reasoning.
intuition
the way an issue is posed; how an issue is framed can significantly affect decisions and judgments.
framing
Spoken, written, or signed words and the way we combine them to communicate meaning
language
“the jewel in the crown of cognition”
Pinker and Language cognition
You will learn the information and hear it
Listen to teachers
Get people’s attention Get people to go things Maintain relationships
3 reasons people make sounds
Transfer meaning from one mind to another
Language allows us to…
Smallest distinctive sound unit (letters) Basic set of sounds
Definition of phonemes
Sign language has phoneme like building blocks
Bellugi on sign language
The smallest unit of language that carries meaning
Examples: bat, -ed, I, a, yes
morpheme
System of rules that enables us to communicate with and understand others
grammar
Rules we use to order words into sentences
syntax
Set of rules by which we derive meaning from morphemes, words, and sentences in a given language
The study of meaning
semantics
This is true because some people without educations may say “ain’t got none” which is a double negative when the correct way to say it is “doesn’t have any”
Less educated speak ungrammatically
The small sounds of the phonemes combines with the prefixes and suffixes of morphemes create words
Phonemes+morphemes=words
You know about 60,000-80,000 words but don’t use them all
You use about 150
how many words do you know
Discriminate speech sounds Read lips
At four months old
Ability to comprehend speech
Receptive language
Segmenting spoken sounds in other languages into words
At 7 months old
fidichs
Ability to produce words
Productive language
4 months, spontaneously utters various sounds
Unrelated to anything
Babbling stage
The child begins to babble sounds that sound more like the home language such as “mama”
At 10 months
MOMMADADA
1-2, speaks in single word phrases
One word stage
Uses mostly noun sound verbs Age 2, 2 word statements
Telegraphic stage/2-word stage
Language development
Modeling and copying
imitation
Positive/negative Congratulations (hug) when correct
reinforcement
Paring sights with sounds of words
association
We are the same as animals in terms of operant conditioning
Skinner
Chomsky believes that development is not all about experiences as a child and some is biological
Chomsky thinks of Skinner
Prewired language “switchbox”
Language acquisition device
Same grammar or building blocks as other countries
Universal Grammar
childhood is good time to master aspects of language
Critical period
Nature VIA nurture Important to learn new language during
childhood
Mayberry
Learning language
Impaired use of language
aphasia
Language expression, directs muscles involved in speech
Broca’s area
Language reception, comprehension, expression
Wernicke’s area
Reading aloud
Angular gyrus
Language processing areas
Brain activity
The prime years to learn new things is during early childhood or early teen years
Process language and information
Your brain processes language by dividing its functions into sub functions, same for everything
As you read
Whorf’s hypothesis that language determines the way we think
Linguistic determination
They have no past tense They can’t think in the past
Hopi indian
When asked to describe self in different language
Self-discrimination went with language
Ross, Xun, and Wilson
There are hand signals for strike outs A hand signal for a foul in basketball
Sports sign language
Thinking about it stimulated the brain
Liu Chi Kung
imagination
Beginning to study sooner, spent more time at it, and beat the others
Process simulation
Thinking and language
Baboons know every troop member’s voice Pigeons can sort objects
Smart animals
Apes exhibit foresight by storing tool to use for food next day
foresight
They are natural tool users
Chimpanzee
Cultural transmission
Chimp bests humans
Comprehension of numbers to 6, they speak a number of objects, sort and announce sums
Monkey communication
Apes gain the vocabulary with difficulty Other animals do same for rewards People see what they want to see Different meaning may not be different to
chimps
Ape communication
Different alarm cries for different predators
Gestures enable communication
Trained adopted baby Other people that signed said it worked
Washoe
90%
What percentage of people who sign understand chimps?
Early life is good to learn language
critical period applies to pygmy chimps
