INTROSPECTIVE RESEARCH:
VERBAL PROTOCOLS
CHAPTER 3
3.1Introducing
Introspective Research
HOW DO YOU FIND OUT WHAT I’M THINKING? Ask!
How do you define/analyze human emotional/mental
states?Introspective techniques
sources of information about other minds
Asking participants to delve into their own states of consciousness and verbally report on cognitive, affective or social aspects of that
consciousness is the technique used in the introspective studies.
HOW DO YOU USE INTROSPECTIVE TECHNIQUES?
1. Set a task.2. Ask participants to report on
what their brains/hearts are processing as they carry out the task.
Example: solving an arithmetic problem…you mutter to yourself as you solve it….
FÆRCH AND KASPER’S INTROSPECTION IN SECOND LANGUAGE RESEARCH (1987)
Test-taking and validation
Translation Reading Problem-
solving Error analysis Motivation etc
Covers introspective studies in:
LOOKING BACK…
20th centuryWilliam James, Titchener, James
Joyce,Marcel Proust and Virginia Woolf
Within a few years: Under attack by Watson ‘’…untrustworthy for scientific purposes…’’
BehaviorismAbandoned for about 50 years
Ericsson and Simon’s Verbal Protocols (1984,1993)
psychological studies needed to be designed in respect to a model of mental process
formulated such a model based in the basis of information processing theory
Critical feature: assumes a multiple memory model comprising both short-term and long-term memory stores and presumed mechanisms by which they are activated
PRINCIPLES FOR INTROSPECTIVE STUDIES Time intervening between mental operations
and report is critical and should be minimized as much as possible
Verbalization places additional cognitive demands on mental processing that requires care in order to achieve insightful results
Verbal reports of mental processes should avoid the usual social conventions of talking to someone
PRINCIPLES FOR INTROSPECTIVE STUDIES (CONT.) There is a lot of information in
introspective reports aside from the words themselves. parallel signals
Verbal reports of automatic processes are not possible. Such processes include visual and motor processes and low-attention, automatized linguistic processes such as the social chat of native speakers
Research should be based on a model of mental processes that allows predictions about how mental operations will be organized under various conditions
THREE LEVELS OF VERBAL REPORT
Report and the task
Information Example
1Talk-alouds
Report is concurrent with the mental task
linguistically encoded, can be directly stated
Talking aloud while thinking on how to spell a word
2Think-alouds
Report is concurrent with mental task
not already linguistically encoded, thus requires linguistic encoding
Describing what a corkscrew looks like
3 Retrospective
studies
Report is subsequent to mental task
consists of selected foci, descriptions, explanations and interpretations
Reporting a route you travelled
POINTS TO NOTE… Solo/ self-report type
o One is both a participant-subject and analyst
o Example: diary studies, Introspective record language learning impressions
Recordingaudio/video –for later analysisSolo – recordBig class: in pairs, students note down what their partner say – language lab
3.2Experiencing Introspective
Research
GENERAL PRINCIPLES Principle 1- Always use a recording
device.
Principle 2 – Think aloud. Don’t talk.
Principle 3 – Do not be too directive in instructions to participants.
ALL TALK AND NO PLAY MAKES TOO SLEEPY
Sit in pairs Anagram - LIPYMS Participant talk aloud solving the anagram Researcher write down. Reverse roles
BRAINWORK… Were there any problems in solving the
anagram? Were the problems clear from the talk aloud
procedures? Did the two participants use different strategies? Would you use a new strategy if you were to do
it again?
3.3Compiling
Introspective Data
Mostly recorded + notes
Transcribe data from the recording and integrate the notes you have made
Segmenting each segment – a short thought unit, which will be coded and analyzed
ANALYZING INTROSPECTIVE DATA
ANALYSIS OF VERBAL PROTOCOL‘Solving Anagrams’ task types:1. Task Type A : (NPEHPA = HAPPEN)2. Task Type B : (ALPHABET = BET,
BEAT, TAB, PEAL, TABLE)3. Task Type C :
(TEAR, SUN, TRUANT, RESTART = RESTAURANT)
4. Task Type D : (RATS + (?) (word meaning begin) =
RATS + (T) (word meaning begin) = START)
STEPS IN PROTOCOL ANALYSIS1. Responses are transcribed, segmented
and arrayed in the order produced.2. Codes are devised.3. Codes are assigned to response
segments.4. Codes sequences and combinations
are examined for patterns.5. Coding combinations are compared.6. Combinations of codes and coding
classes are examined to see if types of participant strategies can be identified.
CODING LANGUAGE DATA
Coding scheme(Ericsson and Simon, 1987)
Constraint Type (C-type) – Responses are those in which
the participant uses her knowledge of possible letter sequences in English as a
guide for constructing longer sentences.
C-types responses often appear as ‘spelling out’ of
possible letter sequences and letter positions.
Alternative Type (A-type) – Responses are those in which the participant pronounces a
sequence in an attempt to find a sound match in lexical
memory. A-type responses often
appear as ‘sounding out’ of possible syllables or words.
DESIGNING YOUR OWN INTROSPECTIVE RESEARCH STUDY.
1. Free-form responses2. Given orally by the participant3. Elicit cognitive process4. Carry out a specific task5. Take place within particular dimensions
and limited duration6. Produced during or shortly following
out of the task
AREAS OF INTROSPECTIVE STUDY1. Solving logic problems2. Solving a maze3. Crossword puzzle working4. Making word associations5. Completing cloze-type passages6. Ordering scrambled
sentences/paragraph
INTERPRETING INTROSPECTIVE RESEARCH1. Review the objections to introspective
studies.2. Check if the researcher has recognized
the potential problems of such studies.3. See if the researcher has tried to
minimize the impact of these problems.
OBJECTION A -INTROSPECTION ON THINKING PROCESS OF ANY TYPE IS EITHER IMPOSSIBLE OR UNFEASIBLE.
Suggestions:1) Give lots of practice2) Exercise care in choosing introspective tasks
that do not require participants to deal with introspections of higher order, highly automized linguistic processes.
OBJECTION B – EVEN IF INTROSPECTION ON MENTAL STATES IS POSSIBLE OF INTEREST TO LANGUAGE EDUCATORS, INTROSPECTIVE REPORTS ARE BOUND TO BE UNRELIABLE
Issue : RELIABILITY1. Participants’ access to the mental processes
that he/she is trying to articulate.2. Researcher’s instructions, examples or
training is bias. 3. Verbal reporting getting in the way of mental
processing and cause it to be something other than what it would be if there was no requirement to verbalise involved.
SIGNIFICANCE OF INTROSPECTION AS A
SCHOLARLY FOCUS
Plato and Aristotle as early practitionersReasoning, thought and truth
William James (father of modern psychology
Introspective observation is what we have to rely on first and foremost and always. The word introspection need hardly be defined – it means, of course, looking into our own minds and reporting what we there discover’ (Jamesb1890: 185)
Played a major role in psychology in the first two decades of the twentieth century.
Was short-lived, held to be of doubtful validity and overtaken by behaviorism.
‘Verbal protocols are never mentioned as a technique for data collection in books on research methodology’ (Cavalcanti 1987)
U-turn :- since that time, introspective research blossomed (admittedly somewhat biased) ‘verbal reports are now generally recognized
as major sources of data on participants’ cognitive process in specific tasks (Ericsson and Simons 1993)
REFLECTING ON INTROSPECTIVE RESEARCH Wide variety of different types. Any verbal protocol study can be
marked as being of one type or another within each category.
Variety of different uses.
Classification n of verbal protocol data types by Fearch and Cassper. (pg 77)
Payoffs (pg76)
SUMMARY Introspective study:- moved from
enthusiastic endorsement to abandonment to enthusiastic resurrection. (rise/fall/rise)
Remind us that:- choice of research paradigms is a matter of fashion as much as of objective analysis.
It is on the rising tide of acceptance and enthusiasm.
Currents studies:- respond to some earlier critismValidity and reliability
Many caution have been issued and research procedures have been prescribed – minimizing slack.
In sum – What for valid and reliable finding? Design studies based on mental process Incorporate proper warm-up activitiesCareful task instructionAppropriate monitoring of participants
