Lecture 17 – Psyco 350, B1
Fall, 2011
N. R. Brown
Outline
1. Autobiographical Memory – Part 2
2. The Partner Discrepancy – Part 2
Psyco 350 Lec #15– Slide 2
Studying E-to-E Organization: Event-cueing
Brown & Schopflocher (1998)
General Method:
Cueing event: auto event1 [E1]

Cued event:
auto event2 [E2]
Assumption:
E1 & E2 often associated
Implication:
pattern of E1  E2 relations reflects underlying
organization
Brown & Schopflocher (1998)
Two groups (during Phase 1 only):
word-cued group
important-event group
Five Phases:
1. generate cueing events
2. event-cueing task
3. relations-coding task
4. event-dating task
5. Importance-rating task
Phase 1
Important-Events Condition
• E1 acquisition: Prompt
event1 [E1]
• task: to recall important personal event
• (e.g., my mom and telling me that my dad was
going to move out)
• 14 trials
• Retrieval time was measured
• Memories (E1s) were typed
• 72 undergrads
Phase 1
Word-Cue Condition
• E1 acquisition: Cue word
event1 [E1]
• task: to recall a personal event related to the
cue word
• CAR
when I was 15, I stole a car.
• 14 nouns
• Retrieval time was measured
• Memories (E1s) were typed
• 73 undergrads
Phase 2
Event-cueing Task
• Identical for both important-events and wordcue conditions
• E2 acquisition: event1 [E1]
event2 [E2]
• My mom and dad telling me my dad was going
to move out [E1]
Dad leaving a note on my
pillow saying bye [E2] .
• All E1s served as cues
• Retrieval time was measured
• Memories (E2s) were typed
Phase 3
Relation-Coding Task
• Identical for both important-events and wordcue conditions
• [E1 & E2] + Relation Menu
Select relation(s)
• All event pairs scored
• Unrestricted selection
• Untimed
Phase 3
Relation-Coding Task
• Event A: My mom and dad telling me my dad was
going to move out.
• Event B: Dad leaving a note on my pillow saying bye
–

–
Did event A and B involve the same person or persons?
Did event A and B involve the same activity?
Did event A and B involve the same location?
Did one of the events cause the other?
Is one of the events part of the other?
Are both events part of a single broader event?
Are event A and event B related in some other way?
Phase 4
Event Dating Task
• Identical for both conditions
• Ex
Date for Ex
• My mom and dad was telling me my dad was
going to move out
June 30, 1986
• All events dated
• Random presentation
• Untimed
Phase 5
Importance Rating Task
• Identical for both conditions
• Ex
Importance rating for Ex (1-to-5 scale)
• My mom and dad was telling me my dad was
going to move out
5
• All events rated
• Random presentation
• Untimed
Horizontal Organization: Two General Positions
Special Narrative Processing Position
• created ONLY by narrative processing given to
important life stories
Matter-of-Course Position
• normal memory processing
• higher-level cognitive processing
– planning, evaluation, comprehension
• narration
Competing Predictions
Narrative Position:
• Only important events will frequently cue
cluster mates.
Matter-of-course Position:
• Important and unimportant events will
frequently cue cluster mates
B&S Results: Event Age
B&S: Results
Defining clustered Pairs:
• Clustered Pairs:
– Either cause, subevent, or "same story" relation
indicated.
• Nonclustered Pairs:
– Neither cause, subevent, nor "same story" relation
indicated.
% Clustered:
• Important-Events Group:

Summary
Main Claims:
• Event clusters very common
• Clustered events:
– causally & thematically related
– temporally proximate
Evidence:
• 80% clustered
• RT: clustered < nonclustered
• Age s: clustered << nonclustered
• Overlapping story elements:
– clustered > nonclustered
Interpreting Event Clusters
• A Strong Narrative Position
• Event clusters are narratives.
• Narrative processes necessary for creation/
maintenance of autobiographical memory.
Interpreting Event Clusters
• A Comprise Position
• Clustering prompted by:
– temporal contiguity
– similarity
– causal reasoning
– goal directed planning and evaluation
• Narrative creation/maintenance facilitated by
clustering
Retrieval Processes in Autobiographical
Memory (Uzer, Lee & Brown, 2011)
Models of Autobiographical memory (AM)
assume two retrieval strategies:
– Generative retrieval
– Direct retrieval
Generative retrieval has been assumed as
a normative form of retrieval
Introduction
Retrieval processes: Reaction time (RT)
Studies have shown:
– Concrete nouns < emotion terms
– Personal periods < common activities
– Common activities < general actions
Introduction
RT differences:
– As an index of effort required to generate
appropriate cues
– Generation is easy and fast, when cue
accesses to associative links
– Generation is slower and harder, when
cue must be reformulated to access to
associative links
Introduction
Dual Retrieval Strategies Approach:
– RT differences reflect multiple retrieval
strategies
– RTs reflect weighted blend of generative
and direct retrieval modes
Current Questions
• How common are direct and generative
retrieval?
• Would retrieval strategy change as a
function of task conditions (e.g., the
types of cues provided)?
• Would RT differences still occur holding
retrieval strategy constant?
Exp 1: Method
40 U of A undergraduate students
Within-subjects design
Procedure: Cue word :
“specific
personal event that is related to the cue
word”
Two types of cue words:
– Concrete nouns (e.g., chair, pencil, book)
– Emotion terms (e.g., shy, happy, sad)
Exp 1: Method
Concurrent verbal protocols:“Think out loud
by verbalizing all your thoughts as you are
thinking them”
Pressing SPACEBAR as memory is retrieved
(RT)
Strategy Report: Participants were asked if
the memory came directly into mind - “Y” for
YES or “N” for NO
Brief written report of memory
Exp 1: Results

Concurrent verbal protocols: Reactivity to
generative retrieval
“Did this memory came immediately to mind”
might create a demand for directly retrieved
memories.
Exp 2: Method

Procedure: Cue-words ---- AM (Identical to
Exp 1.)
Pressing SPACEBAR as memory is retrieved

Exp 2: Method
Strategy Report:
Cond. 1 (Direct): “Did the memory come
immediately to mind” Yes or No responses
Cond. 2 (Generative ) : “Did you actively
search to recall this memory?” Yes or No
responses
Cond. 3 (Both Option): “How did you retrieve
this memory?”
-The memory came immediately to mind
-I actively searched to recall the memory

Exp 2: Issues
Problems:
Participants might be deciding about their
retrieval strategies based on time.
Asking people whether memory directly came
to mind or you searched is confounded with
time.
When you directly retrieve it is fast when you
search it takes time.
Exp 3: Rationale
Another approach: looking at “use of
information”.
Direct Retrieval: You don’t use any
information to find the memory, the
memory comes straight to your mind.
Generative Retrieval: To find the memory
you have to search for/use some type of
information (e.g., people in your life, any
time period, places you have been, etc).
Exp 3: Method

Exp 3: Method
Strategy Report:
Condition 1 (Direct Cond.):“This memory was
triggered by the cue word so I did not have
to use information about my life to help me
recall this memory.” Yes or No responses
Yes: Direct Retrieval
Exp 3: Method
Strategy Report:
Condition 2 (Generative Cond.) : “This
memory wasn’t triggered by the cue word so
I had to use information about my life to help
me recall this memory.” Yes or No responses
Yes: Generative Retrieval

Control:
“Please report your number of lifetime sexual
partners”
Approx:
“Off the top of your head, please provide a rough
estimate of your number of lifetime sexual
partners.”
Enum:
“Please think back over your lifetime starting with
your first sexual partner and count all of your
sexual partners up to and including your most
recent partner.”
Psyco 350 Lec #17– Slide 74
Method -- Tess
2. Indicated estimation strategy – Strategy Menu
I just now thought back over my lifetime and tried to remember and count
each sexual partner.
I made a rough guess, plus or minus a few sexual partners.
It was a very small number, so I just knew.
I keep a running tally of my number of sexual partners and I remembered
this number (for example, I use a diary or I have been keeping track in my
head over time).
I thought about the number of different sexual partners who I’ve been with in
an average year and multiplied by the number of years that I’ve been
sexually active (for example, about 5 a year for 5 years equals 25)
I used some other method to come up with my response. Please specify:

7. Rated bias of the estimate.
In terms of report of my number of lifetime sexual partners,
I think that:
I greatly under-reported
I slightly under-reported
I was accurate in my report
I slightly over-reported
I greatly over-reported my number of lifetime sexual
partners

Research Questions
Psyco 350 Lec #17– Slide 81
Research Questions -- Tess
• Will the strategy difference replicate?
• Mode Effects:
– Will web-based administration decrease the
discrepancy?
– Will web-based administration affect strategy
selection?
• Will self-ratings yield self-incrimination (SI)?
• Will the partner discrepancy & strategy
differences disappear when SIs removed?
Psyco 350 Lec #17– Slide 82
Research Questions -- Tess
Mode Effect:
• Anonymity promotes disclosure.
– Discrepancy: Web < Telephone
• Web conventions (“flaming trolls”) condone
exaggeration.
– Discrepancy: Web > Telephone
Psyco 350 Lec #17– Slide 83
Research Questions -- Tess
• Will instructions affect strategy choice?
• If so:
– Will the instructional effect be a large one?
– Will instructions effect (decreases) the discrepancy?
