Examine a recent court case in light of research on eyewitness testimony. Were the procedures used by the police/prosecutors likely to produce accurate testimony from the witness? How might this have influenced the outcome of the trial? Include information on the court case. It should not be a court case where video evidence and eyewitness testimony were presented.
**should be one and a half page to two pages double-spaced in APA format.
Learning Objectives: By the end of this presentation, you will be able to…
describe the various sources of information from which memories are constructed; identify the source responsible for constructing memory in Barlett’s “War of the Ghosts” study
explain how source misattribution in Jacoby’s “Famous Overnight Experiment” illustrates that memory is constructed from various sources.
define and describe the relationships among: expectations, schema, script and stereotype; explain how the “Office” and “Rumor” Studies demonstrate the role of expectancies in memory construction.
discuss memory construction in the broader context of challenges the mind must overcome and identify implication for false memories and confidence
Constructing Memories
I. Introduction
A. Createmem Astound Demo
B. A Classic Illustration: Bartlett’s (1932) “War of the Ghosts” Experiment
British participants read a Canadian Indian folktale…
over a period of time (up to 6 years), participants repeated the tale and the content of their repeated reproductions was analyzed.
Results: The participants remembered the gist of the story but made changed unfamiliar parts of the story to fit their own cultural expectations. E.g…

C. Memory Construction Occurs With Each “Retrieval” (a misnomer) By Combining Info From Various Sources …
the original event
knowledge and expectations about such events
post-event information
Constructing Memories
II. Constructing Memories From Multiple Sources: Source Monitoring Error
memories are constructed from the original event plus other sources, as illustrated by source monitoring error (aka source misattribution)-misidentifying the source of a memory
Constructing Memories
II. Constructing Memories From Multiple Sources: Source Monitoring Error
Jacoby et al’s (1989) “Becoming Famous Overnight” Study…
procedure: participants read nonfamous names; ½ given immediate test to ID famous names with old & new nonfamous names as foils; ½ given same test after 24 hours
results: more names from original list incorrectly identified as famous in delay condition
interpretation: after delay, familiarity misattributed to fame
Constructing Memories
III. Expectations Are a Major Source of Memory Construction
A. Schemas
From his War of the Ghosts research, Bartlett proposed the concept of schema-a cognitive framework that helps organize and interpret information
schemas underlie our expectations.
Brewer & Treyens’ (1981)”Office Study” demonstrates the influence of schemas in memory …
Constructing Memories
Brewer & Treyens’ (1981)”Office Study”…
Participants were asked to wait in experimenter’s “office” for a short time.
Later they were asked to list the items they remembered being in the room. Can you?
Results: participants remembered schema-consistent items hat were present (desk) and that weren’t (books) but not items that were inconsistent with schema (wine bottle, picnic basket).
III. Expectations Are a Major Source of Memory Construction
A. Schemas
From his War of the Ghosts research, Bartlett proposed the concept of schema-a cognitive framework that helps organize and interpret information
schemas underlie our expectations.
Brewer & Treyens’ (1981)”Office Study” demonstrates the influence of schemas in memory
schemas explain the false memories in our opening demo; we have schemas for sleep, chair and sweet.

III. Expectations Are a Major Source of Memory Construction
A. Schemas
B. Scripts- schemas for a sequence of actions are called (e.g. dentist, restaurant, laundry)
C. Stereotypes-schemas for groups of people
Allport & Postman’s (1947) “Rumor Study” shows how memory is distorted by stereotype…
Constructing Memories
IV. Like Other Cognitive Processes, Memory Construction Is a Shortcut That Overcomes Environmental Ambiguity
Recall that the seemingly impossible challenge the mind must overcome is ambiguity in the environment.
Recall we overcome this challenge effortlessly using satisficing shortcuts (“heuristics”)
Memory Construction is such a shortcut; it “Fills in the Blanks”.
A byproduct of satisficing shortcuts is errors (e.g. Muller-Lyer), here false memories
because the same constructive processes that produce accurate memories also produce false memories, we are equally confident in accurate and false memories (e.g. sleep, chair, sweet)

Learning Objectives: By the end of this presentation, you will be able to…
describe Loftus’ studies demonstrating how the power of suggestion plays a role in the misinformation effect and in creating false memories.
describe the history of unintentional memory manipulation in therapy; describe how memories might be intentionally manipulated to change present maladaptive behavior.
describe findings from the innocence project on the nature and rates of errors in eyewitness testimony.
describe cognitive processes that contribute to eyewitness error and how police procedures inadvertently capitalized on these processes.
