Reconstructive memory

Our memories aren’t perfect




We forget things
We actively construct memories from bits and
pieces
More than that, we may actually make some
things up sometimes (to fill in gaps)
How many people thought “sleep” was on the
list?
Reconstructive memory

Applied situation

Eye witness testimony

What affects the
memory of the
event?




What they saw
How long ago
What sort of cues
do they get
How they are
asked about it?!
Class experiment

Today going to go over the design and
procedures for the class experiment.

I have put the materials together and posted them
on the web site
• Syllabus, class experiment, download from the green
box

find some volunteers (2 people)
collect some data
Bring the data back to class on Monday
I will compile and analyze the results
Based on this experiment and these results
you will produce an APA style research report

Response sheets
Two consent forms
Debriefing sheet
Class experiment


Participants will be given a brief description of an
automobile accident
Later they will be asked to questions about the
accident
Class experiment
Some participants will see a “picture” of the
accident, others will only read the description
"I was standing on the Northwest
corner of the intersection. Car 1
was approaching the intersection
from the North at about 30 mph.
Car 2 was approaching the
intersection for the East at about 30
mph. Neither car slowed as they
approached the intersection. Car 1
bumped Car 2 as it was going
through the intersection. I think Car
1 may have been running a red
light."
contacted
smashed
Class experiment
Some participants will see a “picture” of the
accident, others will only read the description
A - H run condition A
I - R run condition B
S - Z run condition C
Class experiment

Following presentation ask your participant to:




Please rate how much you think Car 1 is responsible
(“at fault”) for the accident based on the eyewitness
account you just read.
How certain are you that your judgment in (1) above
is correct?
Please rate whether you think that there was broken
glass at the accident scene
How certain are you that your judgment in (3) above
is correct?

Intuitions
Literature review: For your paper
• There are three required readings (see web page).
• You must include these in your introduction
• Find at least 1 additional article to include in your
introduction
