[Class and Section Number]
Introduction
Bounded Rationality –
Cognitive limitations
prevent humans from
being fully rational
Biases – Mistakes that
influence judgment
What is a Rational Decision?
What is a Rational Decision?
Rational Decision Making
 Define the problem
 Identify criteria necessary
to judge
 Weigh the criteria
 Generate alternatives
 Rate each alternative
 Compute optimal decision
Biases: Overconfidence
Overconfidence – The bias to have greater
confidence in your judgment than is warranted
based on a rational assessment.
Biases: Anchoring
Anchoring – The bias to be affected by an initial
anchor, even if the anchor is arbitrary, and to
insufficiently adjust our judgments away from it.
10 – 100 – 200?
The size of your anchor does matter.
Biases: Framing
Framing – The bias to be systematically affected
by the way in which information is presented.
 Positive or negative?
 Influence of frame
Biases in Decision Making
Contemporary Developments
Bounded Willpower –
We give greater weight to
present concerns over
future ones.
Contemporary Developments
Bounded Self-interest – Our own behavior is
influenced because we care about the outcomes
of others.
Contemporary Developments
Bounded Ethicality – Our
ethics are limited in ways
that we don’t realize.
Bounded Awareness –
There is a broad array of
focusing failures that
affect our judgments.

Memory
[Instructor Name]
[Class and Section Number]
Introduction to Memory
Working Memory
Working Memory – The ability to hold information
in mind for a brief time and work with it.
Semantic Memory
Semantic Memory – Your storehouse of more or
less permanent knowledge.
Episodic Memory
Episodic Memory –
The ability to
remember the
episodes of your life.
Collective Memory
Collective Memory – The kind of memory that
people in a group share (whether family,
community, schoolmates, citizens of a state or a
country).
Stages of Memory: Encoding
Encoding – The initial experience
of perceiving and learning events.
Distinctiveness
Recoding
Recoding – Taking
information from one form
and converting it in a way
that makes sense to us.
Please
Excuse
My
Dear
Aunt
Sally
Stages of Memory: Storage
Memory Trace (engram) – The change in the nervous
system that represents our experience.
Consolidation – The neural changes that occur over
time to create the memory trace of an experience.
Storage
Stages of Memory: Retrieval
Encoding Specificity Principle – The effectiveness of
retrieval cues.
Available – All information stored in memory.
Accessible – The information we are able to retrieve.
Measuring Retrieval
Production Tests
 Generation of studied info
 Example = Free Recall
Recognition Tests
 Selection of studied info from
aggregate info
 Example = Multiple Choice
True/False
