The Cognitive Revolution

cognition – how information is processed
and manipulated when remembering,
thinking, and knowing

1950s: psychology resumes focus on the
mind and mental processes

computers: an analogy for the mind/brain
- artificial intelligence (AI)

Thinking



concepts – mental categories used to
group objects, events, and characteristics
Image(mental rep), symbol(words),
concept(label for a class) and
rule(relation)
prototype model – all instances of a
concept are compared to a prototype
(ideal example) of that concept

Steps in Problem Solving
1. Find and frame problem
2. Develop good problem-solving
strategies (subgoals, algorithms,
heuristics)
3. Evaluate solutions
4. Rethink and redefine problems and
solutions over time

Problem-Solving Obstacles

fixation
- using a prior strategy only

functional fixedness
- fixated on usual functions
© 2011 The McGraw-Hill Companies, Inc.
Reasoning

mental activity of transforming
information to reach conclusions

inductive reasoning
- driven by data; bottom-up; specific  general

deductive reasoning
- driven by logic; top-down; general  specific

Reasoning
and Decision Making
© 2011 The McGraw-Hill Companies, Inc.
Decision Making

evaluating alternatives and making
choices among them

attempting to maximize outcome
© 2011 The McGraw-Hill Companies, Inc.
Reasoning and
Decision Making
System I – automatic
 rapid, heuristic, intuitive
System II – controlled
 slower, effortful, analytical
© 2011 The McGraw-Hill Companies, Inc.
Decision-Making Biases
Confirmation Bias

search only for info that supports our ideas
Hindsight Bias

report falsely that we predicted an outcome
Availability Heuristic

predict probability based on ease of recall
Base-Rate Fallacy
 ignore info about general principles
Representativeness Heuristic

make judgments based on stereotypes
© 2011 The McGraw-Hill Companies, Inc.
Critical Thinking



thinking reflectively and productively and
evaluating the evidence
mindfulness – alert and mentally present
open-mindedness – receptive to new ways
of looking at things
© 2011 The McGraw-Hill Companies, Inc.
Emotion and Cognition

moods influence the way we think

bad moods >> use careful logic to solve
problems

good moods >> efficiency, originality,
creativity, ignore irrelevant info

Creative Thinking
Divergent versus Convergent Thinking
Characteristics of Creative Thinkers





brainstorm
flexibility and playful thinking
inner motivation
willingness to face risk
objective evaluation of work

Intelligence

What is intelligence?

definitions of intelligence reflect culture

U.S. – Spearman’s g

measuring intelligence
- validity
- reliability
- standardization

Genetic Influences on Intelligence


heritability
increases with age
Environmental Influences on Intelligence

Variations in Intelligence
Giftedness: usually IQ ≥ 130
 Terman – socially well adjusted and
successful as adults
 importance of innate ability
Intellectual disability: usually IQ < 70



organic versus cultural-familial disabilities
mild, moderate and severe/profound

social, practical)
