4 The Elements of Cognition
Thinking and Intelligence 4/25/2017 The Elements of Cognition Concept: Mental category that groups objects, relations, activities, abstractions, or qualities having common properties. Proposition: A unit of meaning that is made up of concepts and expresses a single idea. Mental Image: Representation that mirrors or resembles the thing it represents. Cognitive Schema: An integrated mental network of knowledge, beliefs, and expectations concerning a particular topic or aspect of the world. Figures from page 191 of Wade, C., & Tavris, C. (2002).

5 How Conscious is Thought?
Thinking and Intelligence 4/25/2017 How Conscious is Thought? Subconscious Processes: Mental processes occurring outside of conscious awareness but accessible to consciousness when necessary. Nonconscious Processes: Mental processes occurring outside of and not available to conscious awareness. ©2002 Prentice Hall ©2002 Prentice Hall

6 Thinking and Intelligence
4/25/2017 Reasoning Rationally Formal Reasoning: Algorithms and Logic Informal Reasoning: Heuristics and Dialectical Thinking Reflective Judgment ©2002 Prentice Hall ©2002 Prentice Hall

7 Thinking and Intelligence
4/25/2017 Formal Logic Deductive Reasoning: A tool of formal logic in which a conclusion necessarily follows from a set of observations or propositions (premises). Inductive Reasoning: A tool of formal logic in which a conclusion probably follows from a set of observations or propositions or premises, but could be false. Figures from pages of Wade, C., & Tavris, C. (2002). Invitation to Psychology, 2nd Ed. Upper Saddle River, NJ: Prentice Hall. ©2002 Prentice Hall ©2002 Prentice Hall

8 Thinking and Intelligence
4/25/2017 Informal Reasoning Heuristic: A rule of thumb that suggests a course of action or guides problem solving but does not guarantee an optimal solution. Dialectical Reasoning: A process in which opposing facts or ideas are weighed and compared, with a view to determining the best solution or resolving differences. ©2002 Prentice Hall ©2002 Prentice Hall

9 Barriers to Reasoning Rationally
Thinking and Intelligence 4/25/2017 Barriers to Reasoning Rationally Exaggerating the Improbable Avoiding Loss The Confirmation Bias Biases Due to Mental Sets The Hindsight Bias The Need for Cognitive Consistency Overcoming Our Cognitive Biases ©2002 Prentice Hall ©2002 Prentice Hall

10 Exaggerating the Improbable
Thinking and Intelligence 4/25/2017 Exaggerating the Improbable Availability Heuristic: The tendency to judge the probability of an event by how easy it is to think of examples or instances. For example, most people overestimate the odds of dying in a plane crash. Dying in an automobile accident is far more likely ©2002 Prentice Hall ©2002 Prentice Hall

11 Thinking and Intelligence
4/25/2017 Avoiding Loss People try to minimize risks and losses when making decisions. Responses to the same choice will differ based on whether outcome is framed as gain or loss. In the example, outcomes are the same in Problems 1 & 2 Figure 6.01 from Wade, C., & Tavris, C. (2002). Invitation to Psychology, 2nd Ed. Upper Saddle River, NJ: Prentice Hall. ©2002 Prentice Hall ©2002 Prentice Hall

12 Thinking and Intelligence
4/25/2017 The Confirmation Bias Confirmation Bias: The tendency to look for or pay attention only to information that confirms one’s own beliefs. Test this rule: If a card has a vowel on one side, it has an even number on the other side. Which 2 cards to turn over? E J 6 7 ©2002 Prentice Hall ©2002 Prentice Hall

13 Biases Due to Mental Sets
Thinking and Intelligence 4/25/2017 Biases Due to Mental Sets Mental Set: A tendency to solve problems using procedures that worked before on similar problems. Mental sets help us solve most problems efficiently Not helpful when a problem calls for fresh insights or a new approach ©2002 Prentice Hall ©2002 Prentice Hall

14 Thinking and Intelligence
4/25/2017 The Nine-Dot Problem Connect all 9 dots Use only 4 lines Do not lift your pencil from the page after you begin drawing Figure 7.9a from: Kassin, S. (2001). Psychology, third edition. Upper Saddle River, NJ: Prentice Hall. ©2002 Prentice Hall ©2002 Prentice Hall

15 Thinking and Intelligence
4/25/2017 The Hindsight Bias Hindsight Bias: The tendency to overestimate one’s ability to have predicted an event once the outcome is known. Also known as the “I knew it all along” phenomenon. “The older they get the better they were when they were younger.” Jim Bouton, professional baseball player ©2002 Prentice Hall ©2002 Prentice Hall

16 Need for Cognitive Consistency
Thinking and Intelligence 4/25/2017 Need for Cognitive Consistency Cognitive Dissonance: A state of tension that occurs when a person simultaneously holds two cognitions that are psychologically inconsistent, or when a person’s belief is inconsistent with his or her behavior. ©2002 Prentice Hall ©2002 Prentice Hall

17 Thinking and Intelligence
4/25/2017 Intelligence Measuring Intelligence: The Psychometric Approach Dissecting Intelligence: The Cognitive Approach ©2002 Prentice Hall ©2002 Prentice Hall

18 Thinking and Intelligence
4/25/2017 Intelligence Intelligence: An inferred characteristic of an individual, usually defined as the ability to profit from experience, acquire knowledge, think abstractly, act purposefully, or adapt to changes in the environment. g factor: A general intellectual ability assumed by many theorists to underlie specific mental abilities and talents. ©2002 Prentice Hall ©2002 Prentice Hall

19 The Psychometric Approach
Thinking and Intelligence 4/25/2017 The Psychometric Approach IQ scores are distributed “normally” Bell-shaped curve Very high and low scores are rare 68% of people have IQ between 99.7% between Figure 6.02 from Wade, C., & Tavris, C. (2002). Invitation to Psychology, 2nd Ed. Upper Saddle River, NJ: Prentice Hall. ©2002 Prentice Hall ©2002 Prentice Hall

20 The Cognitive Approach
Thinking and Intelligence 4/25/2017 The Cognitive Approach Metacognition: The knowledge or awareness of one’s own cognitive processes. Tacit Knowledge: Strategies for success that are not explicitly taught but that instead must be inferred. ©2002 Prentice Hall ©2002 Prentice Hall

21 Sternberg's Triarchic Theory
Thinking and Intelligence 4/25/2017 Sternberg's Triarchic Theory Components - a.k.a. “Analytic” Comparing, analyzing, and evaluating. This type of processes correlates best with IQ. Experiential - a.k.a. “Creative” Inventing or designing solutions to new problems. Transfer skills to new situations. Contextual - a.k.a. “Practical” Using (i.e., applying) the things you know in everyday contexts. ©2002 Prentice Hall ©2002 Prentice Hall

22 The Origins of Intelligence
Thinking and Intelligence 4/25/2017 The Origins of Intelligence Genes and Intelligence The Environment and Intelligence Attitudes, Motivation, and Intellectual Success ©2002 Prentice Hall ©2002 Prentice Hall

23 Correlations in Siblings’ IQ Scores
Thinking and Intelligence 4/25/2017 Correlations in Siblings’ IQ Scores IQ Scores of siblings were highly correlated, even when they were reared apart. Identical twins have higher correlations than fraternal twins Suggests a genetic link Figure 6.04 from Wade, C., & Tavris, C. (2002). Invitation to Psychology, 2nd Ed.

24 Explaining Group Differences
Thinking and Intelligence 4/25/2017 Explaining Group Differences Within a group with all treated exactly the same, differences may reflect genetics. When one group differs from another, the differences may reflect environmental differences. Figure from: Kassin, S. (1998). Psychology, second edition. Upper Saddle River, NJ: Prentice Hall.

25 Environment and Intelligence
Thinking and Intelligence 4/25/2017 Environment and Intelligence Factors associated with reduced IQ: Poor prenatal care Malnutrition Exposure to toxins Stressful family circumstances Healthy and stimulating environments can raise IQ, sometimes dramatically ©2002 Prentice Hall ©2002 Prentice Hall

26 Attitudes and Intellectual Success
Thinking and Intelligence 4/25/2017 Attitudes and Intellectual Success Asian children score higher on standard math tests than American children. Differences: Americans are more likely than Asians to believe that math ability is innate Americans have far lower standards for their children Asian children value education more highly than Americans Figure 6.07 from Wade, C., & Tavris, C.

28 Thinking and Intelligence
4/25/2017 Animal Intelligence Cognitive Ethology: The study of cognitive processes in nonhuman animals. Studies in cognitive ethology have shown evidence that some animals can Anticipate future events Use numbers to label quantities Coordinate activities with other animals ©2002 Prentice Hall ©2002 Prentice Hall

29 Thinking and Intelligence
4/25/2017 Animals and Language Language is a critical element of human cognition Many animal species can be taught to communicate in ways that resemble language Chimpanzees and bonobos converse using American Sign Language and symbol board systems An African grey parrot has been taught to count, classify, and compare objects using English words Whether these behaviors are language depends on how you define “language.” ©2002 Prentice Hall ©2002 Prentice Hall

30 Thinking About Animal Thinking
Thinking and Intelligence 4/25/2017 Thinking About Animal Thinking Anthropomorphism: The tendency to falsely attribute human qualities to nonhuman beings. Anthropocentrism: The tendency to think, mistakenly, that human beings have nothing in common with other animals. ©2002 Prentice Hall ©2002 Prentice Hall
