Chapter 6 Thinking and Intelligence

Copyright © 2012 Pearson Education, Inc. All rights reserved. Thinking is a cognitive process in which the brain uses information from the senses, emotions, and memory to create and manipulate mental representations, such as concepts, images, schemas, and scripts. What Are the Components of Thought?

Thinking Cognitive process in which the brain uses information from the senses, emotions, and memory to create and manipulate mental representations such as concepts, images, schemas, and scripts Result Reasoning, imagining, judging, deciding, problem solving, expertise, and creativity

Copyright © 2012 Pearson Education, Inc. All rights reserved. Concepts Mental groupings of similar objects, ideas, or experiences. Natural concepts represent objects and events from direct experience. Prototypes are the most representative examples of a conceptual category. Artificial concepts are defined by rules. We organize the bulk of our declarative memories into concept hierarchies.

Imagery and Cognitive Maps Visual imagery adds complexity and richness to our thinking. Thinking with sensory imagery can be useful in problem solving. Cognitive maps are a cognitive representation of a physical space.

Event-Related Potentials Brain waves shown on an EEG in response to stimulation MRI (Magnetic Resonance Imaging) Identifies brain regions that become active during various mental tasks

Frontal Lobe Control Frontal Lobe is particularly important for coordinating brain activity by: Keeping track of the episode (situation) Understanding the context (meaning) Responding to a specific stimulus The frontal lobe is also involved in intuition: that is, making judgments without consciously reasoning.

Schemas and Scripts Help you Know What to Expect Schema A cluster of related concepts that provides content and expectations about the features likely to be found when you encounter familiar people, situations, images, and ideas Script A cluster of knowledge about sequences of events and actions expected to occur in particular settings

Knowledge; expertise Aptitude (innate potentials) Personality characteristics independence, intense interest in a problem, willingness to restructure, preference for complexity, need for stimulating interaction

Defining Intelligence The mental capacity to acquire knowledge, reason, and solve problems effectively. Copyright © 2012 Pearson Education, Inc. All rights reserved.

How is Intelligence Measured? Intelligence testing has a history of controversy, but most psychologists now view intelligence as a normally distributed trait that can be measured by performance on a variety of tasks.

Copyright © 2012 Pearson Education, Inc. All rights reserved. Founding of the Intelligence Test In 1904, a new French law required all children to attend school. Alfred Binet and Theodore Simon Developed a test to identify students needing remedial help Measured current performance and not a measure of innate intelligence Emphasized training and opportunity could affect intelligence Constructed the test empirically

Sample Items from the First Binet-Simon Test Copyright © 2012 Pearson Education, Inc. All rights reserved.

How is Intelligence Measured? The Binet-Simon Test calculated a child’s mental age (MA) and compared it to his or her chronological age (CA). MA: average age at which individuals achieve a particular score CA: number of years since birth (age) The test determined that remedial help was needed when one’s MA was two years behind one’s CA.

Binet-Simon test in America: Lewis Terman, Stanford University Stanford-Binet test became a popular instrument in clinical psychology, psychiatry, and educational counseling. The Stanford-Binet Intelligence Scale is the most respected of the new American tests of intelligence. Now measures intelligence quotient (IQ) (Stern) IQ=(MA/CA)*100

Copyright © 2012 Pearson Education, Inc. All rights reserved. Calculating IQs “on the Curve” The original IQ calculation was abandoned in favor of standard scores based on the normal distribution. Normal Distribution Bell-shaped curve describing the spread of a characteristic throughout a population Normal Range Scores falling near the middle of a normal distribution

The Exceptional Child Mental Retardation Often conceived as representing the lowest 2 percent of the IQ range; the current view deemphasizes IQ scored and focuses on practical abilities Giftedness Often conceived as representing the upper 2 percent of the IQ range

African Concepts of Intelligence Not the same as Western assumptions In rural Kenya, children with the greatest practical intelligence skills scored lower on traditional IQ tests. In Buganda, intelligence is associated with slow and thoughtful responses. In Niger, intelligence is a combination of social skills and good memory.

Copyright © 2012 Pearson Education, Inc. All rights reserved. How Do Psychologists Explain IQ Differences among Groups? Hereditarian arguments maintain that intelligence is substantially influence by genetics. Environmental approaches argue that intelligence can be dramatically shaped by influences such as: Health Economics Education

Research has also shown that racial and class differences in IQ scores can be eliminated by environmental changes. Adoption Studies Social Class Head Start
