Intelligence
The ability to direct one’s thinking, adapt to one’s circumstances, and learn from one’s experience
Williams syndrome
Impairs people’s cognitive abilities such as counting, tying shoes but they usually have a great gift for literature and music.
What did Binet and Simon do?
Came up with a test to find the child’s “natural intelligence”
William stern
Thought the best way to determine if a child is developing a normally was to examine the ratio of a child’s mental age to the child’s physical age
Ratio IQ
Statistic obtained by dividing a person’s mental age by a person’s physical age and multiplying it by 100
Deviation IQ
Statistic obtained by dividing a person’s test score by the average test score of people in the same age group and then multiplying the quotient by 100
What is the correlation between IQ and academic performance?
Roughly .5
What can intelligence test scores predict?
Scholastic performance, job performance, health, and wealth
Factor analysis
Statistical technique that explains a large number of correlations in terms of small number of underlying factors.
Two- factor theory of intelligence
Suggested that every task requires a combination of a general ability (g) and skills that are specific to the task (s)
Primary mental abilities
Perceptual ability, verbal ability, and numerical ability (thurstone)
Confirmatory factor analysis
Hierarchy scheme:
General factor
Group factor
Specific factors
Eight independent middle level abilities
Memory and learning Visual perception Auditory perception Retrieval ability Cognitive speediness Processing speed Crystallized intelligence Fluid intelligence
Fluid intelligence
Ability to see abstracted relationships and draw logical inferences
Crystallized intelligence
Ability to retain and use knowledge that was acquired through experience
Theory based approach (Robert sternberg)
Analytic intelligence
Practical intelligence
Creative intelligence
Analytic intelligence
Ability to identify and define problems and to find strategies for solving them
Practical intelligence
Ability to apply and implement the solutions in everyday settings
Creative intelligence
Ability to generate solutions that other people do not
Emotional intelligence
Ability to reason about emotions and use emotions to enhance reasoning
Sir Francis Galton
Studied the physical and psychological traits that appeared to run in the families. (Book: hereditary genius concluded that intelligence was largely inherited)
Heritability coefficient (h^2)
Statistic that describes the proportion of the difference between people’s scores that be explained by difference in their genes
Shared environment
Those environmental factors that are experienced by all relevant members of a household
Non shared environment
Those environmental factors that are not experienced by all relevant members of a household
Flynn effect:
Generations are getting smarter
What effects IQ?
Socioeconomic status
More education
Genes and environment
What is the average IQ?
Between 85-115
Cognitive enhancers
Drugs that produce improvements in the psychological processes that underlie behavior (adderall)
Henry Goddard
Was one of the first to measure intelligence, discriminatorily toward Ellis island immigrants
Alfred Binet and Theodore Simon
Developed the first intelligence test to identify children who needed remedial education
William stern
Coined “mental age”
Lewis terman
Developed IQ test
Most widely used intelligence tests today
Stanford Binet and wechsler adult intelligence scale
Charles spearman
See out to discover if there was a hierarchy of abilities, and found correlations among many cognitive tasks
