What is interactionism?
Heredity and the environment interact to influence one’s intellect
What is Wechsler’s definition of intelligence?
“The aggregate or global capacity of the individual to act purposefully, think rationally, and deal effectively with his environment”
What were Galton’s beliefs about intelligence?
Emphasis on the heredity of intelligence & individual differences
What were Binet’s beliefs about intelligence?
Intelligence is a relative contribution of abilities
Test scores are a measure of performance, not necessarily “true” intelligence
What is the Binet-Simon intelligence test designed for?
To identify “gifted” children and children in need of special educational assistance
Introduced the concept of a “mental age”
What were Terman’s contributions to intelligence testing?
Revised the Binet-Simon scale to what is now known as the Stanford-Binet test
Created a ratio IQ of mental age over chronological age x 100
How did the Stanford-Binet test improve upon the Binet-Simon test? (4 things)
Improved the norms, demonstrated reliability and validity, can be used adaptively, and can create a profile analysis of performance
What were Wechsler’s beliefs about intelligence and contributions to intelligence testing?
Intelligence is not the mere sum of abilities, so it’s important to measure several aspects
Developed an intelligence test that included non-verbal tasks
What were Piaget’s contributions to intelligence testing?
The stages of cognitive development
What is factor analysis?
A group of statistical methods used to find underlying relationships between sets of variables or items
What are the various factor-analytic theories of intelligence?
Spearman, Guilford & Thurstone, Gardner, Horn & Cattell, Carroll
What was Charles Spearman’s theory about intelligence?
There exists a general intellectual ability factor (called “g”) and other specific, hierarchical factors (called “s”)
There is also an intermediate class of factors common to a group of activities, called group factors
How was Guilford & Thurstone’s theory of intelligence different than Spearman’s?
They opted to de-emphasize or eliminate any reference to “g”
How was Gardner’s theory of intelligence different than Spearman’s?
His theory contains seven different intelligences rather than one general factor “g”
How was Horn & Cattell’s theory of intelligence different than Spearman’s?
Their theory proposes the existence of two major types of cognitive abilities: crystallized intelligence and fluid intelligence
What are the differences between Crystallized Intelligence and Fluid Intelligence?
Crystallized: includes acquired skills and knowledge; requires some degree of exposure to education and culture; is relatively unaffected by aging and brain injury
Fluid: the ability to adapt to novel situations, independent of specific instruction; nonverbal; relatively culture-free; is more affected by aging and brain injury
How did Carroll add onto Horn & Cattell’s theory of intelligence?
He agreed that specific factors were important, but didn’t want to completely get rid of the idea of “g” like the others did
What is the CHC model?
Integrated the Cattell-Horn and Carroll models into one, which featured 10 broad abilities and over 70 narrow ones
Current versions have 5 broad categories and don’t include a general intelligence ability factor
What are Thorndike’s three clusters of ability? How did he define intelligence?
Social, concrete, and abstract intelligence
Defined general mental ability as the number of modifiable neural connections
How are information-processing theories of intelligence different from factor-analytic theories?
They focus on identifying specific mental processes (i.e. HOW information is processed as opposed to WHAT is processed)
What is the difference between Simultaneous processing and Successive processing?
Simultaneous = parallel or integration of info all at once
Successive = sequential or information is individually processes in a logical sequence
What is the PASS model?
Stands for planning, attention, simultaneous, successive
Relates to the strategy, receptivity, and type of information processing
What are the commonalities of intelligence testing? (8 things)
How do ceiling and floor effects apply to intelligence testing? What is a basal level?
Floor = lowest level ability that can be tested
Ceiling = highest level ability that can be tested
Basal level = baseline level requirement to continue testing
