intelligence
the ability to learn from experience, solve problems, and use knowledge to adapt to new situations
general intelligence (g)
Spearman - underlies all mental abilities and is measured by every task on an intelligence test
factor analysis
statistical procedure that identifies clusters of related items (factors) on test; used to identify different dimensions of performance that underlie a total score
Thurstone
7 clusters of primary mental abilities (word fluency, verbal comprehension, spatial ability, perceptual speed, numerical ability, inductive reasoning, memory); scoring well in one generally scored well in others
Gardner’s multiple intelligences
8 relatively independent intelligences (linguistic, logical-mathematical, musical, spatial, bodily-kinesthetic, intrapersonal, interpersonal, naturalist, existential - possible 9th)
Savant syndrome
person otherwise limited in mental capacity has exceptional specific skill
Sternberg’s 3 intelligences (triarchic theory)
analytical, creative, practical
analytical intelligence
academic problem-solving - intelligence tests; well-defined problems have a single right answer
creative intelligence
innovate smarts; the ability to adapt to new situations and generate novel ideas
practical intelligence
every day tasks; may be poorly defined and have multiple solutions
successs
combination of talent and grit
grit
passion and perseverance in pursuit of long-term goals
social intelligence
Thorndike - understanding social situations and managing ourselves successfully
emotional intelligence
Thorndike - the ability to perceive, understand, manage, and use emotions
perceive emotions
recognize emotions and identify your own emotions
understand emotions
predict emotions and how they may change
manage emotions
know how to express emotions and help others manage their emotions
use emotions
facilitate adaptive/creative thinking
personal competence and recognition
self-awareness
personal competence and regulation
self-regulation
social competence and recognition
empathy/social awareness
social competence and regulation
relationship management
intelligence test
assesses individual’s mental aptitudes and compares them with those of others, using numerical scores
achievement test
designed to assess what a person has learned
aptitude test
designed to predict person’s future performance
aptitude
capacity to learn
Francis Galton
tried to measure “natural ability” and see if those with high ability would mate with one another - assessed “intellectual strengths” but no correlation; showed that individual scientists are affected by their own assumptions and attitudes
Alfred Binet and Theodore Simon
designed fair tests to minimize bias in education - made no assumptions about the cause and leaned toward an environmental explanation
mental age
level of performance typically associated with children of a certain chronological age
Lewis Terman
tried Binet’s test and expanded it (Stanford-Binet)
Stanford-Binet
widely used American revision of Binet’s original test
William Stern
proposed the idea of the intelligence quotient (IQ)
intelligence quotient (IQ)
originally the ratio of mental age to chronological age multiplied by 100; now assign a score that represents an individual’s performance relative to average performance
Wechsler Adult Intelligence Scale (WAIS) & Weschler Intelligence Scale for Children (WISC)
most widely used intelligence test - verbal and performance (nonverbal) subtests
standardization
defining uniform testing procedures and meaningful scores by comparison with the performance of a pretested group
normal curve
bell-shaped curve that describes the distribution of certain attributes
flynn effect
intelligence test performance has improved over the years
reliability
the extent to which a test yields consistent results
split-half
agreement of odd-question scores and even-question scores
test-retest reliability
retest people with the same test to ensure reliability
validity
the extent to which a test samples the behavior of interest (criterion)
content validity
how well a test measures the information it is intended to measure
construct validity
how well a test measures a concept
criterion validity
how well a test correlates with an established outside measure
predictive validity
the success with which a test predicts the behavior it is designed to predict - assessed by computing correlation between test scores and criterion behavior
cross-sectional study
compares people of different ages at the same point in time
longitudinal study
follows and retests the same people over time
cohort
a group of people with a common characteristic
crystallized intelligence
accumulated knowledge and verbal skills - tends to increase with age
fluid intelligence
ability to reason speedily and abstractly - tends to decrease with age
intellectual disability
condition of limited mental ability - intelligence scores of 70 or below and difficulty adapting to the demands of life
Down Syndrome
mild to severe intellectual disability and associated physical disorders - caused by an extra copy of chromosome 21
heritability
the proportion of variation among individuals in a group that can be attributed to genes
polygenic
involving many genes
Carol Dweck
believing intelligence is changeable fosters a growth mindset
mindset
mental attitude or attitude towards your mentality/capabilities
growth mindset
believes that intelligence can be changed
fixed mindset
believes that one has a certain amount of intelligence that can’t be changed
Steven Pinker
biology affects gender differences in life priorities, in risk-taking, and in math reasoning and spatial abilities
3 parts of the debate over racial differences
genetically disposed racial differences, socially influenced racial differences, tests are inappropriate/biased
bias
whether a test predicts future behavior only for some groups of test-takers (detects not only innate differences in intelligence but also performance differences caused by cultural experiences)
steretype threat
self-confirming concern that one will be evaluated based on a negative stereotype
standardized tests
tests with items that have been piloted on a population similar to those who are meant to take the test and whose achievement norms have been established
