Intelligence & Academic Achievement (6) Flashcards
g
general intelligence - a single trait
influences all aspects, dissimilar intellectual tasks
crystalized intelligence
factual knowledge, increases with age
fluid intelligence
ability to problem solve and think on the spot, peaks at 20 and decreases (PFC activity)
primary mental abilities (thurstone)
7 intellectual areas
word fluency, verbal meaning, reasoning, spatial visualization, numbers, memory, perceptual speed
Carroll’s three stratum theory of intelligence
interconnected process involving levels
where g influences basic abilities which influence specific processes
Weschsler intelligence test for children (WISC)
6yrs+
verbal section tests crystallized intelligence
performance section tests fluid intelligence (spatial & perceptual abilities)
IQ
Intelligence Quotient
based on a normal distribution of scores (mean 100)
Intelligence stability
IQ tests correlate strongly when close in age
scores are not constant over time
stability increases when child believes performance is valuable, parents are interested in their success
How does nature influence intelligence?
Genetics
Genotype-environment interaction
(passive, evocative, active)
Gender
How does environment influence intelligence?
Family (HOME scores) School - more school = higher IQ Society, poverty, healthcare, diet Cultural - subject matter, testing SES correlated with high and low IQ scores
HOME scores influence how well children do academically
- emotional and verbal responsivity of mother
- avoidance of restrictions and punishment
- organization of physical and temporal environment
- provisions of appropriate play material
- maternal involvement with child
- opportunities for variety of daily stimulation
Flynn effect
steady rise on average IQ’s over the past 80 years
How do risk factors affect IQ?
Many, not one risk factor predicts lower IQ
changes in risk factors over time predict IQ changes
differences in age is not a protective factor
Gardner’s theory
multiple intelligence theory (at least 8) linguistic logical-mathematical spatial musical naturalistic bodily-kinesthetic intrapersonal interpersonal
Sternberg’s theory
theory of successful intelligence - ability to achieve success
Analytic
Practical
Creative
