chapter 10 Flashcards
Intelligence
is the ability to acquire knowledge, to think and reason effectively and to deal adaptively with the environment
Galton
- People had inherited mental constitutions that made them more fit for thinking than their less successful counter parts
- Relationship between biological variables and intelligence
- Skull size had a positive relationship with intelligence
Binet
- Mental test
- Mental abilities developed with age
- The rate at which people gain mental competence is a characteristic of the person and is fairly consistent over time
- Mental age- developed a standardised test in which the children will be interviewed and be given a mental age
Sterns intelligent quotient (IQ
was the ratio of mental age to chronological age, multiplied by 100: IQ = (mental age/chronological age) x 100
Terman
- Revised test became known as the Stanford – binet test
- Yields to a single IQ score
Eugentics
the idea that children with a lower IQ are less intelligent
Weschler
developed a test that measured verbal and non verbal intelligence
- WISC
- WAIS
- WPPSI
Psychometric
is the statistical study of psychological tests. Tries to find individual differences in performance
Factor analysis
reduces a large number of measures to a smaller number of clusters or factors with each cluster containing variables that correlate highly with one another but less highly with variables in other clusters
G factor:
Spearmen
- General intelligence
- Can be related to job performance and success
Crystallised intelligence:
Cattel and Horn
- Is the ability to apply previously acquired knowledge to current problems
- Depends on the ability to deal with novel problem-solving situations for which personal experience does not provide a solution
- Dependant on the long term memory
Fluid intelligence:
Cattel and Horn
- Defined as the ability to deal with novel problem social situations for which personal experience does not provide a solution
- Involves inductive reasoning and creative problem solving
- Dependant on the working memory
Carrolls three stratum model
stratum 3:
- is a g factor
- underlie the most mental activity
stratum 2:
- eight broad intellectual factors from left to right depending on how much they are influenced by the g factor
- involves basic cognitive functions such as memory and learning
stratum 1:
- involves 70 highly specific cognitive abilities that feed into the broader stratum 2 factors
cognitive process approaches:
- explore the specific information processing and cognitive processes that underlie intellectual ability
Sternberg
triachic theory of intelligence:
- addresses both the psychological processes involved in intelligent behaviour and the diverse forms that intelligence can take
