psychometric tests |
tests of different aspects of an individuals intellectual performance |
|
|
intellegence tests |
measure general factors that predict success in school |
|
|
intellegence tests typically measure |
-digit span -vocab -analogical reasoning - Spatial Judgement - Arithmetic |
|
|
Intellegence quotient; a measure of general intellectual performance |
iQ= 100 x mental age/chronological age |
|
|
current definition of IQ |
IQ= 100 + 15 x (score- mean of age group)/standard deviation |
|
|
IQ have a |
mean of 100 SD of 15 |
|
|
Bouchard, 1983 suggests |
identical twins raised apart ten to have IQ's that are more simiar to each other than do non-idenetical twins raised together |
|
|
speaman 1904 argues |
that there is one general intelligence factor. |
|
|
Cattell 1963 proposed |
that we have 2 types of intellegence; crystallized intellegence and Fluid intellegence |
|
|
Crystallized intelligence |
depends on acquired knowledge (what you learn) |
|
|
Fluid intellegence |
reflects the ability to reason and problem solve |
|
|
Factor analysis |
A statistical method that tried to find a set of factors that will account for performance across a range of tests |
|
|
Goldberg et al 1977 |
participants performed 3 types of word judgement tasks; identify judgement (bear/bear), Sound judgement (bear/bare), meaning judgement (bear/lion) |
|
|
verbal ability |
A major advantage of people who score high in psychometric tests of verbal ability is the speed with which they retrieve the meanings of words |
|
|
Daneman and Capenter 1980 |
verbal ability participants read or listened to a number of unrelated sentences. then were asked to recall the last word of each sentance (measuring the reading span or listening span). These span measures strongly correllate with performance on verbal ability tests |
|
|
people with high verbal ability are able to |
rapidly retrieve meanings of words and have large working memory for verbal information |
|
|
Spatial ability |
people with high spatial ability can process spatial information rapidly |
|
|
individual differences in reasoning, verbal, and spatial abilities may result from differences in |
rates of processesing, working memory |
