Document Summary
Developed techniques to calculate correlations among multiple measures of mental abilities: factor analysis: statistical technique that examines correlations between variables to find clusters of related variables or factors, ex. Language ability: when reading, vocabulary tests, and verbal reasoning correlate highly together. Effects of g could be due to motivation. Can it predict everything about a person"s intelligence: super smart but socially awkward, good at math but sucks at art. Spearman didn"t believe g didn"t fully capture intelligence. Correlation for different items on intelligence test less than 1. 0 which means it"s not a perfect prediction. Idiosyncratic knowledge- helps you answer particular question or amount of attention available to focus on the question in that moment. Skill or ability level for a given task. No one really questions the s part of the theory. Together it formed his two- part theory that was composed of g and s. Examined scores of general intelligence tests using factor analysis and found 7 different clusters.
