AP PSYCHOLOGY

Detailed explanation-1: -In factor analysis, related variables are tested for correlation to each other, then the correlation of the related items are evaluated to find clusters or groups of the variables. Spearman tested how well people performed on various tasks relating to intelligence.

Detailed explanation-2: -The “g” factor is linked to the general ability, while the “s” factor is linked to the specific ability. The “g” factor reflects the capability of a person in doing the general mental ability tasks, and the “s” factor is responsible for recognizing the specific abilities of a person.

Detailed explanation-3: -To identify the underlying sources of these performance differences, Spearman devised factor analysis, a statistical technique that examines patterns of individual differences in test scores. He concluded that just two kinds of factors underlie all individual differences in test scores.

Detailed explanation-4: -Factor analysis is a multivariate technique designed to analyze correlations among many observed variables and to explore latent factors. Factor analysis was developed by the British psychologist Charles Spearman in the early 20th century as a technique for analyzing intelligence structures.

Detailed explanation-5: -This is known as Spearman’s two-factor theory.
