Differences between Spearman's two-factor theory and Thurstone's group - factor theory.
(i) Number of components :-
Spearman's two-factor theory is a combination of two components.
But Thurstone's psychic ability is a combination of seven primary or basic elements.
(ii) Material subject :-
The two components of Spearman's two factor theory are denoted by G (general ability) and S (specific ability).
But the components of Thurstone's group factor theory are – Memory or M, Numeracy or N, Perceptual ability or P, Spatial awareness or S, Rationality or R, Verbal ability or V, Language ability or W.
(iii) Central idea of Theory :-
Spearman's two-factor theory states that general and specific components are required to perform a task.
But according to Thurstone's multifactor theory, one or more of the seven primary elements are used together.
(iv) Limitation :-
In Spearman's two-factor theory, general elements are used in all tasks while specialized elements are used in specific tasks.
But in Thurstone's multifactor theory, the power or energy needed to perform all actions is limited to seven basic elements.
(v) Other names :-
Spearman's two-factor theory is also known as electric theory.
Thurstone's multifactor theory is known as primary mental theory.
(vi) Material Requirements :-
In Spearman's two-factor theory, the G component is required for all functions.
In Thurstone's theory of multifactor there is no one element that is required for all tasks.
(vii) Nature of Material :-
In the two-factor theory, particular elements can be either innate or acquired.
But in Thurstone's multifactor theory, all seven elements are fundamental and inherent.
