Most Famous theory

1. Thurston's Seven Factors Theory
Presented by Rustam

2. Intelligence
• “Intelligence, considered as a mental trait, is
the capacity to make impulses focal at their
early, unfinished stage of formation”.
• Intelligence is therefore the capacity for
abstraction, which is an inhibitory process

4. Louis Leon Thurston 1887-1955
• U.S. pioneer in the fields of
psychometrics
• He conceived the approach to
measurement
• law of comparative judgment,
• well known for his
contributions to factor
analysis.
• Proposed Seven Factors Theory

5. Thurston's Seven Factors Theory
• It is one of the leading exponent of multiple
theory.
• Thurston's identified seven factors of
Intelligence.
• Using his new approach to factor analysis,
• Thurstone found that intelligent behavior does
not arise from a general factor,
• but rather emerges from seven independent
factors that he called primary abilities

7. Thurston's 7 Abilities
Verbal comprehension: Grasping meaning of words, concepts and ideas.
Numerical Abilities: Speed and accuracy in numerical and computational skills.
Spatial Relations: Visualizing patterns and forms.
Perceptual Speed: Speed and Perceiving details.
Word Fluency: Using words fluently and flexibly.
Memory: Accuracy in recalling information.
Inductive Reasoning: Deriving general rules from presented facts.
