Correlation of Cognitive Ability Scores

A rough guide to the correlations between scores in four domains: spatial reasoning, pattern recognition, logical reasoning, and classification. The relationship with the g factor, visualized.

In brief: The four domains, spatial reasoning, pattern recognition, logical reasoning, and classification, show moderate positive correlations of roughly 0.5 to 0.6 with one another. Behind this lies a general intelligence factor (g) shared across the domains. The figures in this table are illustrative values based on established findings.

Spatial ReasoningPattern RecognitionLogical ReasoningClassification
Spatial Reasoning1.000.580.550.52
Pattern Recognition0.581.000.600.50
Logical Reasoning0.550.601.000.54
Classification0.520.500.541.00

The moderate positive correlation among these domains is thought to reflect a shared general intelligence factor (the g factor) underlying them.

Frequently asked questions

Why do cognitive domains correlate with each other?
Because a general intelligence factor (g), involving reasoning and working memory, contributes to performance in every domain. The correlations stay moderate because each domain also draws on its own specific abilities.
How strong is a correlation of 0.5 to 0.6?
In psychology that is a moderate to fairly strong correlation. People who score high in one domain tend to score high in the others, but plenty of room remains for individual strengths and weaknesses.
Is this correlation table measured data?
No. The values are illustrative, based on established findings, not aggregated from actual test takers.
