Summary
Research on the Progressive Matrices IQ test reveals that males aged 15-18 score higher than females. This study provides new data confirming males
Area of Science:
- Psychology
- Cognitive Science
Background:
- A debate exists regarding sex differences in scores on the Progressive Matrices test.
- Disagreement centers on whether the difference is negligible or favors males by over 2 IQ points from age 15.
Purpose of the Study:
- To investigate sex differences in Advanced Progressive Matrices scores among adolescents.
- To contribute data to the ongoing debate on gender disparities in cognitive abilities.
Main Methods:
- Analysis of sex differences in a standardization sample of the Advanced Progressive Matrices.
- Inclusion of participants aged 15 to 18 years from Hong Kong.
Main Results:
- Males scored an average of 1.6 raw score points higher than females.
- This translates to an estimated IQ advantage of 3.2 to 4.1 points for males.
- The findings align with the hypothesis of higher male scores in later adolescence.
Conclusions:
- The study confirms significantly higher average IQ scores for males on the Progressive Matrices in later adolescence.
- These results support the view that males outperform females on this test from age 15 onwards.
