Summary
Males show advantages in arithmetical reasoning, spatial cognition, and computational fluency. These cognitive skills, particularly spatial abilities and computational fluency, mediate the observed male advantage in mathematical problem-solving.
Area of Science:
- Cognitive Psychology
- Educational Psychology
- Neuroscience
Background:
- Sex differences in arithmetical reasoning are well-documented.
- Previous research suggests potential links to spatial cognition and computational fluency.
Purpose of the Study:
- To investigate the mediating roles of spatial cognition and computational fluency in male advantages in arithmetical reasoning.
- To test competing hypotheses explaining sex differences in mathematical problem-solving.
Main Methods:
- Administered arithmetical computation, arithmetical reasoning, IQ, and spatial cognition tests to 113 males and 123 females.
- Employed structural equation modeling to analyze relationships between variables.
Main Results:
- No significant sex difference was found in IQ scores.
- Males scored significantly higher in arithmetical computations, arithmetical reasoning, and spatial cognition.
- Individual differences in arithmetical reasoning were associated with IQ, spatial abilities, and computational fluency.
Conclusions:
- The male advantage in arithmetical reasoning is significantly mediated by advantages in computational fluency and spatial cognition.
- These findings provide insight into the cognitive underpinnings of sex differences in mathematical abilities.
