Boys aged 7-9 show better 3D mental rotation skills than girls, with higher spatial skills linked to improved math performance in boys. This highlights the importance of spatial processing in arithmetic achievement.
Area of Science:
- Cognitive Development
- Educational Psychology
- Neuroscience
Background:
- Spatial reasoning is crucial for mathematical abilities.
- Understanding sex differences in spatial skills can inform educational strategies.
- Previous research suggests potential differences in spatial abilities between boys and girls.
Purpose of the Study:
- To investigate sex differences in 3D mental rotation ability among schoolchildren aged 7-12 years.
- To examine the relationship between 3D mental rotation performance and arithmetic achievement in children.
- To introduce a new, dedicated task for assessing children's mental rotation capabilities.
Main Methods:
- Development and application of the "Mental Rotation Task - Children" (MRT-C).
- A large sample of 729 schoolchildren aged 7-12 years participated.
- Analysis of sex differences in MRT-C performance and correlation with arithmetic scores.
Main Results:
- A significant sex difference was observed in 7- to 9-year-olds, with boys outperforming girls on the MRT-C.
- Boys were overrepresented in higher performance quartiles, while girls were overrepresented in lower quartiles.
- Higher mental rotation performance correlated with better arithmetic achievement in boys, but not in girls.
Conclusions:
- Boys aged 7-9 demonstrate superior 3D mental rotation abilities compared to girls.
- Spatial processing skills are significantly linked to mathematical achievement, particularly in boys.
- Findings have implications for educational practices aimed at enhancing spatial and mathematical skills in children.

Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
