Size does matter: women mentally rotate large objects faster than men

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human Factors

Background:

• Spatial reasoning is crucial for various STEM fields.
• Previous research suggests sex differences in spatial abilities, particularly mental rotation.
• The impact of display size and field of view on these differences is not well understood.

Purpose of the Study:

• To investigate sex differences in mental rotation task performance.
• To examine the influence of display size and field of view on spatial task performance.
• To explore potential strategy differences between males and females in spatial tasks.

Main Methods:

• Participants (males and females) completed a computerized mental rotation task using Shepard-Metzler-like cube assemblies.
• The task was performed on two display conditions: a standard laptop screen (36 cm) and a large display wall (584 cm).
• Response time and accuracy were measured for each participant and condition.

Main Results:

• No significant difference in response time between sexes on the standard display.
• Females exhibited faster response times than males on the large display.
• Males demonstrated significantly higher accuracy than females, irrespective of display size.
• No evidence of a speed-accuracy trade-off was observed for either sex or display condition.

Conclusions:

• Display size can influence sex-based performance differences in mental rotation tasks.
• Males may employ a holistic strategy, which is hindered by larger stimuli.
• Females might use a piecemeal strategy, less affected by display size, potentially explaining their faster performance on large displays.
• These findings suggest strategy differences mediate the observed sex and display size interactions in spatial cognition.
