Sex of human stimulus matters: female and male stimuli are processed differently in mental rotation tasks

ABSTRACT

The main goal of the present study was to assess whether the sex of a human stimulus affects mental rotation performance. The results are pretty straight-forward: Men show a better performance than women and also male stimuli result in a faster processing by both women and men compared to female stimuli. Furthermore, the advantage of egocentric transformations over object-based transformations disappeared for females in difficult tasks using female stimuli. This experiment gives a hint that women are affected to a greater extent from the sex of the presented stimuli compared to men. The underlying mechanisms need to be investigated in future research.
