AbstractMental rotation of 3D objects demonstrates one of the largest sex differences. We investigated sex and sex hormones-related differences in behaviour and event related potentials (ERP) using a modified Shepard and Metzler task composed of sequentially presented 3D figures in 29 men and 32 women. We demonstrated a significant increase in response time and decrease in both accuracy and positivity of the parietal ERP with increasing angular disparity between the figures. Higher angular disparity evoked an increase of global field power (GFP) from 270 to 460 ms and different activation topographies from 470 to 583 ms with lower parietal, but higher left frontal positivity. Flatter slopes in higher angular disparity condition suggest distinct strategies being implemented depending on the difficulty of the rotation. Men performed the task more accurately than women. Performance accuracy in women tended to be negatively related to estradiol while the response time tended to increase with increasing progesterone. There were no associations with testosterone. Women demonstrated higher GFP and an increased positivity over the parietal scalp area, while men showed higher activation in the left frontal cortex. Together these findings indicate dynamic angular disparity- and sex-related differences in brain activity during mental rotation of 3D figures.

Recognition Efficiency

Women and men process emotion stimuli in different ways. Few of the previous researchers who have examined how emotion recognition differs between the sexes, looked at sex differences in emotion prediction. Thus, I investigated women's and men's perceptions of emotional faces in predictable and unpredictable conditions. Results showed that behaviorally, women's response accuracy was higher than men's. In contrast, neurally, men had greater P1 amplitudes for happy faces compared with angry faces in right hemisphere electrodes, suggesting that men have a perceptual bias toward happy faces. Further, women exhibited larger N170 amplitudes for predictable versus unpredictable angry faces in right hemisphere electrodes. This may reflect enhanced sensitivity to detecting anger. Finally, there was a significant positive correlation between behavioral and N170 predictability effects. This result may indicate that emotion prediction enhances neural responses while improving recognition efficiency at the behavioral level. In this respect, the electrophysiological results and behavioral data were consistent.
