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.

Compensatory Effort

The effects of task-induced cognitive fatigue on performance, strategy, and P300 event-related potentials (ERPs) were examined. Fatigue was induced by task load with participants completing either 700 mental rotation trials with (high fatigue) or without (low fatigue) a secondary task to increase fatigue. No differences were found between groups when examining mental rotation task decision accuracy or strategy; however, the number of trials in which the participant’s total trial time was greater than twice their average was influenced by experimental manipulations designed to increase task difficulty. These ‘minibreaks’, referred to as blocking, may have served to regulate effort expenditure in order to preserve task performance. P300 peak amplitude differed between groups, with high blocking participants showing a reduced amplitude and more dispersed P300 topology compared to low blockers. These results provide compelling evidence that performance outcome may not be affected by task demands if a compensatory effort strategy is utilized.

Recent publications suggest that there is a developmental-based change of lateralization of brain activity during mental rotation from left to bilateral. But it is an open question whether this left hemisphere activation could also be observed with stimuli other than characters. To test this, behavioral data and event-related potentials (ERPs) were measured in 28 children, 28 juveniles, and 28 adults during a mental rotation task with animal drawings. The results showed that reaction times (RTs) and error rates decreased with the increasing age of the participants. Furthermore, RTs and error rates increased with increasing angular disparity. An unlateralized ERP amplitude modulation at parietal electrodes as a function of angular disparity was present in all age groups. These results contrast former studies revealing a left lateralization in children when characters were used as stimuli for mental rotation. Left hemisphere activation is therefore not a general developmental trend; rather, it is suggested that it might be a correlate of written language acquisition.
