Participants judged which of two vibrotactile stimuli presented to the index fingers or thumbs occurred first. Past research has shown performance on this vibrotactile temporal order judgment (TOJ) task was more accurate when the hands were kept in their respective hemispaces, compared to when the hands were crossed over the midline. We examined the role of vision in this crossed-hands TOJ deficit by implementing three different visual conditions: eyes open with the lights on, eyes open with the lights off, and eyes closed with the lights off. No differences were seen. However, upon closer examination of the data, a significant effect of gender was found, such that male participants showed a smaller crossed-hands deficit than female participants. This overall difference was seen in the context of large individual differences.
