本研究探讨了性别差异的正确反应率和反应时间的任务，涉及左或右箭头选择和另一个涉及的手的心理旋转的转换。我们招募了15名健康的右撇子男性（年龄24.5 ± 6.4）和15名健康的右撇子女性（年龄21.3 ± 4.9）。在这些任务中，我们使用了左右箭头的图片和32张手的图片（左，右，手掌和背部），这些图片被放置在cons中（每个都在45度，从0度到315度）。手和箭头图片交替出现，并随机显示。参与者尽可能快地决定每张照片是左边还是右边。为了比较手的心理旋转转换所需的时间，我们从每个参与者的左手和右手图片中减去平均箭头反应时间。对于箭头或手的图片，男性和女性之间或左右之间的正确反应率没有显着差异。无论性别，左箭头图片的反应时间长于右箭头图片。对于男性和女性来说，手部图片的反应时间最长，因为旋转角度的图片最难与参与者的手对齐。虽然男性对左手和右手图片的反应没有差异，但女性对左手图片的反应比右手图片更长，也比男性的反应更长。这些结果表明，男性和女性主要是执行手的心理旋转任务与内隐运动想象。另一方面，在性能的性别差异可能是由不同的平衡与其他策略，如视觉图像，认知，神经生理和形态的差异。
This study explored gender differences in correct response rates and response times on a task involving left or right arrow selection and another involving the transformation of mental rotation of the hand. We recruited 15 healthy, right-handed men (age 24.5 +/- 6.4) and 15 healthy, right-handed women (age 21.3 +/- 4.9). For the tasks, we used pictures of left and right arrows and 32 hand pictures (left and right, palm and back) placed in cons (each at 45 degrees from 0 degrees to 315 degrees). Hand and arrow pictures alternated and were shown at random. Participants decided as quickly as possible whether each picture was left or right. To compare the time taken for the transformation of mental rotation of the hand, we subtracted the average arrow response time from that for the left and right hand pictures for each participant. Correct response rates did not differ significantly between men and women or left and right for either arrow or hand pictures. Regardless of gender, the response time was longer for the left arrow picture than right arrow picture. The response time for the hand picture was longest for both men and women for pictures at rotation angles that were most difficult to align with participants' hands. While there was no difference between men's responses for left and right hand pictures, the responses of women were longer for left than right hand pictures and also than those of men. These findings suggest that both men and women mainly perform the hand mental rotation task with implicit motor imagery. On the other hand, the gender difference in performance might be explained by the difference in balance with other strategies, such as visual imagery, and by cognitive, neurophysiological, and morphological differences.
