Similarity judgements were made about pairs of shapes explored haptically with the hands moving in the same (congruent), or opposite direction. Scanning shapes using an opposite manual direction was slower and less accurate. These results enabled stimulus selection for a further experiment that examined laterality effects in the haptic modality. Pairs of shapes were explored and the presence/absence of a target shape indicated using a pedal switch. Males showed a right hand disadvantage, whereas females were equally accurate at recognising target shapes with either hand, and were equivalent to males' left hand recognition accuracy. Direction of hand movements (congruent vs opposite) and target type also interacted with sex. These interactions and the 1-2 sec longer decision time by females suggest sex differences in the use of cognitive strategies rather than in hemispheric specialization of function.
对通过双手以相同（一致）或相反方向进行触觉探索的形状对进行相似性判断。使用相反的手动方向扫描形状速度较慢且准确性较低。这些结果为进一步的实验选择了刺激，该实验研究了触觉模态中的偏侧性效应。探索形状对，并使用踏板开关指示目标形状的存在/不存在。男性表现出右手劣势，而女性用任何一只手识别目标形状的准确性相同，并且与男性左手的识别准确性相当。手部运动方向（一致与相反）和目标类型也与性别相互作用。这些相互作用以及女性长1 - 2秒的决策时间表明，在认知策略的使用上存在性别差异，而不是在功能的半球特化上。
