Prior research has demonstrated robust sex and sexual orientation-related differences in object location memory in humans. Here we show that this sexual variation may depend on the spatial position of target objects and the task-specific nature of the spatial array. We tested the recovery of object locations in three object arrays (object exchanges, object shifts, and novel objects) relative to veridical center (left compared to right side of the arrays) in a sample of 35 heterosexual men, 35 heterosexual women, and 35 homosexual men. Relative to heterosexual men, heterosexual women showed better location recovery in the right side of the array during object exchanges and homosexual men performed better in the right side during novel objects. However, the difference between heterosexual and homosexual men disappeared after controlling for IQ. Heterosexual women and homosexual men did not differ significantly from each other in location change detection with respect to task or side of array. These data suggest that visual space biases in processing categorical spatial positions may enhance aspects of object location memory in heterosexual women.
先前的研究已经证明，在人类的物体位置记忆中存在着强大的性别和性取向相关差异。在这里，我们表明这种性别的差异可能取决于目标物体的空间位置和空间数组的特定任务性质。我们在 35 名异性恋男性、35 名异性恋女性和 35 名同性恋男性样本中测试了三个物体数组（物体交换、物体移位和新物体）相对于真实中心（与数组的左右两侧相比）的物体位置的恢复情况。与异性恋男性相比，异性恋女性在物体交换时在数组的右侧表现出更好的位置恢复能力，而同性恋男性在新物体时在右侧表现更好。然而，在控制智商后，异性恋男性和同性恋男性之间的差异消失了。在任务或数组的侧面上，异性恋女性和同性恋男性在位置变化检测方面没有显著差异。这些数据表明，在处理类别空间位置时，视觉空间偏见可能会增强异性恋女性的物体位置记忆的某些方面。
