The limited capacity of face perception resources in the left cerebral hemisphere was examined using a sex categorization task. One study tested the hypothesis that sex categorization is impeded whenever feature extraction resources in the left hemisphere are simultaneously being utilized by another task. This hypothesis was tested by presenting prime faces for either 32 ms or 320 ms to either the left or right visual-field just before centrally presented target faces were categorized by sex. Results showed that sex categorization was slower after prime faces were presented for 32 ms in the right visual-field compared to the left visual-field. This difference was not found after the 320 ms prime length. The results are interpreted in the context of a neurocognitive model of social perception and suggest that efficient sex categorization depends, in part, on the availability of facial feature extraction resources in the left hemisphere.
利用性别分类任务对左脑半球面部感知资源的有限能力进行了研究。一项研究检验了这样一个假设：只要左半球的特征提取资源同时被另一项任务占用，性别分类就会受到阻碍。通过在中央呈现的目标面孔进行性别分类之前，向左或右视野呈现32毫秒或320毫秒的启动面孔来检验这一假设。结果表明，与左视野相比，在右视野呈现32毫秒的启动面孔后，性别分类更慢。在启动面孔长度为320毫秒后未发现这种差异。研究结果在社会认知的神经认知模型背景下进行了解释，并表明有效的性别分类部分取决于左半球面部特征提取资源的可用性。
