在猴子和人类受试者中，研究了感知正面眼睛注视的准确性，使用了一个人脸的成对照片上的强迫选择检测任务。 猴子很容易学会这项任务，但在双侧去除上级颞沟（STS）的银行和地板后，他们未能有效地执行任务。 该结果与基于清醒的行为猴子中的单细胞记录的结论一致[PERRET et al.，Physiological Aspects of Clinical Neuro-ophthalmology，Chapman & Hall，伦敦，1988]，颞叶的这个区域对于编码关于面对的动物的眼睛注视的信息是重要的。 在一项任务中，人类受试者被给予相同的刺激，他们被要求检测“直视你的脸”。“人类的表现对从正面凝视位置的角度偏差的程度很敏感，在0度的小角度偏差时最差。 这也是真实的猴子观看这些刺激，手术前和手术后。与正常对照组相比，两个人类prosopagnosics在这项任务中受损。 然而，两名患者的损害程度不同。 这些发现与早期的报道（包括那些右半球损伤而无前失认症的患者）、直立和倒置面部照片的正常表现以及面部处理中独立子系统的概念有关。
Accuracy at perceiving frontal eye gaze was studied in monkeys and human subjects using a forced-choice detection task on paired photographs of a single human face. Monkeys learned the task readily, but after bilateral removal of the banks and floor of the superior temporal sulcus (STS) they failed to perform the task efficiently. This result is consistent with the conclusion, based on recordings from single cells in awake, behaving monkeys [PERRET et al., Physioloigical Aspects of Clinical Neuro-ophthalmology, Chapman & Hall, London, 1988] that this region of the temporal lobe is important for coding information about eye-gaze of a confronting animal. Human subjects were given identical stimuli in a task where they were asked to detect "the face that is looking straight at you." Human performance is sensitive to the degree of angular deviation from the frontal gaze position, being poorest at small angular deviations from 0-degrees. This was also true of monkey viewing these stimuli, pre- and post-operatively.Compared with normal controls, two human prosopagnosics were impaired at this task. However the extent of impairment was different in the two patients. These findings are related to earlier reports (including those for patients with right-hemisphere damage without prospagnosia), to normal performance with upright and inverted face photographs, and to notions of independent subsystems in face processing.
