据报道，对不熟悉面孔的性别和年龄的感知在视网膜位置上有特异性地变化，例如，同一张雌雄同体的面孔可能在一个位置看起来是男性，但在另一个位置看起来是女性。在这里，我们测试空间异质性的识别个人熟悉的面孔在人类参与者的身份。我们发现，与高熟悉面孔相比，低熟悉面孔在参与者中是稳定的，并且在不同地点之间变化更大。这些数据表明，就像面部性别和年龄一样，面部身份在一定程度上是由监测有限空间区域的独立神经元群体处理的，并且在这些不同位置对同一张脸的识别反应不同。此外，重复和不同的社会互动似乎会导致这些独立的人脸识别神经元的调整，因此同一张熟悉的脸最终更有可能在相隔很远的视野位置引起相同的识别反应。我们提供了一个机械的帐户，这种减少retinotopic偏见的基础上的计算模拟。
The perception of gender and age of unfamiliar faces is reported to vary idiosyncratically across retinal locations such that, for example, the same androgynous face may appear to be male at one location but female at another. Here, we test spatial heterogeneity for the recognition of the identity of personally familiar faces in human participants. We found idiosyncratic biases that were stable within participants and that varied more across locations for low as compared to high familiar faces. These data suggest that like face gender and age, face identity is processed, in part, by independent populations of neurons monitoring restricted spatial regions and that the recognition responses vary for the same face across these different locations. Moreover, repeated and varied social interactions appear to lead to adjustments of these independent face recognition neurons so that the same familiar face is eventually more likely to elicit the same recognition response across widely separated visual field locations. We provide a mechanistic account of this reduced retinotopic bias based on computational simulations.
