当在掩蔽模式的背景下呈现时，刺激的感知可能会受损。为了确定人脸加工的时间和性质，研究了不同面具对人脸辨别能力的影响。结果表明，掩蔽效应很强：掩蔽效应的大小取决于掩蔽目标与掩蔽目标的相似程度。对于非面罩（噪音、房屋），掩蔽是不存在的，对于杂乱和倒置的脸，掩蔽是适度的，而对于直立的脸，掩蔽是最强的，即使它们在大小、性别或视角上与目标不同。这表明掩蔽（可能是FFA）的纹状体外位置。减少，但显着的掩蔽孤立的面部部分（内部功能或头部形状）是一致的整体计算在面部感知。持续时间超过一个面具可以损害面部歧视（130毫秒）是显着长于先前假设的，是足够的迭代和反馈计算的一部分，面对处理。(c)2005爱思唯尔有限公司保留所有权利。
The perception of a stimulus can be impaired when presented in the context of a masking pattern. To determine the timing and the nature of face processing, the effect of various masks on the discriminability of faces was investigated. Results reveal a strong configural effect: the magnitude of masking depends on the similarity between mask and target. Masking is absent for non-face masks (noise, houses), modest for scrambled and inverted faces and strongest for upright faces, even when they differ in size, gender or viewpoint from the targets. This suggests an extra-striate location for the masking (possibly FFA). Reduced but significant masking for isolated face parts (internal features or head shape) is consistent with holistic computations in face perception. The duration over which a face mask can impair face discrimination (130 ms) is markedly longer than previously assumed and is sufficient for iterative and feedback computations to be part of face processing.
