Deficits in facial affect recognition (FAR) are often reported in autism spectrum disorder (ASD) due to inappropriate visual search strategies. It is unclear, however, whether or not deficits in subliminal FAR are still present in autism when visual focus is controlled. Thirteen persons with ASD and 13 healthy participants took part in this experiment. Supraliminal FAR was assessed using a standardized, computer-aided test. Subliminal FAR was obtained by an emotional face priming paradigm. By using an eye-tracking technique, it was assured that the initial visual focus was on the eyes of the prime. Persons with ASD showed worse FAR in supraliminal face recognition. Although controlled for initial gaze direction, participants also showed reduced negative face priming. These data confirm that FAR is disturbed already on a pre-attentive level in autism.
由于不适当的视觉搜索策略，自闭症谱系障碍（ASD）患者常被报道存在面部表情识别（FAR）缺陷。然而，当视觉焦点得到控制时，自闭症患者是否仍存在阈下FAR缺陷尚不清楚。13名自闭症患者和13名健康参与者参与了本实验。使用标准化的计算机辅助测试评估阈上FAR。通过情绪面孔启动范式获得阈下FAR。通过使用眼动追踪技术，确保初始视觉焦点在启动刺激的眼睛上。自闭症患者在阈上面部识别中表现出更差的FAR。尽管控制了初始注视方向，但参与者的负面面孔启动也有所减少。这些数据证实，在自闭症中，FAR在注意前水平就已受到干扰。
