Rapid orienting toward face-like stimuli with gaze-relevant contrast information

摘要: Human faces under natural illumination, and human eyes in their unique morphology, include specific contrast polarity relations that face-detection mechanisms could capitalise on. Newborns have been shown to preferentially orient simple face-like patterns only when they contain face- or gaze-relevant contrast. We investigated whether adults show similar preferential orienting towards schematic stimuli, this effect depends on the of stimuli. In two experiments we demonstrate upright elicit faster eye movements adult humans than inverted ones, occurs if information whole stimulus region only. These results suggest primitive underlying bias influence modulate social cognition not just infants but as well.
