Spatial Attention Effects of Disgusted and Fearful Faces
Effective processing of threat-related stimuli is of significant evolutionary advantage. Given the intricate relationship between attention and the neural processing of threat-related emotions, this study manipulated attention allocation and emotional categories of threat-related stimuli as independent factors and investigated the time course of spatial-attention-modulated processing of disgust...
متن کاملDifferential effects of object-based attention on evoked potentials to fearful and disgusted faces.
Event-related potentials (ERPs) were used to investigate the role of attention on the processing of facial expressions of fear and disgust. Stimuli consisted of overlapping pictures of a face and a house. Participants had to monitor repetitions of faces or houses, in separate blocks of trials, so that object-based attention was manipulated while spatial attention was kept constant. Faces varied...
متن کاملMasked fearful faces modulate the orienting of covert spatial attention.
Dot probe studies indicate that masked fearful faces modulate spatial attention. However, without a baseline to compare congruent and incongruent reaction times, it is unclear which aspect(s) of attention (orienting or disengagement) is affected. Additionally, backward masking studies commonly use a neutral face as the mask stimulus. This method results in greater perceptual inconsistencies for...
متن کاملMeasuring the emotion-specificity of rapid stimulus-driven attraction of attention to fearful faces: evidence from emotion categorization and a comparison with disgusted faces.
In the current study, we tested whether a fear advantage-rapid attraction of attention to fearful faces that is more stimulus-driven than to neutral faces-is emotion specific. We used a cueing task with face cues preceding targets. Cues were non-predictive of the target locations. In two experiments, we found enhanced cueing of saccades towards the targets with fearful face cues than with neutr...
متن کاملSpatial attention-related modulation of the N170 by backward masked fearful faces.
Facial expressions are a basic form of non-verbal communication that convey important social information to others. The relevancy of this information is highlighted by findings that backward masked facial expressions facilitate spatial attention. This attention effect appears to be mediated through a neural network consisting of the amygdala, anterior cingulate, and visual cortex. However, a di...
