Attentional Biases In Processing Emotional Facial Expressions: Effects Of State Anxiety, Trait Anxiety And Awareness, Mark Edwards
Attentional Biases In Processing Emotional Facial Expressions: Effects Of State Anxiety, Trait Anxiety And Awareness, Mark Edwards
Mark Edwards
The effect of state anxiety and trait anxiety on selective attention for threatening, neutral and happy schematic faces was investigated. A student sample was assigned to high trait anxious (HTA) or low trait anxious (LTA) groups using questionnaire scores and state anxiety was manipulated through the threat of electric shock. Stimulus materials were presented both outside (using a backward masking procedure) and within awareness. A novel version of a probe classification task was developed to assess performance when distracting information and the central task were spatially separated. For the masked trials, the LTA group were slower to identify the status …

It has long been argued that face processing requires disproportionate reliance on holistic or configural processing, relative to that required for non-face object recognition, and that a disruption of such holistic processing may be causally implicated in prosopagnosia. Previously, we demonstrated that individuals with congenital prosopagnosia (CP) did not show the normal face inversion effect (better performance for upright compared to inverted faces) and evinced a local (rather than the normal global) bias in a compound letter global/local (GL) task, supporting the claim of disrupted holistic processing in prosopagnosia. Here, we investigate further the nature of holistic processing impairments in …

A useful framework for understanding the mental representation of facial identity is face-space (Valentine, 1991), a multi-dimensional cognitive map in which individual faces are coded relative to the average of previously encountered faces, and in which the distance among faces represents their perceived similarity. We examined whether individuals with prosopagnosia, a disorder characterized by an inability to recognize familiar faces despite normal visual acuity and intellectual abilities, evince behavior consistent with this underlying representational schema. To do so, we compared the performance of 6 individuals with congenital prosopagnosia (CP), with a group of age- and gender-matched control participants …
