The
detection of threatening social stimuli quickly and modifying our behaviors
according to the context is beneficial for avoiding social conflict. Our visual
system is, therefore, thought to have evolved to be more sensitive to
threatening faces than to other facial expressions. Angry faces are universally
treated as signals of potential threat. They are processed rapidly and
efficiently, and are particularly efficient in capturing attention. Thisphenomenon is defined as the anger superiority effect [ASE].
ASE has been
studied using a visual search paradigm in which participants searched for
discrepant angry or happy faces in a crowd of distractor faces. Several studies
have confirmed that ASE can be observed with schematic-faces as well. By using
schematic faces it is possible to eliminate many low-level perceptual
variations found in photographs of emotional expressions, and to better control
experiment variables. ASE has recently been tested in participants with Autism
Spectrum Disorders [ASD] using the same face-in-the-crowd paradigm in adults,
as well as children and adolescent. Read more>>>>>>>>>>>>>>
