Abstract:

In a visual search task, displays of four schematic faces (angry, sad, happy, or neutral) were presented. Participants decided whether the faces were all the same or whether one was different. A discrepant angry face in a context of three neutral faces was detected faster than other faces. This occurred in the absence of a higher probability of first fixation on the angry face. Moreover, angry faces were more accurately detected even when presented parafoveally. These results are not consistent with the hypothesis that angry faces are detected faster because they are looked at earlier. In contrast, angry faces were looked at less than other faces during the search process and were more accurately detected than other faces when the display duration was reduced to 150 ms. These results support the processing efficiency hypothesis, according to which fewer attentional resources are needed to identify angry faces, which would account for their speeded detection time. In addition, parafoveal analysis of the angry faces may start preattentively, which would account for the fewer and shorter fixations that they need later, when they come under the focus of attention.
