简介
The phenomenon of an attentional bias has been found for threatening stimuli, such as snakes, when presented simultaneously with neutral stimuli. This priority attentional bias effect regarding snakes has been shown through reaction time- or response accuracy-based paradigms. Many studies suggested a preattentive attentional capture of threatening stimuli based on inferences from reaction time data, which might as well be caused by the same rather slow elaborated cognitive processing for threatening stimuli as for neutral stimuli, but more strong motor preparation for source of potential threat. To overcome this ambiguity in the outcomes from reaction time data, eye movements recording can be an alternative approach. The aim of the present study was to examine exogenous spatial attentional orienting when snakes were competing subliminally with neutral stimuli while presenting a video clip. In a free …
