9. Abstract Using a visual search methodology we investigated the effect of feared animal
stimuli on attention. Our results confirmed the important role of emotion on
attention. All participants detected fear-relevant stimuli (snakes and spiders)
faster than neutral (mushrooms) ones against a background of fruits. In addition,
spider fearful participants were sensitized specifically to detect their feared
stimulus (spiders), compared to their fear-relevant but non-feared (snakes) and
neutral stimuli. However, for participants fearful of snakes there was no
significant difference in detection latencies between the feared (snakes) and the
fear-relevant but non-feared animal stimuli (spiders). The results from the
attention task were mirrored in the emotional ratings, which showed that spider
fear was highly specific, whereas snake fear was associated with a more
generalized enhanced evaluation of all negative stimuli. (PsycINFO Database
