6. 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

11. “A systematic review is a review of a clearly
formulated question that uses systematic and
explicit methods to identify, select, and critically
appraise relevant research, and to collect and
analyze data from the studies that are included in
the review”

Systematic Review and Meta-analysis
“Meta-analysis refers to the use of statistical
techniques in a systematic review to integrate the
results of included studies”
