摘要: There is increasing evidence that spiders are not feared because of harmful outcome expectancies but disgust and contamination-relevant expectancies. This study investigated the relative strength contamination- harm-relevant UCS covariation bias in spider phobia. High (n=25) low (n=24) fearful individuals saw a series slides comprising spiders, pitbulls, maggots, rabbits. Slides were randomly paired with either (electrical shock), contamination-related (drinking distasting fluid), or nothing. Spider displayed expectancy associated whereas controls bias. was no for (differential) postexperimental bias; thus biased robust against refutation. The present findings add to contamination ideation critically involved
