摘要: Uncertainty is an omnipresent force in peoples’ lives that has been shown to amplify the negative impact of aversive events. This amplified aversiveness, together with attitudes individuals can have toward uncertainty, suggests a cue indicating uncertainty about future events might be associated biased expectancies outcomes or contingency estimates, similar biases observed for traditional fear-relevant cues, such as snakes spiders. Participants this study saw three different cues: one indicated certainty picture would follow, neutral and whether follow. Online self-report data revealed negatively aversion following uncertain cues. The degree online expectancy bias predicted subjects’ at conclusion experiment, relationship between cues pictures. Aversive pictures (relative those certain cue) were accompanied by increased skin conductance responses self-reported mood. These findings heightened warrant extensions research anxiety disorders, given evidence intolerance anticipatory dysfunction pathology disorders.
