Poor control of interference from negative content hampers the effectiveness of humour as a source of positive emotional experiences

Abstract

The brain-based ability to direct attention away from interfering negative information may co-determine to which degree one may benefit from humour as a source of positive emotional experiences. This should be particularly relevant when it comes to humour that implicates a target the joke makes fun of, which inherently entails rivalry between positive and negative emotional representations. One hundred healthy individuals completed a pictorial negative affective priming task and a nonverbal humour processing task. In line with the notion that during the elaborative processing of malicious jokes, interference from negative emotional representations hampers the experience of amusement, participants took more time to judge their amusement evoked by malicious compared to benign jokes. Lesser ability to distract attention from interfering negative emotional representations was associated with slower judgements of amusement following the processing of malicious jokes, as well as with lower amusement ratings. The time it took participants to comprehend the punch-lines was not affected, neither was the immediate, short-lived pleasure after having comprehended the humour, measured by characteristic transient cardiac activation. The findings suggest that the effective use of humour as a source of positive emotional experiences requires the ability to overcome the dark side of typical humour.
