Contextual positivity-familiarity effects are unaffected by known moderators of misattribution.

ABSTRACTThe positivity-familiarity effect refers to the phenomenon that positive affect increases the likelihood that people judge a stimulus as familiar. Drawing on the assumption that positivity-familiarity effects result from a common misattribution mechanism that is shared with conceptually similar effects (e.g. fluency-familiarity effects), we investigated whether positivity-familiarity effects are qualified by three known moderators of other misattribution phenomena: (a) conceptual similarity between affect-eliciting prime stimuli and focal target stimuli, (b) relative salience of affect-eliciting prime stimuli, and (c) explicit warnings about the effects of affect-eliciting prime stimuli on familiarity judgments of the targets. Counter to predictions, three experiments obtained robust positivity-familiarity effects that were unaffected by the hypothesised moderators. The findings pose a challenge for misattribution accounts of positivity-familiarity effects, but they are consistent with alternative accounts in terms of affective monitoring.
