The effects of exposure sequence and duration on mere exposure effect


This study investigated how exposure sequence and a delay influenced mere exposure effect. We used neutral random shapes and controlled exposure squence (heterogenous (spaced) and homogenous (unspaced)), exposure frequency (3, 6, and 9 times), and intervals between learning and judgment (5 min and 1 week).Fifty five participants were exposed to each stimulus, and 5 min and 1 week later, were asked to rate preference, familiarity, novelty, nostalgia, using a 5-point scale as well as recognition of old and new items. The result shows that, in judgments about preference, familiarity, and nostalgia, scores for the stimuli in homogenous exposure condition rose after 1 week, although scores in heterogenous exposure condition didn’t change with a delay. In homogenous and high frequent presentation, nostalgia occurred by an interval of one week, and that nostalgia raised stimuli’s preference and familiarity.
