Paper Co-Authored by Prof. Yoshikawa Published in the Journal of Cognitive Psychology

A research paper by Lecturer Masato Nunoi and Prof. Sakiko Yoshikawa was published in the Journal of Cognitive Psychology, Vol. 28, Issue 6.
This study investigated if the depth of stimulus processing influenced preferences for novel objects, and how long the influence of processing levels persisted. Results showed that stimuli that were processed more deeply were preferred over those that were processed more shallowly. It also suggested preferences persisted longer for information that was processed at a deeper level.

The purpose of the current study was twofold. First, we investigated whether the type of stimulus processing (e.g. levels of processing) influenced preferences for novel objects. Second, we examined whether the influence of levels of processing on preferences was long lasting (e.g. longer than a day/week). Results showed that levels of processing affected preferences whereby more deeply processed stimuli were preferred over those that were shallowly processed. This effect was more robust for stimuli that were presented multiple times. Additionally, this levels of processing effect lasted for up to 6 weeks, suggesting stability in preferences for information that was more deeply processed. We discuss these results in terms of theories predicting the role of stimulus properties and exposure on the development of preferences.
