Abstract
Isarida, Fukasawa, & Isarida (2015) investigated odor-dependent recognition for short and long study-time conditions. The results were well accounted for by the encoding specificity. Noteworthy odor-dependent recognition was found in both of the study-time conditions, whereas place-dependent recognition was not found in the long study-time condition possibly suppressed by the outshining (Isarida, Isarida, & Sakai, 2012). This result might indicate that the cue strength of odor is stronger than that of place. The present study investigated whether odor-dependent recognition would be outshone by stronger item cues. Thus, we shortened the list length from 40 (Isarida et al., 2015) to 30. Neither short nor long study-time condition revealed odor-dependent effect with the shorter list. Furthermore, Cohen's d values of global environmental contexts, that is, odor, place, and background-music contexts, decreased as a function of Hit rate in DC condition (estimated strength of item strength).
