Experiments investigating the effects of age and time of testing on implicit memory for distractors were executed with Japanese older and young adults from cross-cultural perspective with a modification of a Rowe, Valderrama, Hasher, and Leanartowicz (2006) procedure. Participants were required to make same or different judgments on line drawings superimposed with irrelevant Kanji characters, and then memory for distracters was tested with a Kanji perceptual identification test. Against expects according to Rowe et al. (2006), and supporting a prior research (Asano, Harada, Suto, Rowe, & Hasher, 2009) used Hiragana words as distractors, results showed that only young adults showed priming for the distractors, without any effects of time of testing. To explain these differences between studies, some hypothesis about cultural or linguistic differences between North Americans and Japanese as East Asians in cognitive processing styles will be discussed.
