原著論文Original ArticleOlder adults have a memory advantage for positively toned materials than negatively toned materials compared to younger adults, and this phenomenon is called "positivity effect." The present study examined how experimental design influences emotional memory. In this experiment, 20 younger adults (20.15 years old, SD= 1.01) and 25 older adults (69.08 years, SD= 5.68) were presented encoded words in a blocked list that contained positive, negative, and neutral materials, separately. After encoding, the participants completed a free recall word task. The recall performance on the negative list was highest in younger adults, but that on the positive list was highest in older adults. In this study, in addition to positivity effect, positive bias was also observed in older adults. Compared to previous research using a mixed list that contained positive, negative and neutral materials, the present results indicated a more apparent positivity effect. These results suggest that using a blocked list makes it easy to switch attention and clearly indicates a positive bias
