概要: 金沢大学人間社会研究域人間科学系<br />We confirmed an increase in false recognition for visual short-term memory of the elderly using a … recognition task, which was affected by the test method. Old/new judgments and a forced-choice task were used as the recognition tasks and the hit rate, false alarm rate, and d' for each task were compared across age groups. The results indicated that there were significant differences in the hit rate, false alarm rate and d' across age groups for both recognition tasks. However, in the forced-choice task, where judgments could depend on familiarity, the false alarm rate among the elderly group decreased and differences in d' across age groups became smaller. The elderly could input sight information, but had more difficulty to input the geometric details. We concluded that the false alarm rate for short term visual memory increases in the elderly, but it decreases when recognition judgments can be made based on familiarity.<br />出版者許可を得て登録 続きを見る

概要: 金沢大学人間社会研究域人間科学系<br />Age-related changes in processing and retention in visual working memory were examined using visua … l stimuli that do not allow for verbal-name coding. Participants ranged in age from their 20s to 70s, and data was analyzed using the cross-sectional cohort method. The N-back task was used, and results from the 0-back task (recognition of the last of the continuously presented stimuli) and the 1-back task (recognition of the penultimate stimulus) were compared. The results showed a sudden decrease in performance on the 0-back task for participants in their 60s, and a relatively linear decrease on the 1-back task from the 30s. These results suggest that aging-related changes in visual working memory reflect a decrease in processing speed. They also suggests that the functions of “simple retention” and “processive retention” are different.<br />出版者許可を得て登録 続きを見る
