Abstract: In the present study, two experiments with selective task paradigm were conducted to investigate the influences of value-item interval and item presentation duration on the effect of value-directed metamemory. Experiment 1 explored whether different value-item intervals(0s, 1s, and 2s)would affect selectivity index(SI)and memory performance. Results showed that the value-directed metamemory was still existed on 1s interval condition but disappeared on 2s interval condition. Experiment 2 inspected whether the item presentation duration would influence the value-directed metamemory further. Two conditions with value-directed selectivity from Experiment 1 were used with expanded longer item presentation duration(4.5s). Results showed that the SIs descended significantly in both two conditions. However, the memory performance of high-value items and low-value items both increased with the item presentation duration increasing, which showed a separation phenomenon between metamemory and memory. In conclusion, value-directed metamemory is affected by both value-item interval and item presentation duration.

摘要: 采用选择性任务范式,用2个实验考察价值-项目间隔和项目呈现时长对价值导向元记忆的影响。实验1考察不同价值-项目间隔(无, 1s, 2s)时被试的选择性记忆指标SI和记忆成绩。结果发现,随价值-项目间隔增加,被试的记忆选择性逐渐下降,间隔1s时对高价值项目的选择性仍存在,但间隔2s时消失;实验2选取实验1的两种价值-项目间隔(无, 1s)条件,延长其项目呈现时间至4.5s,考察项目呈现时间对价值导向元记忆的影响。结果发现,两种价值-项目间隔条件下记忆选择性水平(SI)均显著降低,但对高价值项目的选择性加工优势并没消失。结论:价值导向元记忆受价值-项目间隔和项目呈现时间的影响。
