Retrieving information from memory can cause forgetting of related information in memory. This phenomenon is known as retrieval-induced forgetting. In this experiment, we examined age-related differences of inhibitory function in retrieval-induced forgetting by using a cued recall test. Following the cued recall test, a recognition test was conducted to examine the release of inhibition. In the cued recall test, the same amount of retrieval-induced forgetting effect was observed in younger and older people. This result suggests that both younger and older people have an inhibitory function and that this inhibitory function does not decline with age. In the recognition test, for younger people, retrieval-induced forgetting was not observed in both recognition accuracy and reaction time. However, for older people, retrieval-induced forgetting was observed in both accuracy and reaction time. These results suggest that inhibition in retrieval-induced forgetting is gradually released by item-specific cues and that the function of release inhibition may decline with age.
从记忆中提取信息会导致对记忆中相关信息的遗忘。这种现象被称为提取诱发遗忘。在本实验中,我们通过线索回忆测试研究了提取诱发遗忘中抑制功能的年龄差异。线索回忆测试后,进行了再认测试以检验抑制的解除。在线索回忆测试中,年轻人和老年人观察到相同程度的提取诱发遗忘效应。这一结果表明,年轻人和老年人都具有抑制功能,且这种抑制功能不会随年龄下降。在再认测试中,对于年轻人,在再认准确性和反应时间方面均未观察到提取诱发遗忘。然而,对于老年人,在准确性和反应时间方面均观察到了提取诱发遗忘。这些结果表明,提取诱发遗忘中的抑制通过项目特定线索逐渐解除,且抑制解除功能可能随年龄下降。
