The purpose of this study was to determine the effectiveness of semantic cues provided at encoding and during retention for older adults' memory. For the California Verbal Learning Test-II, participants received semantic or nonsemantic cues that were varied across groups at encoding and during the retention interval. Provision of a semantic cue at encoding led to greater semantic clustering at learning, but not increased recall performance. Providing a semantic cue during the retention interval led to better delayed free recall and greater semantic clustering. No group differences in recall or semantic clustering were found at delayed cued recall. The current findings suggest that semantic cues can be beneficial for recalling unstructured information when administered during the retention interval.
本研究的目的是确定在编码时和记忆保持期间提供的语义线索对老年人记忆的有效性。对于加利福尼亚言语学习测试-II,参与者在编码时和记忆保持间隔期间接受了语义或非语义线索,这些线索在不同组之间有所变化。在编码时提供语义线索会导致学习时更大的语义聚类,但不会提高回忆表现。在记忆保持间隔期间提供语义线索会导致更好的延迟自由回忆和更大的语义聚类。在延迟线索回忆中未发现回忆或语义聚类方面的组间差异。当前的研究结果表明,在记忆保持间隔期间给予语义线索有助于回忆无结构信息。
