Older adults sometimes demonstrate a mnemonic "positivity effect," remembering more positive than negative information. The present study examined whether this effect would occur for arousing words (elation vs slaughter) or for nonarousing ones (serenity vs sorrow). The results revealed no positivity effect for arousing words: Young and older adults remembered negative and positive arousing words equally well and more often than neutral words. However, a positivity effect emerged for nonarousing words. Young adults remembered negative nonarousing words better than positive nonarousing items. Older adults remembered positive nonarousing words better than negative nonarousing words and showed no mnemonic benefit for negative nonarousing words as compared with neutral words. These findings suggest that aging preserves responses to arousing information while altering the processing of nonarousing information.
老年人有时会表现出一种记忆方面的“积极效应”,即记住的积极信息多于消极信息。本研究考察了这种效应是否会出现在激发性词汇(兴高采烈与屠杀)或非激发性词汇(宁静与悲伤)上。结果显示,对于激发性词汇不存在积极效应:年轻人和老年人对消极和积极的激发性词汇的记忆效果相同,且比中性词汇的记忆频率更高。然而,对于非激发性词汇出现了积极效应。年轻人对消极非激发性词汇的记忆优于积极非激发性词汇。老年人对积极非激发性词汇的记忆优于消极非激发性词汇,并且与中性词汇相比,对消极非激发性词汇没有记忆优势。这些发现表明,衰老在保留对激发性信息的反应的同时,改变了对非激发性信息的处理。
