Memory for ages of unfamiliar faces was examined in an associative memory task to determine whether generation as well as schematic support (cues from faces) would enhance later cued recall of the age information and reduce older adults' associative deficit. Participants studied faces and were either presented with the age or first had to guess before being shown the correct age. Later, participants were given a cued-recall test. Both younger and older adults exhibited associative memory enhancements from first generating the ages at encoding (a generation effect) despite the fact the initial generation was often inaccurate. Although older adults recalled fewer ages overall compared with younger adults, older adults were able to remember the age information for older faces equally as well as younger adults. However, when errors committed during generation were large and when schematic support was not available to support encoding and retrieval (when the age information was inconsistent given the cues from the face), generating was no longer beneficial for either older or younger adults. Thus, although older adults display an associative deficit when remembering specific age-face associations, this can be reduced through the use of prior knowledge and generation at encoding.
在联想记忆任务中检查了对不熟悉面孔年龄的记忆,以确定生成以及图式支持(来自面孔的提示)是否会增强以后提示回忆年龄信息,并减少老年人的联想缺陷。参与者研究了面孔,要么直接呈现年龄,要么必须先猜测,然后再显示正确的年龄。之后,参与者接受了提示回忆测试。尽管最初的生成通常不准确,但无论是年轻人还是老年人,在编码时首先生成年龄都会增强联想记忆(生成效应)。尽管与年轻人相比,老年人整体上回忆的年龄较少,但老年人能够与年轻人一样好地记住较老面孔的年龄信息。但是,当生成过程中的错误较大且图式支持无法用于支持编码和检索时(当根据面孔的提示给出的年龄信息不一致时),生成对老年人或年轻人都不再有益。因此,尽管老年人在记住特定的年龄面孔关联时会表现出联想缺陷,但可以通过在编码时使用先验知识和生成来减少这种缺陷。
