Memory conjunction errors for autobiographical events: more than just familiarity

Two diary studies investigated the prevalence of memory conjunction errors for real-life events. In both studies, participants completed detailed diary pages over the course of several weeks. Participants in both diary studies committed memory conjunction errors on a later recognition memory test. In the second diary study participants also made remember/know judgements. For a large proportion of their memory conjunction errors participants indicated that they "remembered" the event occurring in that context. These diary studies demonstrate that memory conjunction errors do occur for autobiographical memories, and these errors can seem compelling.     

Influence of recollection and plausibility on age-related deficits in associative memory

Age-related declines in associative memory are proposed to result from deficits in older adults' ability to recollect the past. The present experiment investigated the ability of older adults to compensate for deficits in recollecting the past by using plausibility. Participants studied a list of word pairs that shared category or rhyme relations. To measure the processes used during the recognition memory test, participants provided self-reported explanations for their memory judgements. Older adults relied primarily on plausibility, and the younger adults relied on both plausibility and recollection. Older adults experienced both positive and negative consequences as a result of using a knowledge-based strategy to compensate for their decreased ability to recollect the past. Specifically, they were just as capable as younger adults at recognising previously studied items and correctly rejecting distractors that were inconsistent with the rule provided at study. However, they falsely recognised distractors that were consistent with that rule more often than younger adults.

Process demands of rejection mechanisms of recognition memory

A surge of research has been conducted to examine memory editing mechanisms that help distinguish accurate from inaccurate memories. In the present experiment, the authors examined the ability of participants to use novelty detection, recollection rejection, and plausibility judgments to reject lures presented on a recognition memory test. Participants studied a list of word pairs that were arranged in a category relationship (both words from the same category) or an unrelated relationship (both words from different categories) under full or divided attention. At test, participants were given a yes/no recognition test in which they were to respond after seeing the test items for 400 ms or 2,800 ms. Some of the test items were rearranged word pairs that were consistent with the study relationship, whereas others were inconsistent with the study relationship. The results demonstrate that the participants required full attention at study to use novelty detection, recollection rejection, and plausibility judgments to reject lures. Moreover, the results indicate that a long response deadline at test was needed for participants to use both recollection rejection and plausibility judgments to reject lures.     

Memory editing: Knowledge, criteria, and alignment

Within this article, a general organisational framework for this special issue of Memory is provided. The organising structure is based on a straightforward hypothesis that editing mechanisms are based on three independent constructs: knowledge, criteria, and alignment. Supporting evidence for this general framework taken from the literature generally, and this special issue of Memory specifically, is reviewed. In the concluding section, future directions for research in the area of memory editing are outlined.     

Global gist extraction in children and adults

The DRM paradigm was used to examine the role of global gist extraction in producing false memories in children and adults. First-graders, third-graders, and adults watched a videotape of a woman reading seven DRM lists, and then took a recognition memory test. Blocked (vs random) presentation and instructions to attend to the theme of lists were manipulated to enhance gist processing. In the first experiment, blocked presentation increased false recognition relative to random presentation in adults but not in first-graders or third-graders. In the second experiment, instructions to attend to list themes increased false recognition in third-graders and not in adults or first-graders. The results suggest a developmental pattern in which children become more adept at global gist extraction as they get older. These results are consistent with fuzzy trace theory's prediction of better gist processing as children grow older.
