Effects of Aging on General and Specific Memory for Impressions.

Despite the number of documented declines in memory with age, memory for socioemotional information can be preserved into older adulthood. These studies assessed whether memory for character information could be preserved with age, and how the general versus specific nature of the information tested affected outcomes. We hypothesized that memory for general impressions would be preserved with age, but that memory for specific details would be impaired. In two experiments, younger and older adults learned character information about individuals characterized as positive, neutral, or negative. Participants then retrieved general impressions and specific information for each individual. The testing conditions in Experiment 2 discouraged deliberate recall. In Experiment 1, we found that younger performed better than older adults on both general and specific memory measures. Although age differences in memory for specific information persisted in Experiment 2, we found that younger and older adults remembered general impressions to a similar extent when testing conditions encouraged the use of “gut impressions” rather than deliberate retrieval from memory. We conclude that aging affects memory for specific character information, but memory for general impressions can be age-equivalent. Furthermore, there is no evidence for a positivity bias or differences in the effects of valence on memory across the age groups.

Abstract recall of a happy memory to repair sad mood in dysphoria: A possible link to negative cognition

The capacity to repair sad mood through the deliberate recall of happy memories has been found to be impaired in dysphoric individuals. Rumination, or adopting an abstract processing mode, has been proposed as a possible mechanism underpinning this effect. In low and high dysphoric participants, we examined the relative consequences of adopting an abstract or concrete processing mode during happy memory recall or engaging in distraction for (1) mood repair and (2) cognitive content. Recalling a happy memory in either an abstract or concrete way resulted in greater happiness than distraction. Engaging in abstract recall of a happy memory resulted in high dysphoric participants generating negative evaluations and negative generalisations. These findings raise the interesting possibility that abstract processing of positive memories has the potential to generate negative cognition.

Feelings of mental pollution subsequent to sexual assault

This paper describes an investigation of the phenomenon of mental pollution in a sample of 50 female victims of sexual assault. Feelings of mental pollution were assessed using an interview and a questionnaire. An experimental procedure was employed to determine if feelings of dirtiness and the urge to wash could be provoked by deliberate attention to the assault memory. Thirty (60%) of the 50 participants reported some feelings of mental pollution subsequent to the assault, and feelings of mental pollution were related to post-assault washing behaviour. Deliberate recall of the assault resulted in stronger feelings of dirtiness and the urge to wash than did deliberate attention to a pleasant memory or scene. Nine women reported washing their hands in response to deliberate recall of the assault. These findings suggest that feelings of mental pollution may be prominent in victims of sexual assault.

Mother-child conversational interactions as events unfold: linkages to subsequent remembering.

The study reported here was designed to examine linkages between mother-child conversational interactions during events and children's subsequent recall of these activities. In this longitudinal investigation, 21 mother-child dyads were observed while they engaged in specially constructed activities when the children were 30, 36, and 42 months of age. Analyses of the children's 1-day and 3-week recall of these events indicated that at all age points, features of the activities that were jointly handled and jointly discussed by the mother and child were better remembered than were features that were either (1) jointly handled and talked about only by the mother, or (2) jointly handled and not discussed. Potential linkages were also explored between incidental memory for personal experiences and deliberate recall of familiar but arbitrary materials. In this regard, children's recall of the special activities was positively correlated with their recall of objects in a deliberate memory task performed at 42 months.

Time Course of Cortical Activations in Implicit and Explicit Recall

The distinction between implicit and explicit retrieval of learned material is central to recent thinking about the neural systems underlying memory. Word stem completion is one task in which subjects can be instructed either to make a deliberate recall (explicit instruction) or to be told to complete the stem with any appropriate word (implicit instruction). Positron emission tomography (PET) studies have indicated that during implicit retrieval, there is reduced blood flow in right posterior areas, whereas some tasks of explicit retrieval involve frontal and hippocampal activation. However, there is no information about the timing of these activations or how implicit and explicit retrieval might be related. We used word stem completion tasks similar to those used in the PET studies, but used high-density electrical recording designed to allow localization of the regions involved in the tasks and to provide temporal information. We found reduced activity for primed words in right posterior cortex corresponding to previous PET results. The reduction occurred within the first 200 msec after input, suggesting early interaction with the information stored in this area. Similar reductions observed during explicit recall of the previously presented words indicate that priming is similar under implicit and explicit conditions. In addition, when priming was not an adequate basis for response, then frontal areas were active. Retrieval of unprimed words under implicit instruction elicited right frontal activation, whereas explicit retrieval activated frontal areas bilaterally. Left frontal and hippocampal activations appear to occur only when the retrieval involved use of the words from the list studied previously.

More or less the same? A memorability analysis on episodic memory tasks in young and older adults.

A relative memorability analysis was conducted on a young (19.5 years, n = 48) and an old (67.0 years, n = 45) age group, using 10 episodic memory tasks (four lists of words, four lists of paired associates, and two texts). Probability of recall of individual items (lists) or idea units (texts) by the older adults could be predicted from probability of recall for the corresponding items or idea units by the young adults, with a median correlation (corrected for test unreliability) of .88. It was found that the same item characteristics predicted recall probability of individual items or idea units in both age groups. For lists of words and texts, no differences were found in the slopes of the regression functions relating item characteristics to recall probability in the two age groups. For 3 of 4 lists of paired associates, the slopes for item characteristics significantly predicting recall probability were reliably larger for the older adults as compared with the young adults. It can be concluded that age differences in deliberate recall are to a large amount quantitative, and not qualitative, in nature.

Narrative and visual spatial recall: Assessment incorporating learning and delayed retention

Abstract We determined whether memory for a complex figure improves (learning occurs) after re-presentation of the stimulus despite a delay, as it does for verbal narrative information in the Babcock-Levy recall procedure. In addition, we compared interdigitated administrations of the verbal and nonverbal tests, which reduce delays to 5 minutes, to separate administrations of each test with delays of 20 minutes. Scoring manuals were written, and interscorer reliabilities in the .90's were obtained. Results indicated that visual-spatial recall improves, that the two delays generated equivalent results and that these measures of visual-spatial and verbal memory are not correlated. The interdigitated sequence may be an efficient battery for measuring deliberate recall and learning of verbal and nonverbal complex information.
