Oh, honey, I already forgot that: strategic control of directed forgetting in older and younger adults

Two experiments investigated list-method directed forgetting with older and younger adults. Using standard directed forgetting instructions, significant forgetting was obtained with younger but not older adults. However, in Experiment 1 older adults showed forgetting with an experimenter-provided strategy that induced a mental context change--specifically, engaging in diversionary thought. Experiment 2 showed that age-related differences in directed forgetting occurred because older adults were less likely than younger adults to initiate a strategy to attempt to forget. When the instructions were revised to downplay their concerns about memory, older adults engaged in effective forgetting strategies and showed significant directed forgetting comparable in magnitude to younger adults. The results highlight the importance of strategic processes in directed forgetting.     

The associative memory deficit of older adults: the role of strategy utilization

Past research has established an associative deficit hypothesis (e.g., M. Naveh-Benjamin, 2000) that attributes part of older adults' poor episodic memory performance to their difficulty in creating and retrieving cohesive episodes. Here, the authors evaluate the degree to which this deficit can be reduced by older adults' use of associative strategies. Young and older adults learned word pairs under either intentional-learning instructions or instructions eliciting associative strategies either at encoding or both at encoding and at retrieval, and they then took tests on their memory for both the components and the associations. Results replicated the associative deficit of older adults under intentional-learning instructions. In addition, they showed that instructions to use appropriate associative strategies during either encoding or, even more so, during encoding and retrieval resulted in a significant decrease in the associative deficit. The theoretical and applied implications of these results are discussed.     

Divergent effects of instructed and reported emotion regulation strategies on children’s memory for emotional information

ABSTRACT

Distraction can reduce adults’ memory for emotion-eliciting information, whereas reappraisal can preserve or enhance it. Yet, when given instructions to use specific emotion regulation (ER) strategies, adults report using other strategies too. The consequences of non-instructed strategy use within instructed ER paradigms are rarely examined. We investigated how both instructed and non-instructed but reported strategies related to memory for emotional information in childhood. Older (N?=?69; 8- to 10-year-olds; 24 girls) and younger (N?=?65; 5- to 7-year-olds; 35 girls) children received instructions to use cognitive distraction, reappraisal, or do nothing (control) before and after viewing a negative emotional film clip. Children were later interviewed about what they remembered about the film, and reported the ER strategies they used during it. Memory did not vary across instructed ER strategy conditions, and reported strategies did not relate to memory differently for older and younger children. Consistent with adult work, reported cognitive distraction related to poorer memory. Different reappraisal types were reported, but only situation-focused reappraisal was linked to better memory. In sum, children’s reported cognitive distraction and reappraisal strategies related to memory for emotional information differently. Thus, ER strategies divergently relate to what children remember about their emotional experiences.     

Instructional manipulations and age differences in memory: now you see them, now you don't.

The instructions for most explicit memory tests use language that emphasizes the memorial component of the task. This language may put older adults at a disadvantage relative to younger adults because older adults believe that their memories have deteriorated. Consequently, typical explicit memory tests may overestimate age-related decline in cognitive performance. In 2 experiments, older and younger adults performed a memory test on newly learned trivia. In both experiments, age differences were obtained when the instructions emphasized the memory component of the task (memory emphasis) but not when the instructions did not emphasize memory (memory neutral). These findings suggest that aspects of the testing situation. such as experimental instructions, may exaggerate age differences in memory performance and need to be considered when designing studies investigating age differences in memory.     

Does a time-monitoring deficit influence older adults' delayed retrieval shift during skill acquisition?

The authors evaluated age-related time-monitoring deficits and their contribution to older adults' reluctance to shift to memory retrieval in the noun-pair lookup (NP) task. Older adults (M = 67 years) showed slower rates of response time (RT) improvements than younger adults (M = 19 years), because of a delayed strategy shift. Older adults estimated scanning latencies as being faster than they actually were and showed poor resolution in discriminating short from long RTs early in practice. The difference in estimated RT for retrieval and scanning strategies predicted retrieval use, independent of actual RT differences. Separate scanning and recognition memory tasks revealed larger time-monitoring differences for older adults than in the NP task. Apparently, the context of heterogeneous RTs as a result of strategy use in the NP task improved older adults' accuracy of RT estimates. RT feedback had complex effects on time-monitoring accuracy, although it generally improved absolute and relative accuracy of RT estimates. Feedback caused older adults to shift more rapidly to the retrieval strategy in the NP task. Results suggest that deficient time monitoring plays a role in older adults' delayed retrieval shift, although other factors (e.g., confidence in the retrieval strategy) also play a role.     

Effet du niveau d’études sur les performances en mémoire épisodique chez des adultes âgés : rôle médiateur de la métamémoire

Educational level is a factor of cognitive reserve and older adults with a higher level of formal education have a better memory performance than those having a lower educational level (Angel et al., 2010; Van Der Elst, Van Boxtel, Van Breukelen, & Jolles, 2005). Memory functioning can also be modulated by the beliefs and knowledge of a person about his/her own memory, that is, by his/her metamemory (Hultsch, Hertzog, & Dixon, 1987). The objective of this study was to examine the role of metamemory as a potential mediator of the effect of educational level on memory performance. Eighty-three older adults (60–80 years) participated in the experiment, they have been divided into two subgroups according to their educational level (high: 14.36 years and low level: 9.85 years). Episodic memory was evaluated with a cued recall task and metamemory by the Metamemory in Adulthood questionnaire (MIA). As shown by previous studies, results indicated that educational level had a significant effect on memory and metamemory, higher educational level was associated to better memory and metamemory capacities. At the MIA questionnaire, older adults with a high educational level affirmed using more internal and external strategies for learning, having higher motivation and perceiving less memory change with aging than older adults with a lower educational level. They also showed that the metamemory dimensions associated to the memory performance differed according to the educational level. For participants with a lower educational level, memory performance was correlated to the participants’ perception about their memory capacity and their knowledge about memory tasks, while for participants with a higher educational level, memory performance was correlated to the dimensions linked to memory control (strategies and motivation). Finally, the group effect was mediated by metamemory, specifically by the use of internal strategies. These results suggest that a prolonged educative experience would be associated to a better capacity to implement adapted strategies, which led individuals to maintain an optimal memory performance.     

A threat in the elder: the impact of task‐instructions,self‐efficacy and performance expectations on memory performance in the elderly

Widely used explicit memory tasks seem to overestimate age‐related differences in memory performance. Social and personal factors may buffer or undermine the effect of age on memory performance. In two studies, the performance of older adults was compared with the performance of younger adults. Tasks were presented either as memory tasks or non‐memory tasks. Older adults' performance on a memory task improved when the task‐instructions did not explicitly emphasize the memory component of the task. In the first study, results revealed that memory self‐efficacy beliefs play a moderator role on the impact of task‐instruction on memory performance, so that lower levels of memory self‐efficacy correlate with lower performance in the memory emphasizing task condition but not in the orientation emphasizing task condition. In a second study actual performance expectations were measured. For older participants only, expectations were sensitive to task‐instructions and mediated the relation between tasks‐instructions and performances. These findings suggest that observed age‐related differences in memory performance may be significantly exaggerated by the testing situation and by a low memory self‐efficacy and low memory performance expectancies prevalent among older adults.

Memory for contextual details: effects of emotion and aging

When individuals are confronted with a complex visual scene that includes some emotional element, memory for the emotional component often is enhanced, whereas memory for peripheral (nonemotional) details is reduced. The present study examined the effects of age and encoding instructions on this effect. With incidental encoding instructions, young and older adults showed this pattern of results, indicating that both groups focused attention on the emotional aspects of the scene. With intentional encoding instructions, young adults no longer showed the effect: They were just as likely to remember peripheral details of negative images as of neutral images. The older adults, in contrast, did not overcome the attentional bias: They continued to show reduced memory for the peripheral elements of the emotional compared with the neutral scenes, even with the intentional encoding instructions.     

Destination memory in social interaction: better memory for older than for younger destinations in normal aging?

Destination memory, a memory component allowing the attribution of information to its appropriate receiver (e.g., to whom did I lend my pen?), is compromised in normal aging. The present paper investigated whether older adults might show better memory for older destinations than for younger destinations. This hypothesis is based on empirical research showing better memory for older faces than for younger faces in older adults. Forty-one older adults and 44 younger adults were asked to tell proverbs to older and younger destinations (i.e., coloured faces). On a later recognition test, participants had to decide whether they had previously told some proverb to an older/younger destination or not. Prior to this task, participants reported their frequency of contact with other-age groups. The results showed lower destination memory in older adults than in younger adults. Interestingly, older adults displayed better memory for older than for younger destinations. The opposite pattern was seen in younger adults. The low memory for younger destinations, as observed in older adults, was significantly correlated with limited exposure to younger individuals. These findings suggest that for older adults, the social experience can play a crucial role in the destination memory, at least as far as exposure to other-age groups is concerned.     

Self-initiated object-location memory in young and older adults

The present study explored self-initiated object-location memory in ecological contexts, as aspect of memory that is largely absent from the research literature. Young and older adults memorized objects-location associations they selected themselves or object-location associations provided to them, and elaborated on the strategy they used when selecting the locations themselves. Retrieval took place 30 min and 1 month after encoding. The results showed an age-related decline in self-initiated and provided object-location memory. Older adults benefited from self-initiation more than young adults when tested after 30 min, while the benefit was equal when tested after 1 month. Furthermore, elaboration enhanced memory only in older adults, and only after 30 min. Both age groups used deep encoding strategies on the majority of the trials, but their percentage was lower in older adults. Overall, the study demonstrated the processes involved in self-initiated object-location memory, which is an essential part of everyday functioning.     

Age differences in perceptions of memory strategy effectiveness for recent and remote memory

We examined whether young and older adults hold different beliefs about the effectiveness of memory strategies for specific types of memory tasks and whether memory strategies are perceived to be differentially effective for young, middle-aged, and older targets. Participants rated the effectiveness of five memory strategies for 10 memory tasks at three target ages (20, 50, and 80 years old). Older adults did not strongly differentiate strategy effectiveness, viewing most strategies as similarly effective across memory tasks. Young adults held strategy-specific beliefs, endorsing external aids and physical health as more effective than a positive attitude or internal strategies, without substantial differentiation based on task. We also found differences in anticipated strategy effectiveness for targets of different ages. Older adults described cognitive and physical health strategies as more effective for older than middle-aged targets, whereas young adults expected these strategies to be equally effective for middle-aged and older target adults.     

Aging effects in sequential modulations of poorer-strategy effects during execution of memory strategies

In this study, we asked young adults and older adults to encode pairs of words. For each item, they were told which strategy to use, interactive imagery or rote repetition. Data revealed poorer-strategy effects in both young adults and older adults: Participants obtained better performance when executing better strategies (i.e., interactive-imagery strategy to encode pairs of concrete words; rote-repetition strategy on pairs of abstract words) than with poorer strategies (i.e., interactive-imagery strategy on pairs of abstract words; rote-repetition strategy on pairs of concrete words). Crucially, we showed that sequential modulations of poorer-strategy effects (i.e., poorer-strategy effects being larger when previous items were encoded with better relative to poorer strategies), previously demonstrated in arithmetic, generalise to memory strategies. We also found reduced sequential modulations of poorer-strategy effects in older adults relative to young adults. Finally, sequential modulations of poorer-strategy effects correlated with measures of cognitive control processes, suggesting that these processes underlie efficient trial-to-trial modulations during strategy execution. Differences in correlations with cognitive control processes were also found between older adults and young adults. These findings have important implications regarding mechanisms underlying memory strategy execution and age differences in memory performance.     

Young and older adults' beliefs about effective ways to mitigate age-related memory decline

This study investigated whether young and older adults vary in their beliefs about the impact of various mitigating factors on age-related memory decline. Eighty young (ages 18-23) and 80 older (ages 60-82) participants reported their beliefs about their own memory abilities and the strategies that they use in their everyday lives to attempt to control their memory. Participants also reported their beliefs about memory change with age for hypothetical target individuals who were described as using (or not using) various means to mitigate memory decline. There were no age differences in personal beliefs about control over current or future memory ability. However, the two age groups differed in the types of strategies they used in their everyday life to control their memory. Young adults were more likely to use internal memory strategies, whereas older adults were more likely to focus on cognitive exercise and maintaining physical health as ways to optimize their memory ability. There were no age differences in rated memory change across the life span in hypothetical individuals. Both young and older adults perceived strategies related to improving physical and cognitive health as effective means of mitigating memory loss with age, whereas internal memory strategies were perceived as less effective means for controlling age-related memory decline.     

Breaking down unitization: Is the whole greater than the sum of its parts?

Memory impairments are often observed in aging. Specifically, older adults have difficulty binding together disparate elements (relational memory). We have recently shown that a cognitive strategy known as unitization can mitigate impaired relational learning in the transverse patterning task (TP) in both amnesia and healthy aging. This strategy allows items to be fused together through an interaction such that one item acts upon another. In the context of TP, unitization is comprised of three component processes: (1) fusion, (2) motion, and (3) semantic comprehension of action/consequence sequences. Here, we examine which of these components are sufficient to mitigate age-related impairments. Four groups of older adults were given either the full unitization strategy or one of the three component strategies. Each group of older adults showed impairments in memory for the relations among items under standard training instructions relative to a threshold that marks learning of a winner-take-all rule (elemental threshold). However, participants who were given either the full unitization strategy or the action/consequence-only strategy showed improved performance, which was maintained following the 1-hour delay. Therefore, semantically rich action/consequence interactions are sufficient to mitigate age-related relational memory impairments.

考察了日常人际问题解决中老年人的悲伤情绪体验和情绪调节策略与青年人的差异,以及年龄和人格特质的作用。共45名老年人和59名青年人接受半结构化访谈和人格特质测量。结果表明：（1）以教育水平为协变量的方差分析表明,老年人和青年人的悲伤情绪体验没有显著差异。老年人的被动情绪调节策略的使用和青年人存在显著差异;（2）老年人的被动情绪调节策略不但与年龄有关,而且与悲伤情绪体验有关。悲伤情绪体验可以显著预测其被动情绪调节策略使用;（3）老年人的悲伤情绪体验与人格特质神经质维度存在显著正相关;（4）老年人与年轻人的被动情绪调节策略都与悲伤情绪有关,但老年人的被动情绪调节策略不能由人格特质显著预测,而青年人的被动调节策略还可以由人格特质内外向维度显著预测。人格特质的内外向维度对老年人和青年人的前摄性情绪调节策略的预测效应是一致的。最后针对老年人的悲伤情绪体验和情绪调节策略的意义进行了讨论。     

The impact of beliefs about face recognition ability on memory retrieval processes in young and older adults

This study examined whether beliefs about face recognition ability differentially influence memory retrieval in older compared to young adults. Participants evaluated their ability to recognise faces and were also given information about their ability to perceive and recognise faces. The information was ostensibly based on an objective measure of their ability, but in actuality, participants had been randomly assigned the information they received (high ability, low ability or no information control). Following this information, face recognition accuracy for a set of previously studied faces was measured using a remember–know memory paradigm. Older adults rated their ability to recognise faces as poorer compared to young adults. Additionally, negative information about face recognition ability improved only older adults' ability to recognise a previously seen face. Older adults were also found to engage in more familiarity than item-specific processing than young adults, but information about their face recognition ability did not affect face processing style. The role that older adults' memory beliefs have in the meta-cognitive strategies they employ is discussed.     

Cognitive consequences of expressive regulation in older adults

Previous research has suggested that older and young adults are equally able to regulate their outward expressions of emotion and that the regulation of emotional expression in younger adults results in decreased memory for the emotional stimulus. In the current study, we examined whether older adults show this same memory effect. Older and young adults viewed positive and negative emotional pictures under instructions to view the pictures naturally, enhance their facial expressions, or suppress their facial expressions. Older and young adults showed equivalent outward regulation of expression, but suppressing their emotional expressions led to reduced memory for emotional stimuli only in the young adults. The results suggest that older and young adults are achieving control of their expressions through different mechanisms or strategies.     

The effect of forced recall on illusory recollection in younger and older adults

The effect of an initial forced recall test on later recall and recognition tests was examined in younger and older adults. Subjects were presented with categorized word lists and given an initial test under standard cued recall instructions (with a warning against guessing) or forced recall instructions (that required guessing); subjects were later given a cued recall test for the original list items. In 2 experiments, initial forced recall resulted in higher levels of illusory memories on subsequent tests (relative to initial cued recall), especially for older adults. Older adults were more likely to say they remembered rather than knew that forced guesses had occurred in the original study episode. The effect persisted despite a strong warning against making errors in Experiment 2. When a source monitoring test was given, older adults had more difficulty than younger adults in identifying the source of items they had originally produced as guesses. If conditions encourage subjects to guess on a first memory test, they are likely to recollect these guesses as actual memories on later tests. This effect is exaggerated in older adults, probably because of their greater source monitoring difficulties. Both dual process and source monitoring theories provide insight into these findings.     

Mediator-based encoding strategies in source monitoring in young and older adults

Past research has examined the contribution of mediator-based encoding strategies (interactive imagery and sentence generation) to individual (particularly age-related) differences in associative memory exclusively in the paired-associates paradigm. In the present study, we examined young and older adults' mediator-based strategy use on source-monitoring tasks. Participants spontaneously used mediator-based strategies to encode about 30% to 40% of word-source pairs and were able to follow instructions to use the specific mediator-based strategy of interactive imagery; mediator-based strategy use was associated with higher source memory and explained variance in source memory. There were no age-related differences in the patterns of mediator-based strategy production and utilization. Age-related differences in source memory were explained by age-related declines in the ability to bind information in memory (incidental memory for digit-symbol associations) but not by encoding strategy production. Results underscore the importance of assessing encoding strategy use for understanding individual differences in source memory. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

In some individuals, noise appears to have an adverse effect on memory recall. This decrement may result from a shift in the memory strategy being employed. Studies have shown memory strategies used by persons with an internal locus of control differ from those used by persons with an external locus of control. The present investigation asked subjects who were classified as either internal or external in locus of control to recall words presented under conditions of noise and of quiet. Word recall was aided by providing subjects with potential memory strategies. Each word list included words from meaningful content categories (which favor a semantic strategy) and word pairs that rhymed (which favor a perceptual strategy). Though internal and external subjects did not differ in total words recalled, they did differ in their use of strategies. Whereas internal subjects' strategies were unaffected by noise, external subjects decreased their use of the higher level semantic memory strategy (content categories) and increased their use of lower level perpetual (rhymes) strategy in the noise condition. The results are discussed in terms of a differential arousal hypothesis.
