Prospective memory deficits are associated with unemployment in persons living with HIV infection.

Objective: To determine whether deficits in prospective memory (i.e., “remembering to remember”) confer an increased risk of unemployment in individuals living with chronic HIV infection. Methods: Fifty-nine Unemployed and 49 Employed individuals with HIV infection underwent comprehensive neuropsychological and medical evaluations, including measures of prospective memory. Results: The Unemployed participants demonstrated significantly lower performance on time- and event-based prospective memory, which was primarily characterized by errors of omission. Importantly, prospective memory impairment was an independent predictor of unemployment when considered alongside other neurocognitive abilities, mood disturbance, and HIV disease severity. Conclusions: Prospective memory impairment is a salient predictor of unemployment in persons living with HIV infection and might be considered in screening for unemployment risk and developing vocational rehabilitation plans.

Recollection-based prospective metamemory judgments are more accurate than those based on confidence: Judgments of remembering and knowing (JORKS).

Five experiments were conducted to examine whether the nature of the information that is monitored during prospective metamemory judgments affected the relative accuracy of those judgments. We compared item-by-item judgments of learning (JOLs), which involved participants determining how confident they were that they would remember studied items, with judgments of remembering and knowing (JORKs), which involved participants determining whether studied items would later be accompanied by contextual details (i.e., remembering) or would not (i.e., knowing). JORKs were more accurate than JOLs when remember–know or confidence judgments were made at test and when cued recall was the outcome measure, but not for yes–no recognition. We conclude that the accuracy of metamemory judgments depends on the nature of the information monitored during study and test and that metamemory monitoring can be improved if participants are asked to base their judgments on contextual details rather than on confidence. These data support the contention that metamemory decisions can be based on qualitatively distinct cues, rather than an overall memory strength signal.

Special issue editorial: Prospective memory in 2010.

In order to raise awareness of prospective memory, this special issue features contemporary research on the topic. The occasion for a special issue was the 3rd International Conference on Prospective Memory, which was held in July 2010 in Vancouver, and which brought together nearly 100 scientists from 16 different countries. The conference showcased new research, as well as a host of breakthrough discoveries and methodological insights, and it served to underscore why prospective memory deserves and is likely to receive more prominence in the future. As has been and continues to be the case for retrospective memory, however, most prospective memory research seems to be focused on its episodic component, on questions such as the following: Once a plan has been made, and my attention has turned elsewhere, how does that plan come back to mind at the appropriate time or context? Why do plans sometimes to pop into mind all of the time, including when our attention ought to be focused elsewhere? Why does an obvious cue, such as the mailbox in my way, sometimes fail to reactivate a previous intention? What strategies, if any, are available for improving prospective memory? The articles in this issue address these and related questions. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Control of cost in prospective memory: Evidence for spontaneous retrieval processes.

To examine the processes that support prospective remembering, previous research has often examined whether the presence of a prospective memory task slows overall responding on an ongoing task. Although slowed task performance suggests that monitoring is present, this method does not clearly establish whether monitoring is functionally related to prospective memory performance. According to the multiprocess theory (McDaniel & Einstein, 2000), monitoring should be necessary to prospective memory performance with nonfocal cues but not with focal cues. To test this hypothesis, we varied monitoring by presenting items that were related (or unrelated) to the prospective memory task proximal to target events. Notably, whereas monitoring proximal to target events led to a large increase in nonfocal prospective memory performance, focal prospective remembering was high in the absence of monitoring, and monitoring in this condition provided no additional benefits. These results suggest that when monitoring is absent, spontaneous retrieval processes can support focal prospective remembering. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Prospective memory and task interference in a continuous monitoring dynamic display task.

Theories and methods from the prospective memory literature were used to anticipate how individuals would maintain and retrieve intentions in a continuous monitoring dynamic display task. Participants accepted aircraft into sectors and detected aircraft conflicts during an air traffic control simulation. They were sometimes required to substitute new actions for routine actions when accepting aircraft traveling at certain speeds or altitudes, or with certain call signs. In Experiment 1, prospective memory error increased with intent to deviate from strong compared to weak routine, and this effect was larger for altitude intentions compared to speed intentions. In addition, errors increased when intentions were general compared to specific. Participants also missed more conflicts when deviating from strong compared to weak routine. In Experiment 2, errors increased for intentions nonfocal to ongoing tasks compared to focal, and this effect was larger for altitude intentions compared to call sign intentions. Participants were slower to accept aircraft when holding nonfocal compared to focal intentions, and slower to accept aircraft and detect conflicts when holding focal intentions compared to no intentions. These findings are consistent with theories that assume that individuals allocate limited-capacity attentional resources to prospective memory tasks. Increased error for altitude intentions, together with the effect of routine strength, suggest a vulnerability to error with increased strength of association between prospective memory cues and competing ongoing tasks. Ongoing tasks that focus attention on cues may sometimes impair, rather than benefit, intention retrieval. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Prospective memory and the efficacy of a memory strategy in multiple sclerosis.

Prospective memory (PM), which is the ability to remember to carry out actions that are planned for the future, plays an important role in professional and social life as well as in activities of daily living. This study examined PM performance among adults with multiple sclerosis (MS) and evaluated the efficacy of a mnemonic strategy, implementation intentions. Compared to controls, adults with MS were impaired on PM, both in terms of acting when encountering the correct circumstances (prospective component) and in terms of remembering the correct action to perform (retrospective component). The prospective-component deficit was greater for tasks that depended on more resource-demanding cognitive processes and smaller on tasks that could be performed more automatically. Use of implementation intentions improved MS-group performance on the prospective component, particularly on the more resource-demanding tasks, consistent with the explanation that implementation intentions improved performance by allowing the use of more automatic processes to perform these PM tasks. Implications for providing environmental support to encourage the use of mnemonic strategies are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A neuropsychological study of fact memory and source amnesia.

We investigated the ability of amnesic patients to learn new facts (e.g., Angel Falls is located in Venezuela) and also to remember where and when the facts were learned (i.e., source memory). To assess the susceptibility of fact and source memory to retrograde amnesia, patients prescribed electroconvulsive therapy were presented facts prior to the first treatment and were tested after their second treatment. All amnesic patients exhibited marked fact memory impairment. In addition, some amnesic patients exhibited source amnesia (i.e., they recalled a few facts but then could not remember where or when those facts had been learned). Source amnesia was unrelated to the severity of the memory deficit itself, because patients who exhibited source amnesia recalled as many facts as the patients who did not. These results show that the deficit in amnesia includes an impairment in acquiring and retaining new facts. Source amnesia can also occur, but it is dissociable from impaired recall and recognition and appears to reflect difficulty in remembering the specific context in which information is acquired. The findings are discussed in terms of their significance for how memory is organized. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Implementation intentions: Strong effects of simple plans.

When people encounter problems in translating their goals into action (e.g., failing to get started, becoming distracted, or falling into bad habits), they may strategically call on automatic processes in an attempt to secure goal attainment. This can be achieved by plans in the form of implementation intentions that link anticipated critical situations to goal-directed responses ("Whenever situation x arises, I will initiate the goal-directed response y!"). Implementation intentions delegate the control of goal-directed responses to anticipated situational cues, which (when actually encountered) elicit these responses automatically. A program of research demonstrates that implementation intentions further the attainment of goals, and it reveals the underlying processes.

The role of processing resources in age-related prospective and retrospective memory within old age.

This study investigated the role of processing speed and working memory in prospective and retrospective memory (i.e., free recall) performance within old age. The aim was to examine age-related differences in both memory domains within the age range of 65 to 80 years. The sample consisted of 361 older adults from Wave 1 data of the Zurich Longitudinal Study on Cognitive Aging. Using structural equation modeling, prospective memory, free recall, working memory, and processing speed were identified as latent constructs. Age effects were found to be larger for prospective memory than for free recall. Furthermore, when controlling for individual differences in working memory and processing speed, unique age effects remained for prospective, but not retrospective, memory performance. Results indicate that, within old age, prospective memory represents a distinct memory construct that is partially independent of age-related individual differences in speed of processing, working memory, and retrospective memory.

Aging and prospective memory: The influence of increased task demands at encoding and retrieval.

A feature of prospective memory tasks is that they tend to be embedded into other background activities. Two experiments examined how the demands of these background activities affect age differences in prospective memory. The first experiment showed that increasing the demands of the background activities (by adding a digit-monitoring task) significantly reduced prospective memory performance. Planned comparisons revealed that age differences in prospective memory were reliable only in the more demanding background condition. The second experiment revealed significant prospective memory declines when the demands were selectively increased at encoding for both younger and older adults. When the demands were selectively increased at retrieval, older adults were particularly affected. The authors propose a model that relies on both automatic retrieval processes and working memory resources to explain prospective memory remembering.

The source of adult age differences in event-based prospective memory: A multinomial modeling approach.

Event-based prospective memory involves remembering to perform an action in response to a particular future event. Normal younger and older adults performed event-based prospective memory tasks in 2 experiments. The authors applied a formal multinomial processing tree model of prospective memory (Smith & Bayen, 2004) to disentangle age differences in the prospective component (remembering that you have to do something) and the retrospective component (remembering when to perform the action) of prospective memory performance. The modeling results, as well as more traditional analyses, indicate age differences in the resource-demanding prospective component.

Temporal accent structure and the remembering of filmed narratives.

Examined the effects of temporal accent structure on the remembering of filmed narratives by varying the placement and number of commercial breaks. Commercials either highlighted a story's underlying organization by occurring between major episode boundaries (i.e., at breakpoint locations) or obscured this structural arrangement by occurring within episodes (i.e., at nonbreakpoints). Relative to the accentuation of nonbreakpoints, results indicated that the attentional highlighting of episode boundaries yielded higher recall and recognition performance and better memory for temporal order information and details from the story's plot. Selective recall and recognition of breakpoint scenes was significantly higher than that of nonbreakpoints, suggesting that people use episode boundaries as referents for attending and remembering. These findings illustrate certain structural invariants across environmental events and ways in which event structure can be used in remembering.

The influence of attention at encoding on direct and indirect remembering

The relation between attention at encoding and direct (i.e., recognition) versus indirect (i.e., rapid reading) remembering was investigated. In Experiments 1 and 2, color of print indicated whether to read an individual word aloud or to ignore it. This attentional manipulation reduced direct but not indirect remembering for the ignored words relative to the attended words. Apparently direct remembering is extremely dependent on attention at encoding. In Experiment 3, however, presenting two words simultaneously at study, with color now signifying which word to read and which to ignore, eliminated this dissociative effect of attention. Ignored words were not remembered on either test, although attended words were remembered well on both. Mere exposure is not sufficient to produce indirect remembering: Stimuli must be attended. Ignoring one stimulus in favor of processing another stimulus that is simultaneously presented and equally salient may prevent even the minimal attentional requirements of indirect remembering from being met, let alone the more stringent requirements of direct remembering.     

External and internal memory aids: When and how often do we use them?

Examined, in 3 experiments with a total of 489 undergraduates, the kinds of memory aids people use to help them remember in their daily lives. Depending on the situation, they may use internal aids (e.g., mental rehearsal, imagery) of the types usually studied in the laboratory or external aids (e.g., reminder notes, asking someone else), which are rarely investigated but may be often used. Ss' ratings and task performance indicated that they used external memory aids more often than internal aids (a) to prepare for future remembering than to remember past situations, (b) to remember spatial tasks than to remember verbal tasks, and (c) to remember to do things in the past than to remember information from the past. External aids were rated as more dependable, easier to use, more accurate, and more preferred than internal ones. Results indicate that at least 1 external aid, taking notes, affects encoding and not just retrieval, as shown by its facilitation of remembering even when the notes were not available as retrieval cues and its induction of greater categorization of the to-be-remembered items than the use of some other memory aids.

The impact of negative moods on self-enhancing cognitions: The role of reflective versus ruminative mood orientations.

This research program examined how self-focused attention to feelings affects the relation between mood negativity and self-enhancing thought. The primary hypothesis was that the particular manner in which people focus on their moods (reflective vs. ruminative) determines whether they reveal positive (i.e., mood-incongruent) or negative (i.e., mood-congruent) self-relevant thoughts in response to negative moods. Studies 1-4 revealed that social comparisons, temporal comparisons, and other self-enhancing cognitions (i.e., attributions, disidentification, relationship evaluations) are more likely to be mood incongruent when people adopt a reflective orientation to their negative feelings and more likely to be mood congruent when they adopt a ruminative orientation. Additionally, moods and mood orientations affected self-enhancing thoughts through the mediating influence of mood regulation goals and intentions (Studies 5 and 6).

Destination memory impairment in older people.

Older adults are assumed to have poor destination memory—knowing to whom they tell particular information—and anecdotes about them repeating stories to the same people are cited as informal evidence for this claim. Experiment 1 assessed young and older adults' destination memory by having participants tell facts (e.g., “A dime has 118 ridges around its edge”) to pictures of famous people (e.g., Oprah Winfrey). Surprise recognition memory tests, which also assessed confidence, revealed that older adults, compared to young adults, were disproportionately impaired on destination memory relative to spared memory for the individual components (i.e., facts, faces) of the episode. Older adults also were more confident that they had not told a fact to a particular person when they actually had (i.e., a miss); this presumably causes them to repeat information more often than young adults. When the direction of information transfer was reversed in Experiment 2, such that the famous people shared information with the participants (i.e., a source memory experiment), age-related memory differences disappeared. In contrast to the destination memory experiment, older adults in the source memory experiment were more confident than young adults that someone had shared a fact with them when a different person actually had shared the fact (i.e., a false alarm). Overall, accuracy and confidence jointly influence age-related changes to destination memory, a fundamental component of successful communication.

Associative recognition of face pairs by younger and older adults: The role of familiarity-based processing.

Previous research suggested that older adults have a specific impairment in remembering verbal associative information, but it is unclear how elaboration and familiarity might influence this deficit in situations that involve perceptual processing. In the present experiments, younger and older participants studied male-female pairs of faces. Participants were then administered an associative recognition test consisting of previously studied pairs, pairs that contained previously studied items that were not studied together (i.e., conjunction pairs), and entirely new pairs of faces, and participants were instructed to identify pairs that had been presented together at study. Overall, participants were successful at recognizing previously presented pairs but were highly likely to mistakenly endorse conjunction pairs. This pattern was more pronounced for older adults, especially when items were repeated at encoding. Such data suggest that memory for face pairs relies largely on the familiarity of each face and not on a more precise recollection of associative information.

Asian international students' intentions to seek counseling: Integrating cognitive and cultural predictors.

This study integrated several cognitive and cultural predictors of Asian international students' intentions to seek counseling. Data from 295 Asian international students were used to determine whether help-seeking intentions could be predicted by a combination of cognitive variables (i.e., counseling attitudes and stigma concerns) and cultural factors (i.e., acculturation, Asian values, and loss-of-face concerns). Data supported a partially mediated model, such that participants who endorsed more traditional Asian values reported less positive counseling attitudes and lower help-seeking intentions. Contrary to expectations, however, loss-of-face and stigma concerns were associated with stronger intentions to seek counseling, which may have been due to participants' fears of sharing psychological problems with significant others and preference for the confidential nature of the counseling relationship.

Specific- and Partial-Source Memory: Effects of Aging.

Normal aging can be associated with impairments in source memory (recollecting an event's context). This study examined the effects of aging on specific-source memory (e.g., remembering which of 4 people spoke a word) and partial-source memory (e.g., remembering the gender of the person who spoke the word). When young and older adults were matched in terms of old-new recognition, age-related deficits were observed on both specific- and partial-source recollection. When the groups were matched on partial-source performance, no disproportionate specific-source impairment was seen. The results suggest that aging does not differentially affect specific- versus partial-source memory. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
