Age-related differences in responses to thoughts of one's own death: Mortality salience and judgments of moral transgressions.

Two experiments explored age differences in response to reminders of death. Terror management research has shown that death reminders lead to increased adherence to and defense of one's cultural worldview. In Study 1, the effect of mortality salience (MS) on evaluations of moral transgressions made by younger and older adults was compared. Whereas younger adults showed the typical pattern of harsher judgments in response to MS, older adults did not. Study 2 compared younger and older adults' responses to both the typical MS induction and a more subtle death reminder. Whereas younger adults responded to both MS inductions with harsher evaluations, older adults made significantly less harsh evaluations after the subtle MS induction. Explanations for this developmental shift in responses to reminders of death are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

More data-driven processing at retrieval reduces age-related memory deficits.

The environmental support hypothesis postulates that it may be possible to reduce older adults' deficits in episodic memory by providing environmental support at the encoding and/or retrieval phases. To examine the validity of this hypothesis, we varied the amount of retrieval support by manipulating data-driven processes. Young and older adults performed a word-stem cued recall task under a low data-driven condition (LDDC) in which the retrieval cue comprised 3 letters, and a higher data-driven condition (HDDC) in which the cue comprised 4 letters. Older adults benefitted more than younger adults from the additional support. Older adults exhibited a large deficit relative to younger adults in the LDDC condition but no age differences were found in the HDDC condition. These findings demonstrate that age-related memory deficits can be reduced by increasing the environmental support at retrieval associated with the data-driven component of retrieval processing.

Differential memory changes with age: Exact retrieval versus plausible inference.

Conducted 2 experiments on the use of direct retrieval and plausibility memory strategies in elderly and college-age adults. In Exp I, which used an episodic memory task, data were obtained from 49 65–80 yr old college alumni and from 58 college students who had served in a previous study by the 1st author (see record 1983-02731-001). Findings indicate that older Ss effectively used the plausibility strategy but performed more poorly than younger Ss when the direct retrieval strategy was required. Results of Exp II, using 18 college alumni (8 Ss aged 20–31 yrs, 10 Ss aged 64–75 yrs) with a semantic memory task, show that older Ss' accuracy was essentially undistinguishable from that of younger Ss as long as a plausibility judgment process produced the correct response. It is argued that careful inspection is a much more costly process for older adults than it is for young adults but that plausibility judgments and feature overlap processes are equally easy for both age groups.

Biased recollections in older adults: The role of implicit theories of aging.

Explored how older adults recall the traits they possessed at an earlier age. It was hypothesized that older adults' recollections would be related to their theories about aging. In Study 1, a group of older Ss provided their theories concerning how various traits change with age. Another group of older Ss rated their current status on these traits and recalled the status they possessed at a younger age. In addition, a group of younger adults rated their current status on the same traits. On traits theorized to increase with age, older Ss recalled themselves as possessing lower levels at an earlier age than the younger group reported possessing. On traits theorized to decrease with age, older Ss recalled themselves as possessing higher levels at an earlier age than the younger group reported possessing. Study 2 indicated that this effect is obtained regardless of trait positivity. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Decreasing complexity of affective space in older adults lower on cognitive control: Affective effects in a nonaffective task and with nonaffective stimuli.

Many theoretical accounts predict that as people age, they rely increasingly on affect. At least one account (Dynamic Integration Theory) makes the additional prediction that an accompanying effect of aging is a narrowing of affective space. These predictions were tested in the context of the relatively automatic low-level cognitive process of lexical access (auditory word recognition). Experiment 1 used emotion words and Experiment 2 used nonemotion words. Both experiments provided support for both predictions. Compared to younger adults (ns = 36 and 56), older adults (ns = 36 and 54) showed larger but less complex effects of dimensions of affective connotation. In addition, older adults with more cognitive resources showed a data pattern like that of younger adults, while those with fewer resources did not. Affective effects emerge even in nonaffective contexts. The tight link between affect and cognition is discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Temperature-related expression of the vacuolar aspartic proteinase (APR1) gene and beta-N-acetylglucosaminidase (HEX1) gene during Candida albicans morphogenesis

An experiment was conducted to compare the functional performance of younger and older adults on familiar and unfamiliar tasks under 2 conditions of perceived control. Specifically, the relation between age and motor and process skills was examined. The familiar tasks were simple cooking tasks, whereas the unfamiliar tasks were contrived, meaningless tasks developed for this study. Younger and older adults did not differ in the ratings of the familiarity of the tasks, but results from 2 Age x Task x Choice analyses of variance demonstrated a significant age difference for motor and process skills under all conditions. This suggests that older adults demonstrate age-related decline, even with activities that take motivational, experiential, and ecological validity components into account. For the process skills scale, there was also a significant main effect for choice. These results support the concept that perceived control may improve performance, but not differentially for older adults; that is, younger and older adults both demonstrated improved process performance when given their choice of tasks.     

Age differences in choice satisfaction: A positivity effect in decision making.

The authors tested the possibility that older adults show a positivity effect in decision making, by giving younger and older adults the opportunity to choose 1 of 4 products and by examining the participants' satisfaction with their choice. The authors considered whether requiring participants to explicitly evaluate the options before making a choice has an effect on age differences in choice satisfaction. Older adults in the evaluation condition listed more positive and fewer negative attributes than did younger adults and were more satisfied with their decisions than were younger adults. There were no age differences among those who did not evaluate options. This evaluation-dependent elevation of satisfaction among older adults was still present when participants were contacted 2 weeks after the experiment. Age did not influence the accuracy with which participants predicted how their satisfaction would change over time. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Age-differential motivational consequences of optimization versus compensation focus in younger and older adults.

Four studies investigated age-related differences in goal focus in younger and older adults. Studies 1 and 2 confirmed the hypothesis that younger adults are more persistent when the same sensorimotor task offers possibility for optimizing performance than when the task requires counteracting a loss in performance (compensation). In contrast, older adults were more persistent in the compensation than in the optimization condition. Study 3 showed that the age-differential effects of goal focus on persistence were not simply due to perceiving the 2 conditions as easy versus difficult. Study 4 ruled out that the age differences were due to differences in the 2 tasks themselves. Taken together, the studies underscore the importance of situating motivational research into a life span context. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of familiarity of task and choice on the functional performance of younger and older adults.

An experiment was conducted to compare the functional performance of younger and older adults on familiar and unfamiliar tasks under 2 conditions of perceived control. Specifically, the relation between age and motor and process skills was examined. The familiar tasks were simple cooking tasks, whereas the unfamiliar tasks were contrived, meaningless tasks developed for this study. Younger and older adults did not differ in the ratings of the familiarity of the tasks, but results from 2 Age?×?Task?×?Choice analyses of variance demonstrated a significant age difference for motor and process skills under all conditions. This suggests that older adults demonstrate age-related decline, even with activities that take motivational, experiential, and ecological validity components into account. For the process skills scale, there was also a significant main effect for choice. These results support the concept that perceived control may improve performance, but not differentially for older adults; that is, younger and older adults both demonstrated improved process performance when given their choice of tasks.

Older Adults as Adaptive Decision Makers: Evidence From the Iowa Gambling Task.

Older adults process emotional information differently than younger adults and may demonstrate less of a negativity bias on cognitive tasks. The Iowa Gambling Task designed by A. Bechara, H. Damasio, D. Tranel, and A. R. Damasio (1997) has been used to examine the integration of emotion and cognition in a risky-choice decision task and may give insight into differences in the decision-making strategies in younger and older adults. Eighty-eight younger adults (18-34 years) and 67 older adults (65-88 years) completed the Iowa Gambling Task. Using a theoretical decomposition of the task designed by J. R. Busemeyer and J. C. Stout (2002), the authors found that both groups were successful at solving the task but used very different strategies that reflected each group's strength. For younger adults, that strength was learning and memory. For older adults, that strength was an accurate representation of wins and losses (valence).

Updating knowledge about encoding strategies: A componential analysis of learning about strategy effectiveness from task experience.

Researchers have argued for age deficits in learning about the effects of encoding strategies from task experience, partly on the basis of absolute accuracy of metacognitive judgments. However, these findings could be attributed to factors other than age differences in learning. Forty older and 40 younger adults participated in 2 study-test trials in which they studied paired associates with imagery or repetition, predicted recall for the items, attempted recall, and postdicted recall. Recall was greater after imagery than repetition, yet this effect was not fully reflected by predictions made on Trial 1. Although both older and younger adults accurately postdicted recall from Trial 1, absolute accuracy of the predictions made on Trial 2 showed little improvement. By contrast, both age groups demonstrated increases in between-person correlations of predictions with recall, which is inconsistent with age deficits in knowledge updating. Thus, both older and younger adults had updated knowledge about the relative effects of the strategies, but such updating was not evident in the absolute accuracy of the predictions.

Pain mapping during minilaparoscopy in infertile patients without pathology

Multiple myeloma (MM) typically afflicts elderly patients with a median age of 65 years. However, while recently shown to provide superior outcome to standard treatment, high-dose therapy (HDT) has usually been limited to patients up to 65 years. Among 550 patients with MM and a minimum follow-up of 18 months, 49 aged >/=65 years were identified (median age, 67; range, 65 to 76 years). Their outcome was compared with 49 younger pair mates (median, 52; range, 37 to 64 years) selected among the remaining 501 younger patients (<65 years) matched for five previously recognized critical prognostic factors (cytogenetics, beta2-microglobulin, C-reactive protein, albumin, creatinine). Nearly one half had been treated for more than 1 year with standard therapy and about one third had refractory MM. All patients received high-dose melphalan-based therapy; 76% of the younger and 65% of the older group completed a second transplant (P =.3). Sufficient peripheral blood stem cells to support two HDT cycles (CD34 > 5 x 10(6)/kg) were available in 83% of younger and 73% of older patients (P =.2). After HDT, hematopoietic recovery to critical levels of granulocytes (>500/microL) and of platelets (>50,000/microL) proceeded at comparable rates among younger and older subjects with both first and second HDT. The frequency of extramedullary toxicities was comparable. Treatment-related mortality with the first HDT cycle was 2% in younger and 8% among older subjects, whereas no mortality was encountered with the second transplant procedure. Comparing younger/older subjects, median durations of event-free and overall survival were 2.8/1.5 years (P =.2) and 4.8/3.3 years (P =.4). Multivariate analysis showed pretransplant cytogenetics and beta2-microglobulin levels as critical prognostic features for both event-free and overall survival, whereas age was insignificant for both endpoints (P =.2/.8). Thus, age is not a biologically adverse parameter for patients with MM receiving high-dose melphalan-based therapy with peripheral blood stem cell support and, hence, should not constitute an exclusion criterion for participation in what appears to be superior therapy for symptomatic MM.     

Framing of task performance strategies: effects on performance in a multiattribute dynamic decision making environment

It is well documented that the way a static choice task is "framed" can dramatically alter choice behavior, often leading to observable preference reversals. This framing effect appears to result from perceived changes in the nature or location of a person's initial reference point, but it is not clear how framing effects might generalize to performance on dynamic decision making tasks that are characterized by high workload, time constraints, risk, or stress. A study was conducted to examine the hypothesis that framing can introduce affective components to the decision making process and can influence, either favorably (positive frame) or adversely (negative frame), the implementation and use of decision making strategies in dynamic high-workload environments. Results indicated that negative frame participants were significantly impaired in developing and employing a simple optimal decision strategy relative to a positive frame group. Discussion focuses on implications of these results for models of dynamic decision making.     

Patterns and predictors of mental health service use and mental illness among older and younger adults in the United States.

The present study examined patterns of serious mental illness (SMI), specific mental health syndromes, and service use among older (65+) and younger (18-64) adults throughout the United States, and the extent to which various factors predict SMI and the use and magnitude of mental health treatment. Despite recent developments designed to improve mental healthcare access and treatment for older adults, older individuals were found to receive outpatient mental healthcare at very low rates. Compared to younger adults, older adults were three times less likely to report receiving treatment. Although prevalence estimates for SMI and specific syndromes were markedly lower among older than younger adults, older individuals most in need of care were highly unlikely to report receiving treatment. Findings point to the importance of perceived need in mental healthcare use. Significantly, however, those older adults that made it into services typically reported benefiting considerably from treatment, at least as much as all other age groups. Several predisposing, enabling, and need factors related to mental illness and service use were identified that have important implications for how we plan for, design, and deliver mental health services to older and younger Americans.

Aging and emotional memory: The co-occurrence of neurophysiological and behavioral positivity effects.

The positivity effect is a trend for adults to increasingly process positive and/or decreasingly process negative information compared with other information with advancing age. The positivity effect has been observed with behavioral measures, such as in attention and memory tests, and with measures of neurophysiological activity, such as in amygdala activation and the late positive potential (LPP). In this study, it was investigated whether these behavioral and neurophysiological positivity effects co-occur. The electroencephalogram of younger (19–26 years) and older (65–82 years) adults was recorded while they encoded unpleasant, neutral, and pleasant pictures for retrieval in free and cued recall tests. Positivity effects occurred in the late LPP amplitude (700–1,000 ms) and in the free recall test, with negativity biases in younger adults and no biases in older adults. The occurrence of a valence bias in the LPP was substantially but nonsignificantly correlated with the occurrence of a similar valence bias in memory in the older adults. In conclusion, neurophysiological and behavioral positivity effects appear to co-occur, a finding that awaits expansion using different neurophysiological and behavioral measures.

Effects of age on cross-modal emotion perception.

Efficient navigation of our social world depends on the generation, interpretation, and combination of social signals within different sensory systems. However, the influence of healthy adult aging on multisensory integration of emotional stimuli remains poorly explored. This article comprises 2 studies that directly address issues of age differences on cross-modal emotional matching and explicit identification. The first study compared 25 younger adults (19–40 years) and 25 older adults (60–80 years) on their ability to match cross-modal congruent and incongruent emotional stimuli. The second study looked at performance of 20 younger (19–40) and 20 older adults (60–80) on explicit emotion identification when information was presented congruently in faces and voices or only in faces or in voices. In Study 1, older adults performed as well as younger adults on tasks in which congruent auditory and visual emotional information were presented concurrently, but there were age-related differences in matching incongruent cross-modal information. Results from Study 2 indicated that though older adults were impaired at identifying emotions from 1 modality (faces or voices alone), they benefited from congruent multisensory information as age differences were eliminated. The findings are discussed in relation to social, emotional, and cognitive changes with age. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Cognitive monitoring and strategy choice in younger and older adults.

Younger (24- to 39-year-old) and older (60- to 88-year-old) adults learned a list of vocabulary words; one half of the words were studied using a generally more powerful strategy (mnemonic keyword method), and one half mediated with a less powerful approach (generating semantic contexts). Before using these strategies as part of the experiment, neither younger nor older adults judged that the keyword method was more effective and neither group preferred one strategy over the other. After using the strategies and taking a test of strategically studied unfamiliar vocabulary words, the younger subjects reported accurately the relative effectiveness of the two strategies and selected the one that had worked better for them to apply to a subsequent list of vocabulary items. The older participants were not as aware of the differential potency of the strategies and did not rely as much as did the younger subjects on knowledge of strategy utility in making strategy choices. In short, metacognitive awareness of strategy effects produced by monitoring and use of metacognitive awareness in regulating strategy choice were more pronounced in the younger compared with the older sample in this study.

Age differences in forgiveness: The role of future time perspective.

This study investigated whether the age trend in forgiveness is partly attributable to age differences in time perspective. Eighty-nine younger and 91 older adults were randomized into 3 experimental conditions: time-expanded, time-limited, and neutral. They responded to hypothetical offensive scenarios and rated the degree to which they would forgive the perpetrator. Results showed that older adults were more forgiving than younger adults, but regardless of age, those in the time-limited condition were more forgiving than those in the time-expanded or the neutral condition. An Age × Time perspective interaction showed that only in older adults did a time-expanded manipulation lead to lower forgiveness than the neutral condition.

Age differences in the allocation of study time account for age differences in memory performance

How aging affects the utilization of monitoring in the allocation of study time was investigated by having adults learn paired associates during multiple study-test trials. During each trial, a subject paced the presentation of individual items and later judged the likelihood of recalling each item on the upcoming test; after all items had been studied and judged, recall occurred. For both age groups in Study 1, (1) people's judgments were highly accurate at predicting recall and (2) intraindividual correlations between judgments (or recall) on one trial, and study times on the next trial were negative, which suggests that subjects utilized monitoring to allocate study time. However, the magnitude of these correlations was less for older than for younger adults. Study 2 revealed that these differences were not due to age differences in forgetting. Results from both studies suggest that older adults do not utilize on-line monitoring to allocate study to the same degree as younger adults do, and that these differences in allocation contribute to age deficits in recall.     

Saving the best for last: How adults treat social partners of different ages.

Older adults report more positive feelings and fewer problems in their relationships than do younger adults. These positive experiences may partially reflect how people treat older adults. Social partners may treat older adults more kindly due to their sense that time remaining to interact with these older adults is limited. Younger (n = 87, age 22 to 35) and older (n = 89, age 65 to 77) participants indicated how positively they would behave (i.e., express affection, proffer respect, send sentimental cards) and what types of conflict strategies they would use in response to hypothetical negative interactions with two close social partners, a younger adult and an older adult. Multilevel models revealed that participants were more avoidant and less confrontational when interacting with older adults than when interacting with younger adults. Time perspective of the relationship partially mediated these age differences. Younger and older participants were also more likely to select sentimental cards for older partners than for younger partners. Findings build on socioemotional selectivity theory and the social input model to suggest that social partners facilitate better relationships in late life.
