RESUMO
OBJECTIVES: Preparing for old age is an adaptive behavior with positive consequences on well-being. This study examined; (a) the degree to which the importance associated with positive outcomes within specific domains of everyday functioning (e.g., social relationships, health) varies across ages and cultures; (b) the impact of importance on preparing for old age; and (c) whether the effects of importance were greater in later life. METHODS: Using data from adults aged 30-85 years in Germany (n = 623), Hong Kong (n = 317), and the United States (n = 313) collected over 5 years, we examined variations in importance ratings across age, cultures, and behavioral domains, and the extent to which age and importance predicted preparations. RESULTS: Importance ratings were found to vary with age, time of test, domains, and culture, reflecting the expected contextual effects. Importance also was a positive predictor of preparations, with the strength of prediction being somewhat greater in old age. DISCUSSION: The results provide evidence that the perceived importance of functioning within domains is affected by a number of contextual factors, including the domain of everyday function and culture. Given that importance also predicts preparations, such variation may help explain differences in preparations across contexts. In line with selective engagement theory, some support was also obtained for the prediction that older adults are more selective in engaging resources in support of preparations. Such selectivity can be viewed as an adaptive response to diminishing personal resources in later life.

Early detection of cognitive decline is essential to study mild cognitive impairment and Alzheimer's Disease in order to develop targeted interventions and prevent or stop the progression of dementia. This requires continuous and longitudinal assessment and tracking of the related physiological and behavioral changes during daily life. In this paper, we present a low cost and low power wearable system custom designed to track the trends in speech, gait, and cognitive stress while also considering the important human factor needs such as privacy and compliance. In the form factors of a wristband and waist-patch, this multimodal, multi-sensor system measures inertial signals, sound, heart rate, electrodermal activity and pulse transit time. A total power consumption of 2.6 mW without any duty cycling allows for more than 3 weeks of run time between charges when 1500 mAh batteries are used.Clinical Relevance- Much earlier detection of Alzheimer's disease and related dementias may be possible by continuous monitoring of physiological and behavioral state using application specific wearable sensors during the activities of daily life.

Age discrimination is pervasive in most societies and bears far-reaching consequences for individuals' psychological well-being. Despite that, studies that examine cross-cultural differences in age discrimination are still lacking. Likewise, whether the detrimental association between age discrimination and psychological well-being varies across contexts remains an open question. In this study, therefore, we examined cross-cultural differences in perceived experiences of age discrimination and their detrimental association with a specific indicator of psychological well-being, which is life satisfaction. The sample was drawn from the Ageing as Future study and comprised 1653 older adults (60-90 years) from the Czech Republic, Germany, Hong Kong, Taiwan, and the USA. Participants self-reported their experiences of age discrimination and their life satisfaction. Findings indicated that participants from Hong Kong and Taiwan reported experiences of perceived age discrimination more often than participants from the Czech Republic, Germany, and the USA. Furthermore, experiences of age discrimination were negatively associated with life satisfaction. Cultural context moderated this relation: We found a smaller detrimental association between perceived experiences of age discrimination and life satisfaction in Eastern cultures, that is, in contexts where such experiences were perceived to be more prevalent. These findings highlight the importance of examining age discrimination across cultures. Experiences of age discrimination are clearly undesirable in that they negatively affect psychological well-being. Our results indicate that a higher self-reported prevalence of perceived age discrimination in the samples studied weakens this negative association. We discuss these findings in terms of adaptation (versus sensitization) in response to discrimination.
RESUMO
OBJECTIVES: Past studies showed that intergenerational contact is beneficial in improving attitudes toward older people. To date, however, research on the benefits of contact with older adults focused on younger adults (intergenerational contact), overlooking the effects for older adults (contact with same-age peers). In this study, we investigated the association between contact with older adults and views of the self in old age in a domain-specific way among younger and older adults. METHODS: The sample (n = 2,356) comprised younger (39-55 years) and older (65-90 years) adults who participated in the aging as future study and were from China (Hong Kong and Taiwan), the Czech Republic, Germany, and the United States. We used moderated mediation models for data analysis. RESULTS: Contact with older adults was related to more positive views of the self in old age and this effect was mediated by more positive stereotypes of older people. These relations were stronger for older adults. Beneficial effects of contact with older adults emerged mostly in the domains of friends and leisure, but less in the family domain. DISCUSSION: Having interactions with other older adults may help favorably shape how younger adults and particularly older adults view their own aging, especially in relation to friends and leisure activities. From the perspective of older adults, having regular contacts with other older adults may increase the heterogeneity of exposure to different aging experiences, thus encouraging the formation of more differentiated stereotypes of older people and of their views of themselves in old age.

Extending research on determinants of preparations for old age across adulthood, we examined the relationship between well-being, perceived control, and preparations for old age over time, along with variation in the strength of these relationships depending on domains of functioning, cultures, and age. We analyzed longitudinal data from the Ageing as Future study assessing changes in well-being, perceived control, and preparations in four different life domains (social relations, finances, work, and health) across a five-year period collected from adults aged from 30 to 85 years in Germany (N = 623), Hong Kong (N = 317), and the USA (N = 315). Positive feelings about one's current situation predicted greater perceived control five years later, and vice versa. Also, perceived control and preparations were positively associated over time, with only a few exceptions within each domain. For example, high control beliefs were related to subsequent greater preparations and well-being within the domain of social relations and finances, with weak effects of culture. These results suggest that current well-being may promote adaptive behaviors in later life, with the accumulated effects over time. Thus, focusing on how to improve our well-being may promote engagement in preparations for old age. Our results also indicate that these relations in our model vary by contexts, highlighting the importance of variability in age-related processes.
RESUMO
Retirement is a normative life transition that liberates the individual from the external obligations of employment, being a catalyzer of leisure activity engagement. However, the individual's motivations to engage in leisure activities in the time that is gained after retirement may depend on their future self-views (i.e., views of their own ageing) as well as on their levels of preparation for age-related changes. In this study, therefore, we aim to examine longitudinal changes in levels of engagement in leisure activities that occur around the age of retirement as being influenced by views on ageing and preparation for old age. The sample consisted of 451 persons aged 50-65 years at baseline who participated in the Ageing as Future study at two time points 5 years apart. Participants were split in three age-matched groups: recently retired (in between baseline and follow-up), already retired (at baseline), and individuals who were still working (at follow-up). Findings indicated that changes in levels of leisure differed between groups. Compared to both already retired and still working participants, recently retired participants increased their levels of engagement in leisure activities. Positive views on ageing in the leisure domain (at baseline) predicted subsequent increases in activity levels but group and levels of preparation qualified this effect. A combination of positive views on ageing and preparation for age-related changes is needed for one to make use of the time that is gained with retirement, highlighting their role as determinants of behavior in response to normative life events in later life.

OBJECTIVES: Aging attitudes have important consequences on functioning in later life. A critical question concerns whether such attitudes may bias perceptions of one's own aging, with potentially negative effects on important outcomes. METHODS: Using data from adults aged 30-85 years in Germany (n = 623), Hong Kong (n = 317), and the United States (n = 313), we examined the impact of age and aging attitudes on accuracy of perceptions of change in well-being over 5 years in different domains of functioning. RESULTS: Across contexts, comparisons revealed good correspondence between retrospective reports and actual change. However, older adults and those with negative attitudes retrospectively reported less positive change over this period. Inconsistent with expectations, attitudes did not consistently bias accuracy of retrospective reports over cultures and domains of functioning, nor did age have a consistent moderating effect on the impact of attitudes on accuracy. DISCUSSION: The results highlight the complex relationship between various personal characteristics and perceptions of change in well-being, as well as the potentially insidious effects of attitudes on the accuracy of these perceptions.

The costs associated with performing a specific activity may play an important role in determining engagement, potentially impacting the willingness of older adults to engage in activities-particularly those with high demands-that may have benefits for physical and cognitive health. The present study examined changes in both objective (effort expenditure) and subjective (perceived task demands) costs associated with engagement in a cognitively challenging memory-scan task across a 5-year period in 163 older adults aged 64-81. Consistent with assumptions of selective engagement theory (SET; Hess, 2014), the effort associated with performing the task-as assessed by systolic blood pressure responses-was observed to increase over time. Subjective assessments of costs, as assessed by the National Aeronautics and Space Administration task load index (NASA TLX), were also observed to increase. In addition, the increases in both objective and subjective costs were greatest at high levels of task demands. We further found that both the effort and, to a lesser extent, perceived costs associated with performance were moderated by aging attitudes. Specifically, more positive attitudes were associated with greater effort expenditure and lower perceived costs. These findings suggest that negative attitudes about aging may have detrimental effects on perceived ability to perform challenging tasks. Given the importance of costs in determining activity participation, promoting positive aging attitudes along with more realistic perceptions of task demands may provide important means for promoting engagement in beneficial activities.

In this study, we investigated endorsement of two types of prescriptive views of aging, namely active aging (e.g., prescriptions for older adults to stay fit and healthy and to maintain an active and productive lifestyle) and altruistic disengagement (e.g., prescriptions for older adults to behave altruistically toward the younger generation by granting young people access to positions and resources). The study comprised a large international sample of middle-aged and older adults (N = 2,900), covering the age range from 40 to 90 years. Participants rated their personal endorsement of prescriptive views of active aging and altruistic disengagement targeting older adults in general (i.e., "In my personal opinion, older adults should "). Findings showed that endorsement was higher for prescriptions for active aging than for prescriptions for altruistic disengagement. Age groups in the sample differed regarding their endorsement of both prescriptive views of active aging and altruistic disengagement with older adults showing higher endorsement than middle-aged adults did. Prescriptive views of active aging and altruistic disengagement related positively to each other and to the superordinate social belief that older adults should not become a burden, which attests to their functional similarity. In contrast, prescriptive views of active aging and altruistic disengagement were associated with psychological adjustment in opposite ways, with endorsement of active aging (vs. altruistic disengagement) being related to better (vs. worse) adjustment outcomes such as life satisfaction and subjective health. Our findings highlight the internalization of prescriptive views of aging in older people and their implications for their development and well-being.
RESUMO
Healthy aging is in part dependent upon people's willingness and ability to mobilize the effort necessary to support behaviors that promote health and well-being. People may have the best information relating to health along with the best intentions to stay healthy (e.g., health-related goals), but positive outcomes will ultimately be dependent upon them actually investing the necessary effort toward using this information to achieve their goals. In addition, the influences on effort mobilization may vary as a function of physical, psychological, and social changes experienced by the individual across the life span. Building on the overall theme of this special issue, we explore the relationships between motivation, effort mobilization, and healthy aging. We begin by characterizing the relationship between motivation and effort, and identify the factors that influence effort mobilization. We then consider the factors associated specifically with aging that may influence effort mobilization (e.g., changes in cardiovascular and neural mechanisms) and, ultimately, the health and well-being of older adults. Finally, distinguishing between those influential factors that are modifiable versus intractable, we identify ways to structure situations and beliefs to optimize mobilization in support of healthy aging.

Engagement in potentially beneficial activities is assumed to be based partially on perceived costs and benefits. Mental fatigue may be one factor that affects perceived costs. We examined age differences in both chronic and situational mental fatigue, and their relation to task perceptions and engagement levels. Younger (M age = 32.6) and older (M age = 73.1) adults completed questionnaires measuring subjective mental fatigue, physical and mental health, and motivational states, along with several assessments of cognitive ability. In addition, assessments of effort expenditure (systolic blood pressure) and task difficulty were collected during performance of a cognitively demanding memory-scan task. Two components of chronic mental fatigue (CMF) relating to affect and motivation were identified. Although the structure of CMF did not vary with age, CMF was differentially predictive of engagement and appraisal levels across groups. As CMF-Affect levels increased, older adults' task-difficulty appraisals increased more than those of younger adults. In addition, CMF-Affect was positively associated with levels of engagement in the young, but negatively associated in the old as memory load increased. Older adults also exhibited higher levels of situational fatigue than did the young, as evidenced by increased levels of effort expenditure as both time on task and objective demands increased. However, little relationship existed between chronic and situational mental fatigue in either age group. These findings suggest that the affective aspect of CMF is particularly consequential in older adults, with both task appraisals and engagement levels being negatively affected when fatigue is high.

Activity that places demands on cognitive resources has positive effects on cognitive health in old age. To further understand determinants of age-group differences in participation, we examined how negative aging stereotypes and responses associated with a cognitively challenging activity influenced future willingness to engage in that activity. Sixty-nine young (20-40 years) and 80 older (63-84 years) adults performed a letter-number sequencing (LNS) task at different levels of demand for 15 min, during which systolic blood pressure responses-a measure of effort mobilization-and subjective perceptions of task demands were assessed. Approximately half the participants were primed with a negative aging stereotype prior to this task. Following the LNS task, participants completed an effort-discounting task, with resulting subjective values indicating their willingness to perform the task at each level of demand. As expected, both subjective and objective indicators of cognitive demands as well as performance were associated with future willingness to engage in a difficult task, with these effects being significantly greater for older adults. In addition, although stereotype activation influenced older adults' engagement levels in the LNS task, it did not moderate willingness. Together, the results indicate that, relative to younger adults, older adults' decisions to engage in cognitively challenging activities are disproportionately affected by their subjective perceptions of demands. Interestingly, actual engagement with the task and associated success result in reduced perceptions of difficulty and greater willingness to engage. Thus, overcoming faulty and discouraging task perceptions may promote older adults' engagement in demanding but potentially beneficial activities.

OBJECTIVES: Attributing life changes to age represents a core marker of the subjective experience of aging. The aims of our study were to investigate views on aging (VA) as origins of age-related attributions of life changes and to investigate the implications of these age-related attributions for personal control (PC) and life satisfaction (LS). METHODS: Life changes and the attribution of life changes to age were independently assessed on a large international sample of older adults (N = 2,900; age range 40-90 years) from the Ageing as Future project. The valence of VA, PC, and LS were also assessed to investigate possible determinants (VA) and consequences (PC and LS) of age-related attributions of life changes. RESULTS: Attributions to age were shown to depend on the valence of experienced life changes, with more negative changes being linked to more age-related attributions. This relation was moderated by the valence of personally held VA, with more negative VA amplifying the relation between negative life changes and age-related attributions. Age-related attributions predicted reduced PC and lower LS and were found to exacerbate the effects of negative life changes on LS, especially for the older cohorts of our sample. DISCUSSION: Our findings help to better understand what determines age-related attributions of life changes and highlight the negative consequences of attributing them to aging. Age-related attributions of change are a major factor that worsens the subjective aging experience. Methodologically, our study emphasizes the necessity to separately assess changes and their attributions to age.

Military bases are important areas for mosquito surveillance to maintain active duty combat readiness and protect training exercises. The aim of this study was to assist Camp Gruber National Guard training facility personnel to assess their mosquito community and West Nile virus (WNV) risk using biweekly sampling of 50 sites. Between May and October 2018, 10,259 adult female mosquitoes consisting of 6 genera and 26 species were collected over 662 trap-nights using 2 trap types. The most commonly collected genus was Culex (72.2% of total), followed by Psorophora (13.3%) and Aedes (10.2%). Of note, most of the medically important species were collected in the area containing troop living quarters, including 1 WNV-positive pool of Culex tarsalis. Two specimens of Aedes aegypti were collected around a vehicle storage area. While smaller in land mass size than many other active military bases in Oklahoma, the diversity of species at Camp Gruber was comparable to collections from 4 larger bases in Oklahoma. These data demonstrate the need for regular season-long mosquito monitoring of training bases to protect the health of active duty and reserve military personnel.

This article explores the influence of perceived benefits and costs on willingness to engage in social interactions in 32 young adults aged 20 to 40 years and 38 older adults aged 65 to 85 years. Results showed (1) increases in perceived benefits and importance of each relationship but decreases in perceived costs associated with increases in network centrality, (2) reduced willingness in older adults to engage with social partners for whom perceived costs outweighed benefits, and (3) perceived costs and benefits subsumed the effects of the affective qualities of social interactions. Findings support an analysis of social behavior based on the selective engagement theory (Hess, 2014), with selection effects in willingness to engage in social interactions related to perceived benefits and costs.
RESUMO
We examined young and older adults' use of descriptive information about risk (i.e., probability and expected value) in financial decision-making. In Experiment 1, participants chose between lotteries in pairs of bets that offered either two risky gains or one risky gain and one sure gain. Whereas they showed a strong and indiscriminate preference for high-probability gambles in risky-risky pairs, they selected sure options at high rates and risky options at low rates in risky-sure pairs, with slightly stronger effects in older relative to young adults due to age differences in ability. Experiment 2 involved the same task but in terms of losses. Participants, especially older adults, preferred low-probability gambles not accounted for by age differences in ability. Results suggest minimal consideration of expected value and a strong focus on probabilities in decision-making. They also suggest that cognitive ability and chronic goals differentially influence age effects depending on risk context.

OBJECTIVES: We developed brief versions of our questionnaires to assess domain-specific views on aging (age stereotypes and future self-views) and preparation for age-related changes. METHODS: The brief scales were validated in an online study with N = 301 participants aged 23-88 years. RESULTS: Mean values across domains show a differentiated picture for all 3 constructs, yielding evidence for the multidimensionality of views on aging and preparation for age-related changes. Rating profiles for the brief versions were similar to the long versions of the questionnaires, attesting to the equivalence of the brief and long scales. Within-domain correlations between the 3 constructs were also higher than between-domain correlations, further substantiating the claim of domain-specificity with regard to the predictive validity of the brief scales. DISCUSSION: The new brief versions of the scales can be recommended for a differentiated assessment of views on aging and preparation for age-related changes when short forms of measurement are required.

OBJECTIVES: Preparation for age-related changes has been shown to be beneficial to adjustment in later life. However, an understanding of the factors that influence such preparations is rather limited. This study examines whether perceived control and future-self views (FSV) influence preparations for old age, and if this influence varies across ages, domains of functioning, and cultures. METHODS: Assessments of perceived control, FSV, and preparations for old age in each of four different life domains (social relationships, finances, work, and health) were obtained from 1,813 adults (ages 35-85) from Germany, Hong Kong, and the United States. RESULTS: Future-self views partially mediated the relationship between perceived control and preparation for old age across both domains of functioning and cultures. With one exception, the association between perceived control and preparations increased with advancing age across contexts. Evidence for similar age-related moderation of the indirect effect of control through FSV was more limited. DISCUSSION: These results suggest that perceived control that is not necessarily related to aging affect FSV, which in turn influence preparing for old age. Further, our results indicate that such relationships are context- and age-specific, highlighting the importance of considering the salience and diversity of life domains and cultures.

OBJECTIVES: Personality plays a major role in determining the way people adjust to life experiences, ultimately affecting life satisfaction. Aging attitudes also impact well-being, but there is little research on whether these personality and attitudinal effects reflect the same mechanism. The purpose of this study was to examine whether aging attitudes mediate the relationship between personality and well-being across seven different domains of everyday functioning, and whether this effect depends on age. METHODS: Data from 563 adults ranging in age from 30 to 89 were used. Sociodemographic information as well as the Big Five Inventory, aging attitudes, and well-being (i.e. current self-views and life satisfaction) in seven different life domains was assessed. RESULTS: The mediating effect of aging attitudes in the relationship between personality and well-being was strong for neuroticism, conscientiousness, and agreeableness and varied across domains. Significant mediation effects were limited for openness and extraversion. Significant moderated mediations were rather limited but the effects were stronger in later life. DISCUSSION: These results suggest that personality influences aging attitudes, which in turn affect well-being. Further, our results indicate that such relationships are context-specific, suggesting that the global assessments of attitudes and well-being may not fully characterize significant aging outcomes.
