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.

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.

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.}, journal={ACTA PSYCHOLOGICA}, author={Couto, M.

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 (Mage = 32.6) and older (Mage = 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.}, number={2}, journal={MOTIVATION SCIENCE}, author={Hess, Thomas M. and Knight, Rebekah C.}, year={2021}, month={Jun}, pages={122–132} }

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.

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.}, journal={JOURNALS OF GERONTOLOGY SERIES B-PSYCHOLOGICAL SCIENCES AND SOCIAL SCIENCES}, author={Hess, Thomas M. and Freund, Alexandra M. and Tobler, Philippe N.}, year={2021}, month={Oct}, pages={S135–S144} }

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.

Older adults (N = 144, ages 65 to 85) were exposed to primes designed to activate positive or negative stereotypes about aging, with half of the individuals in each stereotype group also assigned to a high-accountability condition to enhance motivation. Participants performed a memory-scan task comprising 2 levels of demands (memory sets of 4 or 7 items), with 2 blocks (5 min each) at each level. Systolic blood pressure recorded throughout the task was used to monitor engagement levels. High accountability was associated with greater engagement at the highest level of task demands. Negative stereotype activation also resulted in elevated engagement levels, but only during the initial trial blocks in the high-accountability condition. Lowest levels of engagement were associated with low accountability, with no difference between stereotype conditions. An analogous differential analysis on these same data using need for cognition and attitudes toward aging as measures of motivation and stereotypes revealed similar trends. Specifically, negative aging attitudes were associated with elevated levels of engagement only in individuals who were high in intrinsic motivation, with the effects greatest at the highest levels of task demands. The results provide a more nuanced perspective on the impact of negative aging stereotypes than suggested in previous research, with the impact on behavior moderated by situational and personal factors associated with motivation.

However, the underlying mechanism involved in this phenomenon is unclear. In the present study, we aimed to identify this mechanism and disentangle mood and self-perceptions as potential personal resources. In Study 1, young and older adults completed either a positive or negative mood manipulation task, or a health manipulation task designed to accentuate positive or negative perceptions of one's health-related behaviors. Participants then selected three of six health-related articles to read based on their headlines, half of which were positively worded and half of which were negative, but offered self-corrective information. Participants in the positive health condition selected more negative health-related articles to read than those in the negative health condition, with the effect being specific to older adults. Simple manipulations of mood had no effect on article selection, suggesting that older adults used their positive self-perceptions as a resource for considering negative information. In addition, endorsement of information goals mediated the relationship between manipulated health behavior perceptions and article selections for both young and older adults. Results from Study 2 demonstrate that effects are specific to situations with high-informative versus low-informative content. Our findings suggest that older adults' willingness to focus on negative self-relevant information is bolstered by enhancing self-perceptions of self within the domain of interest.

However, the results are mixed showing either more positive views in Asia, no difference at all, or even more positive views in Western countries. A potential moderator of country differences that might explain some of the heterogeneity is the fact that views on aging differ in their content and valence depending on life domains such as health versus family relations. Therefore, our aim was to systematically address domain-specific views on aging in a cross-national study, also considering that cross-national differences are age group-specific. We examined differences in views on aging between China, the United States, and Germany in eight life domains using samples with a broad age range. For most of the domains, cross-national differences indicated more negative views on aging in China compared with the Western countries and more positive views among the American compared with the German participants. Intriguingly, the differences between China and the United States or Germany were absent or even reversed in the domains friends, personality, and finances. Cross-national differences also varied by age group. Our results show that explanations of cross-national differences in views of aging probably do not apply uniformly across all life domains or age groups. They underline the importance of acknowledging the domain-specific nature of views on aging in cross-national research.

We used structural equation modeling to construct latent factors associated with health resources, cognitive resources, and intrinsic motivation. Cognitive and health resources were positively associated with intrinsic motivation, which in turn partially mediated the association between these resources and engagement in cognitively demanding everyday activities. Some variation in the fit of the model was observed across sexes, and the predictive power of the model was somewhat attenuated in the oldest old (ages 81+). The results support expectations derived from Selective Engagement Theory (Hess, 2014), which argues that increases in the costs associated with cognitive activity in later life negatively affects the motivation to engage in these potentially beneficial activities.}, number={1}, journal={Motivation Science}, publisher={American Psychological Association (APA)}, author={Queen, Tara L. and Hess, Thomas M.}, year={2018}, month={Mar}, pages={26–38} }

However, far fewer studies have examined how memory is influenced by emotion related to social and political issues (e.g., a proposal for large changes in taxation policy), which clearly vary across individuals. In order to investigate the neural substrates of affective and mnemonic processes associated with personal opinions, we employed an fMRI task wherein participants rated the intensity of agreement/disagreement to sociopolitical belief statements paired with neural face pictures. Following the rating phase, participants performed an associative recognition test in which they distinguished identical versus recombined face-statement pairs. The study yielded three main findings: behaviorally, the intensity of agreement ratings was linked to greater subjective emotional arousal as well as enhanced high-confidence subsequent memory. Neurally, statements that elicited strong (vs. weak) agreement or disagreement were associated with greater activation of the amygdala. Finally, a subsequent memory analysis showed that the behavioral memory advantage for statements generating stronger ratings was dependent on the medial prefrontal cortex (mPFC). Together, these results both underscore consistencies in neural systems supporting emotional arousal and suggest a modulation of arousal-related encoding mechanisms when emotion is contingent on referencing personal beliefs.}, number={2}, journal={COGNITIVE AFFECTIVE & BEHAVIORAL NEUROSCIENCE}, author={Wing, Erik A. and Iyengar, Vijeth and Hess, Thomas M. and LaBar, Kevin S. and Huettel, Scott A. and Cabeza, Roberto}, year={2018}, month={Apr}, pages={216–231} }

We investigated the factors that influence engagement, with specific interest in determining the extent to which the costs of engaging cognitive resources are associated with intrinsic motivation and, ultimately, participation in everyday activities. Older adults (N = 153) aged from 65 to 81 years completed a challenging cognitive task, with the costs of cognitive engagement-operationalized as the effort required to maintain performance-assessed using systolic blood pressure responses (SBP-R). We also assessed participation in everyday activities using both 2-year retrospective reports and five daily reports over a 5-week period. Structural models revealed that lower levels of costs were associated with more positive attitudes about aging, which in turn were associated with higher levels of intrinsic motivation. Motivation was subsequently predictive of everyday activity engagement, with the effect being specific to those activities thought to place demands on cognitive resources. The measure of engagement had minimal impact on the nature of the observed effects, suggesting that the retrospective and weekly assessments were tapping into similar constructs. Taken together, the results are consistent with expectations derived from Selective Engagement Theory (Hess, 2014), which argues that engagement in demanding activities is related to the cost associated with such engagement, which in turn leads to selective participation through changes in motivation.

Variations in approach and avoidance responses to individual images were also examined, along with age differences in their relationship to memory performance.In Experiment 1, young (22-43 years) and older (65-85 years) adults recalled positive and negative social scenes that were high or low in arousal. In Experiment 2, young (20-40 years) and older (65-83 years) adults viewed and recalled the same scenes under instructions designed to alter arousal, and approach and avoidance ratings for each image were recorded.In Experiment 1, age differences in recall were confined to high-arousal, negative images, with young adults exhibiting superior memory relative to older adults. There was no evidence of an age-related positivity effect for low-arousal social scenes. This result was replicated in Experiment 2, but distancing instructions minimized the age difference in recall for high-arousal, negative images. Approach and avoidance ratings differentially predicted recall across age groups, with stronger associations in the young.The results are consistent with emerging evidence demonstrating that valence-based biases associated with aging (e.g., positivity effect) are specific to the context and stimulus characteristics.

Using data from the Aging as Future project, the authors examined the degree to which views of aging influence subjective age and how this influence varies across cultures and domains of everyday functioning. Using data from 1,877 adults aged from 30 to 95 years of age collected in China, Germany, and the United States, they assessed how general attitudes about aging and perceptions of oneself as an older adult influenced subjective age estimates in 8 different domains of functioning. More positive attitudes about aging were associated with older subjective ages, whereas more positive views of self in old age were associated with younger subjective age. It is hypothesized that these effects are reflective of social-comparison processes and self-protective mechanisms. These influences varied considerably over contexts, with views of aging having a greater impact in domains associated with stronger negative stereotypes of aging (e.g., health) compared to those with more positive ones (e.g., family). Culture also moderated the impact of aging views in terms of the strength of prediction, direction of effect, and age of greatest influence, presumably due to cultural differences in the salience and strength of aging-related belief systems across contexts. The results illustrate the contextual sensitivity of subjective age and highlight the role played by an individual's views of old age-both in general and regarding oneself-in determining their own experience of aging.

We tested 39 older (ages 65-84) and 37 younger (20-42) adults on a working memory task. Systolic blood pressure responsivity (SBP-R; reflective of effort) and subjective perceptions of task difficulty were assessed.

More important, this impact was specific to subjective perceptions of cognitive costs.

Each participant answered ten discrete choice questions presenting two hypothetical tests comprised of four attributes: testing procedure, mortality reduction, test frequency, and complications. DCE responses were used to estimate each participant's most important attribute and to simulate their preferred test among three existing CRC-screening tests. For each individual, we compared the DCE-derived attributes to directly selected attributes, and the DCE-derived preferred test to a directly selected unlabeled test.Older adults do not overwhelmingly value any one CRC-screening test attribute or prefer one type of CRC-screening test over other tests. However, small absolute DCE-derived preferences for the testing procedure attribute and for sigmoidoscopy-equivalent screening tests were revealed.

I further argue that these costs result in older adults being increasingly selective in the engagement of cognitive resources in response to these declines. This selectivity is reflected in (a) a reduction in the intrinsic motivation to engage in cognitively demanding activities, which, in part, accounts for general reductions in engagement in such activities, and (b) greater sensitivity to the self-related implications of a given task. Both processes are adaptive if viewed in terms of resource conservation, but the former may also be maladaptive to the extent that it results in older adults restricting participation in cognitively demanding activities that could ultimately benefit cognitive health.

Similarly, adults of all ages used comparable decision strategies and adapted their strategies to the demands of the task. We also examined decision outcomes in relation to participants' preferences. Overall, it seems that older adults utilize simpler sets of information primarily reflecting the most valued attributes in making their choice. The results of this study suggest that older adults are adaptive in their approach to decision making and that this ability may benefit from accrued knowledge and experience.}, number={4}, journal={PSYCHOLOGY AND AGING}, publisher={American Psychological Association (APA)}, author={Queen, Tara L. and Hess, Thomas M. and Ennis, Gilda E. and Dowd, Keith and Gruehn, Daniel}, year={2012}, month={Dec}, pages={817–824} }

Older adults exhibited a higher likelihood than young adults of falsely identifying misinformation as having occurred in the events. Consistent with expectations, strength of the misinformation effect was positively associated with dominant mood, and controlling for mood eliminated any age effects. Also, motivation to engage in complex cognitive activity was negatively associated with susceptibility to misinformation, and susceptibility was stronger for negative than for positive events.

In line with a social expertise framework, middle-aged and older adults were more sensitive to trait-diagnostic behavioral information than were younger adults. Relative to younger adults, older adults paid more attention to negative than to positive information when it related to morality traits. Increasing the salience of the social context, and presumably activating socioemotional goals, did not alter this pattern of performance. In contrast, when more global social evaluations were examined (e.g., suitability as a social partner), older adults were less likely than younger or middle-aged adults to adjust their evaluations in response to situational goals. Consistent with a heightened focus on socioemotional goals, older adults' judgments were more consistently influenced by their attributions of traits that would likely impact the affective outcomes associated with interpersonal interactions.

When only accurate participants were considered, decision making was best when there was congruence between the nature of the information and the thought condition. Thus, unconscious thought was more appropriate when participants relied on intuitive rather than deliberative processing to make their decision, whereas the converse was true with conscious thought.

Consistent with previous research, middle-aged adults were less prone to the fundamental attribution error than were young and older adults. This was evidenced by their reduced tendency to make attitude attributions in the no-choice condition relative to the choice condition. Although high levels of both cognitive and attributional complexity were associated with reductions in attributional bias, complexity did not systematically account for the between-age-group differences in performance. It is suggested that the observed pattern of age effects is related to variations in both cognitive complexity and cognitive resources.}, number={4}, journal={JOURNALS OF GERONTOLOGY SERIES B-PSYCHOLOGICAL SCIENCES AND SOCIAL SCIENCES}, author={Follett, KJ and Hess, TM}, year={2002}, month={Jul}, pages={P312–P323} }

Thompson, M.E. Naccarato, & K. Parker, 1989). The results of a series of confirmatory factor analyses indicated that the two intercorrelated-factor structure of the PNS scale held up well across individuals aged 21 to 85, validating its use for the examination of ageing effects. Structural equation modelling analyses found that ageing was associated with lower levels of physical health and cognitive skill, which in turn were related to higher PNS scores. It was also found, however, that the impact of reductions in these resources on need for structure were counteracted by high levels of social activity and emotional health. The argument is made that ageing-related changes in personal resources impact everyday behaviour through changes in motivation, such as need for structure.}, number={6}, journal={INTERNATIONAL JOURNAL OF BEHAVIORAL DEVELOPMENT}, author={Hess, TM}, year={2001}, month={Nov}, pages={482–490} }

 @article{hess_waters_bolstad_2000, title={Motivational and cognitive influences on affective priming in adulthood}, volume={55}, ISSN={["1079-5014"]}, DOI={10.1093/geronb/55.4.P193}, abstractNote={This research examined age differences in the impact of affective primes on judgments about neutral stimuli. When participants were unaware that the primes had been presented, age differences were nonexistent, with individuals of all ages producing likability judgments consistent with the valence of the prime. In contrast, when awareness of the primes was maximized, prime influences were virtually nonexistent in the youngest participants, but prime influences increased with participants' age. In addition, the impact of the primes was differentially affected by an individual's need for simple structure. Need for structure did not influence the performance of young and middle-aged participants, but prime effects increased with need in the oldest participants. It is argued that the stronger predictive validity of need for structure with age is due to aging-related changes in personal resources (both social and cognitive) and/or a closer mapping of individual characteristics onto need with age. Regardless of source, the results argue for closer consideration of motivational factors in determining age differences in performance.}, number={4}, journal={JOURNALS OF GERONTOLOGY SERIES B-PSYCHOLOGICAL SCIENCES AND SOCIAL SCIENCES}, author={Hess, TM and Waters, SJ and Bolstad, CA}, year={2000}, month={Jul}, pages={P193–P204} }

Three experiments were conducted in which the ability of different-aged adults to appropriately use category-based versus attribute-based information in making affective judgments was examined. Contrary to expectations, we found that performance was minimally related to age or to working memory efficiency. Adults of all ages made affective judgments based on category information when such information resulted in appropriate inferences, whereas attribute-based information was used when category-based inferences were inaccurate. We interpret these results to be consistent with the hypothesis that the processing of evaluative information occurs at a preconscious level with little drain on processing resources.}, number={1}, journal={AGING NEUROPSYCHOLOGY AND COGNITION}, author={Hess, TM and Bolstad, CA}, year={1998}, month={Mar}, pages={27–42} }
