Abstract
Mind wandering is typically characterized as a failure of attentional control, yet despite age-related executive function deficits, older adults typically report less mind wandering than younger adults during cognitive tasks and in daily life. Self-reported mind wandering episodes usually result in similar behavioral detriments in younger and older adults (e.g., greater RT variability, more task errors). However, the relatively few studies investigating the neural correlates of mind wandering and aging have revealed mixed findings, possibly because they typically rely on infrequent thought probes and, therefore, few trials for neural analyses. In the current study, we propose a method to recover more task data by categorizing trials from a commonly used sustained attention to response task according to RT variability. Behavioral data (n = 49 younger; n = 40 older) revealed that compared with younger adults, older adults reported fewer mind wandering episodes, but showed similar behavioral impacts thereof. Furthermore, in both age groups, subjective reports of mind wandering predicted the more objective sorting of trials into "on-" and "off-task" according to RT variability. Using these objectively sorted trials, we investigated two commonly reported EEG measures of mind wandering (diminished P1 and P3 amplitude) in 26 younger and 24 older adults. Although the P1 did not differ between on- and off-task trials for either group, the P3 was diminished for off-task trials in both age groups (albeit significantly less in older adults) suggesting preserved perceptual but reduced higher-order processing during off-task periods in both groups.

Abstract
This study examined age differences in effort devoted to completing cognitively demanding tasks. Fifty-two younger adults ages 18-30 years (Mage = 21.19) and 57 older adults ages 61-93 years (Mage = 76.56) completed a series of memory tests. Following each test, participants rated the test's difficulty and had their blood pressure measured. Effort was indexed by systolic blood pressure response (SBP-R) with greater increases in SBP-R reflecting more effort. Multilevel modeling was used to examine age differences in the intraindividual association between trial-level subjective task difficulty and trial-level effort. Results showed that increases in task difficulty were significantly related to decreases in SBP-R for the older but not younger adults, suggesting the older adults disengaged from the tests they perceived as highly difficult. Findings support Selective Engagement Theory (Hess, 2014), which suggests the perceived cognitive costs of completing difficult tasks may reduce older adults' motivation to engage in the tasks.

Abstract
Speech motor resources may be recruited to assist challenging speech perception in younger normally hearing listeners, but the extent to which this occurs for older adult listeners is unclear. We investigated if speech motor resources are also recruited in older adults during speech perception. Specifically, we investigated if suppression of speech motor resources via sub-vocal rehearsal affects speech perception compared to non-speech motor suppression (jaw movement) and passive listening. Participants identified words in speech-shaped noise at signal-to-noise ratios (SNRs) from -16 to +16 dB in three listening conditions during which participants: (1) opened and closed their jaw (non-speech movement); (2) sub-vocally mimed 'the' (articulatory suppression); (3) produced no concurrent movement (passive listening). Data from 46 younger adults (M age = 20.17 years, SD = 1.61, 36 female) and 41 older adults (M age = 69 years, SD = 5.82, 21 female) were analysed. Linear mixed effects modelling investigated the impact of age, listening condition, and self-reported hearing ability on speech perception (d' prime). Results indicated that speech perception ability was significantly worse in older adults relative to younger adults across all listening conditions. A significant interaction between age group and listening condition indicated that younger adults showed poorer performance during articulatory suppression compared to passive listening, but older adults performed equivalently across conditions. This finding suggests that speech motor resources are less available to support speech perception in older adults, providing important insights for auditory-motor integration for speech understanding and communication in ageing.

Abstract
Academic engagement is considered one of the most essential elements to achieve educational success and decrease levels of school dropout. However, there is a need to develop reliable, practical and valid instruments that evaluate the academic engagement of adolescents taking into account their multidimensionality. The main aim of this research was to design and validate the General Scale of Academic Engagement for Spanish Adolescents that overcomes this limitation. The elaboration process began with the creation of items that are relying on the evaluation of existing literature, then the items were refined thanks to the reviews of the experts and discussion groups with adolescents. Data from 1158 students in compulsory secondary education were analyzed. The instrument's psychometric properties were determined by comprehension validity, analysis of content, reliability and construct validity. An Exploratory Factor Analysis was performed with the first sample (n = 356), while the second sample (n = 802) was used to verify the factor structure identified through Confirmatory Factor Analysis. Evidence of reliability and validity was provided for the instrument using SPSS Version 27 and SPSS AMOS. The results of the analyses resulted in a questionnaire of 17 items grouped into three factors (Cognitive, Affective-Emotional and Behavioral), and confirm that the General Scale of Academic Engagement for Spanish Adolescents (CAADE) has an adequate construct validity and reliability. In summary, this study has resulted in the development of a tool that can be utilized by educators or any institution concerned in evaluating student academic engagement, a construct that does not yet to have consensus.

Abstract
BACKGROUND Age-related declines in adult affective theory of mind (AToM) have been discovered. However, AToM measures have not accounted for emotional state complexity involved in AToM. Measures have also not accounted for different types of relationships - friends versus strangers - for which AToM is employed, which is important considering the limited social networks of aging adults. OBJECTIVE We address these issues and examine the emotion complexity, social-relatedness, and contextual relevance in AToM across adult ages (18-89 years) using a new task and two well-established measures. RESULTS The new task displayed good structural fit and internal construct validity. Overall, an age-related decline in AToM was found along with an interaction between age and emotion complexity. For all ages, AToM performance was best for complex emotions. However, as age increased, there was more rapid decline in AToM for more complex emotions than for less complex ones. Surprisingly, AToM performance for strangers was better than for social companions. CONCLUSION The findings suggest age-related AToM declines are more nuanced than previously understood given that adult age differences are related to emotional state complexity. They indicate that the emotion complexity levels of basic, complex, and self-conscious should be included in AToM assessments. Implications for AToM tasks and development are discussed.

Abstract
Older adults exposed to enriched environments (EEs) maintain relatively higher levels of cognitive function, even in the face of compromised markers of brain health. Response speed (RS) is often used as a simple proxy to measure the preservation of global cognitive function in older adults. However, it is unknown which specific selection, decision, and/or motor processes provide the most specific indices of neurocognitive health. Here, using a simple decision task with electroencephalography (EEG), we found that the efficiency with which an individual accumulates sensory evidence was a critical determinant of the extent to which RS was preserved in older adults (63% female, 37% male). Moreover, the mitigating influence of EE on age-related RS declines was most pronounced when evidence accumulation rates were shallowest. These results suggest that the phenomenon of cognitive reserve, whereby high EE individuals can better tolerate suboptimal brain health to facilitate the preservation of cognitive function, is not just applicable to neuroanatomical indicators of brain aging but can be observed in markers of neurophysiology. Our results suggest that EEG metrics of evidence accumulation may index neurocognitive vulnerability of the aging brain.Significance Statement Response speed in older adults is closely linked with trajectories of cognitive aging. Here, by recording brain activity while individuals perform a simple computer task, we identify a neural metric that is a critical determinant of response speed. Older adults exposed to greater cognitive and social stimulation throughout a lifetime could maintain faster responding, even when this neural metric was impaired. This work suggests EEG is a useful technique for interrogating how a lifetime of stimulation benefits brain health in aging.

Abstract
Life-long engagement in cognitively demanding activities may mitigate against declines in cognitive ability observed in healthy or pathological aging. However, the "mental costs" associated with completing cognitive tasks also increase with age and may be partly attributed to increases in preclinical levels of Alzheimer's disease (AD) pathology, specifically amyloid. We test whether cognitive effort costs increase in a domain-general manner among older adults, and further, whether such age-related increases in cognitive effort costs are associated with working memory (WM) capacity or amyloid burden, a signature pathology of AD. In two experiments, we administered a behavioral measure of cognitive effort costs (cognitive effort discounting) to a sample of older adults recruited from online sources (Experiment 1) or from ongoing longitudinal studies of aging and dementia (Experiment 2). Experiment 1 compared age-related differences in cognitive effort costs across two domains, WM and speech comprehension. Experiment 2 compared cognitive effort costs between a group of participants who were rated positive for amyloid relative to those with no evidence of amyloid. Results showed age-related increases in cognitive effort costs were evident in both domains. Cost estimates were highly correlated between the WM and speech comprehension tasks but did not correlate with WM capacity. In addition, older adults who were amyloid positive had higher cognitive effort costs than those who were amyloid negative. Cognitive effort costs may index a domain-general trait that consistently increases in aging. Differences in cognitive effort costs associated with amyloid burden suggest a potential neurobiological mechanism for age-related differences.

Abstract
Introduction Resilience and academic engagement have become some of the most important elements in the academic context, due to their relationships with school adjustment, the protective role against risky behaviors and the well-being of adolescents. Purpose Therefore, the objective of this study was to analyze the relationships established between the variables of resilience and academic engagement, the differences according to sex, as well as to determine the mediating role of emotional intelligence in the relationship between resilience and academic engagement in adolescence. Participants and Methods A cross-sectional descriptive study was performed. The sample consisted of 802 secondary school students, with an average age of 13.65 years (SD = 1.24) (where 50.6% were women and 49.4% men) who filled out the Connor-Davidson Resilience Scale (CD-RISC 10), the General Academic Engagement Scale for Spanish Adolescents (CAADE) and the Spanish version of the Wong Law Emotional Intelligence Scale (WLEIS-S). Results The results showed the existence of positive relationships between resilience and factors of academic engagement. Furthermore, the mediation models showed the direct effect of emotional intelligence on this relationship. On the other hand, with respect to sex, men showed significantly higher averages in resilience and emotional intelligence, with no significant differences in the variable of academic engagement. Conclusion Concluding, design of emotional intelligence intervention programs in secondary is recommended as an effective measure for promoting resilience and a positive academic trajectory.

Abstract
Decision makers are more likely to passively accept than to actively reject preselected default options. Age differences in such "default effects" have not been systematically examined, but prior research reports age-related variation in several known determinants of default effects suggesting that they may be more common in older as compared to younger adults. To address this question, a representative life span sample (N = 500; Mage = 49.90, SDage = 19.34; 51% female, 49% male; 67% non-Hispanic White) responded to a preregistered online study. Participants completed a default effect task comprising two conditions, one requiring opt-out and one requiring opt-in decisions (i.e., 15 vs. 0 preselected features each). Susceptibility to defaults was assessed as the discrepancy between the number of features selected within each condition. In addition, we collected data on known determinants of default effects (i.e., perceived endowment, endorsement, ease, experience making similar choices, importance of the choice, and affective responses to the choice). Finally, we screened demographic background, personality, socioemotional and health status, and cognitive ability. Susceptibility to default effects was evident both at the individual and the group level. Unlike hypothesized, older age did not predict greater susceptibility to defaults, and older adults were less likely to endorse determinants of default effect compliance. Of the covariates assessed, only identifying as non-Hispanic White, greater perceived endorsement, greater perceived ease, and lower perceived importance of making the right choice predicted decision makers' susceptibility to default effects. Thus, our findings suggest that susceptibility to decision defaults does not vary by age. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Abstract
People's perceptions of the mental effort required for everyday activities may drive variation in the relationships between lifestyles and cognitive ability. We asked n = 259 healthy older adults aged 60 to 70 years (90 males, 169 females) to provide a rating of the Perceived Mental Effort (PME) for each activity instance they recalled over a 48-h period as part of a time-use recall. PME was rated on a 9-point scale from "very, very low" (score of 1) to "very, very high" (score of 9). Across the entire sample, participants rated a total of 196 different activities and 17,433 activity instances. The mean PME for individual activities was 3.50 ± 1.58. PMEs varied significantly by activity domain, with highest ratings being for Work (5.48 ± 1.72) and the lowest for Self-Care (2.89 ± 0.98). In multivariate analyses, PME ratings were higher in males than females (+0.30), PMEs were higher later in the day, increased with task duration, and decreased with age (all p < 0.0001). Time-weighted average individual PMEs across the two days of recall ranged from 1.86 to 6.50, and were 0.3 units higher for males, but unrelated to age. Repeated intra-individual PME ratings for the same activity were very reliable (ICC = 0.995, mean absolute difference = 0.03 ± 0.17). PMEs show promise as a reliable measure of mental effort.

Abstract
Executive function encompasses effortful cognitive processes that are particularly susceptible to aging. Functional brain networks supporting executive function-such as the frontoparietal control network and the multiple demand system-have been extensively investigated. However, it remains unclear how structural networks facilitate and constrain the dynamics of functional networks to contribute to aging-related executive function declines. We examined whether changes in structural network modal controllability-a network's ability to facilitate effortful brain state transitions that support cognitive functions-are associated with changes in executive function cross-sectionally and longitudinally. Diffusion-weighted imaging and neuropsychological testing were conducted at two time points (Time 1: ages 56 to 66, N = 172; Time 2: ages 61 to 70, N = 267) in community-dwelling men from the Vietnam Era Twin Study of Aging. An executive function factor score was computed from six neuropsychological tasks. Structural networks constructed from white matter connectivity were used to estimate modal controllability in control network and multiple demand system. We showed that higher modal controllability in control network and multiple demand system was associated with better executive function at Time 2, after controlling for age, young adult general cognitive ability, and physical health status. Moreover, changes in executive function over a period of 5 to 6 years (Time 1-Time 2, N = 105) were associated with changes in modal controllability of the multiple demand system and weakly in the control network over the same time period. These findings suggest that changes in the ability of structural brain networks in facilitating effortful brain state transitions may be a key neural mechanism underlying aging-related executive function declines and cognitive aging.

A Novel and Selective Dopamine Transporter Inhibitor, (S)-MK-26, Promotes Hippocampal Synaptic Plasticity and Restores Effort-Related Motivational Dysfunctions. Biomolecules 2022; 12:biom12070881. [PMID: 35883437 PMCID: PMC9312958 DOI: 10.3390/biom12070881] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Revised: 06/09/2022] [Accepted: 06/21/2022] [Indexed: 11/20/2022] Open
Abstract
Dopamine (DA), the most abundant human brain catecholaminergic neurotransmitter, modulates key behavioral and neurological processes in young and senescent brains, including motricity, sleep, attention, emotion, learning and memory, and social and reward-seeking behaviors. The DA transporter (DAT) regulates transsynaptic DA levels, influencing all these processes. Compounds targeting DAT (e.g., cocaine and amphetamines) were historically used to shape mood and cognition, but these substances typically lead to severe negative side effects (tolerance, abuse, addiction, and dependence). DA/DAT signaling dysfunctions are associated with neuropsychiatric and progressive brain disorders, including Parkinson’s and Alzheimer diseases, drug addiction and dementia, resulting in devastating personal and familial concerns and high socioeconomic costs worldwide. The development of low-side-effect, new/selective medicaments with reduced abuse-liability and which ameliorate DA/DAT-related dysfunctions is therefore crucial in the fields of medicine and healthcare. Using the rat as experimental animal model, the present work describes the synthesis and pharmacological profile of (S)-MK-26, a new modafinil analogue with markedly improved potency and selectivity for DAT over parent drug. Ex vivo electrophysiology revealed significantly augmented hippocampal long-term synaptic potentiation upon acute, intraperitoneally delivered (S)-MK-26 treatment, whereas in vivo experiments in the hole-board test showed only lesser effects on reference memory performance in aged rats. However, in effort-related FR5/chow and PROG/chow feeding choice experiments, (S)-MK-26 treatment reversed the depression-like behavior induced by the dopamine-depleting drug tetrabenazine (TBZ) and increased the selection of high-effort alternatives. Moreover, in in vivo microdialysis experiments, (S)-MK-26 significantly increased extracellular DA levels in the prefrontal cortex and in nucleus accumbens core and shell. These studies highlight (S)-MK-26 as a potent enhancer of transsynaptic DA and promoter of synaptic plasticity, with predominant beneficial effects on effort-related behaviors, thus proposing therapeutic potentials for (S)-MK-26 in the treatment of low-effort exertion and motivational dysfunctions characteristic of depression and aging-related disorders.

Abstract
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.

The acute effects of mental fatigue on balance performance in healthy young and older adults - A systematic review and meta-analysis. Acta Psychol (Amst) 2022; 225:103540. [PMID: 35245722 DOI: 10.1016/j.actpsy.2022.103540] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Revised: 01/29/2022] [Accepted: 02/17/2022] [Indexed: 12/26/2022] Open
Abstract
Cognitive resources contribute to balance control. There is evidence that mental fatigue reduces cognitive resources and impairs balance performance, particularly in older adults and when balance tasks are complex, for example when trying to walk or stand while concurrently performing a secondary cognitive task. We conducted a systematic literature search in PubMed (MEDLINE), Web of Science and Google Scholar to identify eligible studies and performed a random effects meta-analysis to quantify the effects of experimentally induced mental fatigue on balance performance in healthy adults. Subgroup analyses were computed for age (healthy young vs. healthy older adults) and balance task complexity (balance tasks with high complexity vs. balance tasks with low complexity) to examine the moderating effects of these factors on fatigue-mediated balance performance. We identified 7 eligible studies with 9 study groups and 206 participants. Analysis revealed that performing a prolonged cognitive task had a small but significant effect (SMDwm = -0.38) on subsequent balance performance in healthy young and older adults. However, age- and task-related differences in balance responses to fatigue could not be confirmed statistically. Overall, aggregation of the available literature indicates that mental fatigue generally reduces balance in healthy adults. However, interactions between cognitive resource reduction, aging and balance task complexity remain elusive.

Abstract
OBJECTIVES Normal aging involves progressive prefrontal declines and impairments in executive control. This study aimed to examine the efficacy of an executive-control training focusing on working memory and inhibition, in healthy older adults, and to explore the role of individual differences in baseline capacities and motivation in explaining training gains. METHODS Forty-four healthy older adults were randomly assigned to an experimental (training executive control) or active control group (training processing speed). Participants completed six online training sessions distributed across two weeks. Transfer effects to working memory (Operation Span test), response inhibition (Stop-Signal test), processing speed (Pattern Comparison) and reasoning (Raven's Advanced Progressive Matrices and Cattell Culture Fair test) were evaluated. Furthermore, we explored individual differences in baseline capacities and assessed motivation during and after the intervention. RESULTS The experimental group, but not the active control, showed significant transfer to response inhibition. Moreover, a general compensation effect was found: older adults with lower baseline capacities achieved higher levels of training improvement. Motivation was not related to training performance. CONCLUSION Our results encourage the use of executive control training to improve cognitive functions, reveal the importance of individual differences in training-related gains, and provide further support for cognitive plasticity during healthy aging.

Abstract
Across the lifespan, learners have to tackle the challenges of learning new skills. These skills can range from abilities needed for survival, such as learning languages, learning to walk during infancy, and learning new software for a job in adulthood, to abilities related to leisure and hobbies. As the learner progresses through novice to expert stages, there are cognitive and metacognitive, motivational, and resource considerations for learning new skills. In terms of cognitive considerations, fluid and crystallized abilities as well as executive functions interact to help the learner process and retain information related to the skills. In terms of metacognitive considerations, knowing what to learn and how to learn are important for novel skill learning. In terms of motivational considerations, changes in individuals' intrinsic and extrinsic motivation throughout the lifespan impact their pursuit of novel skill learning, and declines in motivation can be buffered through the cultivation of grit, growth mindset, self-efficacy, and other personal factors. In terms of resource considerations, there are many tools that learners can use to acquire new skills, but allocation and availability of these resources differ based on life stage and socioeconomic status. Taken together, these considerations may provide learners with the best chance at acquiring new skills across the lifespan. Further research investigating these three factors, particularly among older adult learners, and their interactive effects could help increase our understanding of their impacts on skill learning and inform future cognitive interventions that can be tailored to learners' unique needs.

Abstract
OBJECTIVES The current experiment tested the causal effect of goal orientation on subjective satisfaction with performance on a cognitive task. METHODS A sample of N = 231 young, middle-aged, and older adults (21 - 79 years) completed a dot-memory task in one of three goal-orientation conditions aiming for improvement, maintenance, or avoidance of decline in performance. RESULTS Bayesian analyses showed that in all age groups goal orientation influenced actual performance, but did not affect perceived performance or performance satisfaction. Performance satisfaction was positively correlated with perceived performance, but not with actual performance. DISCUSSION The findings suggest that whether goal orientation benefits older adults' subjective well-being might depend on (a) the goal content (previous research targeted personal goals) or (b) whether it enhances their perception of the status quo (and thus reduces the discrepancy between actual and desired states). This study contributes to a better understanding of the role of goal orientation in subjective well-being across adulthood.

Abstract
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.

Abstract
Normal aging is usually accompanied by several structural and functional physiological changes of the brain, which are closely related to alterations of cognitive functions (e.g., visual short-term memory). As the average age of the population increases, it has become crucial to identify cognitive-behavioural interventions to maintain a healthy level of cognitive performance. Among a variety of approaches, the targeting of specific intrinsic alertness mechanisms has shown a solid rationale and beneficial effects in both healthy and pathological ageing. In a similar vein, the use of non-invasive transcranial electrical stimulation (tES) represents another promising approach to induce an alerting state that can produce advantages in the information processing in the brain and therefore behaviour. Here, we investigated whether time-locked bursts of tES (i.e., transcranial random noise stimulation) were effective in inducing behavioural and physiological changes, consistently with an alertness increase, in both young and older healthy adults. Namely, we expected to find a beneficial alerting effect on visual short-term memory performance as a function of stimulus perceptual salience and tES. The initial results showed that the performance of younger adults was not affected by tES, while older adults scored lower correct responses for high-salience stimuli during real tES with respect to sham stimulation. However, after including a baseline measure of subjective level of alertness in the analyses, a tES-induced memory improvement did emerge in the less alerted younger adults, while only the more alerted older adults were subject to the worsening effect by tES. We discuss these results in consideration of the evidence on critical age-related differences as well as the interaction between neurostimulation and baseline alerting mechanisms.

Abstract
BACKGROUND Personal treatment goals (PTG) are important means to tailor psychotherapy to the needs of the patient, leading to increased engagement and greater improvement in relevant outcomes. According to lifespan developmental research, motivational goals in old age differ from goals of younger people, with management of losses rather than growth becoming more prevalent. However, this study is the first to systematically investigate age-specific differences in PTGs. METHOD We used routine data from patients with major depression assessed at the beginning of outpatient cognitive behavioural therapy. Initial high-priority PTGs were assessed using the Bern Inventory of Treatment Goals (BIT-C). Older patients (≥60 years, n = 52) were matched to younger patients (<60 years, n = 52) with regard to severity of depression, number of comorbidities, gender and level of education. RESULTS Using a mixed method approach, high-priority PTGs of both age groups were focused most strongly on reducing depressive symptoms and, subsequently, anxiety. At the same time, older patients focused more strongly on PTGs related to well-being and functioning, while younger patients' emphasis was on personal growth. Furthermore, better coping with the ageing process and physical losses emerged as important PTGs for some older patients. CONCLUSION Initial PTG themes are specific to diagnosis, but also seem to differ in regard to age. Thus, it is important to develop age-sensitive measures that allow appropriate and efficient tailoring of psychotherapy to meet older patients' needs and preferences.

Abstract
Recent work suggests that most older adults who volunteer to take part in cognitive experiments are more motivated to do well than are undergraduate students. This empirical evidence is echoed by the impressions of cognitive aging researchers. We surveyed a large group (N = 88) of researchers asking about their perceptions of younger and older adults' motivation to take part in lab-based research. Not only were older adults seen as more motivated than younger adults, but researchers thought that the two groups participate for different reasons: younger adults to obtain course credit or monetary compensation, older adults to get a sense of their cognitive health, to further science, and out of curiosity. However, older adults' greater motivation to do well on cognitive tasks may leave them vulnerable to stereotype threat, the phenomenon by which individuals underperform when they are put in a position to either confirm or deny a negative stereotype about their group. In this opinion piece, we argue that most cognitive experiments, not just those designed to measure stereotype threat, likely induce some form of performance-related anxiety in older adults. This anxiety likely leads to greater task-related interference, or thoughts about how one is doing on the task, resulting in poorer performance. We discuss some of the potential implications for our understanding of neurocognitive aging.

Abstract
Engagement in cognitively demanding activities is beneficial to preserving cognitive health. Our goal was to demonstrate the utility of frequentist, Bayesian, and fiducial statistical methods for evaluating the robustness of effects in identifying factors that contribute to cognitive engagement for older adults experiencing cognitive decline. We collected a total of 504 observations across two longitudinal waves of data from 28 cognitively impaired older adults. Participants’ systolic blood pressure responsivity, an index of cognitive engagement, was continuously sampled during cognitive testing. Participants reported on physical and mental health challenges and provided hair samples to assess chronic stress at each wave. Using the three statistical paradigms, we compared results from six model testing levels and longitudinal changes in health and stress predicting changes in cognitive engagement. Findings were mostly consistent across the three paradigms, providing additional confidence in determining effects. We extend selective engagement theory to cognitive impairment, noting that health challenges and stress appear to be important moderators. Further, we emphasize the utility of the Bayesian and fiducial paradigms for use with relatively small sample sizes because they are not based on asymptotic distributions. In particular, the fiducial paradigm is a useful tool because it provides more information than p values without the need to specify prior distributions, which may unduly influence the results based on a small sample. We provide the R code used to develop and implement all models.

Abstract
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.

Abstract
The verbal identity n-back task is commonly used to assess verbal working memory (VWM) capacity. Only three studies have compared brain activation during the n-back when using auditory and visual stimuli. The earliest study, a positron emission tomography study of the 3-back, found no differences in VWM-related brain activation between n-back modalities. In contrast, two subsequent functional magnetic resonance imaging (fMRI) studies of the 2-back found that auditory VWM was associated with greater left dorsolateral prefrontal cortex (DL-PFC) activation than visual VWM, perhaps suggesting that auditory VWM requires more cognitive effort than its visual counterpart. The current study aimed to assess whether DL-PFC activation (i.e., cognitive effort) differs by VWM modality. To do this, 16 younger adults completed an auditory and visual n-back, both at four levels of VWM load. Concurrently, activation of the PFC was measured using functional near-infrared spectroscopy (fNIRS), a silent neuroimaging method. We found that DL-PFC activation increased with VWM load, but it was not affected by VWM modality or the interaction between load and modality. This supports the view that both VWM modalities require similar cognitive effort, and perhaps that previous fMRI results were an artefact of scanner noise. We also found that, across conditions, DL-PFC activation was positively correlated with reaction time. This may further support DL-PFC activation as an index of cognitive effort, and fNIRS as a method to measure it.

Abstract
BACKGROUND Dementia can negatively impact the well-being of people living with dementia and their family carers. Research suggests that music psychosocial interventions are effective, safe alternatives to pharmacological interventions for the promotion of well-being . However, evidence is limited, and research gaps remain. This study explores how a community-based group singing intervention impacts the well-being of people with early-stage dementia and their family carers. METHODS A phenomenological methodological approach was adopted. Participants engaged in a six-week group singing intervention facilitated by a music therapist in a community arts centre. Semi-structured interviews were conducted (n = 7). RESULTS Interpretative Phenomenological Analysis revealed four superordinate themes: (1) Social Connection; (2) Happiness and Rejuvenation; (3) Reconnection with the Self; and (4) Supporting the Carer-Cared-for Relationship. CONCLUSIONS Evidence of multidimensional enhancement of well-being, absence of adverse effects, and accessibility of this musical medium support the increased provision of community-based singing groups for these populations.

Abstract
Across the lifespan, the performance in problem-solving tasks varies strongly, owing to age-related variation in cognitive abilities as well as the motivation to engage in a task. Non-human primates provide an evolutionary perspective on human cognitive and motivational ageing, as they lack an insight into their own limited lifetime, and ageing trajectories are not affected by customs and societal norms. To test age-related variation in inhibitory control, cognitive flexibility and persistence, we presented Barbary macaques (Macaca sylvanus), living at La Forêt des Singes in Rocamadour (France), with three problem-solving tasks. We conducted 297 trials with 143 subjects aged 2-30 years. We found no effect of age on success and latency to succeed in the inhibitory control task. In the cognitive flexibility task, 21 out of 99 monkeys were able to switch their strategy, but there was no evidence for an effect of age. Yet, the persistence in the motivation task as well as the overall likelihood to participate in any of the tasks declined with increasing age. These results suggest that motivation declines earlier than the cognitive abilities assessed in this study, corroborating the notion that non-human primates and humans show similar changes in motivation in old age. This article is part of the theme issue 'Evolution of the primate ageing process'.

Abstract
Incentives are usually expected to increase motivation and cognitive control and to thereby improve performance. A small but growing number of studies have begun to investigate whether the effects of incentive on cognitive performance differ for younger vs. older adults. Most have used attention and cognitive control paradigms, trial-wise implementation of incentive condition, and gain incentives (reward), with only a very few investigating the effects of loss incentives. The present study takes a complementary approach: We tested younger and older adults in a working memory paradigm with loss incentives implemented session-wide (between subjects). We also included self-report measures to ask how loss incentive affected participants’ perceptions of the mental demand of the task, as well as their perceived effort, frustration, motivation, distraction, and metacognitive judgments of how well they had performed. This allowed us to test the disparate predictions of different theoretical views: the intuitive hypothesis that incentive should increase motivation and performance, the motivational shift proposal that older adults are especially motivated to avoid losses (Freund and Ebner, 2005), a heuristic “positivity effect” perspective that older adults ignore losses (Brassen et al., 2012; Williams et al., 2017), and a more nuanced view that suggests that when negative information is unavoidable and increases perceived costs, older adults may instead disengage from the situation (Charles, 2010; Hess, 2014). The results seemed most consistent with the more nuanced view of the positivity effect. While neither group showed incentive-related performance differences, both younger and older adults reported greater perceived demand and frustration under loss incentive, especially in the most challenging conditions. Loss incentive increased the accuracy of immediate metacognitive judgments, but reduced the accuracy of later, more global judgments of competency for older adults. Self-report measures suggested that the loss incentive manipulation was distracting to young adults and demotivating for older adults. The results suggest a need for caution in generalizing from existing studies to everyday life, and that additional studies parameterizing critical aspects of task design and incentive manipulation are needed to fully understand how incentives affect cognition and motivation in younger and older adults.

Abstract
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.

Abstract
Introduction: To explain motivational difficulties in schizophrenia (SZ), attention has focused on the reward system and effort-based decision-making deficits. However, according to motivational intensity theory (MIT), effort is not directly determined by reward but by task difficulty. Moreover, no studies have examined the effort perception in the SZ. Therefore, this cross-sectional study compared effort perception in SZ group with healthy controls. Method: Task difficulty was manipulated by increasing the distance covered (from 8 to 48 metres). Walking speed, perceptions of difficulty and effort were assessed for all difficulty levels. Clinical and bodyweight variables were recorded. Results: As postulated by MIT, perceived effort and difficulty increased with task difficulty in both groups. Perceived effort and difficulty were higher in the SZ group. Perceptions of effort were positively correlated with BMI in SZ, but not with clinical variables. Importantly, although SZ patients perceived the task as more effortful, walking speed was similar between groups. Conclusions: Taken together, these results suggested that individuals with SZ perceived more strongly the effort and the difficulty of the task but could mobilise more effort to complete it. This observation may explain in part the decrease in engaging in physical demanding activities in daily life in SZ.

Abstract
Biological motion perception is the ability of the visual system to perceive complex human movement patterns. The previous studies have shown a direct link between attentional abilities and performance on biological motion tasks, both of which have been shown to deteriorate with age. However, it is not known whether there is a direct link between age-related deficits in biological motion processing and attention. Here, we investigated whether age-related changes in biological motion perception are mediated by impaired attentional abilities. To assess basic biological motion performance, we asked 42 younger (M = 21 years) and 39 older adults (M = 69 years) to indicate the facing direction of point-light actions. Performance did not differ between age groups. We assessed visual spatial and selective attentional abilities, using a range of tasks: conjunctive visual search, spatial cueing, and the Stroop task. Across all tasks, older adults were significantly slower to respond and exhibited larger interference/cueing effects, compared to younger adults. To assess attentional demands in relation with biological motion perception, participants performed a biological motion search task for which they had to indicate the presence of a target point-light walker among a varied number of distracters. Older adults were slower, and generally worse than younger adults at discriminating the walkers. Correlations showed that there was no significant relationship between performance in attention tasks and biological motion processing, which indicates that age-related changes in biological motion perception are unlikely to be driven by general attentional decline.

Abstract
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.

Abstract
Higher relevance may increase older adults' engagement in cognitively demanding activities; however, whether this effect will maintain when available cognitive resources are limited? Consequently, we investigated the joint impact of task relevance and cognitive load on older and younger adults' decision search behaviors. We adopted a 2 (age: young/old) × 2 (cognitive load: without load/with load) × 2 (task relevance: high/low) mixed design. Sixty-one younger and 63 older adults completed high-relevance and low-relevance decisions. Our results revealed that older (vs. younger) adults took more time and more alternative-based search before decision-making. Both age groups sampled less information with an additional memory task. Additionally, they spent more time and effort to sample more information on high-relevance (vs. low-relevance) decisions; however, such differences disappeared when with an additional memory task. Task relevance promoted both age groups' search engagement, but this effect was subjected to their available cognitive resources.

Abstract
Abstract
Objectives
This study sought to assess how framing effects modulate age-related differences in effort-based decision-making. Consistent with the selection, optimization, and compensation (SOC) model’s loss prevention account of aging, we predicted that older adults would be more willing to select high-effort options in loss contexts than gain contexts.
Method
Older and younger adults completed the effort expenditure for rewards task (EEfRT) in either a gain or loss context. The EEfRT is an effort-based decision-making paradigm in which participants choose between a low-effort, “easy” option and a high-effort, “hard” option for several trials. The probability and value of an outcome varies on a trial-by-trial basis.
Results
The results supported our prediction and the SOC model. Older adults chose more high-effort, difficult options in loss frames than gain frames. Older adults also chose more low-effort, easy options than younger adults in gain contexts, but did not differ from younger adults in loss contexts.
Discussion
These findings demonstrate that framing effects impact older adults’ effort-based decisions. Older adults appear willing to incur a greater “cost” in the form of effort to prevent a loss than to attain a reward.

Abstract
Recently, some authors have suggested that age-related impairments in social-cognitive abilities-emotion recognition (ER) and theory of mind (ToM)-may be explained in terms of reduced motivation and effort mobilization in older adults. We examined performance on ER and ToM tasks, as well as corresponding control tasks, experimentally manipulating self-involvement. Sixty-one older adults and 57 young adults were randomly assigned to either a High or Low self-involvement condition. In the first condition, self-involvement was raised by telling participants were told that good task performance was associated with a number of positive, personally relevant social outcomes. Motivation was measured with both subjective (self-report questionnaire) and objective (systolic blood pressure reactivity-SBP-R) indices. Results showed that the self-involvement manipulation did not increase self-reported motivation, SBP-R, or task performance. Further correlation analyses focusing on individual differences in motivation did not reveal any association with performance, in either young or older adults. Notably, we found age-related decline in both ER and ToM, despite older adults having higher motivation than young adults. Overall, the present results were not consistent with previous claims that motivation affects older adults' social-cognitive performance, opening the route to potential alternative explanations.

Abstract
PurposeIntegrating the lifespan perspectives on job design and creativity/innovation, the purpose of this paper is to examine the moderating role of chronological age in the relationship between cognitive job demands (i.e. job complexity and job innovation requirements) and individual innovative work behavior (IWB).Design/methodology/approachMultilevel regression analyses are employed to analyze survey data of 336 employee–supervisor dyads from 61 departments across three organizations.FindingsResults demonstrate that age was a significant moderator of the cognitive job demands-IWB relationship. Under the condition of high job complexity, younger employees outperformed their older counterparts. Conversely, older employees attained the same level of IWB as younger colleagues when more job innovation requirements were placed upon them.Practical implicationsIWB needs to be stimulated following different paths and by making job design decisions with regards to cognitive job demands that are dependent on employee age.Originality/valueEmpirical evidence has been provided to support the lifespan perspective on job design, with a special focus given to the cognitive job demands–IWB relationship.

Abstract
Motivational incentives play an influential role in value-based decision-making and cognitive control. A compelling hypothesis in the literature suggests that the motivational value of diverse incentives are integrated in the brain into a common currency value signal that influences decision-making and behavior. To investigate whether motivational integration processes change during healthy aging, we tested older (N = 44) and younger (N = 54) adults in an innovative incentive integration task paradigm that establishes dissociable and additive effects of liquid (e.g., juice, neutral, saltwater) and monetary incentives on cognitive task performance. The results reveal that motivational incentives improve cognitive task performance in both older and younger adults, providing novel evidence demonstrating that age-related cognitive control deficits can be ameliorated with sufficient incentive motivation. Additional analyses revealed clear age-related differences in motivational integration. Younger adult task performance was modulated by both monetary and liquid incentives, whereas monetary reward effects were more gradual in older adults and more strongly impacted by trial-by-trial performance feedback. A surprising discovery was that older adults shifted attention from liquid valence toward monetary reward throughout task performance, but younger adults shifted attention from monetary reward toward integrating both monetary reward and liquid valence by the end of the task, suggesting differential strategic utilization of incentives. These data suggest that older adults may have impairments in incentive integration and employ different motivational strategies to improve cognitive task performance. The findings suggest potential candidate neural mechanisms that may serve as the locus of age-related change, providing targets for future cognitive neuroscience investigations.

Abstract
A study with young and older adults (N = 91) investigated the effect of self-involvement on stereotyping tendency and effort mobilization. We hypothesized that the impact of self-involvement varies as a function of age: increased self-involvement should lead older adults to engage in more effortful information processing and decreased stereotyping, whereas increased self-involvement should have no impact on effort mobilization and stereotyping tendency in young adults. Young and older adults read narratives under low and high-self-involvement conditions before performing a recognition test that measured their stereotyping tendency. Effort was assessed as cardiovascular responses. We found that older adults in the high-self-involvement condition presented low stereotyping tendency (similar to that of young people) in comparison to older adults in the low-self-involvement condition. Furthermore, older adults in the high-self-involvement condition had decreased high-frequency heart rate variability in comparison to the other conditions, but only during the recognition test; this suggests increased effort mobilization. These findings indicate that self-involvement decreases older adults' stereotyping tendency, possibly through effort mobilization.

Abstract
The impact of aging stereotypes on task engagement was examined. 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. Although potentially negative in the long run, elevated cardiovascular responses indicative of task engagement may represent an adaptive response to support performance.

Abstract
OBJECTIVE Recently, motivation has been found to attenuate the age-related decline in Theory of Mind (ToM) performance (i.e. faux pas recognition). However, whether or not this effect could be generalized to other ToM tasks is still unknown. In the present study, we investigated whether and how motivation could enhance older adults' performance and reduce age differences in ToM tasks (Faux Pas vs. Animation task) that differ in familiarity. METHOD Following a previous paradigm, 171 Chinese adults (87 younger adults and 84 older adults) were recruited, and we experimentally manipulated the level of perceived closeness between participants and the experimenter before administering the ToM tasks in order to enhance participants' motivation. RESULTS Results showed that, for the Faux Pas task, we replicated previous findings such that older adults under the enhanced motivation conditions performed equally well as younger adults. Conversely, for the Animation task, younger adults outperformed older adults, regardless of motivation. DISCUSSION These results indicate that motivation can enhance older adults' performance in ToM tasks, however, this beneficial effect cannot be generalized across ToM tasks.

Abstract
Engagement in cognitively demanding everyday activities has been shown to benefit cognitive health in later life. 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.

Abstract
In the present study, we examined whether age influences the effects of mental fatigue on task performance, and if we could validate the use of measures based on typing behavior as an index of the effects of mental fatigue on different aspects of cognition. Young (N = 24, 18–30 years) and middle-aged (N = 24, 50–67 years) participants performed a typewriting task and a mouse targeting task for 120 min. At the beginning and at the end of the experiment the level of subjective fatigue was assessed. During task performance measures based on typing behavior and EEG were recorded. Results showed that subjective fatigue increased over the experiment in both the young and the middle-aged group. Typing speed decreased with time-on-task (ToT) in both age groups, reflected in larger general interkey intervals and in an increase in typing time. In addition, typing accuracy decreased with ToT in the young group, however, not in the middle-aged group, reflected by an increase in typing errors. Moreover, the young group used the backspace key more often with ToT due to delayed error-correction, reflected in larger backspace sequences, resulting in larger interkey intervals and increased typing time. This effect was absent in the middle-aged group. In the young group, the P3 brain potential amplitude decreased over the experiment, which was related to an increase in typing time, longer general interkey intervals, and an increase in typing errors, suggesting that decreased task engagement was related to less efficient typewriting, at least in the young group. These results indicate that measures based on typing behavior could give information about the process of mental fatigue, and in addition suggest that age influences the effect of mental fatigue on typewriting. More specifically, younger adults more often adopt a strategy that emphasizes speed, while middle-aged adults act more error-aversive than younger adults.

Abstract
Cognitive control refers to the ability to regulate cognitive processing according to the tasks at hand, especially when these are demanding. It includes maintaining and updating relevant information in working memory, inhibiting irrelevant information, and flexibly switching between tasks. Performance monitoring denotes the processing of feedback from the environment and the detection of errors or other unexpected events and signals when cognitive control needs to be exerted. These two aspects of behavioral adaptation critically rely on the integrity of the frontal lobes, which are known to show pronounced age-related performance decrements. By contrast, there is evidence that processing of rewards remains relatively intact across the adult lifespan. Hence, motivation may play an important role in modulating or even counteracting age-related changes in cognitive control functions. To answer this question, neuroscientific data can be particularly useful to uncover potential underlying mechanisms beyond behavioral outcome. The aims of this article are twofold: First, to review and systematize the extant literature on how motivational incentives can modulate performance monitoring and cognitive control in young and older adults. Second, to demonstrate that important pieces of empirical data are currently missing for the evaluation of this central question, specifically in old age. Hence, we would like to stimulate further research uncovering potential mechanisms underlying motivation-cognition interactions in young and in particular in older adults and investigating whether or not those can help to ameliorate age-related impairments.

Abstract
The goal of this research was to examine the linkage between personal resources, intrinsic motivation, and participation in everyday activities. It was hypothesized the reductions in resources in later life will be associated with reduced motivation to engage in cognitively demanding activities, leading to reduction in participation in such activities in everyday life. To test this, we utilized data from the 2010 and 2012 waves of the Health and Retirement Survey. 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.

Abstract
Engagement in cognitively demanding activities has a positive impact on cognitive health in older adults. Previous work, however, has suggested that the costs associated with engagement increase in later life and influence motivation. We examined how subjective perceptions of these costs varied with age and influenced task engagement. The following questions were of specific interest: (a) Are there age differences in subjective perceptions of cognitive costs? (b) What is the impact of these perceptions on engagement? 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. We found that age was associated with an increase in the perceptions of cognitive costs, and that these subjective perceptions had a stronger impact on older adults' engagement than on that of younger adults. More important, this impact was specific to subjective perceptions of cognitive costs. The results provide further support for the hypothesis that increased costs associated with cognitive engagement influence older adults' willingness to engage cognitive resources, and that these costs in part reflect subjective perceptions that are independent of objective task demands.

Abstract
Our objective was to identify the physiological measures that are sensitive to assessing cognitive workload across the spectrum of cognitive impairments. Three database searches were conducted: PubMed, PsychINFO, and Web of Science. Studies from the last decade that used physiological measures of cognitive workload in older adults (mean age >65 years-old) were reviewed. The cognitive workload of healthy older individuals was compared with the cognitive workload of younger adults, patients with mild cognitive impairment (MCI), and patients with Alzheimer's diseases (AD). The most common measures of cognitive workload included: electroencephalography, magnetoencephalography, functional magnetic resonance imaging, pupillometry, and heart rate variability. These physiological measures consistently showed greater cognitive workload in healthy older adults compared to younger adults when performing the same task. The same was observed in patients with MCI compared to healthy older adults. Behavioral performance declined when the available cognitive resources became insufficient to cope with the cognitive demands of a task, such as in AD. These findings may have implications for clinical practice and future cognitive interventions.
