Previous research has identified a divergent trajectory for the aging brain, characterized by declines in cognition and preservation in emotional processing. According to the socioemotional selectivity theory, reduced time horizons in later life cause a motivational shift to prioritize emotional goals, such as positive well-being. In service of these goals, older adults devote more cognitive effort to attend to and remember positive information; however, whether they can exert control over such information once it enters memory is not well understood. The primary aim of this dissertation was thus to examine age-related changes in cognitive control of emotional memory including its underlying metacognitive and neural components. In three experiments, young and older adults completed a cue- or value-based version of the item-directed forgetting task for positive, negative, and neutral words. Results consistently demonstrated that young and older adults could strategically control encoding of emotional information, by prioritizing relevant over irrelevant words in memory. This was evident when encoding was directed by to-be-remembered (TBR) or to-be-forgotten (TBF) cues as well as by numeric points that signaled a gain or loss of value (+10 vs. -10). Extending previous research on metacognition and aging, results indicated age invariance in prospective judgments of learning made during the encoding of TBR and TBF words that varied in emotion. In contrast, age groups differed when retrospectively monitoring the source of words. Whereas young adults’ source monitoring was not influenced by emotion or cues, older adults tended to attribute positive items to sources that were higher in value for memory (TBR or +10 cues), consistent with an age-related bias to prioritize positivity. Finally, age differences in event-related potentials underlying encoding of TBR and TBF words provided evidence that older adults may recruit additional resources in frontal regions of the brain to facilitate task performance. Moreover, in line with behavioural results, the ERP signatures of directed forgetting were not modulated by emotion. Altogether, this dissertation demonstrates that cognitive control over emotional memory is intact in later life; however, it highlights important age differences in the metacognitive and neural correlates of this ability.

Background: Social status is the standing of a person or group in the social hierarchy, and is perceived to change across the life span from low social status in early life, to peak in midlife, and to a decline thereafter. As threats to subjective social status are known to be detrimental to individuals’ health, it is important to better understand how older adults perceive themselves and others in terms of age-related social status. Objective: We examined status ambivalence – the potential discrepancy between how older adults’ perceive social status for themselves compared to older adults in general. Method: Study 1 used qualitative data from 37 semi-structured interviews with older adults to assess perceptions of social status. Study 2 used quantitative survey data from 114 older adults who completed explicit and implicit measures of social status. Results: Study 1 (n = 37, meanage = 71.72, SDage = 5.69; 81.1% women) provided preliminary evidence for status ambivalence such that older adults reported unequivocal low social status for other older adults but a more ambivalent perception of their own social status. Study 2 (n = 114, meanage = 64.32, SDage = 8.98, 57.9% women) compared implicit and explicit measures of social status revealing that older adults consistently perceive older adults to have low social status but again show a more ambivalent perception of their own social status. Conclusion: We discuss status ambivalence as a potential protective mechanism in the context of negative societal perceptions of age-related social status that may be important for well-being in later life.

Abstract There has been a long tradition of wayfinding and orienteering studies in humans but these have mostly neglected possible age-related differences in navigation. This field of inquiry is experiencing something of a resurgence of interest due to the development of VR technology which has brought the systematic study of large scale navigation into the laboratory and into the MRI scanning environment. Empirical studies to date identify navigation as an aspect of cognition that is vulnerable to the aging process. Functional and structural neuroimaging studies in humans suggest that age-related changes in the brain’s “navigation circuit” may underlie these behavioral age differences. Older adults also adopt unique spatial strategies and knowledge of these strategy preferences could enlighten both basic science research in spatial cognition and also inform the development of age-specific technological assistance that may extend functional independence of older adults into later life.

Abstract In 2016, catastrophic flooding destroyed homes and property across south Louisiana. This study is part of a larger program of research that addresses the role of prior hurricane and flood experiences on current health and well-being in later life. Participants were predominately middle-aged and older adults who varied in current and prior severe weather experiences (M age=49.6 years, age range 18-88 years). All were tested during the immediate aftermath of the 2016 flood (Wave 1; N=223) and most participated in a follow-up assessment 9 (+/- 3) months later (Wave 2; N=202). Cherry et al. (2021) reported that greater flood stressors at Wave 1, such as displacement, flood-related losses, and damage to homes and property, were associated with more symptoms of post-traumatic stress disorder (PTSD). In this study, we tested the hypothesis that age, religiosity, and perceived social support would be positively associated with post-flood resilience at the Wave 2 follow-up. Results indicated that age was positively associated with religiosity and resilience, and negatively correlated with symptoms of PTSD. Additionally, faith community involvement, non-organizational religiosity, and religious beliefs and practices were all significantly correlated with post-flood resilience. Perceived social support was positively associated with resilience, and inversely correlated with PTSD symptoms. These data suggest that religiosity and perceived social support are valuable resources that foster post-disaster resilience among middle aged and older adults. Implications of these data for current views on age-related strengths and vulnerabilities after severe weather events are discussed.

Abstract Background and Objectives Scholars argue that volunteering enhances social, physical, and cognitive activities that are increasingly valued as people age, which in turn improves older adults’ well-being via a host of psychosocial and neurobiological mechanisms. This study explicitly tested older adults’ self-perceptions of aging as a mechanism underlying the mental health benefits of volunteering. Research Design and Methods Using 2-wave data from the Health and Retirement Study (2008/2010 for Wave 1 and 2012/2014 for Wave 2), we analyzed reports from a pooled sample of older adults aged 65 or older (N = 9,017). Participants reported on demographic characteristics, volunteer work (did not volunteer, 1–99 h/year, 100+ h/year), self-perceptions of aging, and depressive symptoms. We estimated an autoregressive cross-lagged panel model. Results Volunteering for 100 h or more per year was associated with older adults’ more positive and less negative self-perceptions of aging in the subsequent wave (i.e., 4 years later), which in turn predicted fewer depressive symptoms. Discussion and Implications This study suggests the promising role of volunteering in shaping older adults’ self-perceptions of aging on a sustained basis and refines our understanding of the benefits volunteering brings. Findings shed light on future interventions aimed at improving older adults’ adjustment to age-related changes and lessening ageism in society.

Adaptive Consequences

Abstract This study explored the coping strategies and social comparisons used by older adults on different loneliness trajectories (decreased loneliness, stable loneliness and degenerating loneliness). The adaptive consequences of social comparison in later life are recognised as an important strategy for preserving life satisfaction regardless of age-related losses. Coping strategies are also important in managing loneliness. Narrative interviews were conducted with lonely older adults (N = 11) who had participated in Wave One of the Maintaining Function and Well-being in Later Life Study Wales (CFAS Wales). The study found key differences in the coping strategies employed by older adults on different loneliness trajectories. Differences in coping styles between those who reported decreased loneliness and those who were chronically lonely stemmed from perceptions as to whether loneliness was modifiable or not. Different types of social comparison were also found to modulate the loneliness experience. The findings indicate that higher-order strategies (problem, emotional and meaning focused) are not distinct entities but are part of a dynamic process. The management of loneliness in later life may be dependent on several factors, including older adults’ interpretations of the cause of loneliness. These interpretations will have implications for interventions aimed at alleviating chronic loneliness, where the focus may have to be on changing older adult's perceptions of unmodifiable loneliness.

Updating prior information with new information in accordance with Bayesian principles is a difficult task. Younger adult decision makers deviate from Bayes’ theorem by either overweighting prior information (i.e., using a conservatism heuristic) or overweighting new information (i.e., using a representativeness heuristic) on decision tasks without feedback. Similar to younger adults, older adults make decisions that require belief updating. Given agerelated decrements in cognitive control, older adults may be at a disadvantage compared with younger adults when updating beliefs. Prior research shows no age differences when making decisions under risk, however older adults perform worse than younger adults when making decisions under ambiguity. Currently it is unknown how older adults use heuristics when updating beliefs about risk and ambiguous information compared with younger adults. The primary aim of this dissertation was to examine age-related differences in the use of heuristics during belief updating, as well as the cognitive processes and neural correlates that underpin behaviour. In three experiments, younger and older adults completed a belief updating task with and without feedback using an urn-ball paradigm. The main results showed that both younger and older adults committed the representativeness error more than the conservatism error, with no age differences observed when updating beliefs without feedback but with younger adults updating beliefs more accurately than older adults with feedback. Further, age differences in the neural correlates that underlie belief updating showed evidence that older adults recruit additional resources in frontal regions of the brain to facilitate performance compared with younger adults. Event-related potentials showed evidence of cognitive control in response to conflicting information in both age groups, but a diminished neural response to feedback in older compared with younger adults. Additionally, while younger adults were not influenced by ambiguous information, older adults avoided committing the representativeness error only when new information was ambiguous. Last, individual differences in numeracy and cognitive reflection, but not thinking disposition, modulated belief updating performance. Together, the results show that younger and older adults can learn to update beliefs with feedback but with younger adults learning to a greater degree than older adults, especially when information is ambiguous.

AbstractDevelopmental theories suggest age-related changes in the structure of affect. Paradoxically, the internal structure of the Positive and Negative Affect Schedule (PANAS; Watson, Clark, & Tellegen, 1988) has not been tested in Spanish older adults by means of confirmatory factor analysis (CFA) despite it is the most widely used measure of emotional well-being in later life. The aim of this study was to examine competing models of the internal structure of the Spanish version of the PANAS, its measurement invariance, reliability, and external validity. Participants were a representative sample of 585 community-dwelling people aged 60 and over, who also completed depression, loneliness and life satisfaction measures. Results showed that the orthogonal two-factor model with correlated errors (RMSEA = .057, 90% CI [.051, .063], SRMR = .084, CFI = .97, NNFI = .97) was the best fitting solution. Measurement invariance analyses confirmed that the two-independent factor structure can be used across young-old and very old people, as well as in both males and females. It showed good reliability (PA: α = .93, NA: α = .83), criterion, convergent and discriminant validity (p < .01). Our discussion highlights the role of age and culture in the experience and expression of emotions.

Studies investigating age-related positivity effects during facial emotion processing have yielded contradictory results. The present study aimed to elucidate the mechanisms of cognitive control during attentional processing of emotional faces among older adults. We used go/no-go detection tasks combined with event-related potentials and source localization to examine the effects of response inhibition on age-related positivity effects. Data were obtained from 23 older and 23 younger healthy participants. Behavioral results showed that the discriminability index (d') of older adults on fear trials was significantly greater than that of younger adults [t(44)=2.37, p=0.024, Cohen’s d=0.70], whereas an opposite pattern was found in happy trials [t(44)=2.56, p=0.014, Cohen’s d=0.75]. The electroencephalography results on the amplitude of the N170 at the left electrode positions showed that the fear-neutral face pairs were larger than the happy-neutral ones for the younger adults [t(22)=2.32, p=0.030, Cohen’s d=0.48]; the older group’s right hemisphere presented similar tendency, although the results were not statistically significant [t(22)=1.97, p=0.061, Cohen’s d=0.41]. Further, the brain activity of the two hemispheres in older adults showed asymmetrical decrement. Our study demonstrated that the age-related “positivity effect” was not observed owing to the depletion of available cognitive resources at the early attentional stage. Moreover, bilateral activation of the two hemispheres may be important signals of normal aging.

Abstract Evidence suggests that age differences in associative memory are attenuated for associations that are consistent with prior knowledge. Such knowledge structures have traditionally been associated with the default network (DN), which also shows reduced modulation with age. In the present study, we investigated whether DN activity and connectivity patterns could account for this age-related effect. Younger and older adults underwent functional magnetic resonance imaging as they learned realistic and unrealistic prices of common grocery items. Both groups showed greater activity in the DN during the encoding of realistic, relative to unrealistic, prices. Moreover, DN activity at encoding and retrieval and its connectivity with an attention control network at encoding were associated with enhanced memory for realistic prices. Finally, older adults showed overactivation of control regions during retrieval of realistic prices relative to younger adults. Our findings suggest that DN activity and connectivity patterns (traditionally viewed as indicators of cognitive failure with age), and additional recruitment of control regions, might underlie older adults’ enhanced memory for meaningful associations.
