Earlier theoretical frameworks of successful aging (SA) included either objective or subjective evaluations or both. Guided by the Rowe and Kahn model, the current study expands prior work by examining the association of objective and subjective components of SA with individuals’ life satisfaction and level of optimism across adulthood. Data were f...

Unlabelled: Introduction: The Mindfulness-Based Stress Reduction program for breast cancer survivors (MBSR [BCs]) is a stress-reducing program designed to increase cognitive functioning through four meditational practices. This randomized clinical trial aimed to determine if improvements in cognitive functioning and perceived cognitive abilities a...

Background Genetics may influence symptoms experienced by breast cancer survivors (BCS) by moderating the effects of stress-reducing interventions, including the Mindfulness-Based Stress Reduction (MBSR(BC)) program, to reduce symptom severity. As part of a larger clinical trial, the aim of this study was to evaluate genetic variants as moderators...

Introduction: The Mindfulness-Based Stress Reduction (MBSR) Program for breast cancer survivors (BCS) is designed to enhance cognitive training through formal and informal meditational practices. This randomized clinical trial (RCT) aimed to evaluate if BCS assigned to either the MBSR(BC), Breast Cancer Education Support (BCES), or Usual Care (UC)...

Guided by the Rowe and Kahn model, the current study examined the longitudinal association of objective and subjective components of successful aging (SA) with individuals’ life satisfaction and level of optimism across adulthood aiming to validate the related scanty existing research. Data were from waves 2 and 3 (2004–14) of the Midlife in the Un...

Previous research showed the importance of control beliefs for many life outcomes. The present study examines associations between subjectively perceived work environment and objectively measured work activities at the beginning of midlife as a central developmental phase in the context of work, with control beliefs across the subsequent 20 years....

Objectives: This study examined the role of caregivers' perception of cognitive impairment in burden of family caregivers in Alzheimer's disease (AD). We hypothesized that the evaluation of cognitive impairment by family caregivers plays a pivotal role in burden. Methods: The study included 110 dyads (person with AD and their caregiver) recruite...

It is well-established that more frequent social interaction is associated with higher well-being across the lifespan. The present study examines the role of frequency of interactions via different modalities on older adults’ weekly well-being during the COVID-19 pandemic, where people had to adapt their communication behavior and reduce in-person...

Objectives Some research conceptualizes routineness of daily life as an indicator of cognitive vulnerability that would lead to lower well-being in older age, whereas other research expects routineness to give rise to more meaning and stability in life and thus to higher well-being. Further research is needed to understand routineness in older adul...

We investigated the effects of social connection and engagement on trajectories of function and depressive symptoms in stroke. Methods Participants were 898 individua...

Older adults increasingly use digital technologies to communicate with others. In the present study, we examine the role of interaction modality (face-to-face, telephone, digital) for perceived quality of social interactions. We use data from 118 participants (age: M = 72 years, SD = 5, range = 65 to 94; 40% women), who reported on their social int...

Background: Intimate partner relationships foster individuals’ well-being throughout the lifespan. However, dissatisfying or conflict-laden relationships can have a detrimental impact on well-being and relationship quality. The majority of older adults live together with a spouse/partner, and intimate relationships are one of the most important soc...

Objective Project VITAL At Home aimed to combat social isolation and loneliness in family caregivers of people with dementia through purposeful engagement and connection. This project examined the effects of technology on caregiver loneliness and well-being, as well as their technology experiences, during the COVID-19 pandemic. Methods Family care...

Objectives: Work is an important developmental context in adulthood, yet little is known about how it contributes to personality trajectories in midlife. The present study examines how subjectively perceived work environment (autonomy, innovation, social integration, stress) and objectively measured work activities (activities related to informati...

Biomarkers defining biological age are typically laborious or expensive to assess. Instead, in the current study, we identified parameters based on standard laboratory blood tests across metabolic, cardiovascular, inflammatory, and kidney functioning that had been assessed in the Berlin Aging Study (BASE) (n = 384) and Berlin Aging Study II (BASE-I...

Time spent on being with others (social interactions) and being alone (solitude) in day to day life might reflect older adults' agentic regulatory strategies to balance the needs to belong and to conserve energy. Motivated from a joint lifespan psychological and social relationship theoretical perspective, this study examined how time spent on soci...

Objectives Higher inflammation has been linked to poor physical and mental health outcomes, and mortality, but few studies have rigorously examined whether changes in perceived stress and depressive symptoms are associated with increased inflammation within family caregivers and non-caregivers in a longitudinal design. Design Longitudinal Study....

Working memory (WM) training has been proposed as a promising intervention to enhance cognitive abilities, but convincing evidence for transfer to untrained abilities is lacking. Prevalent limitations of WM training studies include the narrow assessment of both WM and cognitive abilities, the analysis of manifest variables subject to measurement er...

It is widely established that physical activity is associated with better cognitive outcomes, and accumulating evidence suggests that mind-body practice (MBP, e.g., movement therapies such as yoga) may yield similar benefits. Personality is related to both daily activities and cognition, but its role in the association between MBP and cognition is...

Objectives: While being socially active is beneficial for well-being in older age, it is unclear whether effects of social interactions on well-being indicate "the more the merrier" or they have limits as individuals socialize more or less across different days. This study addressed diminishing returns to social interaction frequency for well-bein...

Objectives The spousal relationship is one of the most important social contexts in old age and the loss of a spouse/partner is associated with stress and cognitive decline. In the present study, we examined whether social relationships can buffer potential negative effects of spousal loss on cognition. We examined the role of social network, socia...

Older adults increasingly use digital communication technologies to stay connected to others. In the present study, we examine the role of social interactions for older adults’ daily well-being focusing on three interaction modalities (face-to-face, telephone, and digital). We use data from 116 participants (age: M = 72 years, SD = 5, range = 65 to...

Recent research suggests that engagement with particular activities, such as music, can influence age-related changes in episodic memory. However, it is unclear whether, and to what, extent music engagement is associated with the trajectory of episodic memory. The objective of this study is to examine how passive (i.e., listening to music) and/or a...

Intimate relationship partners dynamically covary in their affective states. One mechanism through which intimate relationship partners experience and shape each other’s affective states is affect contagion, i.e., the spread of affective states from one person to another. The degree to which social-cognitive processes are involved in affect contagi...

It is widely established that physical activity is associated with better cognitive outcomes, and accumulating evidence suggests that mind-body practice (MBP) may yield similar benefits. Personality is related to both daily activities and cognition, but its role in the association between MBP and cognition is not well understood. The current study...

With the increasing prevalence of Alzheimer’s and related dementias, it is becoming a growing public health concern to identify modifiable risk factors to prevent cognitive decline. Previous research suggest that physical exercise may promote cognitive function in aging. However, most of this research is based on experimental or cross-sectional stu...

Lack of social engagement and the resulting social isolation can have negative impacts on health and well-being, especially in senior care communities and for those living with dementia. Project VITAL leverages technology and community resources to create a network for connection, engagement, education, and support of individuals with dementia and...

Intimate relationship partners dynamically covary in their affective states. One mechanism through which intimate relationship partners experience and shape each other's affective states is affect contagion, that is, the spread of affective states from one person to another. Most studies on affect contagion in daily life focused on younger couples....

Associations between social relationships and well-being are widely documented across the lifespan, including in older age. Older adults increasingly use digital communication technologies. In the present study, we examine the role of social interactions for older adults’ daily well-being with a focus on three interaction modalities (face-to-face,...

Background and objectives: Positive associations between social connection/engagement and cognitive function are well documented. However, little is known about whether social connection/engagement can buffer the impact of serious brain injury such as stroke on cognitive functioning. Research design and methods: Participants were 898 individuals...

Objectives Cognitive function is a key component of healthy aging. While conventional physical activities (walking, jogging, etc.) have been shown to support health in late-life, including cognitive health, it remains unclear whether traditional Eastern mind-body practices (MBP) have long-term cognitive benefits above and beyond conventional leisur...

Objectives: A growing body of research has documented associations between social relationships and cognitive function, while findings are less clear regarding specific aspects of social relationships that are relevant to change in cognitive function. Furthermore, it is unclear whether associations differ at the between-person and within-person le...

Introduction: The loss of a spouse is among the most stressful life events. Whilst grief and mourning vary across cultures, most longitudinal studies have been conducted in Western societies. Adding to prior research, this study examines the role of resources available prior to spousal bereavement and changes therein for trajectories of well-being...

Working memory (WM) training has been proposed as a promising intervention to enhance cognitive abilities, but convincing evidence for transfer to untrained abilities is lacking. Prevalent limitations of WM training studies include the narrow assessment of both WM and cognitive abilities, the analysis of manifest variables subject to measurement er...

Objectives: To determine whether music engagement influences middle-aged and older adults' performance on episodic memory tasks. Methods: Secondary data analysis of a sample (N = 4,592) of cognitively healthy adults from the 2016 Health and Retirement Study were used for this study. Multivariable regression models were used to analyze the cross-...

Cognitively enriching environments are usually related to higher levels of cognitive performance, while associations with longitudinal change are less clear. In the present study, we used 20-year longitudinal data from the German Interdisciplinary Longitudinal Study of Adult Development and Aging (ILSE) to examine the role of occupational factors f...

Cognitive function is an important component of healthy aging and physical activities have been shown to support late life cognitive function. However, it is unclear whether non-traditional physical activities provide additional benefits for cognitive function above and beyond traditional leisure physical activities. This study examines the associa...

Background and Objectives The current COVID-19 pandemic and social distancing measures are an extreme stressor that might result in negative emotional experiences and feelings of loneliness. However, it is possible that social relationships might have a protective effect. In the present study, we examine how the COVID-19 pandemic affected older adu...

Being able to use the Internet is becoming increasingly important in today's digitized society. Evidence suggests that older adults are at risk of being left behind by technological developments. We examined Internet adoption in older adults in relation to sociodemographic, health, cognitive, social, and personality factors. We used data from the H...

Previous research documented positive associations between cognitively stimulating work and levels of cognitive performance, while longitudinal associations are less clear. We used 20-year longitudinal data from the Interdisciplinary Longitudinal Study of Adult Development and Aging (ILSE) to examine the role of perceived work environment (autonomy...

Background: Digital technologies are increasingly pervading our daily lives. Although older adults started using digital technologies later than other age groups, they are increasingly adopting these technologies, especially with the goal of communicating with others. However, less is known about how online social activities are embedded in older a...

Objectives Mind-body practices (MBP), such as Yoga or Tai-Chi, have increased in popularity in the past 25 years in the US. These activities may help promote a less sedentary lifestyle and may have positive effects on health. The objective of the present study is to understand the prevalence and trends of MBP in US adults and the factors associated...

We investigated whether similarity between partners in positive and negative affect is associated with the perception that one manages everyday life well together as a couple (dyadic mastery). To this end, we used data from 99 older couples (mean age = 75 years; mean length of relationship = 45 years) obtained 5 times a day over 7 consecutive days...

Empathic accuracy involves identifying the emotions of others. Most evidence is based on younger samples, which is limiting because of well-established motivational shifts that occur in older adulthood. Here, we examine associations between fluctuations in happiness and empathic accuracy, using momentary assessments of happiness from 107 couples (...

Neuroticism is associated with heightened reactivity to social stressors. However, little is known about the micro-processes through which neuroticism shapes – and is shaped by – affective experiences in close relationships. We examine the extent to which momentary affect is coupled with one’s relationship partner, whether the strength of this coup...

Objectives: Retirement is one of the major life course transitions in old age. Evidence suggests that exiting work life is associated with notable changes in life satisfaction, which are heterogeneous across individuals. Effects of retirement transitions on life satisfaction have been understudied in couples. We examined change in life satisfactio...

UNSTRUCTURED Digital technologies are increasingly pervading our daily lives. Although older adults started using digital technologies later than other age groups, they are increasingly adopting these technologies, especially with the goal of communicating with others.

Although older adults started using digital technologies later than other age groups, they are increasingly adopting these technologies, especially with the goal of communicating with others. However, less is known about how online social activities are embedded in older ad...

Human functioning and development are shaped by sociocultural contexts and by the historical changes that occur in these contexts. Over the last century, sociocultural changes such as increases in early life education have profoundly reshaped normative developmental sequences. In this article, we first briefly review how history-graded changes have...

Interactions with technology have been shaping human society since its beginning. Recently, digitalization has pervaded all aspects of our lives and provided us with new ways to communicate with our social contacts and develop new social ties. We address how these changes shape the social lives of older adults today. Several factors may give rise t...

Studies of historical and societal influences on cognitive aging generally document that later-born cohorts outperform earlier-born cohorts on tests of fluid cognitive performance. It is often noted how advances in educational attainment in childhood and adolescence may contribute to these historical improvements in cognitive aging. Less is known a...

Individual development and relationships are embedded in a sociohistorical context. In the present study, we examined how relationship functioning of heterosexual couples differs across historical time in 3 population-based samples. We used data from the Swiss Social Stratification, Cohesion and Conflict in Contemporary Families Study (COUPLES: wav...

It is a well-replicated finding that reaction time is correlated with performance in intelligence tests. According to the binding hypothesis of working memory capacity, the ability to establish bindings between elements and to integrate them into new structural representations is the source of the common variance between different cognitive tasks,...

Objectives: Well-being typically exhibits pronounced deteriorations with approaching death, with sizeable interindividual variations in levels and changes. It is less well understood how psychosocial factors contribute to these individual differences. We examined whether and how social integration is associated with terminal trajectories of well-b...

Lifespan development is embedded in multiple social systems and social relationships. Lifespan developmental and relationship researchers study individual codevelopment in various dyadic social relationships, such as dyads of parents and children or romantic partners. Dyadic data refers to types of data for which observations from both members of a...

General well-being is known to deteriorate sharply at the end of life. However, it is an open question how rates of terminal change differ across affective and evaluative facets of well-being and if individual difference correlates operate in facet-specific ways. We examined how discrete affective states (happy, angry, fearful, sad) and satisfactio...

Background: Research on terminal decline has widely documented that cognitive performance steeply declines with nearing death. To date, it is unclear whether these changes are normative, based on pathologies associated with (preclinical) dementia, or both. Objectives: We analyzed heterogeneity in trajectories of terminal cognitive change in Swis...

A growing body of research has examined whether people’s judgments of their own memory functioning accurately reflect their memory performance at cross-section and over time. Relatively less is known about whether these judgments are specifically based on memory performance, or reflect general cognitive change. The aim of the present study was to e...

Subjective memory change (SMC) in adulthood involves the perception that one’s memory has declined from earlier levels of function. SMC has been conjectured to be more accurate than concurrent subjective memory because people use themselves as a standard of comparison. We used data from two longitudinal studies to contrast the accurate-monitoring-o...

Objectives: It is well established that daily perceived control is closely associated with lower negative affect among older adults. However, it is an open question whether control perceptions of one's partner are also uniquely associated with one's own negative affect. Method: To examine such associations in dyads of older long-term partners, w...

Background The last decades have seen great advances in the understanding, treatment, and prevention of cardiovascular disease (CVD). Although mortality rates due to CVD have declined significantly in the last decades, the burden of CVD is still high, particularly in older adults. This raises the question whether contemporary populations of older a...

The sociocultural context surrounding individuals has undergone many important changes over the recent decades and centuries. Lifespan psychological and life course sociological perspectives postulate that individual development is shaped by both ontogenetic and historical processes. Although cohort differences in cognitive performance are well doc...

It is well documented that well-being typically evinces precipitous decrements at the end of life. However, research has primarily taken a postdictive approach by knowing the outcome (date of death) and aligning, in retrospect, how well-being has changed for people with documented death events. In the present study, we made use of a predictive appr...

Intellectual engagement (IE) refers to enjoyment of intellectual activities and is proposed as causal for knowledge acquisition. The role of IE for cognitive development was examined utilizing 2-year longitudinal data from 112 ninth graders (average baseline age: 14.7?years). Higher baseline IE predicted higher baseline crystallized ability but not...

Educational researchers have long been interested in quantifying the amount of change in student achievement as a result of schooling. In this paper, we present an intensive longitudinal study of student achievement and cognitive ability over a time span of two academic years, from the beginning of ninth grade until the end of tenth. One hundred an...

Objectives: Spouses are proximal contexts for and influence each other's behaviors, particularly in old age. In this article, we forward an integrated approach that merges state space grid methods adapted from the dynamic systems literature with sequence analysis methods adapted from molecular biology into a "grid-sequence" method for studying int...

It has long been proposed that cognitive aging in fluid abilities is driven by age-related declines of processing speed. Although study of between-person associations generally supports this view, accumulating longitudinal between-person and within-person evidence indicates less strong associations between speed and fluid cognitive performance. Ini...

Correctly identifying other's emotional states is a central cognitive component of empathy. We examined the role of fluid cognitive performance for empathic accuracy for happiness in the daily lives of 86 older couples (mean relationship length = 45 years; mean age = 75 years) on up to 42 occasions over 7 consecutive days. Men performing better on...

Dissimilarities between partners in prominent domains of functioning are often thought to be a risk factor for compromised relationship quality and relationship dissolution. However, the nature, correlates, and consequences of developmental trajectories of within-couple dissimilarities in key quality-of-life indicators such as life satisfaction are...

Background: Lifespan psychological and life course sociological perspectives indicate that individual development is shaped by social and historical circumstances. Increases in fluid cognitive performance over the last century are well documented and researchers have begun examining historical trends in personality and subjective well-being in old...

One key objective of life span research is to examine how individual development is shaped by the historical time people live in. Secular trends favoring later-born cohorts on fluid cognitive abilities have been widely documented, but findings are mixed for well-being. It remains an open question whether secular increases in well-being seen in earl...

Conceptual notions and empirical evidence suggest that the intraindividual correlation (iCorr) of positive affect (PA) and negative affect (NA) is a meaningful characteristic of affective functioning. PA and NA are typically negatively correlated within-person. Previous research has found that the iCorr of PA and NA is relatively stable over time w...
