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 present study, we examine role of interactions for adults’ daily with a focus on three interaction modalities (face-to-face, telephone, digital). Specifically, (a) whether people who more socially active than others report higher levels (b) how day-to-day fluctuations number associated well-being,...
While being socially active is beneficial for well-being in older age, it unclear whether effects of social interactions on indicate "the more the merrier" or if they have limits as individuals socialize less across different days. This study addressed diminishing returns to interaction frequency well-being.We examined data from an event-contingent experience sampling 116 Swiss adults (65 94 years old) over 21 Participants reported face-to-face once occurred and daily (i.e., positive...
Women are widely assumed to be more talkative than men. Challenging this assumption, Mehl et al. (2007) provided empirical evidence that men and women do not differ significantly in their daily word use, speaking about 16,000 words per day (WPD) each. However, concerns were raised sample was too small yield generalizable estimates age context homogeneous permit inferences beyond college students. This registered report replicated extended the previous study of binary gender differences use...
Abstract Out-of-home mobility and neighborhood environment have been, respectively, shown to be associated with older adults’ cognitive abilities they may combined effects. Adopting an ecological perspective mobility–cognition associations, this study examined daily maximum distance from home in relation working memory performance community-dwelling adults the moderation effect of environments. Analyses included data over 947 days 109 Swiss aged 65 89 years. Over two weeks, participants wore...
Abstract Time spent on being with others (social interactions) and alone (solitude) in day to life might reflect older adults' agentic regulatory strategies balance the needs belong conserve energy. Motivated from a joint lifespan psychological social relationship theoretical perspective, this study examined how time interactions solitude alternatively unfolds within individuals daily life, relating individual differences trait‐level well‐being fatigue. Over 21 days, total of 11,172 valid...
Prominent theories of aging emphasize the importance resource allocation processes as a means to maintain functional ability, well-being and quality life. Little is known about which activities what activity patterns actually characterize daily lives healthy older adults in key domains functioning, including spatial, physical, social, cognitive domains. This study aims gain comprehensive understanding community-dwelling over an extended period time across diverse range domains, examine...
Older adults increasingly use digital technologies to communicate with others. The goal of the present study is understand role interaction modality for perceived quality social interactions. We data from 118 participants (age: M = 72 years, SD 5, range 65 94; 40% women), who reported on their interactions (quality [valence, relatedness, calmness, meaningfulness], [face-to-face in-person, telephone, text-based digital], and purposes [e.g., small talk, conflict]) over 21 days in an...
Reminiscence is the act of thinking or talking about personal experiences that occurred in past. It a central task old age essential for healthy aging, and it serves multiple functions, such as decision-making introspection, transmitting life lessons, bonding with others. The study social reminiscence behavior everyday can be used to generate data detect from general conversations.The aims this original paper are (1) preprocess coded transcripts conversations German older adults natural...
Individuals' social connections and interpersonal experiences can both shape be shaped by cognitive functioning. This study examines longitudinal within-person associations between quality of relations, structure functioning in older age.
Language use and social interactions have demonstrated a close relationship with cognitive measures. It is important to improve the understanding of language behavioral indicators from context study early prediction decline among healthy populations older adults.This aimed at predicting an ability, working memory, 98 adults participating in 4-day-long naturalistic observation study. We used linguistic measures, part-of-speech (POS) tags, information extracted 7450 real-life audio recordings...
Introduction: Mobility as a multidimensional concept has rarely been examined day-to-day varying phenomenon in its within-person association with older adults’ daily well-being. This study associations between mobility and well-being community-dwelling adults set of GPS-derived indicators that were representative mobility. Methods: Participants wore custom-built mobile GPS sensor (“uTrail”) completed smartphone-based experience sampling questionnaires on momentary affective states (7 times...
Cross-sectional and long-term longitudinal studies have shown that engagement in diverse activities benefits cognitive performance older age, but it is unknown whether the beneficial effect holds within persons on a daily basis. This study examines within-person association between activity diversity working memory same day its time-lagged directionality days. It also effects of potential moderators association, including education, processing speed, crystallized intelligence, to understand...
The purpose of this study is to understand the functional health older adults in China and assess potential for advancing healthy active aging.Data 13,739 aged 50 years from Health Retirement Longitudinal Study 2011 were analyzed. Life expectancy good perceived health, chronic-disease-free life expectancy, severe impairment-free calculated using Sullivan's method.At age years, had a 7.0 6.7 men women, respectively. They would remain 8.4 8.6 without activity limitation 23.6 26.0 21.4 24.2...
Amid the growing interest in studying language use real life, this study, for first time, examined age effects on real-life use, as well within-person variations across different interlocutors. We speech samples collected via Electronically Activated Recorder (i.e., portable audio recorder that periodically records ambient sounds) a larger project. This existing dataset included more than 18,000 sound snippets (50-seconds long) from 53 American couples (breast cancer patients and their...
Functional psychologists are concerned with the performance of cognitive activities in real world relation to changes older age. Conversational contexts may mitigate influence aging on activity language production. This study examined effects familiarity interlocutors, as a context, production world.We collected speech samples using iPhones, where an audio recording app (i.e. Electronically Activated Recorder [EAR]) was installed. Over 31,300 brief files (30-second long) were randomly across...
Experimental research suggests that affect may influence prospective memory performance, but real-life evidence on affect-prospective associations is limited. Moreover, most studies have examined the valence dimension of in understanding cognitive performance daily life, with insufficient consideration arousal dimension. To maximize ecological validity, current study relationships between and using repeated assessments role resting heart rate these relationships. We both by categorizing into...
Does a single bout of activity engagement have short-term effects on cognition in daily life? Using smartphone-based ambulatory assessment design, this study examined the duration three types activities (i.e., sociocognitive, passive leisure, and physical activities) working memory performance. For seven times per day approximately every 2 hr) over 15 days, 150 healthy older adults (aged 65-91 years) Switzerland reported their present completed assessments. In an examination within-person...
This study investigated linear and nonlinear age effects on language use with speech samples that were representative of naturally occurring conversations.Using a corpus-based approach, we examined couples' conflict conversations in the laboratory. The conversations, from total 364 community-dwelling German-speaking heterosexual couples (aged 19-82), videotaped transcribed. We usage lower-frequency words, grammatical complexity, utterance filled pauses (e.g., äh ["um"]).Multilevel models...
Reminiscence—the act of recalling or telling others about relevant personal past experiences—plays an important role in the well-being older adults. Therefore, it is to develop intelligent systems aiming at improving elderly by reliably detecting reminiscence their everyday life conversations. Data imbalance one main challenges automatic detection from conversations, as reminiscing a rare event. In this paper, we address problem proposing methodology for coping with imbalanced data...
Although higher activity diversity is associated with well-being at the between-person level, it unknown whether a day related to within persons. Within 24 hr per day, there are limited number of activities on which individuals could spend their time and energy. Personal resources influence expenditure energy thus experience daily activities. This study examined associations between age self-related health moderated associations. For seven times over 2 weeks, 129 retired older adults (Mage =...
Abstract Objectives Some research conceptualizes routineness of daily life as an indicator cognitive vulnerability that would lead to lower well-being in older age, whereas other expects give rise more meaning and stability thus higher well-being. Further is needed understand adults relation abilities This study examined social interactions. Methods We data from event-contingent experience sampling with 103 Swiss community-dwelling (aged 65 84 years). Participants completed in-lab...
Abstract Prior research showed that activity engagement had short-term effects on numerical working memory over hours in German-speaking older adults. However, it is unclear whether these could be generalized to other cognitive outcomes and populations. This study examined associations of with performance using data from two studies included adults different demographic backgrounds the US. That is, 16 days’ 282 aged 70 90 years (M = 76.62, SD 4.68; 66% women; 44% White, 40% Black, 11%...
Abstract Health processes are studied increasingly commonly in older adults’ daily life. This symposium includes four studies that investigated health populations of diverse demographic backgrounds and explored differences the between individuals. First, with seven-day data from 207 adults aged 18-82 years, Ferguson, Corley, Scott found negative affect was associated occurrence stressors at both within-person momentary between-person levels, but age or neuroticism did not moderate...
