Loneliness—the subjective experience of social isolation—is a common that can become an enduring feature everyday life. How does feeling lonely relate to spending time alone? In this descriptive-exploratory study, we used the Electronically Activated Recorder (EAR), naturalistic observation tool samples sounds from participants' daily lives, assess spent alone as index isolation. We combined data three (N = 426) examine association between and objectively-assessed isolation, whether varies...
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...
Past research using the Electronically Activated Recorder (EAR), an observational ambulatory assessment method for real–world measurement of daily behaviour, has identified several behavioural manifestations Big Five domains in a small college sample ( N = 96). With use larger and more diverse pooled data from 462 participants total four community samples who wore EAR 2 to 6 days, primary purpose present study was obtain precise generalizable effect estimates Five–behaviour relationships...
Given its centrality in scholarly and popular discourse, morality should be expected to figure prominently everyday talk. We test this expectation by examining the frequency of moral content three contexts, using methods: (a) Participants' subjective estimates (N = 581); (b) Human analysis unobtrusively recorded in-person interactions 542 participants; n 50,961 observations); (c) Computational Facebook posts 3822 111,886 observations). In their self-reports, participants estimated that 21.5%...
Language markers derived from structured clinical interviews and assessments have been found to predict age-related normal pathological cognitive functioning. An important question, then, is the degree which language that people use in their natural daily interactions, rather than elicited within specifically for assessment, carries information about key functions associated with decline. In an observational study, we investigated how variability executive functioning (EF) manifests patterns...
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...
The retrieval of autobiographical memories is an integral part everyday social interactions. Prior laboratory research has revealed that older age associated with a reduction in the episodic memories, and ability to elaborate these details. However, how age-related reductions specificity unfold contexts remains largely unknown. Also, constraints laboratory-based approach have limited our understanding semantic memory linked age. To address gaps knowledge, we used smartphone application known...
Abstract Over the recent years, machine learning techniques have been employed to produce state-of-the-art results in several audio related tasks. The success of these approaches has largely due access large amounts open-source datasets and enhancement computational resources. However, a shortcoming methods is that they often fail generalize well tasks from real life scenarios, domain mismatch. One such task foreground speech detection wearable devices. Several interfering factors as...
HIV-negative individuals with a family history of dementia (FHD) are more likely to develop than those without FHD. Whether FHD increases risk for neuropsychological (NP) impairment in HIV+ persons is unknown. As part multisite study into HIV-associated neurocognitive disorders (HAND), the authors captured free-response, self-report question, and assessed NP performance comprehensive battery tests. The examined (N=190) (N=916) self-reported Despite fact that group had factors typically...
Abstract. The present study examined the interpersonal focus within autobiographical memories (AMs) of older and younger adults from perspective socioemotional selectivity theory (SST). Specifically, we measured directly through rater codings (relational vs. individual focus) social word use, indirectly personal pronoun use. Forty-five ( M age = 76.76) 25 18.64) recalled positive negative AMs, which were then coded processed computerized text analysis software to obtain word-use counts....
The literature on the relationship between social interaction and executive functions (EF) in older age is mixed, perhaps stemming from differences EF measures conceptualization/measurement of interaction. We investigated 102 cognitively unimpaired adults (ages 65-90). Participants received an battery to measure working memory, inhibition, shifting, global EF. measured loneliness subjectively through survey isolation objectively naturalistic observation. Loneliness was not significantly related any (

Abstract Language use during structured clinical tasks predicts pathological cognitive aging. However, reflect only a narrow band of potential communication contexts, which limits the ability to capture processes manifested in language under more natural conditions (i.e., minimal constraints). The Electronically Activated Recorder (EAR) makes it possible sample from full ecology individuals’ interactions. As interactions are cognitively complex, everyday life might be especially sensitive...
The empirical literature on the relationship between social interaction and executive functions in older age is mixed, perhaps stemming part from differences functioning measures (e.g., a single test or battery) conceptualization measurement of loneliness and/or isolation). Our study investigated sample (N = 102) cognitively unimpaired, functionally independent adults (ages 65 - 90). Participants received comprehensive battery with working memory, inhibition, shifting, global functioning. We...
Sighing is a common nonverbal everyday behavior thought to signal the experiencing of negative emotions. Prior research from small-scale study suggests that observed daily expressions sighing associated with subclinical depression (Robbins et al., 2011). This paper replicates and extends these findings, hypothesizing individual differences in emotionality are frequency spontaneous sighing. Study 1 (N = 320) documents strong lay assumption frequent signals dispositional emotionality. 2...
