The aim of this study is to: (1) compare the association between various levels of physical activity (PA) and mortality; and (2) examine the potential modifying effect of depressive symptoms on the PA-mortality associations. Previous large scale randomized studies rarely assess the association in conjunction with modifying effects of depressive…

The purpose of this study was to examine cohort comparisons in levels of resources (e.g., mental health, physical functioning, economic and social resources, and cognitive functioning) for 211 community-dwelling centenarians (whose Mini-Mental Status Examination score was 23 or higher) of phases I and III of the Georgia Centenarian Study. The…

Objective: Marital difficulties can confer risk of coronary heart disease, as in a study of outwardly healthy couples (T. W. Smith et al., 2011) where behavioral ratings of low affiliation and high control during marital disagreements were associated with asymptomatic coronary artery disease (CAD). However, taxometric studies suggest that marital…

Purpose: In this study, the authors investigated how acoustic distortion affected younger and older adults' use of context in a lexical decision task. Method: The authors measured lexical decision reaction times (RTs) when intact target words followed acoustically distorted sentence contexts. Contexts were semantically congruent, neutral, or…

Older people with an intellectual disability (ID) have been shown to have similar to increased cardiovascular risks as compared to the general population. Peripheral arterial disease (PAD), atherosclerosis distal from the aortic bifurcation, is associated with increased cardiovascular morbidity and mortality. The prevalence of PAD has not been…

It is widely recognized that experience with cognitive tests can influence estimates of cognitive change. Prior research has estimated experience effects at the level of groups by comparing the performance of a group of participants tested for the second time with the performance of a different group of participants at the same age tested for the…

Background: A growing literature indicates that the Child Behavior Checklist-Dysregulation Profile (CBCL-DP) identifies youths with heightened risk for severe psychopathology, comorbidity, and impairment. However, this work has focused on school-age children and adolescents; no studies have examined whether preschool-aged children with the CBCL-DP…

Two experiments tested the effect of temporal interference on order memory for fixed and random sequences in young adults and nondemented older adults. The results demonstrate that temporal order memory for fixed and random sequences is impaired in nondemented older adults, particularly when temporal interference is high. However, temporal order…

Purpose: Older adults exhibit difficulty understanding speech that has been experimentally degraded. Age-related changes to the speech mechanism lead to natural degradations in signal quality. We tested the hypothesis that older adults with hearing loss would exhibit declines in speech recognition when listening to the speech of older adults,…

The present study has two main interests. First, some pending issues about the psychometric properties of the CTAC (an anxiety questionnaire for blind and visually-impaired people) are assessed using item response theory (IRT). Second, the linear model is compared to the graded response model (GRM) in terms of measurement precision, sensitivity…

During a number of years Swedish municipalities have work with improvement of competence and long-term quality in elderly care. The overall aim of the present study was to compare different learning activities (workplace improvement and/or courses), and to relate these activities to learning climate, learning strategies, and perception of care…

Autism is a lifelong neurodevelopmental disorder, with a known impact on quality of life. Yet the developmental trajectory of quality of life is not well understood. First, the effect of age on quality of life was studied with a meta-analysis. Our meta-analysis included 10 studies (published between 2004 and 2012) with a combined sample size of…

The primary purpose of the present study was to examine age differences in choice deferral when young and older adults make high vs. low conflict decisions in two domains (i.e., health and commodity). Sixty young and 60 older adults were presented with four different decision scenarios in which they could either choose an option or use choice…

This study investigated perceptions of love across the lifespan using Sternberg's triangular theory of love, which distinguishes between passion, intimacy, and commitment. The study aimed to (a) investigate the psychometric properties of the short Triangular Love Scale (TLS-short) in adolescents and adults (see Appendix), and (b) track age and…

Studies on intra-household allocation of resources show that exogenous increase in mothers' income has larger effect on children's outcomes than the same increase in fathers' income, suggesting gender differences may exist in parents' altruism towards their children. Using self-reported life happiness and life satisfaction, we investigate the…
