The referential communication task was used to see if high off-target verbosity (OTV), defined as excessive speech that is lacking in focus, negatively affects communication of nonautobiographical information. The task required 1 individual (the director) to communicate descriptions of abstract figures to another (the matcher). Out of 455 adults aged 63 to(More)
In order to understand how the brain prepares for and executes a switch in task demand, we measured reaction time (RT), accuracy, and event-related brain potentials associated with performance in single and mixed-task blocks using a cued design. Our results show that trials which repeat in a mixed-task block (repeat trials) were more demanding than trials(More)
We investigated age-related differences in task-switching performance by using behavioral measures and event-related brain potentials. We tested younger and older adults, and we separated older adults into groups with high and low working memory (WM); that is, we separated them into old-high-WM and old-low-WM groups. On average, all participants responded(More)
The authors comment on D. F. Hultsch, C. Hertzog, B. J. Small, and R. A. Dixon's (1999) report of the latest results of the Victoria Longitudinal Study, which are presented as a test of the engagement hypothesis, and on their reanalysis of the data from the Veterans Study (Pushkar Gold et al., 1995), which proposes an alternative model of intellectual(More)
This study investigated social behavior in older adults with varying levels of off-target verbosity (OTV). After screening 455 adults in Phase 1, 198 individuals were selected to participate in both a get-acquainted conversation and an experimental cues situation and to complete social and cognitive measures. Higher OTV participants had lower cognitive(More)
The hypothesis that individual differences in adult intellectual development reflect variation in life context and personality was examined in 132 World War II (WWII) veterans. Intelligence data from the Canadian Army M Test were available for 3 occasions, WWII, 1984-1986 (Int85), and 1989-1991 (Int90). Performance declined over the 45 years on 5 subtests(More)
Parameters of everyday activities in relation to cognitive, social, and emotional competence were examined in 2 studies. The parameters included frequency, difficulty, importance, intentions for future activities, changes in past activities, and ability of performance. The challenge hypothesis, in which performance of optional activities experienced as(More)
Based on recent research with young, depressed adults, age-related cognitive declines and decreased autobiographical specificity were hypothesized to predict poorer social problem-solving ability in older than in younger healthy adults. Priming autobiographical memory (ABM) was hypothesized to improve social problem-solving performance for older adults.(More)
This study tested predictions based on continuity and activity theories, examining effects of continuity and change in activity parameters on positive affect (PA) and negative affect (NA). Retired men and women (N = 368) completed measures of everyday activities and affect, repeating the measures after 2 years. Continuity of activity parameters and affect(More)
Differences occur in the demographic, health, and social network contexts of men and women, all of which are associated with successful aging. The objectives of this study were to determine whether differences exist in satisfaction in specific domains, in general life satisfaction and in the paths for life satisfaction for men and women.
