    Subjective Memory and Objective Cognition in Older Adults with CIND There are a number of different terms used in both research and practice to define mild memory or cognitive problems in older adults who do not have dementia. Older adults care less about what other people think of them (Elder Options, ). Older Americans have more voting power because they’re the fastest growing demographic (Elder Options, ). Older adults who stay connected to others have better health and life satisfaction (Elder Options, ).

      Growing Old in America: Expectations vs. Reality ages 85 and older say they are experiencing some memory loss, compared with 27% of those ages and 20% of those ages Similarly, 30% of those ages 85 and older say they often feel sad or depressed, compared with less than 20% of those who are The regression analysis we. Older adults showed better implicit than explicit memory and better implicit memory than the younger, while the reverse was true for the younger adults. However, on a further test which required younger participants to engage in a number task simultaneously with the color task, younger adults behaved like older ones.

Participants (N = 40) performed visual motor tasks while reaction times (RTs) and event-related potentials were recorded. Results RTs were slower for the older subjects, but accuracy was not impaired. At event-related potential level, the late P3 component was delayed in older subjects, but those who participated in sports showed less delay. The RTs of middle-age .

The current study was carried out to determine the electrophysiological correlates of source memory discrimination in younger and older adults.

Event-related potentials (ERPs) and continuous electrocardiographic (ECG) data were collected from younger (M= 21 years) and older (M= 71 years) adults during a source memory : Wilma. Veenhof. The current study was carried out to determine the electrophysiological correlates of source memory discrimination in younger and older adults.

Event-related potentials (ERPs) and continuous electrocardiographic (ECG) data were collected from younger {M-2 \ years) and older (A/ = 71 years) adults during a source memory : Wilma Veenhof. The older adults only demonstrated neural correlates of familiarity-based source recognition in the unitized condition.

These findings suggest that a unitized encoding strategy could improve source memory performance in older adults by enhancing the involvement of familiarity in source by: 8. This study examined the effects of physical activity on working memory in older adults using both behavioral and neuroelectric measures.

Participants included 22 younger adults (M age =SD = ; age range = 18–24; 7 male) and 20 older adults (M age =SD = ; age range = 60–92; 8 male), recruited from Brandeis University and the greater Boston area (for a summary of demographics, see Table 1).Author: Laura E.

Paige, Eric C. Fields, Eric C. Fields, Angela Gutchess. Results indicated that the frontal composite, which has consistently been associated with source memory performance in older adults, was unrelated to source memory in young adults, although it was sensitive to a demanding working memory task.

The memory composite, however, predicted performance in the young by:   Working memory (WM) declines with ageing, and this may cause problems in older workers who have to do complex work requiring WM.

We tested the assumption that an increase in WM load negatively affects performance and results in impaired cardiovascular adaptation to changing task demands in older workers relative to younger ones.

In the present study, older adults may experience a larger difference in retrieval difficulty between lag conditions than do young adults, given age-related changes in episodic memory (see Balota et al., ).

Hence, one might expect larger benefits of spacing in older than in younger by: Thus, older adults may be at least as capable as younger adults to make proper decisions. Indeed, general semantic knowledge (e.g., Verhaeghen, ) and implicit memory (H ealey, Campbell, & Hasher,for a review), both generally preserved with healthy aging, could support older adults’ decision making in some contexts.

Older adults. Most middle adults characterize the relationship with their parents as affectionate. Indeed a strong bond often exists between related middle and older adults. Although the majority of middle adults do not live with their parents, they usually maintain frequent and positive contact.

Because research in older adults has served as a model for understanding the effects of physical activity and fitness on the developing brain during childhood, the adult research is briefly discussed.
