This article discusses what is known about the economic status of the aged. Numerous complexities involved in the assessment of their status are discussed. Compared with most other recent assessments, this study finds a less favorable status for the aged relative to other age groups. The focus is on an examination of detailed age groups, rather than summary aged and nonaged groups-thus providin...

Two studies, involving a total of 460 adults between 18 and 87 years of age, were conducted to determine which of several hypothesized processing components was most responsible for age-related declines in working memory functioning. Significant negative correlations between age and measures of working memory (i.e., from -.39 to -.52) were found in both studies, and these relations were substan...

Previous studies have shown that deficiencies in visuospatial perception and semantic processing in people with Williams syndrome (WS) are due to deficient central cohesiveness. Unlike previous studies that used abstract stimuli, this study used pictures to determine the relative ability of people with WS to integrate contextual information with the aim of exploring the nature of central cohere...

Two studies were conducted with adults from a wide range of ages to investigate the mechanisms by which a slower processing speed contributes to adult age differences in short-term learning. Although statistical control of measures of perceptual speed substantially reduced the agerelated variance in measures of associative leaming and of maze leaming, there was little evidence that speed exerte...

This paper considers a marriage market with two-sided search and transferable utility in which the match payoff depends on age. It characterizes a set of payoff functions consistent with two salient marriage age patterns, (1) assortative matching by age, and (2) “differential age matching”, a formalization of the age difference at marriage between men and women. Some simple conditions on slope ...

Age differences in affective/experiential and deliberative processes have important theoretical implications for judgment and decision theory and important pragmatic implications for older-adult decision making. Age-related declines in the efficiency of deliberative processes predict poorer-quality decisions as we age. However, age-related adaptive processes, including motivated selectivity in ...

— I study the effect of a recent expansion in India’s National Old Age Pension Scheme on elderly well-being. Estimates suggest that public pension has a modestly negative effect on the employment of elderly/near elderly men with a primary or lower education but no effect on the employment of similar women. Pension raised family expenditures, lowering poverty, and the effect was smaller on famil...

The disease- and mortality-related difference between biological age based on DNA methylation and chronological age (Δage) has been found to have approximately 40% heritability by assuming that the familial correlation is only explained by additive genetic factors. We calculated two different Δage measures for 132 middle-aged female twin pairs (66 monozygotic and 66 dizygotic twin pairs) and th...

Age differences in frontal and hippocampal activations in working memory were investigated during a maintenance and subsequent probe interval in an event-related fMRI design. Younger and older adults either viewed or maintained photographs of real-world scenes (extended visual or maintenance conditions) over a 4-sec interval before responding to a probe fragment from the studied picture. Behavi...

Methods: Sixty patients undergoing various aging face surgical procedures were randomly chosen for analysis. Preoperative and postoperative photographs were evaluated. Raters were presented with photographs in a random assortment and were asked to estimate the age of the patient. Perceived age difference was defined as the difference between the chronological age and the estimated age, and the ...
