Two studies were conducted to investigate age-related differences between young and older adults in the impact of a map being available or not while performing aligned and counter-aligned pointing tasks. In the first study, 19 young adults (aged 20-30) and 19 young-old adults (aged 65-74) studied a map and performed a pointing task. In the second, three groups of adults, 19 of them young (aged ...

In this paper, we model the associations of childhood health on adult health and socio-economic status outcomes in China using a new sample of middle aged and older Chinese respondents. Modeled after the American Health and Retirement Survey (HRS), the CHARLS Pilot survey respondents are 45 years and older in two quite distinct provinces-Zhejiang, a high growth industrialized province on the Ea...

Vascular remodeling and changes in vascular responsiveness occur in the rat cerebrum with old age. This includes reductions in cerebral arteriolar numerical density, cross-sectional area, distensibility, the relative proportion of distensible elements in the cerebral arteriolar wall, and reduced endothelium-dependent relaxation. The purpose of this study was to test the hypothesis that old age ...

This article provides evidence about the quality of retrospective childhood health histories given to respondents in the Health and Retirement Survey (HRS) and the Panel Study of Income Dynamics (PSID). Even though information on early life health events is critical, there is legitimate skepticism about the ability of older respondents to remember specific health problems that they had during c...

We studied the association between height and IQ in 209 Dutch twin pairs at the ages of 5, 7, 10 and 12 years, 208 twin pairs at 16 and 1...
