Three experiments investigated the aging of implicit spatial and spatiotemporal context learning in 2 tasks. In contextual cuing, people learn to use repeated spatial configurations to facilitate search for a target, whereas in higher order serial learning, they learn to use subtle sequence regularities to respond more quickly and accurately to a series of events. Results reveal a dissociation;...

Neuroimaging studies of cognitive and brain aging often yield massive datasets that create many analytic and statistical challenges. In this paper, we discuss and address several limitations in the existing work. (1) Linear models are often used to model the age effects on neuroimaging markers, which may be inadequate in capturing the potential nonlinear age effects. (2) Marginal correlations a...

The current study examined the role of temporal resolution of attention in the decline in multiple object tracking abilities with healthy aging. The temporal resolution of attention is known to limit attentional tracking of one and multiple targets (Holcombe & Chen, 2013). Here, we examined whether aging is associated with a lower temporal resolution of attention when tracking one target, the e...

A number of studies have shown that information is remembered better when it is processed for its survival relevance than when it is processed for relevance to other, non-survival-related contexts. Here we conducted three experiments to investigate whether the survival advantage also occurs for healthy older adults. In Experiment 1, older and younger adults rated words for their relevance to a ...

Family studies of exceptional longevity can potentially identify genetic and other factors contributing to long life and healthy aging. Although such studies seek families that are exceptionally long lived, they also need living members who can provide DNA and phenotype information. On the basis of these considerations, the authors developed a metric to rank families for selection into a family...

T elimination of health disparities in the United States is a national priority and overriding goal for Healthy People 2010 (HP 2010). Surveillance of health indicators among minority populations is essential to eliminating disparities. Surveillance is critical for program planning, policy making, evaluating population-based strategies, and tracking progress toward national and state objectives.

OBJECTIVE To review and update the most relevant research dealing with the antioxidant properties of fruits which can be useful in Mediterranean and other healthy diets. DESIGN Personal perspectives and late data. SETTING International. RESULTS The evaluation of total antioxidant capacity of fruits is of pivotal importance in assessing the nutritional attributes of these products. By mean...

The papers in this Special Issue compellingly show that older adults' everyday cognitive life is governed not by the decline in elementary cognitive processes as measured in the lab, but by a multitude of compensatory mechanisms, most of which are of the social/motivational variety. Much of this compensatory behavior can be elicited with no or only little experimental prodding, underscoring the...

introduction: health promoting lifestyle is one of the determinants of health. university years are important phase of life when one can develop health promoting lifestyle. given the high cost of healthcare there is need of shift from a treatment based approach to a preventive approach in which appropriate methods should be developed to promote health and productivity among youth. objective: th...

background: the role of individual healthy behaviors, like physical activity, nutrition and stress management, on reduction of the rate of disease mortality and morbidity is well known. the aim of this study is to determine the healthy life styles of teachers in district 4 of esfahan, iran, in 2010. methods: the participants of this cross-sectional study were 96 teachers in  district 4, selecte...
