OBJECTIVES This study examined the impact of context information on emotion recognition from a life-span developmental perspective. The main prediction was that age-related deficits in emotion recognition will only be evident in context-poor tasks. METHODS A sample of 48 younger (M(age) = 23 years) and 35 older women (M(age) = 70 years) watched 48 film(More)
Previously, we found that during films about age-typical losses, older adults experienced greater sadness than young adults, whereas their physiological responses were just as large. In the present study, our goal was to replicate this finding and extend past work by examining the role of cognitive functioning in age differences in emotional reactivity. We(More)
This study investigated age differences in cognitive and affective facets of empathy: the ability to perceive another's emotions accurately, the capacity to share another's emotions, and the ability to behaviorally express sympathy in an empathic episode. Participants, 80 younger (M(age) = 32 years) and 73 older (M(age) = 59 years) adults, viewed eight film(More)
Giardia trophozoites attach to the intestinal microvilli (or inert surfaces) using an undefined "suction-based" mechanism, and remain attached during cell division to avoid peristalsis. Flagellar motility is a key factor in Giardia's pathogenesis and colonization of the host small intestine. Specifically, the beating of the ventral flagella, one of four(More)
OBJECTIVES Older adults more often complain about sleep disturbances compared with younger adults. However, it is not clear whether there is still a decline of sleep quality after age 60 and whether changes in sleep quality in old age are mere reflections of impaired physical health or whether they represent a normative age-dependent development.

Using cross-sectional and longitudinal data from a national sample spanning the adult life span, age differences in anger and sadness were explored. The cross-sectional and longitudinal findings consistently suggest that the frequency of anger increases during young adulthood, but then shows a steady decrease until old age. By contrast, the frequency of(More)
The effect of initial microstructural deformation, alignment, and morphology on the response of wormlike micelle solutions in transient uniaxial extensional flows is investigated using a pre-shear device attached to a filament stretching rheometer. In filament stretching experiments, increasing the strength and the duration of the pre-shear just before(More)
At Re = 3900, Newtonian flow past a circular cylinder exhibits a wake and detached shear layers which have transitioned to turbulence. It is the goal of the present study to investigate the effects which viscoelasticity has on this state and to identify the mechanisms responsible for wake stabilization. It is found through numerical simulations (employing(More)
Objectives. This study examined the impact of context information on emotion recognition from a lifespan developmental perspective. The main prediction was that age-related deficits in emotion recognition will only be evident in context-poor tasks. Methods.

Using a code developed to compute high Reynolds number visco-elastic flows, polymer injection from the upstream stagnation point of a circular cylinder is modeled at Re ¼ 3900. Polymer stresses are represented using the FENE-P constitutive equations. By increasing polymer injection rates within realistic ranges, significant near wake stabilization is(More)
