Age-Related Changes, Optical Factors, and Neural Processes
The eye makes two different but equally important contributions to vision: optical and neural. In the first contribution, various surfaces and structures admit light into the eye and focus it on the retina's specialized photosensitive elements (rods and cones). In the second contribution. a complex, organized network of neurons processes signals generated by photoreceptor transduction of light,...
متن کاملIs Fitts’ Law Continuous in Discrete Aiming?
The lawful continuous linear relation between movement time and task difficulty (i.e., index of difficulty; ID) in a goal-directed rapid aiming task (Fitts' law) has been recently challenged in reciprocal performance. Specifically, a discontinuity was observed at critical ID and was attributed to a transition between two distinct dynamic regimes that occurs with increasing difficulty. In the pr...
متن کاملAge-Related Changes in Sleep and Circadian Rhythms: Impact on Cognitive Performance and Underlying Neuroanatomical Networks
Circadian and homeostatic sleep-wake regulatory processes interact in a fine tuned manner to modulate human cognitive performance. Dampening of the circadian alertness signal and attenuated deterioration of psychomotor vigilance in response to elevated sleep pressure with aging change this interaction pattern. As evidenced by neuroimaging studies, both homeostatic sleep pressure and circadian s...
متن کاملAge-related dedifferentiation and compensatory changes in the functional network underlying face processing.
Recent evidence has shown that older adults fail to show adaptation in the right fusiform gyrus (FG) to the same face presented repeatedly, despite accurate detection of the previously presented face. We used functional magnetic resonance imaging to investigate whether this phenomenon is associated with age-related reductions in face specificity in brain activity and whether older adults compen...
متن کاملAre age-related changes in cognitive function driven by age-related changes in sensory processing?
Although there has been keen interest in the association among measures of sensory function and cognitive function for many years, in general, measures of sensory function have been confined to one or two senses and measures of threshold sensitivity (acuity). In this study, rigorous psychophysical measures of threshold sensitivity, temporal gap detection, temporal order identification, and temp...
