Vision in complex environments requires observers not only to detect and discriminate
stimuli presented si multaneously, but also to integrate information appro priately over space …

Recent evidence suggests that the mature human brain is capable of substantial functional
reorganization following injury. The fact that the brain retains a great deal of plasticity raises …

Using fMR adaptation, we studied the effects of aging on the neural processing of passively
viewed naturalistic pictures composed of a prominent object against a background scene …

With the percentage of older adults in our society on the increase, there is a pressing need
to better understand the functional problems of the elderly, and to identify ways in which the …

The identification of objects and events in the environment depends on a variety of
information-processing mechanisms that extend over time, however briefly. Consequently …

Visual episodic recognition memory was assessed in young (mean age 22.5 years) and
older (mean age 74.1 years) participants. To isolate purely visual memory, recognition was …

Memory for semantic information is relatively preserved through the normal aging process.
Visuospatial memory remains less intact. In the present article a theory is proposed that links …

Healthy aging is associated with a decline in basic perceptual abilities, as well as higher-
level cognitive functions such as working memory. In a recent perceptual training study …

The perception of a visual stimulus can be markedly altered by spatial interactions between
the stimulus and its surround. For example, a grating stimulus appears lower in contrast …

The performance of many cognitive tasks changes in normal aging [1–3]. Recent behavioral
work has identified some tasks that seem to be performed in an age-invariant manner [4]. To …
