Visual Working Memory
Visual working memory provide a key interface between perceptual processes and higher-level cognitive processes. Intriguingly, the capacity of visual working memory for simple features is strongly predictive of IQ and other measures of broad cognitive ability. Current topics of research include:
The nature of visual working memory representations and capacity limitations
The role of visual working memory as a buffer for non-automated cognitive operations
Impairments of visual working memory in people with schizophrenia
Neural mechanisms of visual working memory
The use of visual working memory to control the allocation of attention
Development of visual working memory in infancy
