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
