Show Summary Details


This chapter discusses how we become aware of stimuli, focus our attention, and withdraw it. Topics covered include sensory awareness, spotlights and floodlights of attention, and habituation. It shows that the brain has a limited processing capacity and receives more information than it can process fully. People attend to stimuli that are important and ignore those that are unimportant. Stimulus significance is determined by their immediate needs (drives) and future goals.

Keywords: sensory awareness; habituation; spatial neglect; neglect; unilateral neglect; hemispatial neglect; extinction to simultaneous stimuli; line bisection test; cancellation test
