Summary
This summary is machine-generated.

Visual extinction, a deficit in attention, can occur with successive stimuli. A competitive model of visual selective attention better explains this phenomenon than attention disengagement theories.

Background:

  • Visual extinction is a spatial attention disorder with unclear pathogenic mechanisms.
  • Hypotheses include impaired attention disengagement or reduced competition for visual selection.
  • Understanding extinction's mechanism is crucial for treating attention deficits.
