p. 846. Perception and actionlocked

  • Brian Rogers


Perceptual processes have evolved to allow us to act appropriately. ‘Perception and action’ explains that the strong link between perception and action has been revealed in a variety of relatively low-level tasks such as helping us to maintain balance; providing information about our movements within the world (self-motion); allowing us to determine our direction of travel (heading); and helping us to estimate the time before we reach objects in the surrounding world (time-to-contact). James Gibson has suggested that the purpose of our perceptual systems is not to identify objects as objects, but rather to extract information about what we might do with those objects and how we might respond to events in the world.
