Document Summary
Able to correct identify the stimulus when only one stimulus is present another stimulus: difficulty with simultaneous identification of two stimuli, symptoms of neglect extinction (suppression of perceptual response to a stimulus by. Two simultaneous stimuli only identify the stimulus in the right visual field and. Perceptual response to one stimulus (cid:498)extinguishes(cid:499) response to the other. Late selection theory only one signal can get through the filter to consciousness at. Extinction two competing perceptual representations cannot co-exist (one of the. Damaged hemisphere chronically underactive, stimuli don"t provide activation as. Recognition and identification require the activation of neural structures: people are usually poor in identifying two weak, simultaneous signals perceptual representations is projected to a damaged hemisphere) they should a time. Effects strongest with activity in other hemisphere (invalid cue, competing stimulus: balint"s syndrome (cid:523)super neglect(cid:524, occurs even when objects overlap -> object based, space-based vs. object-based attention, bilateral lesions in parietal and/or occipital cortex.
