Chapter 6 Flashcards
visual inputs
low level inputs are turned into high level precepts
object recognition
memory based and object unified
object constancy
ability to perceive an object as the same, even though the visual perspective is different
ventral (what) pathway
object recognition and perception
dorsal (where) pathway
spatial perception
auditory pathway
separation of dorsal (where) and ventral (what)
inferior temporal cortex
cells respond to meaningful object recognition; FFA, PPA
FFA (fusiform face area)
responds most strongly to faces
PPA (parahippocampal place area)
responds most strongly to places and scenes
agnosia
inability to process information even though sensory organ and memory are intact
visual agnosia *
the inability to visually recognize objects despite otherwise normal vision
auditory agnosia
inability to recognize music even though hearing is intact
optic ataxia
able to recognize objects but unable to visually coordinate movements to interact with object
repetition suppression
efficiency of the brain by showing diminished neural activity in response to repeated stimulus
fNIRS (functional near-infrared spectroscopy)
measures differential near-infrared light absorption properties of oxy- and deoxyhemoglobin to detect the concentration changes related to focal brain activity (related to repetition suppression)
