Ability to recognize an object in countless situations
object constancy
This part of the brain is critical for shape and object recognition
lateral occipital cortex (LOC)
can recognize an object, but cannot tell you what can be done with it
Optic Ataxia
This attention network helps us stay alert
ventral attention network
all input are processed equally and selection follows to determine what will undergo additional awareness
late selection model
This refers to predicting the stimulus that being viewed when a particular brain state is being viewed
decoding
Bilateral damage to the posterior parietal and occipital cortex results in
baliant's syndrome
With visual agnosia, there is damage to which stream?
ventral stream
Unilateral neglect is commonly seen as damage to which hemisphere
right hemisphere
this theory suggests that object recognition occurs due to the collective activation of multiple units
ensemble coding hypothesis
Selective attention
Spacial processing proceeds ____, while object identification proceeds _____
dorsally; ventrally
Damage to the right hemisphere can lead to the inability to perceive an object as a whole
integrative agnosia
Sensorimotor areas helps us identify what type of objects
inanimate
endogenous attention is also known as
voluntary attention
Can be described as a bottom- up, stimulus driven process
Reflexive Attention
Damage or abnormalities in this part of the brain causes a deficit in recognizing faces
fusiform gyrus
unilateral neglect results in
disturbances of spacial attention (ignoring one side)
The ventral stream gets input from which pathways
parvocellular pathways
This condition is usually modality specific
agnosia
A deficiency in Baliant syndrome that affects perceiving the visual field as a whole scene
simultanagnosia
What brain regions make up the attentional control mechanism?
VSP TPS (Very Small Puppies Try Playing Soccer)
V- Ventral prefrontal
S- superior prefrontal
P- posterio- parietal
T- temporal- parietal junction
P- pulvinar of thalamus
S- superior colliculus
Tests used to identify apperceptive agnosia
shadow test & unusual view test
Damage here results in the loss of knowing what to do with an object and knowing where it is
dorsal stream
Sally is looking at her book, however is listening to the tea being spilled by the group of girls behind her. This is an example of what type of attention
covert attention
