23
Q

geons

A

24
Q

NAPs

A

25
semantic regularities
functions in scenes
26
theory of unconscious inference
using knowledge to infer what is present in a scene
27
Fusiform Face Area
perceives faces. Contains amygdala (emotions) // superior temporal sulcus (mouth movements) // frontal cortex (evaluating appearance)
28
extrastriate body area
perceives bodies
29
parahippocampal place area
perceives places
30
grill spector experiment
face and then mask and you are asked what you see
31
Tong and Coworkers experiment
One eye you see a house, other a face. When you see the house the parahippocampal place area is activated and when you see the face the Fusiform face area is activated
