STS responds to which body parts??
|
Eye movement
Mouth movement Hand movement Body movement |
|
|
|
What are the steps of the Haxby face processing model?
|
inferior occipital gyri (early perception of facial features) -- FFA (identity) -- intraparietal sulcus (spatially directed attention), auditory cortex (prelexical speech perception), amygdala, insula, limbic system (emotion) OR STS (expressions) --anterior temporal (personal identity, name, bio. info), extended system (processing with other systems)

|
What did single cell recordings of macaque face cells reveal? how does the visual cortex area differ in humans?
|
STS responds to specific expressions, cells responding to identity are instead in ITS
|
there's been a great expansion in language cortex on surface of human temporal lobes causing FFA to be pushed underneath the brain
|

Toxins, Infections, Mutations, Pathogens (TIMP)

Symmetry may indicate what in terms of human attractiveness?

|
|
Relatives to females faces, male faces have...?
|
Larger jaws
Larger brow ridges More prominent cheekbones Thinner lips More protuberant chin |
|
|
|
Pubertal effects on male and female face anatomy?
|
Testosterone in males
Lateral growth of cheekbones, mandible and chin Eyebrow ridges and central face grow forward Lower facial bones lengthen |
Estrogen in females
Caps growth of bony structures Enlargement of lips and upper cheeks by fat deposition |
|
|
What is the difference in how facial attractiveness that emerges in puberty is perceived between sexes?
|
Facial femininity that emerges in women at puberty is generally considered attractive. Facial masculinity that emerges at puberty may or may not be considered attractive, as a function of individual differences or hormonal factors
