Language as grooming:
-Social bonding -small-talk -Efficient for large groups Mapping physical and social environment: -gossip Cooperation and planning Teaching and learning from others |
|
|
what is Chomsky's theory of syntax?
|
Universal deep structure of language
-innate, genetically hard-wired neural circuitry -each language group had unique transformational grammar leading to surface structure |
|
|
What are the components of language?
|
comprehension: phonetic, semantic, and syntactical processing
production: grammar and syntax, speech |
|
|
Decoding the meaning of sentences (syntax) relies on which areas?
|
pars triangularis and pars orbitalis (BA 45 and 47)
|
|
|
Speech depends on which areas?
|
posterior aspect of broca's area (BA 44), adjacent motor cortex (BA 6) and the insula
|
|
|
What technique has been used to study the projections of the arcuate fasciculus? what did it show
|
diffusion tensor imaging
|
most of the A.F. goes to the lexical semantic cortex |
|
how do macaque homologues of W + B areas compare to humans?
|
lateral superior temporal gyrus responsible for call processing (lesion makes them unable to distinguish between calls), but lesion in broca's homolog doesn't eliminate vocalization (proves that sounds are involuntary--simply expressions of arousal)
|
|
|
What did the study of the arcuate fasciculus in macaques vs humans show?
|
humans more extensive, associated with meaning
