Psychological Perspective
-syntax: grammatical rules
-semantics: meaning itself of the word
Syntax
-culturally dependant
-syntactic elements of speech are categorical
Transcranial Magnetic Simulation
-figure 8 device
-windings of copper wire. (200-300)
-snapping sound is made by capacitor discharging into the figure 8 coil. Pulses last 100 microsecond
-so much current passing through that the wires then a magnetic field will pass at opposite direction
-basically focused electro convulsive shock. Doesn’t pass current throughout the brain.
-TMS is only as good as you can think of a task that you can make the individual do whil you interfere
with the magnetic pulse
Converging evidence
-location of singing and speaking are different.
-imaging studies allow us to intervene in subjects
-subtraction method: taking the difference between two brain states (experimental to control). This will
to you the activity difference between both states. Even during control states the brain is still active
-PET: patients inhaling fluorine. Needs a nuclear reactor to create the isotopes
-showing the infero temporal cortex. Different locations associated with naming different types of things
