Structuralism
DEFINITION 2 Edward Titchner task of psych= analyze basic elements of consciousness and investigate how elements are related TERM 3
Functionalism
DEFINITION 3 William James task of psych= to find function/purpose of consciousness, not structure American attitude: just tell us how it works so that we can make money off of it from Darwinism TERM 4
Behaviorism
DEFINITION 4 John B, Watson observable behavior pro nurture focuses only on behavior, not mind Skinner box TERM 5

Spatial
how precise in area TERM 17
Trans-cranial Magnetic Stim. (TMS)
DEFINITION 17 creates virtual lesion on brain decreases electrical activity in area of brain uses magnet to knock out specific neurons to see how behavior would change PROS: easy to do, noninvasive CONS: very temporary, could induce seizures, can't access lower brain TERM 18
EEG
DEFINITION 18 electrodes sendelectricalactivity toamplifier event related potential: uses EEG, zooms in to 1 sec. segments, finds average activity across trials hit: when subjects succeed in relating everything miss: opposite of hit much better temporal than fMRI PROS: cheap, spatial CONS: no causation and no specific location TERM 19
Neuroimaging Techniques Structural
DEFINITION 19 Computer AxialTomography(CAT) use x-ray on single axis to generate 3D picture of brain MRI both can find diseases TERM 20
Functioning Neuroimaging Tech.
DEFINITION 20 Position Emission Tomography (PET) radioactive glucose injected into patient scanner detects glucose and detects how it is used PRO: color image CON: expensive, ingesting radioactive is bad fMRI tracks blood flow color, huge magnet expensive

synapses of an adult?
TRUE
TERM 22
Neural Darwinism
DEFINITION 22 natural selection for synapses of the brain surplus of synapses use pathway => strengthen disuse? pruning then occurs to increase efficiency of rest TERM 23
