- Face Validity
- Postsynaptic Receptors
- Excitatory vs. Inhibitory
- Neuroimaging Techniques
- a Excitatory: depolarize the membrane (open sodium channels) making an action potential more likely
Inhibitory: hyperpolarize the membrane (open potassium channels) making an action potential less likely.
- b whether or not the test appears, just by looking at it, as though it assesses what it purports to assess (researcher doesn't want face validity b/c participants may change responses; least important type of validity)
- c CT (computerized tomography)- uses x-rays
MRI (magnetic resonance imaging)- static picture
PET (positron emission tomography)- radioactive glucose to map for high and low activity
fMRI (functional)- magnets to watch brain function
- d variable we want to measure (e.g. intelligence)
- e protein molecules that act like "locks" that can be opened only by specific neurotransmitter "keys" Binding: opens or closes ion channels
5 Multiple choice questions
- philosophers searched for answers using only logic and argumentation
- Representative Sampling of the population as a whole so that conclusions that are drawn from the sample are likely to be true of the rest of the population.
- produced in the substantia nigra and released in to the nucleus accumbens (pleasure/reward) or the basal ganglia (voluntary movement;attention)
Schizophrenia- too much DA
Parkinson's- not enough DA (treated with L-dopa b/c DA can't be given directly b/c it doesnt cross the blood-brain barrier
- Strength diminishes as it travels away. Graded potentials are cumulative
- Transmit information from the sensory receptors to the spinal cord and brain (afferent).
5 True/False questions
Scientific Revolution → rejection of the older paradigm along with acceptance of the novel theory
Alternate Form Reliability → consistency across time (does the test give similar values if the same person takes it 2 or more times?)
Behaviorism Key Perspectives → 1. Environmentalism: all organisms, including humans, are shaped by the environment. 2. Experimentalism: experiments can reveal what aspects of the environment stimulate. 3. Optimism: people can be positive.
Mental vs. Physical → Do mental and physical events interact? (mind-body problem)
Broca's Aphasia → damage to the left frontal lobe impairs the ability to produce fluent speech, but they could still understand language
