5 Written questions

5 Matching questions

  1. Face Validity
  2. Postsynaptic Receptors
  3. Construct
  4. Excitatory vs. Inhibitory
  5. Neuroimaging Techniques
  1. 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.
  2. 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)
  3. 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
  4. d variable we want to measure (e.g. intelligence)
  5. 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

  1. philosophers searched for answers using only logic and argumentation
  2. 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.
  3. 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
  4. Strength diminishes as it travels away. Graded potentials are cumulative
  5. Transmit information from the sensory receptors to the spinal cord and brain (afferent).

5 True/False questions

  1. Scientific Revolutionrejection of the older paradigm along with acceptance of the novel theory


  2. Alternate Form Reliabilityconsistency across time (does the test give similar values if the same person takes it 2 or more times?)


  3. Behaviorism Key Perspectives1. 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.


  4. Mental vs. PhysicalDo mental and physical events interact? (mind-body problem)


  5. Broca's Aphasiadamage to the left frontal lobe impairs the ability to produce fluent speech, but they could still understand language
