PSYC 2200 EXAM 4 STUDY GUIDE
Negative Feedback - Answers - A process whereby the effect produced by an action
serves to diminish or terminate that action; a characteristic of regulatory systems.
Detector - Answers - In a regulatory process, a mechanism that signals when the
system variable deviates from its set point.
Set Point - Answers - Optimal value of the system variable in a regulatory mechanism.
Correctional Mechanism - Answers - In a regulatory process, the mechanism that is
capable of changing the value of the system variable.
Negative Reinforcement - Answers - The removal or reduction of an aversive stimulus
that is contingent on a particular response, with an attendant increase in the frequency
of that response
Stimulus-Response Learning - Answers - Learning to automatically make a particular
response in the presence of a particular stimulus; includes classical and instrumental
conditioning
Classical Conditioning - Answers - A learning procedure; when a stimulus that initially
produces no particular response is followed several times by an unconditional stimulus
that produces a defensive or appetitive response (unconditional response), the first
stimulus (conditioned stimulus) itself evokes the response (conditional response)
Hebb Rule - Answers - Hypothesis proposed by Donald Hebb that the cellular basis of
learning involves strengthening of a synapse that is repeatedly active when the
postsynaptic neuron fires
Instrumental Conditioning - Answers - Operant Conditioning, A learning procedure
whereby the effects of a particular behavior in a particular situation increase (reinforce)
or decrease (punish) the probability of the behavior
Motor Learning - Answers - Learning to make a new response; often involve interactions
with objects; bicycles, tennis racquets, knitting needles
Long-Term Potentiation - Answers - A long-term increase in the excitability of a neuron
to a particular synaptic input caused by repeated high frequency activity of that input
Population EPSP - Answers - An evoked potential that represents the EPSPs of a
population of neurons; measure of the strength of synaptic connections
