Chapter 7 Flashcards
Behaviorism
Psychology (1) should be an objective science that
(2) studies behavior without reference to mental
processes.
Most research psychologists today agree with (1) but
not with (2).
Classical conditioning:
Type of learning in
which one learns to link two or more stimuli and
anticipate events
Neutral stimulus (NS)
: A stimulus that
unconditionally—naturally and automatically—
triggers an unconditioned response (UR)
Conditioned response (CR):
A learned
response to a previously neutral but now
conditioned stimulus (CS)
Conditioned stimulus (CS): An originally neutral
stimulus that, after association with an
unconditioned stimulus (US), comes to trigger a
conditioned response (CR)
Unconditioned response (UR): An unlearned,
naturally occurring response (such as salivation) to
an unconditioned stimulus (US) (such as food in the
mouth)
Unconditioned stimulus (US): A stimulus that
unconditionally—naturally and automatically—
triggers an unconditioned response (UR)
Acquisition
Initial stage, when one links a neutral stimulus and an
unconditioned stimulus so that the neutral stimulus
begins triggering the conditioned response
In operant conditioning, the strengthening of a
reinforced response
igher-order conditioning
A procedure in which the conditioned stimulus in one
conditioning experience is paired with a new neutral
stimulus, creating a second (often weaker)
conditioned stimulus
An animal that has learned that a tone predicts food
might then learn that a light predicts the tone and
begin responding to the light alone.
Also called second-order conditioning
extinction
Diminishing of a conditioned response
Occurs in classical conditioning when an
unconditioned stimulus (US) does not follow a
conditioned stimulus (CS
Spontaneous recovery
Reappearance, after a pause, of an extinguished
conditioned response
Generalization
Tendency, once a response has been conditioned, for
stimuli similar to the conditioned stimulus to elicit
similar responses
Discrimination
Learned ability to distinguish between a conditioned
stimulus (which predicts the unconditioned stimulus)
and other irrelevant stimuli
Edward L. Thorndike
Law of effect: Principle that behaviors followed by
favorable consequences become more likely and that
behaviors followed by unfavorable consequences
become less likely
B. F. Skinner
Operant chamber (Skinner box): A chamber
containing a bar or key that an animal can manipulate
to obtain a food or water reinforcer; attached devices
record the animal’s rate of bar pressing
