Unit Five: Learning Flashcards
Learning
the process of acquiring new and relatively enduring information or behaviors
Habituates
make or become accustomed or used to something
Associative learning
learning that certain events occur together. The events may be two stimuli (as in classical conditioning) or a response and its consequences (as in operant conditioning)
Stimulus
any event or situation that evokes a response
Conditioning
process of learning associations
Classical conditioning
we learn to associate two stimuli and thus to anticipate events
Operant conditioning (what we associate)
we learn to associate a response (our behavior) and its consequence. Thus we (and other animals) learn to repeat acts followed by good results and avoid acts followed by bad results
Cognitive learning
the acquisition of mental information, whether by observing events, by watching others, or through language
Observational learning
one form of cognitive learning, lets us learn from others’ experiences
Behaviorism
the view that 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)
Ivan Pavlov
classical conditioning
John B. Watson
psychology should be an objective science based on observable behavior (behaviorism)
Neutral stimuli (NS)
events that an animal can see or hear but do not associate with any event
Unconditioned response (UR)
in classical conditioning, an unlearned, naturally occurring response (such as salivation) to an unconditioned stimulus (US) (such as food in the mouth
Unconditioned stimulus (US)
in classical conditioning, a stimulus that unconditionally—naturally and automatically—triggers a response (UR)
Conditioned response (CR)
in classical conditioning, a learned response to a previously neutral (but now conditioned) stimulus (CS
Conditioned stimulus (CS)
in classical conditioning, an originally irrelevant stimulus that, after association with an unconditioned stimulus (US), comes to trigger a conditioned response (CR)
Acquisition
in classical conditioning, the 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
Higher-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. For example, 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
the diminishing of a conditioned response; occurs in classical conditioning when an unconditioned stimulus (US) does not follow a conditioned stimulus (CS); occurs in operant conditioning when a response is no longer reinforced
Spontaneous recovery
the reappearance, after a pause, of an extinguished conditioned response
Generalization
the tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similar responses
Discrimination
(1) in classical conditioning, the learned ability to distinguish between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus. (2) in social psychology, unjustifiable negative behavior toward a group and its members
Respondent behavior
actions that are automatic responses to a stimulus (such as salivating in response to meat powder and later in response to a tone)
Operant conditioning (strengthened/diminished)
operant conditioning: a type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher
Law of effect (scientist)
Thorndike’s principle that behaviors followed by favorable consequences become more likely, and that behaviors followed by unfavorable consequences become less likely
Operant chamber
in operant conditioning research, a chamber (also known as a Skinner box) 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 or key pecking
