unit 6 Flashcards
learning
the process of acquiring new and relatively enduring information or behaviors
habituation
an organism’s decreasing response to a stimulus with repeated exposure to it.
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.
cognitive learning
the acquisition of mental information, whether by observing events, by watching others, or through language.
classical conditioning
a type of learning in which one learns to link two or more stimuli and anticipate events.
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
neutral stimulus (NS)
in classical conditioning, a stimulus that elicits no response before conditioning
unconditioned response
in classical conditioning, an unlearned, naturally occurring response (such as salivation) to an unconditioned stimulus (US) (such as food in the mouth).
unconditioned stimulus
in classical conditioning, a stimulus that unconditionally—naturally and automatically—triggers a response (UR).
conditioned response
in classical conditioning, a learned response to a previously neutral (but now conditioned) stimulus (CS).
conditioned stimulus
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
in classical conditioning, the learned ability to distinguish between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus.
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
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
reinforcement
in operant conditioning, any event that strengthens the behavior it follows
shaping
an operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior.
discriminative stimulus
in operant conditioning, a stimulus that elicits a response after association with reinforcement (in contrast to related stimuli not associated with reinforcement).
positive reinforcement
increasing behaviors by presenting positive reinforcers. A positive reinforcer is any stimulus that, when presented after a response, strengthens the response
