learning
the process of acquiring new and relatively enduring information or behaviors.
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).
social learning theory
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 (UCR)
in classical conditioning, an un-learned, naturally occurring response (such as salivation) to an unconditioned stimulus (US) (such as food in the mouth).
unconditioned stimulus (UCS)
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). (Myers Psychology for AP 2e p. 268)
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.
observational learning
learning by observing others. (Also called social learning.)
modeling
the process of observing and imitating a specific behavior.
cognitive map
a mental representation of the layout of one's environment. For example, after exploring a maze, rats act as if they have learned a cognitive map of it.
latent learning
learning that occurs but is not apparent until there is an incentive to demonstrate it.
insight
a sudden realization of a problem's solution; contrasts with strategy-based solutions.
learned helplessness
the hopelessness and passive resignation an animal or human learns when unable to avoid repeated aversive events. (Myers Psychology for AP 2e p. 299)
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. (Myers Psychology for AP 2e p. 276)
shaping
an operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior. (Myers Psychology for AP 2e p. 276)
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.
negative reinforcement
increasing behaviors by stopping or reducing negative stimuli. A negative reinforcer is any stimulus that, when removed after a response, strengthens the response. (Note: Negative reinforcement is not punishment.)
primary reinforcer
an innately reinforcing stimulus, such as one that satisfies a biological need.
secondary or conditioned reinforcer
a stimulus that gains its reinforcing power through its association with a primary reinforcer; also known as a secondary reinforcer.
continuous reinforcement
reinforcing the desired response every time it occurs.
partial (intermittent) reinforcement
reinforcing a response only part of the time; results in slower acquisition of a response but much greater resistance to extinction than does continuous reinforcement.
fixed-ratio schedule
in operant conditioning, a reinforcement schedule that reinforces a response only after a specified number of responses.
variable-ratio schedule
in operant conditioning, a reinforcement schedule that reinforces a response after an unpredictable number of responses.
fixed-interval schedule
in operant conditioning, a reinforcement schedule that reinforces a response only after a specified time has elapsed.
variable-interval schedule
in operant conditioning, a reinforcement schedule that reinforces a response at unpredictable time intervals.
punishment
an event that tends to decrease the behavior that it follows.
positive punishment
the administration of a stimulus to decrease the probability of a behavior's recurring
negative punishment
the removal of a stimulus to decrease the probability of a behavior's recurring
instinctive drift
tendency for animals to return to innate behaviors following repeated reinforcement
taste aversion
a type of classical conditioning in which a previously desirable or neutral food comes to be perceived as repugnant because it is associated with negative stimulation
Robert Rescorla
researched classical conditioning; found subjects learn the predictability of an event through trials (cognitive element)
Escape learning (negative reinforcement)
an organism acquires a response that decreases or ends some aversive stimulation
Avoidance Learning (Negative Reinforcement)
the removal of or avoiding an unpleasant consequence following a desired behavior
Premack Principle
commonly occurring/desirable behavior can reinforce a less frequent/undesirable behavior
Albert Bandura
pioneer in observational learning (AKA social learning), stated that people profit from the mistakes/successes of others; Studies: Bobo Dolls-adults demonstrated 'appropriate' play with dolls, children mimicked play
Insight Learning (Kohler)
Chimps problem solving occurs by means of a sudden reorganization/realization of perception - completely cognitive
