Unit 4: Learning Flashcards
Learning
The process of acquiring through experience new and relatively enduring information or behaviors
Habituation
Decreasing responsiveness with repeated exposure to a stimulus
Associative Learning
Learning that certain events occur together. The events may be two stimuli (as in classical conditioning) or a response and its consequence (as in operant conditioning)
Stimulus
Any event or situation that evokes a response
Respondent Behavior
Behavior that occurs as an automatic response to some stimulus
Operant Behavior
Behavior that operates on the environment, producing consequences
Classical Conditioning
A type of learning in which we link two or more stimuli; as a result, to illustrate with Pavlov’s classic experiment, the first stimulus ( a tone) comes to elicit behavior (drooling) in anticipation of the second stimulus (food)
Cognitive Learning
The acquisition of mental information, whether by observing events, by watching others, or through language
Behaviorism
The view that psychology (1) should be an objective science that (2) studies behavior without reference to mental processes. Most 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 (UR)
In classical conditioning, an unlearned, naturally occurring response (such as salvation) 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 an unconditioned 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 neutral stimulus, that after associating 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
Extinction
The diminishing of a conditioned response; occurs in classical conditioning when the 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 stimulus similar to the conditioned stimulus to elicit similar responses
Discrimination
(1) in classical conditioning, the learned ability to distinguish between a conditioned stimulus and similar stimuli that do not signal an unconditioned stimulus. (2) in operant conditioning, the ability to distinguish responses that are reinforced for similar responses that are not reinforced.
Operant Conditioning
A type of learning in which a behavior becomes more likely to recur if followed by a reinforcer or less likely to recur if followed by a punisher
Law of Effect
Thorndike’s principle that behaviors followed by favourable consequences becomes more likely, and that behaviors followed by unfavourable consequences becomes 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. EX clicker training
Discriminative Stimulus
In operant conditioning, a stimulus that elicits a response after association with reinforcement (in contrast to related stimuli not associated with reinforcement)
