Exam 3: Terms Flashcards
Operant Conditioning
a procedure in which a behavior becomes stronger or weaker (is more likely to happen) depending on its consequences.
Extinction
when a desired consequence is discontinued, the behavior producing that consequence will be weakened. E.g. when lever pressing no longer leads to food, rats will decrease lever pressing behavior.
Spontaneous Recovery
a previously extinguished behavior returns if there is a break in training. E.g. if rats who no longer lever press are removed from the experimental apparatus for 24 hours, lever pressing will return.
Discrete Trial Procedure
a procedure where the behavior of the participant ends the trial.
Free Operant Procedure
a procedure where the behavior of the participant can be repeated many times.
Reinforcement
the rate or probability of the occurrence of a behavior is increased when something (a reinforcer) is presented or removed following the behavior.
Punishment
the rate or probability of the occurrence of a behavior is decreased when something (a punisher) is presented or removed following the behavior.
Positive Reinforcement
behavior is strengthened when it is followed by the appearance of (or an increase in the intensity of) a stimulus, or positive reinforcer
Negative Reinforcement
behavior is strengthened when it is followed by the removal of (or a decrease in the intensity of) a stimulus, or negative reinforcer.
Positive Punishment
behavior is weakened when it is followed by the appearance of (or an increase in the intensity of) a stimulus, or positive punisher.
Negative Punishment
behavior is weakened when it is followed by the removal of (or a decrease in the intensity of) a stimulus, or negative punisher.
Establishing Operations
a procedure that produces a change in an individual’s environment that alters how effectively something functions as a reinforcer.
Primary (unconditioned) Reinforcers
stimuli that are innately reinforcing (no learning required), such as food, water, sex, social contact, relief from temperature extremes, drugs etc.
Secondary (conditioned) Reinforcers
stimuli that are reinforcing because of their association with other reinforcers (including other secondary reinforcers). These include praise, recognition, smiles, money etc.
Shaping
reinforcing successive approximations of the target behavior.
