Chapter 11 Positive Reinforcement Flashcards
Conditioned reinforcer
A previously neutral stimulus that has acquired the capability to function as reinforcer through stimulus-stimulus pairing with one or more unconditioned reinforcers or conditioned reinforcers
learned during an individuals lifetime
also called secondary reinforcer or learned reinforcer
generalized conditioned reinforcer
a conditioned reinforcer, that s a result of having been paired with many unconditioned and conditioned reinforcers, does not depend on a current EO for any particular form of reinforcement
positive reinforcement
occurs when a response is followed immediately by the presentation of a stimulus and, as a result, similar responses occur mor frequently in the future
positive reinforcer
the stimuls presented as a consequence and responsible for the subsequent increase in resonding
Premack principle
states that making the opportunity to engage in a behavior that occur at a relatively high free operant rate contingent on the occurrence of low-frequency behavior will function as reinforcement for the low-frequency behavior
reinforcer assessment
a variety of direct, data-based methods used to present one or more stimuli contingent on a target response and then measuring the future effects on rate of responding
response-deprivation hypothesis
a model for predicting if access to behavior functions as reinforcement for another behavior based upon the baseline rate of each behavior and whether access to the contingent behavior is a restriction compared to the baseline level of engagement
stimulus preference assessment
a variety of procedures used to determine the stimuli that a person prefers, the relative preference values of those stimuli, the conditions under which those preference values remain in effect, ad their presumed value as reinforcers
unconditioned reinforcer
a stimulus change that functions as reinforcement even though the learner has had no particular learning history with it.
the product of the evolutionary history of a species (phylogeny) and phylogenic development of species
also called primary reinforcer and unlearned reinforcer
motivating operants (MO)
environmental variables that
- alter the operant reinforcing effectiveness of some specific stimuli,objects, or events (the value altering effect)
- alter the momentary frequency of all behavior that ha ben reinforced by those stimuli, objects or event (the behavior-altering effect).
Establishing operation (EO)
An MO that increases the current effectiveness of a reinforcer
adding the EO to a discriminated operant results in a four-term contingency
basically EO determines what an individual want at any particular moment
ex. food deprivation makes food more effective as a reinforcer
Abolishig operaion (AO)
an MO tat decreases the current effectiveness of a reinforcer
EX. food ingestion reduces the effectiveness of food as a reinforcer
discriminative stimulus SD
an antecedent stimulus correlated with the availability of reinforcement for a particular response class
responding in the presence o the SD produces reinforcement, an responding in the SD absence (a conditioned called stimulus delta S^) does not
under stimulus control once a person learns to make more responses in the presence of the SD than in its absence
with the addition of the SD, the two-term contingency for reinforcement is transformed to the three-term contingency of the discriminated operant
free operant observation
observing and recording what activities the target person engages in hen she can choose during a period of unrestricted access to numerous activities
trial-based methods
stimuli are presented to the learner in a series of trials and the learner`s responses to the stimuli are measured as an index of preference
approach responses typically include any detectable movement by the person toward the stimulus, a contact is tallied each time the person touches or holds the stimulus, and engagement is a measure of the total time or percentage of observed intervals in which the person interacts with the stimulus
