The stimulus change responsible for the increase in responding is called a ________
reinforcer
A delay (as long as even one second) can ______________ that intended effects of a stimulus because it
allows for another, unintended stimulus to happen prior to the intended stimulus
diminish
In addition to increasing the future frequency of the behavior it follows (consequence stimuli),
____________ changes the function of antecedent stimuli.
reinforcement
This antecedent stimulus may evoke behavior because it is correlated with the availability of
reinforcement and is known as the _________________ ____________-
discriminative stimulus
The discriminative stimulus only signals the ______________ of a reinforcer. It does not change the
effectiveness of a reinforcer.
availability
A ____________ _____________ increases or decreases the current effectiveness of a reinforcer.
motivating operation
A motivating operation does not signal the _________________ of a reinforcer
availability
The refrigerator may typically signal the availability of food and food could be considered a
_____________ if you are hungry.
reinforcer

, Your hunger is not contingent on the availability of the refrigerator - it can happen anywhere. Your
hunger is considered a ______________ ______________
motivating operation
Your refrigerator may be available when you are not hungry. It is always there. Your refrigerator is
simply a signal for the availability of reinforcement, otherwise known as the ______________
__________
discriminative stimulus
_________________ ________________ are stimuli that function as reinforcement without requiring a
learning history.
Unconditioned reinforcers
These stimuli are the product of __________ development, meaning that all members of a species are
susceptible to the same properties of stimuli
phylogenic
_______________ ________________ are previously neutral stimuli that function as reinforcers as a
result of prior paring with one or more other reinforcers
conditioned reinforcers
A ___________________ is a conditioned reinforcer that has 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 for its effectiveness
generalized conditioned reinforcer
As Skinner pointed out, the powerful reinforcer "does not need to be ____________ for instructional
purposes; it is unrelated to any particular kind of behavior and hence always available. We call it
success"
contrived
An ______________________ is one in which responding terminates an ongoing aversive stimulus
escape contingency
An _______________ is one in which responding delays or prevents the presentation of an aversive
stimulus
avoidance contingency
In _______________________, responding in the presence of a signal prevents stimulus presentation
discriminated avoidance
In _____________________, responding at any time prevents stimulus presentation
free-operant avoidance
