The stimulus change responsible for the increase in responding is
called_____________ - ANS ✓Reinforcement
A delay can_________the intended effects of a stimulus because it allows for
another unintended stimulus to happen prior to the intended stimulus -
ANS ✓Change
In addition to increasing the future frequency of the behavior it
follows_________changes the function of antecedent stimuli - ANS
✓Reinforcement
This antecedent stimuli may evoke behavior because it is correlated with
the availability of reinforcement and is known as the___________________ - ANS
✓Discriminative stimulus (SD)
The discriminative stimulus only signals the____________of a reinforcer. It
does not change the effectiveness of the reinforcer. - ANS ✓Availability

A__________increases or decreases the current effectiveness of a reinforcer. It
does not signal the occurrence of a reinforcer - ANS ✓MO (motivating
operation)
The refrigerator may typically signal the availability of food and food could
be considered a______________if you are hungry - ANS ✓Reinforcer
Your hunger is not contingent on the availability of the refrigerator and can
happen anywhere. Your hunger is considered a______________ - ANS
✓Motivating operation (MO)(EO)
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__________________ - ANS ✓Discriminative
stimuli
___________________are simply stimuli that function as reinforcement without
requiring any learning history. - ANS ✓Unconditioned reinforcers
_______________are previously neutral stimuli that function as reinforcers as a
result of prior pairing with one or more other reinforcers - ANS
✓Conditioned reinforcers
A__________________is a conditioned reinforcer that as a result of having paired
with many unconditioned and conditioned reinforcers does not depend on
a current EO or any particular form of reinforcement for its effectiveness -
ANS ✓Generalized conditioned reinforcer
As Skinner pointed out, the powerful reinforcer does not need to
be_________for instructional purposes - ANS ✓Contrived
An____________is one in which responding terminates an ongoing aversive
stimulus - ANS ✓Escape contingency

EDF
An______is one in which responding delays or prevents the presentation of
an aversive stimulus - ANS ✓Avoidance contingency
In_________responding in the presence of a signal prevents stimulus
presentation - ANS ✓Discriminated avoidance
In________responding at any time prevents stimulus presentation - ANS
✓Free-operant avoidance
Removal and reduction of ongoing stimulation typically produce behavior
that is called_______ - ANS ✓Escape
Postponement and prevention of stimulus presentation produce behavior
that is called__________ - ANS ✓Avoidance
Escape_____________as an intervention may actually backfire and shape more
dangerous behavior - ANS ✓Maintained behavior
According to Ruddle positively reinforced behavior may compete with but
will not suppress________respoding that is reinforced concurrently - ANS
✓Escape
According to Iwata_______might be considered more intrusive than
punishment because with negative reinforcement presentation of the
aversive stimulus is contingent on the absence rather than the occurrence
of behavior - ANS ✓Negative reinforcement
Punishment has occurred when a stimulus change immediately follows a
response and_________the future frequency of that type of behavior in similar
conditions - ANS ✓Decreases
