3 assumptions of level systems - Correct Answer - combined techniques
are more effective than individual contingencies introduced alone,
student behaviors and expectations must be stated explicitly, and
differential reinforcement is necessary to reinforce closer and closer
approximations to the next level
designing a token economy - Correct Answer - 1. identify target
behaviors and rules: select only measurable and observable behaviors;
specify criteria for task completion; make sure learners have prerequisite
skills
2. select tokens
3. develop a menu of backup reinforcers
4. establish a token exchange ratio: the initial ratio between tokens
earned and the price of backup reinforcers should be small
5. determine how the tokens will be dispensed
6. determine how the tokens will be exchanged: token exchange should
be available frequently, then thinned
,7. specify what happens if token requirements are not met: reinstate the
contingency: "I'm sorry, you haven't earned enough tokens at this time.
try again". response costs can be included
8. field-test the system
chronic rule breakers in token economies - Correct Answer - ensure the
tokens function as a generalized conditioned reinforcer, conduct a
reinforcer assessment to determine that the backup reinforcers function
as reinforcers and are preferred by each of the students, and applying
alternative procedures. programs can be modified so that tokens are
combined with a DRA procedure, extinction, or brief time-out
withdrawing a token economy - Correct Answer - plan for descriptive
verbal praise to take the place of the tokens. the number of responses
required to earn a token should be gradually increased. the duration the
token economy is in effect should be gradually decreased. the number of
activities and privileges that serve as backup items and are likely to be
found in the untrained setting should be increased gradually. items
should be introduced that would be common in a regular class (e.g., gold
stars). the price of more desirable items should be increased
systematically while keeping a very low price on less desirable items for
exchange. the physical evidence of the tokens should be faded over
time
group contingency - Correct Answer - a common consequence is
contingent on the behavior of one member of the group, the behavior of
, part of the group, or the behavior of everyone in the group. can be used
in cases in which the practitioner must resolve a problem quickly, as
when serious disruptive behavior occurs
independent group contingencies - Correct Answer - an arrangement in
which a contingency is presented to all members of a group, but
reinforcement is delivered only to those group members who meet the
criterion outlined in the contingency. frequently combined with
contingency contracting and token reinforcement schedule
dependent group contingencies (hero procedure) - Correct Answer - the
reward for the whole group is dependent on the performance of an
individual student or small group. if the individual or small group
performs a behavior to criterion, the group shares the reinforcer. if not,
the reinforcer is not delivered
interdependent group contingencies - Correct Answer - all members of a
group must meet the criterion of the contingency before any member
earns the reward
contingency contracting (behavioral contract) - Correct Answer - a
document that specifies a contingent relationship between the
completion of a target behavior and access to, or delivery of, a specified
reward. make one person's behavior dependent on the other person's
behavior
