take data on student performance simultaneously with the teacher.

B.

compare student's self-graphed data to data collected by the teacher.

C.

compare data collected at the same time by the teacher and another teacher.

D.

compare her/his observation of a student's performance with data collected by the teacher from an earlier training session with the student.

Behavior that can be directly observed only by the person behaving is calleD.

A.

covert behavior.

B.

overt behavior.

C.

operant behavior.

D.

respondent behavior.

Data were collected on the percentage of intervals at the end of which Thomas was present at his workstation. Which is the BEST method for displaying these data?

A.

cumulative record

B.

equal-interval line graph

C.

scatterplot

A.

frequency.

B.

mastery.

C.

fluency.

D.

precision.

An establishing operation is any change in the environment whicH.

A.

momentarily alters the effectiveness of the consequence for a behavior that was previously followed by reinforcement.

B.

alters the timing of a behavior and momentarily alters the frequency of the behavior that was previously followed by reinforcement.

C.

alters the effectiveness of some object or event as reinforcement thus momentarily changing the likelihood of behavior that was previously followed by that reinforcer.

D.

alters the effectiveness of some object or event as a contingency-shaped rule and at the same time changes the momentary frequency of the behavior that was previously followed by reinforcement.

A parent reports that her 2-year-old daughter uses a number of stalling techniques to avoid bedtime once she is told to go to bed. What would be a good progress measure for going to bed when told?

A.

frequency

B.

inter-response time

C.

latency

D.

compliance

One of the MOST important reasons for writing a precise definition of behavior is that a precise definition:

A.

produces greater interobserver agreement and requires less training time for observers.

B.

allows for easier and more reliable quantification of temporal locus and temporal extent.

C.

increases the likelihood that the behavior of interest will be reliably detected by observers or measurement equipment.

D.

makes calibration checks of observers or measurement equipment less necessary.

In order to replace a behavior targeted for change with a behavior that topographically does not resemble the target behavior, which differential reinforcement procedure would be BEST?

A.

DRO

B.

DRH

C.

DRI

D.

DRL

A behavior analyst is working with an adult client, who is deemed competent. There are multiple potential behavior targets that need to be addressed including smoking cigarettes, nail biting, and compulsive hand washing. As a first goal, the behavior analyst wants the client to focus on eliminating smoking but the client would prefer to focus on nail biting. The behavior analyst shoulD.

A.

develop a self-management plan for eliminating nail biting as this is the preference of the client.

B.

develop a self-management plan for eliminating smoking as this behavior poses a serious health risk for the client.

C.

convince the client to change their first goal to elimination of smoking.

D.

refer the client to another behavior analyst as there is a discrepancy in goal setting priorities.

normalization.

B.

ethical treatment of consumers.

C.

consistency of instruction.

D.

spontaneous changes in intervention procedures.

D.

Tim learned to ask for help from his teacher and now can ask a fellow student for help.

If a client exhibits problem behaviors throughout the day and evenings regardless of what is going on in the environment and what activities he/she is participating in, which would be the BEST way to reduce the high frequency and increase latency?

A.

Use a differential reinforcement procedure for the absence of problem behaviors for an amount of time with a high magnitude reinforcer as a reward.

B.

Use a high magnitude punishment procedure every time he/she exhibits the problem behavior.

C.

Use a low magnitude punishment procedure every time he/she exhibits the problem behavior.

D.

Use a fixed ratio reinforcer every time he/she exhibits appropriate behavior.
