Jamie frequently falls to the floor and screams at school. Preliminary behavioral assessment data indicate that his tantrums are maintained by attention and escape from demand situations. Jamie's behavior analyst wants to examine precisely how attention and escape conditions affect these behaviors. The behavior analyst does not want to conduct the analysis in Jamie's classroom because she would not be able to control for potentially important factors. Relating to this scenario, which statement is TRUE?

A.

Analyses that involve experimental conditions are almost always conducted in the person's natural environment.

A.

are similar in content.

B.

consistently co-vary.

C.

occur at the same rate.

D.

occur simultaneously.

Behavioral contracts must includE.

A.

a summary of the functional assessment; the target behavior; and the consequences for its occurrence and non-occurrence.

B.

vocal descriptions of how the behavior is to be measured; the consequences for its occurrence and non-occurrence; the contract manager; and the target behavior.

C.

written descriptions of how the behavior is to be measured; when behavior must occur; the consequences for its occurrence and non-occurrence; the contract manager; and the target behavior.

D.

a summary of the functional assessment; written descriptions of how the behavior is to be measured; when behavior must occur; the contract manager; and the target behavior.

Imitation training can be made MOST beneficial for clients when it includes a range oF.

A.

models.

B.

prompts.

C.

reinforcers.

D.

settings.

A behavioral assessment indicates that the problem behavior of a young woman is maintained by others bringing things to her or taking things away following occurrence of the behavior. Since the behavior results in physical injury, the decision to decrease its occurrence has been made. Which is the BEST general approach?

A.

Determine a potential punisher and deliver it following every occurrence of the behavior, but do not provide or remove other things following the occurrence.

B.

Prevent the behavior by physically blocking each response.

C.

Stop providing or removing things following the behavior and allow it to undergo extinction.

D.

Use protective equipment that prevents injury and establish a replacement behavior that results in things being provided to or removed from the woman.

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.

moving activities to locations where maladaptive behaviors are highly unlikely to occur.

C.

planning to ignore the target behavior within all environments.

prefacing hard tasks with easy tasks.

does not permit the precise determination of functional relationships.

C.

provides a less than adequate description of the topography and intensity of behavior.
