EXAM ACCURATE QUESTIONS AND
ANSWERS WITH RATIONALES | VERIFIED
AND LATEST UPDATED |
GUARANTEED PASS
1. A __________________ study seeks to discover the differential effects of a
range of values on the independent variable on the dependent variable of
interest.
A. Nonparametric
B. Descriptive
C. Parametric ✅
D. Functional
Rationale: A parametric study examines how different levels of an
independent variable affect behavior, determining the effect of intensity or
magnitude.
2. Single-subject research designs always involve a single participant.
A. True
B. False ✅
Rationale: Multiple participants can be used in single-subject designs; each is
treated as a separate experimental unit.
3. Baseline data collection is important because it results in a certain level of
needed subjectivity.
, A. True
B. False ✅
Rationale: Baseline data collection aims to establish an objective measure of
behavior before intervention.
4. All experiments in ABA include at least one behavior and at least one
treatment or intervention condition.
A. True ✅
B. False
Rationale: These are fundamental components in demonstrating a functional
relationship in ABA.
5. This design compares two or more distinct treatments while their effects
on the target behavior are measured.
A. Multiple baseline design
B. Changing criterion design
C. Alternating treatments design ✅
D. Reversal design
Rationale: Alternating treatments design rapidly alternates between
conditions to compare their effects.
6. Which of the following is considered a limitation in the use of a multiple
treatment reversal design?
A. Experimental control
B. Sequence effects ✅
C. Generalization
, D. Low baseline variability
Rationale: Sequence effects may occur when one treatment influences the
outcome of another.
7. In an alternating treatments design, the extent of any differential effects
produced by two treatments is determined by the __________________
distance between their respective data paths and quantified by the
__________________ axis scale.
A. Horizontal, vertical
B. Vertical, horizontal
C. Vertical, vertical ✅
D. Horizontal, horizontal
Rationale: Data are typically displayed over time (x-axis), and treatment
effect is shown by changes in level (y-axis/vertical).
8. __________________ effects are the effects on a subject's behavior in a
given condition that are the result of the subject's experience with a prior
condition.
A. Learning
B. Confounding
C. Sequence ✅
D. Maintenance
Rationale: Sequence effects result from the order in which conditions are
presented.
, 9. Which of the following statements is a practical rationale for using B-A-B
reversal design?
A. It’s simpler than A-B-A designs
B. The behavior is dangerous, and treatment is already in place ✅
C. To test multiple interventions
D. Baseline is unnecessary
Rationale: B-A-B designs are ethically used when removing treatment could
be harmful.
10. When it is not possible or appropriate to completely eliminate the event or
activity used as a contingent reinforcer this variation of the reversal design
can be employed.
A. Withdrawal
B. NCR reversal ✅
C. Multiple baseline
D. A-B-A-B
Rationale: Noncontingent reinforcement (NCR) reversal allows the reinforcer
to remain present noncontingently.
11. Behavioral ____________ means that the level of behavior observed in an
earlier phase cannot be reproduced even though experimental conditions
are the same as they were during earlier phases.
A. Replication
B. Generalization
C. Irreversibility ✅
D. Maintenance
