ABA Research, Analysis, and Intervention 5

Question 1

A behavior analyst calculates the percentage of non-overlapping data (PND) between baseline and treatment phases and obtains a value of 30%. This suggests the intervention is:

Accepted Answer

Questionable or ineffective, warranting reconsideration of the intervention

Answer

PND below 50% is generally interpreted as indicating an ineffective intervention; 30% indicates most treatment data overlap with baseline, suggesting minimal impact.

Question 2

When planning a function-based intervention, identifying the 'setting event' is important because setting events:

Accepted Answer

Alter the value of reinforcers and punishers, affecting the probability of behavior occurring

Answer

Setting events (establishing operations that occur distantly in time or context) alter the momentary value of reinforcers and punishers, thereby changing response probability.

Question 3

A BCBA conducting systematic direct observation uses momentary time sampling (MTS). Compared to whole-interval recording, MTS is considered more appropriate for behaviors that are:

Accepted Answer

Moderate to long in duration, such as on-task behavior or engagement

Answer

MTS yields estimates closest to true duration for behaviors that last long enough to be captured at the end of each interval, such as sustained engagement.

Question 4

In applied behavior analysis, 'technological' as a characteristic of behavioral intervention means:

Accepted Answer

The procedures are described with enough detail that a trained reader can replicate them

Answer

Baer, Wolf, and Risley (1968) defined 'technological' as requiring procedures described precisely enough for any skilled reader to replicate them exactly.

Question 5

A researcher evaluates treatment outcomes using both statistical significance and effect size. The effect size measure most commonly reported in single-case ABA research is:

Accepted Answer

Tau-U (or Tau-nonoverlap)

Answer

Tau-U (a non-overlap effect size that accounts for trend in baseline) is widely recommended and reported in single-case ABA research.
