ABAT Data Collection and Analysis 5

Question 1

A therapist records how long a child engages in self-stimulatory behavior during each session. This is an example of:

Accepted Answer

Duration recording

Answer

Duration recording captures the total amount of time a behavior occurs, making it suitable for continuous behaviors like self-stimulation.

Question 2

Which visual analysis criterion refers to the average level of data points within a phase?

Accepted Answer

Level

Answer

Level refers to the mean or median value of data within a condition, reflecting the overall magnitude of responding.

Question 3

In a reversal (ABA) design, why is returning to baseline (the second A phase) important for data analysis?

Accepted Answer

It demonstrates experimental control by showing behavior reverts without the intervention

Answer

The second baseline phase demonstrates that behavior changes were caused by the intervention, not extraneous variables, establishing experimental control.

Question 4

A behavior analyst divides a 10-minute session into 30-second intervals and records whether the target behavior occurred at least once per interval. This is:

Accepted Answer

Partial-interval recording

Answer

Partial-interval recording scores an interval as positive if the behavior occurs at any point during the interval, regardless of duration or frequency.

Question 5

When comparing two phases in a graph, 'percentage of non-overlapping data' (PND) is used to:

Accepted Answer

Estimate the treatment effect size

Answer

PND quantifies treatment effectiveness by calculating the percentage of intervention data points that exceed the highest baseline data point.
