Question 1

Which type of graph is most commonly used in single-subject ABA research to display data across conditions and phases?

Accepted Answer

Line graph

Answer

Line graphs display data points connected by lines across time, making it easy to visualize trends, level changes, and variability across experimental conditions.

Question 2

What does a 'phase change line' on a behavior graph indicate?

Accepted Answer

A change in the experimental condition or intervention

Answer

A phase change line is a vertical line drawn on a graph to indicate the point at which an experimental condition or intervention changed.

Question 3

What is the primary purpose of a cumulative record in behavior analysis?

Accepted Answer

To show response rate via slope across time

Answer

A cumulative record plots the total number of responses over time; the slope of the line directly reflects response rate, making rate changes visually apparent.

Question 4

Which measurement dimension is defined as the time elapsed between the onset of a stimulus and the initiation of a response?

Accepted Answer

Latency

Answer

Latency is the elapsed time between the onset of an antecedent stimulus and the start of the target response.

Question 5

Whole-interval recording tends to do which of the following relative to the true occurrence of a behavior?

Accepted Answer

Underestimate

Answer

Whole-interval recording underestimates behavior because it only scores an interval as positive if the behavior occurred throughout the entire interval.
