What is the term used to describe the elapsed time between two successive responses?

The term that describes the elapsed time between two successive responses is interresponse time. This concept is crucial in behavioral analysis because it helps practitioners understand the temporal aspects of behavior, particularly how quickly an individual responds after completing one behavior before they start another.

Measuring interresponse time can provide valuable insights into an individual's response patterns, helping to identify any delays or rapid sequences of behavior, which can be significant for developing effective intervention strategies.

In contrast, latency refers to the time that passes between the presentation of a stimulus and the individual's response to that stimulus. Duration measures the amount of time that a behavior occurs, while frequency counts how often a particular behavior occurs within a specified period. Thus, these terms serve distinct purposes in behavior analysis, but interresponse time specifically focuses on the interval between consecutive responses, making it the correct term for this question.
