Which term refers to the time between two successive responses?

Inter-response time refers specifically to the interval between two successive responses. This measurement is important in behavior analysis as it helps to understand the frequency and timing of behaviors displayed by an individual. By analyzing inter-response times, practitioners can gain insights into the patterns of behavior, determining whether the responses are occurring in quick succession or with a longer delay. This information can be crucial for adjusting interventions and understanding the dynamics of the behavior being studied.

The other terms listed, while related to time and behavior measurement, have different meanings and are used in different contexts. For instance, response time usually refers to the time taken for a response to occur after a stimulus is presented, which is distinct from the time between responses. Elapsed time typically refers to the total time taken for an event or behavior to occur, starting from the beginning of the observation period. Duration is often used to describe how long a single instance of behavior lasts rather than the interval between separate instances. Thus, inter-response time is the most accurate term for describing the time between successive responses.
