Which term describes the time between the onset of a stimulus and the initiation of a response?

The term that describes the time between the onset of a stimulus and the initiation of a response is latency. Latency is crucial in behavior analysis as it provides insight into how quickly an individual can respond to a given stimulus. A shorter latency can indicate that the individual is readily engaging with the task, while longer latency may suggest hesitation or difficulty in response.

Duration refers to the total time that a behavior occurs, which is distinctly different from the response time after a stimulus. Frequency measures how often a behavior occurs within a specific timeframe and does not pertain to the response time after a stimulus. Interresponse Time refers to the duration between successive occurrences of a behavior, which is also separate from the initial response time to a stimulus.
