Which measure represents the amount of time between an antecedent stimulus and the response?

• A. Percent duration
• B. Latency
• C. Inter-response time (IRT)
• D. Partial interval recording (PIR)

Answer: (B)

Latency is the time from the onset of a stimulus to the initiation of the response. It captures how quickly someone starts to respond after being prompted. For example, if a light comes on and a person begins pressing a button 0.6 seconds later, that 0.6-second interval is the latency. This is different from inter-response time, which is the interval between successive responses, not tied to a preceding cue. Percent duration measures how long the behavior lasts during the observation period, not how quickly it starts. Partial interval recording is a data collection method that notes whether the behavior occurs at any time during each interval, not the precise time of the first response. So the described measure is latency.
