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

• A. Inter-response time (IRT)
• B. Latency
• C. Discrete categorization
• D. Percent duration

Answer: (B)

Latency is the interval from when the stimulus appears to the moment the first movement or response begins. It measures how quickly someone perceives and initiates a response, focusing on the start of the action rather than its execution. In contrast, inter-response time looks at the gap between successive responses, discrete categorization refers to classifying stimuli into categories, and percent duration isn’t the standard term for this timing aspect. So latency best describes the time from stimulus onset to initiation of the response.
