Latency is a measurable dimension of behavior describing the time from the onset of the antecedent to the start of the response.

• A. Latency
• B. Interresponse Time
• C. Magnitude
• D. Frequency

Answer: (A)

Latency measures the time from the onset of the antecedent to the start of the response, capturing how quickly a behavior begins after a cue. This speed of initiation is what distinguishes latency from other behavioral dimensions. Interresponse time is the interval between successive responses, not the delay before the first response. Magnitude refers to the size or intensity of the response, and frequency (or rate) counts how often the behavior occurs over a period. For example, when an instruction is delivered and the learner starts the behavior after 0.8 seconds, that 0.8-second delay is latency.
