Latency

Latency measures the delay before a behaviour begins. In teaching, a short latency means a learner attends and responds quickly to an instruction. A long latency points to hesitation, processing delays, or avoidance.

You track latency when evaluating cooperation or fluency. You typically target it for reduction, like teaching a student to follow instructions faster. Sometimes you target it for increase, like teaching a learner to pause before impulsively grabbing an item.
