 The term is latency. It is defined as the time from the discriminative stimulus until the response occurs. Latency. Also referred to as response latency. The longer the latency, the longer it takes from the time that a prompt occurs, or a discriminative stimulus, to the behavior happens. The shorter the latency, the quicker it occurs. The quicker the behavior occurs in the presence of the discriminative stimulus. So as soon as the discriminative stimulus turns off, you have a response. That would be response latency has decreased dramatically between words. If I increase my response latency between words, you would probably not listen to my definitions. Thank you.
