Important characteristics of Long Delay Conditioning:
Consider the unconditioned reflex whereby food elicits (US) elicits salivation (UR). In Long Delay Conditioning, a tone (NS) might sound for several seconds before the food (US) is presented. Consequently, the tone (CS) may come to elicit salivation (CR) even in the absence of food. With repeated conditioning trials, salivation may become increasingly delayed to when tone first sounds, occurring progressively closer in the time to food delivery. In addition, the eliciting effect of the tone may be less pronounced the longer its typical duration prior to food delivery.
