a) presenting the bell to produce saliva; repeatedly presenting the sound of the bell followed by food; identifying the bell as a neutral stimulus; identifying food as the unconditioned stimulus.
b) identifying the bell as a neutral stimulus; repeatedly presenting the sound of the bell followed by food; presenting the bell to produce saliva; identifying food as the unconditioned stimulus.
c) identifying the bell as a neutral stimulus; identifying food as the unconditioned stimulus; repeatedly presenting the sound of the bell followed by food; presenting the sound of the bell to produce saliva.
d) presenting the bell to produce saliva; identifying the bell as a neutral stimulus; repeatedly presenting the sound of the bell followed by food; identifying food as the unconditioned stimulus.
