Abstract:
We used previously refused foods as positive and negative reinforcement in the acquisition of cup drinking. Cup drinking increased with positive and negative reinforcement, both alone and in combination (without escape extinction), indicating that treatment of food refusal can establish some foods as appetitive stimuli whereas others remain aversive.
