| Food cues (FCs) serve as conditioned and discriminative stimuli for eating and likely play a role in obesity. This study aimed to condition and extinguish FCs in twenty-four healthy-weight and twenty-three overweight/obese women and determine the extent to which FCs induced changes in behavioral economic aspects of food reinforcer efficacy, namely values of demand (elasticity and intensity) and delay discounting (DD) for food. Participants underwent respondent conditioning with neutral visual cues paired with chocolate. Conditioned swallowing response(CR+), demand elasticity and intensity for food, and food DD were measured across threeconditions: baseline, post-acquisition, and post-extinction. Results show FCs increased CR+ and demand intensity and decreased demand elasticity. Changes in CR+, elasticity, and intensity did not extinguish post-extinction. DD did not change across conditions. Finally, no group differences were observed across any of dependent variables. Conditioned FCs, then, not only increase conditioned salivation, but also alter demand for food.
