Abstract
Assessed the effects of terminal food and water deprivation on operant responding reinforced by light onset or offset in 64 naive albino rats. Results indicated that: (1) light onset had relatively weak reward value for satiated Ss; (2) light onset was a stronger reinforcer than light offset; and (3) deprivation enhanced the rewarding properties of both kinds of illumination change. Results support the hypothesis that hunger and thirst increase rats' tendencies to respond, producing changes in stimulation. (16 ref.)
