Abstract

Rats with extensive variable-interval (VI) lever-press training for food were given unlimited access to food in home cages. In 70 VI sessions rats continued to respond and consume pellets although mean response rate dropped from 47 to 4 responses/min. Half the rats received extinction during the last 11 sessions, and their response rate dropped to 0.0 responses/min. Results may reflect effects of continuous illumination on eating behavior in rats.
