Abstract
The effects of superimposing a 60-sec prefood stimulus on a multiple variable-interval extinction schedule of reinforcement were examined with a rat. Response rates in both components increased during the stimulus. There was no evidence of an impairment in discrimination performance, as has been reported with a similar procedure involving a preshock stimulus instead of a prefood stimulus.
