The lever-pressing response of four dogs was reinforced with food on a 2-minute fixed-interval schedule, with salivation also being recorded continuously. Respondent salivary conditioning was found to occur during operant leverpressing conditioning, the occurrences of the two conditioned responses being positively correlated.
