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.
四只狗的压杆反应按照2分钟固定间隔时间表用食物进行强化,同时唾液分泌也被持续记录。发现在操作性压杆条件反射过程中会出现反应性唾液条件反射,两种条件反应的出现呈正相关。
