In the first study, subjects escaped shock by pressing on a lever under an unsignalled condition. By pressing a different lever they changed the condition to signalled escape for three minute periods. The second study used the changeover procedure to study inescapable‐unavoidable shock. Seven rats were used in each study. All subjects in both studies changed over from unsignalled to signalled conditions. Once contact with the signal condition was made, subjects responded to remain in that condition. The three different extinction conditions showed that the correlated stimulus without the signal had greater control over responding than the signal without the correlated stimulus. An analysis based upon shock and shock‐free periods was presented.
