Abstract
We examined immunization against learned helplessness in 36 dogs. The experiment consisted of five phases: (1) appetitive contingent training, (2) immunization training, (3) inescapable noise training, (4) recovery, and (5) an appetitive noncontingent test. There were six groups: (1) a group immunized by controllable and predictable noise, (2) a group immunized by controllable but unpredictable noise, (3) a group immunized by uncontrollable but predictable noise, (4) a group given uncontrollable and unpredictable noise during immunization training, (5) a group not submitted to any treatment during the immunization phase, followed by uncontrollable noise, and (6) a group not submitted to any treatment. The immunization effect was assessed by measuring the acquisition of an appetitive response when food was not contingent upon responding. Our results demonstrate that the immunization effect can be observed in a noncontingent appetitive context. The effects of escapable noises that ensure immunization against the motivational deficit and predictable noises that immunize against the associative deficit seem to be additive.
