The effect of Person on cardiac and motor responsivity to shock in dogs
- 28 Downloads
Interaction between effect of social stimulus (Person) and a faradic shock on heart rate and motor response (leg flexion) in four dogs was observed and recorded. The trials during which the shock and petting were presented simultaneously showed a significant suppression of heart rate increase to shock when compared to the shock alone trials. The lack of this suppression effect in the motor response to the shock is discussed in relation to the concept of schizokinesis. The importance of controlling prior experience of subjects is also discussed.
