Abstract : The logic of and a circuit for differentiating an avoidance response from an escape response are described. In avoidance conditioning experiments two procedures are commonly used to distinguis between avoidance and escape responses. However, under certain conditions these procedures are unreliable when electrical shock is used as the unconditioned stimulus. An electronic gate was developed which, in combination with an electronic timer, times the duration of shock w ich an animal actually receives. By noting the prescence or absence of shock, it is possible to differentiate an escape response from an avoidance response. Techniques to distinguish accurately an escape response from an avoidance response by an electronic gate and timer are presented. (Author)
