A review of the literature on aversive Pavlovian (classical) conditioning was conducted to determine whether various conditioned responses (CRs) develop at the same or at different rates. Statistical analyses revealed a bimodal distribution of the rates of acquisition of various types of CRs. Rapid acquisition (M = 5.7 trials to first consistent CR) occurs for conditioned suppression and changes in galvanic skin response, blood pressure, respiration, pupil size, and heart rate. Slower… CONTINUE READING
