Separate groups underwent fear conditioning (tone-shock trials) with CS-UCS intervals favouring reinforcement (CR-UCS offset; Group 1), CS-UCR contiguity (Group 2), and contiguity and reinforcement (interval shifted during training; Group 3) while a control group (Group 4) had unpaired presentations of CS and UCS. Fear conditioning, extinction, and spontaneous recovery were measured through the probestimulus technique, with light as probe stimulus and pre-instructed hand lifting as probe response. Predictions derived from Jones' (1962) hypothesis were confirmed; Groups 2 and 3 were superior to Group 1 at first, while Group 3 was superior to Group 2 later in training. All experimental groups showed extinction, and Groups 1 and 3 showed spontaneous recovery in later retraining. The data were taken to confirm the main hypothesis that the fear response itself has a latency of the order of 2000-2500 msec. |
