| Popis: | Three groups of goldfish (2 normal and 1 telencephalon ablated) were trained to avoid electric shock by crossing a barrier in a twoway shuttle box whenever a tone sounded. Then, while isolated in a distinct compartment, one normal and the ablated group received discriminative classical defense conditioning with two visual cues (CS+, CS−), while the other normal group received pseudoconditioning. Lastly, in the shuttle box, all fish had unreinforced test presentations of the visual CSs intermixed with avoidance retraining trials to the tone. The classical conditioned normal and ablated groups did not differ and both showed immediate, discriminative transfer of control of avoidance responding to the CS+ as they did to the tone, while for the pseudoconditioned normal fish the CSs did not control avoidance behavior. These results suggest that the telencephalon does not play a significant role in the integration and utilization of conditioned fear reactions with previously learned avoidance responses to generate appropriate behavior. |
