| Research Abstract |
To investigate the interaction between the classical conditioning and the operant conditioning, behavior of goldfish in aversive conditioning situations was analysed. The position of subjects was recorded by means of picture-analysis equipment and personal computer, and amount of movement and speed in various periods of the conditioning trials were calculated.
In Experiment I, condition was shifted from classical to avoidance or vice versa. The result showed that in classical conditioning goldfish move faster on trials where they made response than on trials where they did not. There was no such difference in avoidance conditioning. Another difference was showed in the period after response. In avoidance subjects did not move so much after getting into the another compartment of the shuttle box, but in classical conditioning the amount of movement was rather high. It may reflect the expectancy of the electric shocks.
In Experiment II, the effects of shift from avoidance to punishment was examined. Response was maintained after the shift, if shock was given and conditioned stimulus was terminated immediately after the response. The speed of moving into the adjoining compartment was higher after the shift. the behavior seems to be a kind of self-punitive behavior. Response was suppressed, if conditioned stimulus continued after response to the predetermined point of time and shock was given simultaneously with the termination of conditioned stimulus. This paradoxical phenomena should be explained future.
In Experiment III, yoked control subjects were used to get more information about the difference between classical and poerant conditioning. but unambiguous data could not be obtained.
