LABORATORY ESTIMATING RATE OF ACTIVE-AVOI DANCE LEARNING OF FISHES INNATURAL-ENVIRONMENT - RESULTS OF GOLDFISH (CARASSIUS-AURATUS) TESTING

An experiment reproducing under standard laboratory conditions the pro cess of active avoidance learning similar to that in natural environme nt was set up. Before the beginning of a conventional active avoidance training in a shuttlebox (with visual conditioned stimulus-CS) pre-tr aining of fishes was conducted using the same apparatus according to t he same technique,but without CS presentation. After including CS into training, active avoidance developed fast and mighty. This process co rresponds to fast learning of the fishes observed in nature.
