Abstract:
The learning behaviour of earthworm was studied using labyrinth with differently difficult coefficients. Three different labyrinths were designed for the experiment. The earthworms were trained to recognize the correct aim of the labyrinth. The trainings were quitted soon after the subjects recognized the aims. 72 hrs later, the animals were tested again to see if they still remembered the correct arms. The results indicated that the memory maintenance time and the difficult coeffient of the labyrinth is in inverse ratio, namely, the higher the difficult coeffient of the labyrinth is, the more training time needs.
