    Abstract:
    In experiments with ablation of the forebrain dorsal cortex in turtles it has been established that this structure plays a significant role in first solving of an extrapolation task (6-19 times) and looses its integrating role at multiple test solving (40-195 times). The obtained data testify to the presence of two types of animals adaptive behaviour in solving the extrapolation task: based on operation with empirical laws of movement and manifested at first task presentations (elementary rational animals activity), and that based on learning and appearing after multiple reiterations of the experimental situation in the form of motor conditioned reflex of passing the obstacle from the corresponding side.
