Study of the problem of choice and decision-making becomes increasingly relevant area of psycho - and neurophysiology [2]. Closest to the ethological observations selection processes and decision making in animal experimental models are model of spontaneous learning using techniques of free choice. E.Thorndike was the first to use this method, when the animal all the information on the task appears in the first experience of self-study and formation of behavior [3]. Previously, we have shown the formation of the 2-specific sequence time-patterns of selection by rats of the eating and drinking reinforcements [1]. The purpose of this study was to identify individual-typological peculiarities of formation of such patterns, their sustainability after the break. Experiments were conducted on 37 male rats Wistar. It uses a complex «Rat Touch Screen Chamber» (Lafayette Instrument, USA). After a food and drink deprivation, the rats were placed in a box where they are through self-study area, nose or paw touched on the screen to one of the images. If the rat touches to the first stimulus it is supplying a one food pellets. If the rat touched to the second stimulus it is supplying of the water portion. It is shown that in the process of spontaneous learning to combined feeding and drinking behavior of rats in an interactive environment in 50% of rats successfully elaborated skill training for 4-7 sessions. After a 42-day break, they quickly (within 1-2 sessions) were on previously developed level of skill. Group 2 rats (30%) studied produces a skill to the 12th session of training, subsequently achieved high indicators in Group 1. In 20% of the rats on these terms do not develop the skills of self-clicking on the image of the conditioned signal to obtain reinforcements. Later, however, these rats still learned to 15-18m training sessions. The number of feeding acts significantly exceeded the number of drinking and constituted 60-80% of the total number of tools of behavioral acts. After the break, typical for the rat type of the time pattern of alternations choice of drink and food remained. Thus, we have shown that rats successfully on their own (spontaneously) are trained using the interactive screen to select the reinforcements.
