[Behavior of dogs in a situation of simplified conditioned choice]

Dynamics of elaboration and stabilization of conditioned motor alimentary reactions was studied in dogs, in conditions of choice of one of two feeders. The whole process is divided into four stages, differing by the degree of stabilization of conditioned behaviour. Three groups of animals are singled out, characterized by different rate and features of elaboration of conditioned motor reactions. The possibility is shown of the use of total choice and running time as a characteristic of equilibration of nervous processes in animals.
