[Various analogues of the second-signal behavior in monkeys during their symbolic "description" of properties of planimetric figures].
An attempt was made of experimental simulation of some components of the "second-signal" (verbal) behavior in rhesus monkeys (Macaca mulatta) under conditions of their "dialog" with a computer. Three monkeys were trained to perform manipulative actions on keyboard simulator to "describe" the properties of planimetric figures. For the period of research, the monkeys have learned to reproduce combinations of two symbols ("bigrams") that were used by them for a "description" up to 12 geometrical figures of various sizes. The data obtained indicate that rhesus monkeys are able not only to generalize the properties of a certain class of visual images at the perceptual level but also to use symbols for the description of these generalized properties.
