Ability for self-regulation is assumed to be closely connected with development of speech. Some modifications in inter- and intrapsychological development of individuals with disturbed ability for speech communication are considered. An educational principle is underlined which states that interpsychological deficiences must be corrected by means of correction of interpersonal relations through activation of social functions within corresponding children's collectives. In order to improve capacity of a child for self-regulation the teacher must try to increase capacity for self-regulation of the collective in general.
