discrepancy between the number of formed skills and abilities and average age norms. A limited scope of skills and abilities can be observed with the biological or social impossibility to form a skill or ability (there is nothing to perform an action with or no one to show, teach an action) or with insufficient training in their consolidation and automation. The latter is often observed in the case of overprotection of the child, as well as in the volitional insufficiency of the individual himself with a quick refusal of the necessary “polishing” of activity.
