On the syndrome of psychomotor instability.
This syndrome is most commonly met with in brain-injured children. It shows several aspects of psychopathological features. The most impressive is restlessness along with the poor coordination of movements. Signs of psychic infantilism can be seen in the form of uncontrolled emotional outbursts of the child under frustration and as a lack of persistence in striving towards a goal. Another typical feature is their impulsiveness. There is a further attempt made to give a more detailed analysis of this concept. The work of Freud, Levin, Luria, Eysenck and Cohen relative to this topic is briefly mentioned. An account on some results of research at Psychiatric Clinic in Prague follows. By means of systematic observation and questionnaires children in nursery schools were grouped into impulsives, social extraverts and introverts. Some differences in performance were predicted in reaction time, learning and relearning of a central set etc. Analysis of variance between the aforesaid groups has revealed some significant differences.
