Hyperactivity in a Group of Epileptic (and some Non‐Epileptic) Brain‐Damaged Children A Behavioural Study, with Some Implications for Education

摘要: SUMMARY The behaviour of 16 brain-damaged children was studied in a “free field”, an environment which the child free to behave as he wished, but whose physical limits were fixed. Half had been diagnosed showing classical hyperkinetic syndrome. The aim study examine way two groups explored made systematically more complex. Their compared with that group normal similar age. environments ranged from empty room social situation. The exploratory behaviours observed visual fixations, locomotion, and manipulation environment. It found measures “sampling time”, i.e. mean duration manipulatory activities, time spent continuously contact stimulus, significantly shorter than non-hyperkinetic group, both normals. Whereas showed variability sampling appropriate environmental changes, children, particularly hyperkinetics, very little change became In terms total amount allocated various activities range stimuli engaged, differed markedly degree behavioural modifiability approaching normals. The relationship between eventually upon stimulus can be understood particular “strategy” employed by exploring its environment.

RESUME Le comportement de enfants presentant une atteinte organique du cerveau eteetudie en “champ libre”, c'est dire environnement dans lequel ces etaient libres se comporter comme ils le desiraient, mais dont on fixait les limites physiques. La moitie seulement presentait un syndrome classique d'hyperkinesie. Le l‘etude etait d'examiner la maniere 2 groupes exploraient systematiquement rendu plus complexe. On compara leur avec celui d'un groupe d'enfants normaux meme âge. Les environnements sont classables depuis chambre vide jusqu’a situation sociale. Les comportements d'exploration observes concernent fixations visuelles, locomotion et l'environnement. trouve que mesures “des sequences temporelles l'activite”, duree moyenne des activites visuelles manipulations, temps maintien significativement courts hyperkinetiques non-hyperkinetiques, et, d'autre part, chez normaux. Alors montraient variabilite“des d'activite” appropriee aux changements, atteintes organiques particulier, hyperkinetiques, tres peu changement d'activite quand l'environnement devenait complexe. Si l'on exprime resultats par passea variees nombre choix effectues, non-hyperkinetiques different nettement presented degre plasticite proche normale. La entre l'activite eventuellement passe sur peut etre envisagee termes “strategic” caracteristique employee enfant l'exploration son environnement. On etudie rapport Broadbent longues courtes systemes nerveux. suggere nombreux ayant subi cerveau, ont pour caracteristiques recevoir l'information courtes. Enfin ceci l'education discutees.
