“…After that, each EFE was displayed concurrent with a Corsi Blocks trial. processing, the interference in our study may have been particularly strong [33,34] since two visuo-spatial tasks were used. This may have led to cognitive overload in these patients that was reflected in a poorer performance.…”

“…Indeed, it has been suggested that all types of facial recognition, with or without emotional content, are dependent upon visuo-spatial resources [28][29][30][31][32]. Like frontal lobe tasks, PD patients were found to have visuo-perceptual disorders and difficulties in visual tracking tests have been confirmed in PD patients [33,34], some of which may be attributed to deficits in visuo-spatial memory [35][36][37]. Significantly, abnormalities in facial perception have been cited as one of the sequelae of PD [38], suggesting that the underlying problem is a visuo-spatial dysfunction [39].…”

“…On the basis of previous studies, right hand superiority had been expected, especially since the test procedure seemed to favor the right hand, allowing right hand first untimed practice and then timing DIFFERENCE I \ in order of right-left-left-right. The most consistently significant right superiority has been reported in tasks requiring repetitive movements of fingers, hands or arms (Wyke 1967(Wyke , 1969Spreen and Gaddes 1969;Bowen et at. 1972).…”

“…Untimed practice (invariably done with the right hand) and invariable right-leftleft-right order of trials admittedly appeared to confer a certain practice advantage on the right hand, but the purpose of this normative study was simply to provide a standardized procedure of measurement and not to question right hand superiority (the question arose a posteriori: see results and discussion). This order has also been used in other studies of finger oscillation or tapping (Bowen et al 1972).…”

SUMMARY The rapidity of finger movements was tested in a group of 237 normal, right‐handed children aged between 5 and 8 years. The children were required to do 20 ‘tapping’ movements repetitively (index finger against thumb) and successively (each finger in turn against thumb) with each hand. Both types of movement were performed more rapidly with increasing age and repetitive movements were performed faster with the right hand. However, while the percentage of children performing repetitive taps faster with the right hand increased with age, the magnitude of right‐hand superiority decreased with age. Successive movements with both right and left hands were performed more rapidly by girls. These findings are compared with other reports of right vs left superiority in hearing and motor task performance and of other sex differences in cerebral maturation. RÉSUMÉ La rapidité des mouvements digitaux a été testée dans un groupe de 237 enfants normaux, droitiers âgés de 5 à 8 ans. On a demandé aux enfants de réaliser des mouvements de ‘frappe’ répétitifs (index contre pouce) et successifs (chaque doigt à son tour contre le pouce) pour chaque main. Les deux types de mouvements sont réalisés à des vitesses accrues lorsque l'âge augmente et les mouvements répétitifs sont réalisés plus rapidement avec la main droite. Cependant, quoique le pourcentage des enfants réalisant la frappe plus rapidement avec la main droite augmente avec l'âge, l'amplitude de la supériorité de la main droite décroit avec l'âge. Les mouvements successifs aussi bien avec la main droite qu'avec la main gauche sont réalisés plus rapidement par les filles. Ces découvertes sont comparées à d'autres travaux sur la supériorité droite‐gauche dans l'audition et la réalisation de tâches motorices ainsi qu'avec d'autres différences liées au sexe dans la maturation cérébrale. ZUSAMMENFASSUNG Bei einer Gruppe von 237 normalen, rechtshändigen Kindern im Alter zwischen fünf und acht Jahren wurde die Geschwindigkeit von Fingerbewegungen untersucht. Die Kinder mußten mit jeder Hand wiederholt den Zeigefinger gegen den Daumen und nacheinander jeden Finger gegen den Daumen tippen. Beide Bewegungsarten wurden mit zunehmendem Alter schneller ausgeführt, die repetitiven Bewegungen schneller mit der rechten Hand. Obwohl der Prozentstaz der Kinder, die die repetitiven Bewegungen besser mit der rechten Hand ausführten, zunahm, verminderte sich mit zunehmenden Alter das Überwiegen der Rechtshändigkeit. Die sukzessiven Bewegungen wurden von Mädchen mit beiden Händen schneller ausgeführt. Diese Befunde werden mit anderen Berichten über Rechts‐gegenüber Links‐Dominanz bei der Ausführung akustisch erteilter Aufgaben und anderer Geschlechtsunterschiede in der Hirnreifung verglichen. RESUMEN Se examinó la rapidez de movimientos digitales en un grupo de 237 niños normales dextrómanos de 5 a 8 años de edad. Se pidió a los niños que realizaran movimientos de golpeteo repetitivos (indice contra pulgar) y movimientos sucesivos (cada dedo sucesivamente contra al pulgar). Ambos tipos ...

“…Bowen et al [3] measured the performance of patients with Parkin son's disease in two motor tasks -repetitive tapping of a button and tracking a light moving at random on a screen. They reported that pa tients with primarily right-sided symptoms (left hemispheric dysfunction) had bimanual alteration in both the tapping and the tracking tasks, whereas patients with primarily left-sided symptoms (right hemispheric dysfunction) performed significantly worse than the controls on the tap ping test only with the hand contralateral to the major brain damage.…”

Postural dependence of the EMG-RT of the triceps brachii muscles was measured in 68 parkinsonian patients of which 38 underwent a ventrolateral thalamotomy. A thalamotomy did not affect patients’ EMG-RT per se, but it changed the postural dependence of the EMG-RT. After left thalamotomy the position changes of both shoulders did not influence the EMG-RT of the right triceps, and after right thalamotomy the position change of the left shoulder had no influence on the EMG-RT of both triceps. As for the sensorimotor function, it is assumed that the right thalamus has bilateral control on the input system and the left thalamus has bilateral control on the output system.
