“…In early childhood, mean ratio IQs declined from 73 at 6 weeks to 44 at 4 years old (Carr 1975), similar to the findings of other research (Dameron 1963; Shipe & Shotwell 1965; Dicks‐Mireaux 1972), and at 11 years to 40, due perhaps to the preponderance of verbal items in the Merrill‐Palmer, the test used at 11 years. Thenceforward, the Leiter Scale was used, and average non‐verbal IQs are shown in Table 2, for the whole group, for men and for women.…”

“…Between the 1960s and 1980s a number of longitudinal studies were undertaken designed to map the intellectual development of children with Down Syndrome (Dameron 1963; Shipe & Shotwell 1965; Dicks‐Mireaux 1972; Melyn & White 1973; Berry et al. 1984).…”

“…Three studies indicate that the IQ scores of Down syndrome infants decline over the first two years of life. Testing 12 children admitted to a state hospital between the ages of 2 and 5 months with the California First Year Mental Scale at 3 month intervals, Dameron (1963) charted a consistent decline in IQfrom an average score of 94 at 3 months to 46 at 18 months. In a second study, Dicks-Mireaux (1972) administered the Gesell Developmental Scales to 20 nonretarded infants and 21 infants with Down syndrome five times between the ages of 16 weeks and 30 months.…”

Many researchers of mental retardation fail to take etiological differences into account, although the value of distinguishing between organic and familial mental retardation has long been discussed. The argument is made that even the two-group approach needs to be extended so that groups with different organic etiologies are studied separately. Taking etiological distinctions into account will allow for more precise research and a better understanding of mental retardation. Evidence for the utility of differentiating retarded persons by etiology is provided by a research review showing examples of behavioral differences between organically retarded groups. It is concluded that such differentiation also has clear implications for intervention.

“…The Bayley,mental and motor scales were used for each infant. Although the Bayley Scales were standardized on a sample of normal children, they have been used repeatedly t o assess Down's syndrome infants (Dameron 1963, Carr 1970, LaVeck and LaVeck 1977 and have been specifically recommended as the instrument of choice for research with such infants (Eipper and Azen 1978). They were particularly appropriate for this study because they provide both mental and motor scores.…”

SUMMARY A group of 20 infants with Down's syndrome, aged between two months and 21 months, was tested initially on the Bayley Scales of Infant Development and the Peabody Developmental Motor Scales. Four treatment objectives were developed for each individual infant, and they were then randomly assigned to an experimental or control group. The experimental group were given an individual neurodevelopmental therapy program three times a week in their own homes for a period of nine weeks. When the infants were post‐tested on the Bayley and Peabody Scales, no significant difference was found between the two groups. However, there was a statistically significant difference in favour of the experimental group in attainment of individual treatment objectives. RÉSUMÉ Les effects d'une thérapeutique neurodevelopmentale dans l'amelioration des performances motrices chez des nourrissons mongoliens 20 nourrissons mongoliens âgés de deux à 21 mois ont été testés initialement avec les échelles de développement de Bayley et les échelles de développment moteur de Peabody. Quatre objectifs thérapeutiques ont été décidés pour chaque nourrisson et ceux‐ci ont été ensuite assignés au hasard dans un groupe experimental et un groupe controle. Le groupe experimental reçut un programme de therapeutique neurodevelopmental individuel, à domicile, trois fois par semaine, durant une période de neuf semaines. Lorsque les nourrissons furent testés à nouveau, sur les échelles de Bayley et de Peabody, il ne fut trouvé aucune différence significative entre les deux groupes. Cependant une difference statistiquement significative en faveur de groupe experimental fut notée dans la réalisation des objectifs thérapeutiques individuels. ZUSAMMENFASSUNG Erfolge einer neurophysiologischen Therapie zur Verbesserung der Motorik bet Kindern mil Down Syndrom Eine Gruppe von 20 Kindern mit Down Syndrom im Alter zwischen zwei und 21 Monaten wurde zu Beginn der Studie nach den Bayley Scales für die Kindliche Entwicklung und den Peabody Developmental Motor Scales getestet. Für jedes einzelne Kind wurden vier Behandlungsziele festgesetzt und die Kinder wurden dann willkiirlich einer Behandlungsgruppe oder einer Kontrollgruppe zugeordnet. Die Kinder der Behandlungsgruppe wurden tiber einen Zeitraum von neun Wochen dreimal wochentlich zu Hause nach einem individuell abgestimmten neurophysiologischen Behandlungsplan behandelt. Als die Kinder erneut nach den Bayley und Peabody Scales getestet wurden, fand sich kein signifikanter Unterschied zwischen den beiden Gruppen. Es fand sich jedoch ein statistisch signifikanter Unterschied zu Gunsten der Behandlungsgruppe hinsichtlich des Erreichens der individuellen Behandlungsziele.
