Terminology; learning difficulties or mental retardation

Mental retardation, mental age, and learning rate.

Zigler's hypothesis that mental age (MA) and not IQ determines the rate of learning is examined in the light of empirical evidence comparing the learning rates of normal and retarded children and young adults matched for MA. The results show that learning rate is a function of IQ as well as of MA. In general, children of average IQ learned serial and paired-associate lists significantly faster ...

Towards A More Acceptable Terminology in Mental Retardation

ORE than a year has elapsed since the publication of the long awaited and sorely needed terminology and classification manual, made possible through the joint sponsorship of the United States Department of Health, Education and Welfare and the American Association on Mental Deficiency (Heber, 1959). Despite the considerable significance this manual will have in aiding the establishment of a com...

In the preface, it is said to be aimed at an intelligent lay audience and it is suggested that 'it will be read with interest and profit by workers in the field of m...

Yet, this text discusses neither protein structure nor nucleic acid structure and minimizes discussions of drug induced conformational changes. In other words, this volume is a good textbook of nonmolecular pharmacology. In the introduction th...
