RESTRICTED GENERALIZATION, BIAS, AND LOSS OF POWER THAT MAY RESULT FROM MATCHING GROUPS.
BEEMAN, ELLEN Y.; STANLEY, JULIAN C.
THIS STUDY CRITICALLY EVALUATED MAJOR PUBLISHED STUDIES DEALING WITH PSYCHOLOGICAL AND EDUCATIONAL ASPECTS OF MENTAL RETARDATION AND PREPARED AN EXTENSIVE, DETAILED ANALYSIS OF RESEARCH METHODOLOGY ON THIS SUBJECT. THIS WAS A LIBRARY RESEARCH PROJECT IN WHICH A GREAT BODY OF LITERATURE WAS SURVEYED, ESPECIALLY PERIODICALS. SELECTED CLUSTERS OF STUDIES AND SINGLE STUDIES ILLUSTRATING THE METHODOLOGICAL POINTS WERE EMPHASIZED. A FEW RESEARCHERS IN MENTAL DEFICIENCY ARE PERFORMING THEORETICALLY ORIENTED EXPERIMENTS, UTILIZING MODERN PRINCIPLES OF EXPERIMENTAL DESIGN AND ANALYSIS. THE GREATEST PRESENT NEED SEEMS TO BE TO APPLY SUCH PRINCIPLES TO THE TESTING OF HYPOTHESES DERIVED FROM CONSIDERATION OF PRIOR EMPIRICAL FINDINGS. STATUS STUDIES, SUCH AS COMPARING "FAMILIALS" WITH BRAIN-INJURED AMENTS ON THE BENDER GESTALT, DO ADD TO KNOWLEDGE AND THEORY, OF COURSE, BUT IT APPEARS TO THE INVESTIGATORS THAT MANIPULATION OF VARIABLES WITHIN THE CONTROL OF THE EXPERIMENTER SHOULD BE MORE FRUITFUL, PARTICULARLY WHERE THESE VARIABLES DERIVE FROM PRINCIPLES OF PSYCHOLOGY, PSYCHIATRY, MEDICINE, SOCIOLOGY, ANTHROPOLOGY, EDUCATION, AND OTHER RELATED DISCIPLINES. STUDY OF THE FEEBLEMINDED BY SOCIAL SCIENTISTS SEEMS LIKELY TO REMAIN CLOSER TO SERVICE THAN RESEARCH. PROBABLY A MORE OVER-ARCHING FRAME OF REFERENCE IS DESIRABLE, WITH DIMENSIONS OF INVESTIGATION CUTTING ACROSS VARIOUS LEVELS OF MENTAL DEVELOPMENT. THE RESEARCH CONCLUDED THAT MUCH FUNDAMENTAL (PURE) RESEARCH IS NEEDED IN ORDER TO DEVELOP THEORIES AND PRINCIPLES FROM WHICH RECOMMENDATIONS FOR PRACTICE CAN BE DEDUCED AND EVALUATED. (GC)
