The document reports a study to determine if there is a higher incidence of behavior disorders or language differences in a group of 50 2-year-old Ss who have multiple minor physical anomalies as compared to a group with four or fewer anomalies, and to determine if there is a significant correlation between behavior disorders and language development delays or disorders. Chapter I contains sections which include information on the problem, purposes of the study, definition of terms, and limitations of the study. A literature review comprises Chapter II focusing on five major areas: need for early identification of at risk children, minor physical anomalies research, hyperactive behavior disorders, language development, and language disorders. A third chapter summarizes study methods and procedures, which include selection of the sample, instrumentation, and data analysis. Among findings reported in Chapter IV are that anomalies scores alone did not predict those 2-year-old children who evidenced behavior disorders or language differences and that a high anomaly score at 1 year combined with obstetrical complications significantly related to hyperactive behavior at 2 years. A final chapter discusses results and considers implications of the study. Appended materials include a list of anomalies and scoring weights, information on the Developmental Sentence Analysis, and sample recording forms. (SBH)
