Abstract

Three groups, each with 15 seriously retarded institutionalized children, were employed to evaluate a modification of the sensorimotor patterning treatment developed at the Institutes for the Achievement of Human Potential (IAHP). The treatment group received a program modeled after the IAHP methods for approximately two hours per day, five days per week, for one year. For the same length of time, a matched motivational control group participated in activities with foster grandparents designed to create positive, success-oriented interactions to improve self-esteem and feelings of efficacy. A no treatment group continued to receive the standard care of the institution, which was enlightened and resident-oriented. A wide variety of behavioral measures were employed, including the IAHP Developmental Profile, IQ, motor and language development scales, and measures of affective, social, and maladaptive behaviors. On the majority of the measures there were no differences in posttest performance among any of the three groups. In no case did the pattern of change of the treatment group differ from that of its crucial comparison, the motivation group. However, all three groups showed some improvement in performance between the beginning and end of the study. It was concluded that the patterning treatment investigated in this study cannot be recommended for seriously retarded children.
