Activation of change processes in cognitive capacity of 71 institutionalized adults with mental retardation in four age groups was investigated. The central means of intervention was the Instrumental Enrichment Program. Effects of the intervention were examined in reference to logical thinking, predictive thinking, and insightful thinking. The test series was administered twice before and twice after the intervention. Although all subjects improved significantly, the initial and final scores of adults with Down syndrome were lower than those of adults with other forms of mental retardation. Subjects with moderate retardation achieved greater improvement than did those with mild retardation only in the Children Test. Significant changes were obtained in all age groups. For logical and predictive thinking, a divergency effect was found. Results support structural cognitive modifiability theory.
研究了针对四个年龄组的71名机构收容的智力迟钝成年人认知能力变化过程的激活情况。干预的主要手段是工具性充实计划。参照逻辑思维、预测性思维和洞察力思维对干预效果进行了检验。在干预前后分别进行了两次测试。尽管所有受试者都有显著改善，但唐氏综合征成年人的初始和最终得分低于其他形式智力迟钝的成年人。中度智力迟钝的受试者仅在儿童测试中比轻度智力迟钝的受试者取得了更大的进步。所有年龄组均有显著变化。对于逻辑思维和预测性思维，发现了一种差异效应。结果支持结构认知可改变性理论。
