Smeets, ter Laak, Jansen, & Hakker (1980) assessed the behavioral strategies of severely and profoundly retarded adults with four sets of tasks. In this study, the strategies are reconsidered based on three analyses of the individual tasks. The analyses produced the same results and prompted a redefinition of Strategy 2 and a more limited description of Strategy 3. In addition, the strategies are renamed as levels to emphasize their description of ascending levels of competence and behavioral complexity rather than of the stimulus condition. The relevance of these levels for the diagnosis and training of the profoundly and severely retarded is discussed.
斯米茨、特拉阿克、扬森和哈克（1980年）用四组任务评估了重度和极重度智障成年人的行为策略。在本研究中，基于对各项任务的三项分析重新审视了这些策略。分析得出了相同的结果，并促使对策略2进行重新定义，对策略3进行更有限的描述。此外，将这些策略重新命名为水平，以强调它们描述的是能力和行为复杂性的逐步提升水平，而非刺激条件。讨论了这些水平对极重度和重度智障者诊断与训练的相关性。
