Sensitivity theory attempts to account for the variability often observed in challenging behavior by recourse to the "aberrant motivation" of people with intellectual and developmental disabilities. In this article, we suggest that a functional analysis based on environmental (challenging environments) and biological (challenging needs) motivating operations provides a more parsimonious and empirically grounded account of challenging behavior than that proposed by sensitivity theory. It is argued that the concept of the motivating operation provides a means of integrating diverse strands of research without the undue inference of mentalistic constructs. An integrated model of challenging behavior is proposed, one that remains compatible with the central tenets of functional analysis.
敏感性理论试图通过诉诸智力和发育障碍者的“异常动机”来解释在挑战性行为中经常观察到的变异性。在本文中，我们认为，基于环境（具有挑战性的环境）和生物学（具有挑战性的需求）动机性操作的功能分析，比敏感性理论所提出的解释更简洁且有实证依据。有人认为，动机性操作的概念提供了一种整合不同研究线索的方法，而无需过度推断心理主义结构。本文提出了一个挑战性行为的综合模型，该模型与功能分析的核心原则保持一致。
