The Slade model for development of anorexia nervosa proposes that the female may seek success and control in her life by pursuing a thin body through dieting when faced with serious personal problems. Extending upon this model, the present program of research has sought to identify those characteristics of women generally at-risk for anorexia nervosa that would make dieting behavior especially successful, permitting the progression from food restraint into food aversion. The present studies considered whether heightened and stress-related inner stimulation could interfere with the at-risk woman's sensitivity to hunger sensations, thereby decreasing her motivation to eat. A series of analyses conducted within two studies indicated: (1) a relationship between elevated daily stress, concern over being over-whelmed by inner feelings, and a loss of discrimination regarding sources of inner feelings, (2) a tendency to narrow attentional focus when overloaded with excessive internal stimulation, and (3) diminished sensitivity to hunger sensations for women generally at-risk for anorexia nervosa given a narrowed attentional focus.
斯莱德关于神经性厌食症发展的模型提出，女性在面对严重个人问题时，可能会通过节食追求苗条身材来寻求生活中的成功和掌控感。在此模型基础上，本研究项目试图确定一般易患神经性厌食症的女性的那些特征，这些特征会使节食行为特别成功，从而使她们从食物限制发展到食物厌恶。本研究考虑了与压力相关的增强的内在刺激是否会干扰易患厌食症女性对饥饿感的敏感度，从而降低她们进食的动机。在两项研究中进行的一系列分析表明：（1）日常压力升高、担心被内心感受压垮以及对内心感受来源的辨别力丧失之间存在关联；（2）当因过多的内在刺激而不堪重负时，注意力焦点有变窄的倾向；（3）对于一般易患神经性厌食症的女性，由于注意力焦点变窄，她们对饥饿感的敏感度会降低。
