Previous studies in language conditioning, especially those called semantic desensitization, have shown changes in self-report, behavioral measures, and the semantic meaning of the target concept following treatment. This last has been proposed as a causal variable but experimental and control groups differed greatly in terms of their demand characteristics. The present study included a placebo group with demand characteristics similar to those of the control group. The target area was self-concept (18 male Ss, 9 female Ss). Significant changes in self-report and actual performance with a hand dynamometer were obtained but these were as great for the placebo group as for the experimental groups. It was suggested that factors other than conditioning are of importance in semantic desensitization.
以往关于语言条件作用的研究，尤其是那些被称为语义脱敏的研究，已经表明治疗后自我报告、行为测量以及目标概念的语义含义会发生变化。后者被认为是一个因果变量，但实验组和对照组在需求特征方面差异很大。本研究纳入了一个需求特征与对照组相似的安慰剂组。目标领域是自我概念（18名男性被试，9名女性被试）。在自我报告以及使用握力计测量的实际表现方面都获得了显著变化，但这些变化在安慰剂组和实验组中同样显著。研究表明，除了条件作用之外的其他因素在语义脱敏中也很重要。
