This paper reports two studies bearing upon the role of defensive projection in paranoid conditions. The first study considered a proposal explaining the mechanics of projection. People who use their social environment for standards of comparison in making self-evaluations may distort the social comparison process in the case of a threatening characteristic. False attribution or selective perception may allow a social standard to be shifted toward the negative attribute. Given the modified standard, the characteristic can be minimized or denied. Evidence supporting this hypothesis was found when high projectors (among normals) reported greater use of social comparison in reaching self-evaluation judgments concerning negative qualities. The second study considered the clinical implications of the proposition that defensive projection, defined this way, would be found among those who are more heavily invested in their social environment. It was predicted that reactive paranoid schizophrenics, identified by greater premorbid commitment to their social environment, would use projection; process paranoid schizophrenics, having a greater premorbid history of social withdrawal, would not. This prediction was confirmed. Process paranoids demonstrated the most idiosyncratic free associations to verbal cues, suggesting the autistic (self-preoccupied) quality of their thinking and delusions.
本文报告了两项关于防御性投射在偏执状态中的作用的研究。第一项研究考虑了一个解释投射机制的提议。在进行自我评价时以社会环境为比较标准的人,在面对具有威胁性的特征时,可能会扭曲社会比较过程。错误归因或选择性感知可能会使社会标准向负面属性偏移。基于修改后的标准,该特征可以被最小化或被否认。当高投射者(在正常人中)在对负面品质进行自我评价判断时报告更多地使用社会比较时,发现了支持这一假设的证据。第二项研究考虑了这样一个命题的临床意义,即如此定义的防御性投射会在那些在社会环境中投入更多的人身上出现。据预测,以病前对社会环境的更大投入为特征的反应性偏执型精神分裂症患者会使用投射;有更大病前社会退缩史的过程性偏执型精神分裂症患者则不会。这一预测得到了证实。过程性偏执者对言语线索表现出最特殊的自由联想,表明其思维和妄想具有自闭症(自我专注)的特质。
