Research has shown that schizophrenia patients are less able to identify a situation's abstract features (goals) than its concrete features (actions). However, it has been unclear whether this differential deficit represents a cognitive dysfunction or a lack of familiarity with many situations because of impoverished social experiences. Twenty-nine inpatients with DSM-III-R diagnosis of schizophrenia completed the Situational Feature Recognition Test, Version 2 (SFRT-2). The SFRT-2 included familiar and unfamiliar situations of which subjects were asked to identify characteristic goals and actions. A 2 x 2 x 2 analysis of variance (group by feature abstraction by situational familiarity) found a significant three-way interaction. Post-hoc analyses suggested that patients were better able to recognize concrete features in familiar situations. Differences in discriminating power of the four conditions of the SFRT-2 had been diminished on standardization and cross-validation groups. Therefore, the differential deficits shown by the patient sample probably do not represent psychometric confound. Implications for remediation of social cognitive deficits are discussed.
研究表明，与精神分裂症患者识别情境的具体特征（行动）相比，他们识别情境的抽象特征（目标）的能力较弱。然而，目前尚不清楚这种差异缺陷是代表认知功能障碍，还是由于社会经历匮乏而对许多情境缺乏熟悉度。29名被诊断为DSM-III-R精神分裂症的住院患者完成了情境特征识别测试第2版（SFRT-2）。SFRT-2包括熟悉和不熟悉的情境，要求受试者识别其中的特征目标和行动。一项2×2×2方差分析（组别×特征抽象度×情境熟悉度）发现了显著的三因素交互作用。事后分析表明，患者在熟悉的情境中更能识别具体特征。在标准化组和交叉验证组中，SFRT-2四种条件的辨别力差异有所减小。因此，患者样本所显示的差异缺陷可能并不代表心理测量上的混淆。本文还讨论了对社会认知缺陷进行补救的意义。
