现实监测和选择性注意力已多次被证明在精神分裂症中受到损害。已发现阳性症状与现实监测和选择性注意的缺陷有关。因此，假设现实监控和选择性注意之间存在直接联系。对 32 名精神分裂症患者和 32 名正常对照进行了斯特鲁普测试，作为选择性注意力的衡量标准，并测试了现实监测的三个指标，包括区分：事件与非事件、自我与外部生成的事件以及口头与图片来源。为了进行比较，进行了全局记忆测试。结果表明，精神分裂症患者的现实监控和选择性注意均受到损害，并且这两者在精神分裂症样本中显着相关。相反，选择性注意与两组的记忆效率均没有显着相关。此外，精神分裂症患者的多元回归分析表明，只有选择性注意才对现实监测措施的差异产生显着影响。因此，结果支持选择性注意力缺陷在精神分裂症现实监测失败中的特定作用。
Reality monitoring and selective attention have been repeatedly shown to be impaired in schizophrenia. Positive symptomatology has been found to be associated with deficits in both reality monitoring and selective attention. Therefore, a direct link between reality monitoring and selective attention was hypothesized. Thirty-two schizophrenic patients and 32 normal controls were administered the Stroop test as a measure of selective attention along with a test of three indices of reality monitoring, involving discrimination of: events vs. non-events, self- vs. externally-generated events, and oral vs. pictorial sources. A global memory test was administered for comparison. Results showed that schizophrenic patients were impaired in both reality monitoring and selective attention, and that these two were significantly correlated with each other in the schizophrenic sample. On the contrary, selective attention was not significantly correlated with memory efficiency in either group. Further, multiple regression analyses in schizophrenic patients showed that only selective attention contributed significantly to the variance in reality monitoring measures. Therefore, the results argue in favor of a specific role of a selective attention deficit in reality monitoring failure in schizophrenia.
