精神分裂症患者（n= 31），包括偏执型和非偏执型诊断亚组，以及正常对照组（n= 20）参加了一项涉及单项选择词汇决策任务的语义启动实验。对于自动启动模块，使用260-ms的刺激起始时间（SOA）;对于受控启动模块，使用1，000-ms的SOA。偏执亚组的启动显著低于对照组。与对照组相比，非偏执亚组的启动率降低，接近显著性。与自动启动条件相比，对照组的启动效果有所增加;这种差异不受参与者组的调制。无意义的语义启动（等于0）只发生在精神分裂症的亚组，只有在自动启动条件。
Schizophrenic individuals (n= 31), including paranoid and nonparanoid diagnostic subgroups, and normal controls (n= 20) participated in a semantic priming experiment involving a single-choice lexical decision task. For the automatic priming blocks, a 260-ms stimulus onset asynchrony (SOA) was used; for the controlled priming blocks, a 1, 000-ms SOA was used. The paranoid subgroup showed significantly less priming than did the control group. The nonparanoid subgroup showed a decrease in priming compared with the control group that approached significance. There was an increased priming effect for the controlled compared with the automatic priming condition; this difference was not modulated by participant group. Nonsignificant semantic priming (equal to 0) occurred only for schizophrenic subgroups and only in automatic priming conditions.
