Abstract

One of the core deficits that characterizes schizophrenia is an increase in distractibility and disinhibition at all levels of information processing. Patients with schizophrenia seem unable to focus attention on the relevant events while ignoring the irrelevant stimuli. This pattern of behavior is also observed in unmedicated schizotypal individuals who may carry liability for schizophrenia. In this review, we focus on studies of attentional inhibition, as assessed by the negative priming paradigm, to elucidate the relationships among deficits in inhibition, clinical symptoms and medication effects. We then consider models of the etiology of deficits in negative priming in schizophrenia and schizotypal personality. Finally, we discuss the potential power of utilizing hypothesis-driven cognitive paradigms in psychiatric research.

精神分裂症和分裂型人格的注意窗口:来自负启动研究的见解

精神分裂症特征的核心缺陷之一是在信息处理的各个层面上注意力分散和去抑制的增加。精神分裂症患者似乎无法将注意力集中在相关事件上而忽略无关的刺激。这种行为模式也可以在未接受药物治疗的精神分裂型个体中观察到，这些个体可能患有精神分裂症。在这篇综述中，我们重点研究了负面启动范式评估的注意抑制，以阐明抑制缺陷，临床症状和药物效果之间的关系。然后我们考虑在精神分裂症和分裂型人格负启动缺陷的病因学模型。最后，我们讨论了在精神病学研究中利用假设驱动的认知范式的潜在力量。
