精神分裂症患者在广泛的神经认知领域都表现出缺陷。特别是，语言流畅性方面的缺陷是很常见的。语言流畅性测试是一种神经心理测试，它评估额叶功能或执行功能，但也评估发散思维。然而，很少有研究从发散思维的角度来考虑语言流利性的损害。要考虑发散思维的结构，不仅需要语言评估，也需要非语言评估。我们对26名精神分裂症患者和26名健康对照受试者进行了多项流畅性测试，包括想法流畅性测试、设计流畅性测试和单词(字母和类别)流畅性测试，以评估两组患者的发散思维，并定性评估他们的反应。患者组的智商维持在可接受的最低水平。尽管精神分裂症受试者的注意力和执行功能相对保持不变，但他们在发散思维方面表现出明显的缺陷，在产生需要概念灵活性、观点转换、原创性或新颖性的想法和设计方面尤其困难。对精神分裂症患者发散思维缺陷的研究可能有助于认知和行为康复计划的发展。
Patients with schizophrenia show deficits across a broad spectrum of neurocognitive domains. In particular, deficits in verbal fluency are common. Verbal fluency tests are neuropsychological tests that assess frontal lobe function or executive function but also assess divergent thinking. However, few studies have considered the impairment of verbal fluency from the viewpoint of divergent thinking. To consider the structure of divergent thinking, not only verbal assessments but also non-verbal assessments are indispensable. We administered several fluency tests, the idea fluency test, the design fluency test, and word (letter and category) fluency tests to 26 patients with schizophrenia and 26 healthy control subjects to evaluate divergent thinking in both groups and assessed their responses qualitatively. An acceptable minimal level of intelligence was maintained in the patient group. Although attention and executive functioning were relatively preserved in the subjects with schizophrenia, they demonstrated significant deficits in divergent thinking and had particular difficulty in producing ideas and designs requiring concept flexibility, a conversion of viewpoint, originality, or novelty. Research on deficits in divergent thinking in patients with schizophrenia may contribute to the development of cognitive and behavioral rehabilitation programs.
