Recent literature has suggested that deficits in sensory processing are associated with schizophrenia (SCZ), and more specifically hallucination severity. The DSM-5's shift towards a dimensional approach to diagnostic criteria has led to SCZ and schizotypal personality disorder (SPD) being classified as schizophrenia spectrum disorders. With SCZ and SPD overlapping in aetiology and symptomatology, such as sensory abnormalities, it is important to investigate whether these deficits commonly reported in SCZ extend to non-clinical expressions of SPD. In this study, we investigated whether levels of SPD traits were related to audiovisual multisensory temporal processing in a non-clinical sample, revealing two novel findings. First, less precise multisensory temporal processing was related to higher overall levels of SPD symptomatology. Second, this relationship was specific to the cognitive-perceptual domain of SPD symptomatology, and more specifically, the Unusual Perceptual Experiences and Odd Beliefs or Magical Thinking symptomatology. The current study provides an initial look at the relationship between multisensory temporal processing and schizotypal traits. Additionally, it builds on the previous literature by suggesting that less precise multisensory temporal processing is not exclusive to SCZ but may also be related to non-clinical expressions of schizotypal traits in the general population.

多感觉时间加工与分裂型特征之间的关系。

最近的文献表明，感觉处理的缺陷与精神分裂症（SCZ）有关，更具体地讲，与幻觉的严重程度有关。DSM-5向诊断标准的量纲化转变已导致SCZ和精神分裂型人格障碍（SPD）被归类为精神分裂症谱系障碍。由于SCZ和SPD在病因和症状（例如感觉异常）方面重叠，因此调查SCZ中通常报道的这些缺陷是否扩展到SPD的非临床表达上很重要。在这项研究中，我们调查了非临床样本中SPD性状的水平是否与视听多感觉时间处理有关，揭示了两个新发现。首先，较不精确的多感觉时间处理与更高的SPD症状学整体水平有关。第二，这种关系是特定于SPD症状学的认知-感知领域的，更具体地说，是不寻常的感知经验和奇异信仰或魔术思维的症状学。当前的研究提供了一个初步的看法，在多感觉时间处理和精神分裂性状特征之间的关系。此外，它通过暗示不太精确的多感觉时间处理不仅仅属于SCZ，而且还可能与普通人群中精神分裂症性状的非临床表达有关，以此建立了以前的文献。当前的研究提供了一个初步的看法，在多感觉时间处理和精神分裂性状特征之间的关系。此外，它通过暗示不太精确的多感觉时间处理不仅仅属于SCZ，而且还可能与普通人群中精神分裂症性状的非临床表达有关，以此建立了以前的文献。当前的研究提供了一个初步的看法，在多感觉时间处理和精神分裂性状特征之间的关系。此外，它通过暗示不太精确的多感觉时间处理不仅仅属于SCZ，而且还可能与普通人群中精神分裂症性状的非临床表达有关，以此建立了以前的文献。
