Abstract

Introduction: Hallucinations can be experienced across multiple sensory modalities, but psychiatric studies investigating the cognitive mechanisms of hallucinations have been somewhat restricted to the auditory domain. This study explored the cognitive profiles of individuals experiencing multisensory hallucinations (MH) in schizophrenia-spectrum disorders (SSD) and compared these to those experiencing unimodal auditory hallucinations (AH) or no hallucinations (NH).

Methods: Participants included SSD patients (n = 119) stratified by current hallucination status (NH, AH, MH) and nonclinical controls (NCs; n = 113). Group performance was compared across several cognitive domains: speed of processing, attention, working memory, verbal learning, visual learning, reasoning and problem-solving, social cognition, and inhibition.

Results: The clinical groups performed worse than NCs but differences between the clinical groups were not evident across most cognitive domains. Exploratory analyses revealed that the MH group was more impaired on the visual learning task compared to the NH (but not AH) group.

Conclusions: Preliminary results suggest that impaired visual learning may be related to MH. This could be attributed to the presence of visual hallucinations (VH), or greater psychopathology, in this group. However, replication is needed, as well as the investigation of other potential cognitive mechanisms of MH.

探索精神分裂症谱系障碍中与单模态听觉幻觉和多模态感官幻觉相关的认知特征。

简介幻觉可以出现在多种感官模式中，但调查幻觉认知机制的精神病学研究在某种程度上仅限于听觉领域。本研究探讨了精神分裂症谱系障碍（SSD）患者出现多感官幻觉（MH）时的认知特征，并将其与出现单模态听幻觉（AH）或无幻觉（NH）的患者进行了比较：参与者包括按当前幻觉状态（NH、AH、MH）分层的SSD患者（n = 119）和非临床对照组（NCs；n = 113）。研究人员比较了各组在多个认知领域的表现：处理速度、注意力、工作记忆、言语学习、视觉学习、推理和问题解决、社会认知和抑制：结果：临床组的表现比 NC 差，但在大多数认知领域，临床组之间的差异并不明显。探索性分析表明，与 NH 组（而非 AH 组）相比，MH 组在视觉学习任务中受损更严重：初步结果表明，视觉学习能力受损可能与 MH 有关。结论：初步结果表明，视觉学习能力受损可能与精神障碍有关，这可能是由于该组患者存在视觉幻觉（VH）或更严重的精神病理学所致。然而，还需要进行重复研究，并对精神障碍的其他潜在认知机制进行调查。

期刊介绍： Cognitive Neuropsychiatry (CNP) publishes high quality empirical and theoretical papers in the multi-disciplinary field of cognitive neuropsychiatry. Specifically the journal promotes the study of cognitive processes underlying psychological and behavioural abnormalities, including psychotic symptoms, with and without organic brain disease. Since 1996, CNP has published original papers, short reports, case studies and theoretical and empirical reviews in fields of clinical and cognitive neuropsychiatry, which have a bearing on the understanding of normal cognitive processes. Relevant research from cognitive neuroscience, cognitive neuropsychology and clinical populations will also be considered. There are no page charges and we are able to offer free color printing where color is necessary.
