This is an extension of a paper published earlier. We investigated the association between the tendency to detect speech illusion in random noise and levels of positive schizotypy in a sample of 185 adult healthy controls.
Subclinical positive, negative and depressive symptoms were assessed with the Community Assessment of Psychic Experiences (CAPE); positive and negative schizotypy was assessed with the Structured Interview for Schizotypy-Revised (SIS-R).
Speech illusions were associated with positive schizotypy (OR: 4.139, 95% CI: 1.074-15.938; p = 0.039) but not with negative schizotypy (OR: 1.151, 95% CI: 0.183-7.244; p = 0.881). However, the association of positive schizotypy with speech illusions was no longer significant after adjusting for age, sex and WAIS-III (OR: 2.577, 95% CI: 0.620-10.700; p = 0.192). Speech illusions were not associated with self-reported CAPE measures.
The association between schizotypy and the tendency to assign meaning in random noise in healthy controls may be mediated by cognitive ability and not constitute an independent trait.
这是对先前发表论文的扩展。我们在185名成年健康对照样本中，研究了在随机噪声中检测言语错觉的倾向与阳性分裂型人格水平之间的关联。
采用精神体验社区评估量表（CAPE）评估亚临床阳性、阴性和抑郁症状；采用修订版分裂型人格结构化访谈量表（SIS-R）评估阳性和阴性分裂型人格。
言语错觉与阳性分裂型人格相关（比值比：4.139，95%置信区间：1.074 - 15.938；p = 0.039），但与阴性分裂型人格无关（比值比：1.151，95%置信区间：0.183 - 7.244；p = 0.881）。然而，在对年龄、性别和韦氏成人智力量表第三版（WAIS-III）进行校正后，阳性分裂型人格与言语错觉之间的关联不再显著（比值比：2.577，95%置信区间：0.620 - 10.700；p = 0.192）。言语错觉与自我报告的CAPE量表测量结果无关。
在健康对照中，分裂型人格与在随机噪声中赋予意义的倾向之间的关联可能由认知能力介导，并非独立特质。
