摘要

背景:典型的成年人最常将注意力集中在他人的眼睛上,而患有自闭症谱系障碍(ASD)的人则将注意力集中在他人的嘴巴上。典型的成年人在诸如垂直线和水平线平分等任务上也表现出视觉空间偏见。因此,面部观察的差异可能与纵向注意力分配的更普遍的群体差异有关。目的:利用垂直线对分和四边形任务评价ASD个体是否比正常个体有更多的向下定向的垂直注意偏倚。方法:我们招募了20名ASD患者和20名年龄(6-23岁)、智商和性别相匹配的对照组。当垂直线被放置在他们的左、右、中以自我为中心的矢状面和冠状面的交叉处时,我们要求这些人在顶部和底部平分和四边形线。测量到真中点和真四点的距离,并比较组间表现。结果:ASD组与对照组在垂线等分和下线等分上无显著差异。然而,当ASD组与对照组比较更高的线四边形时,ASD组表现出更大的向上偏差。结论:不存在与ASD相关的向下垂直的注意空间偏倚,这可能有助于解释这些个体对嘴的注意偏倚。然而,需要进一步的研究来了解这种非典型的垂直向上的注意力偏向是否可以解释与ASD相关的一些症状和体征。

Altered Allocation of Vertical Attention in Individuals With Autism Spectrum Disorder.

Background: Typical adults most frequently orient their attention to other people's eyes, whereas individuals with autism spectrum disorder (ASD) orient their attention to other people's mouths. Typical adults also reveal visuospatial biases on tasks such as vertical and horizontal line bisections. Therefore, the difference in face viewing might be related to a more general group difference in the allocation of vertical attention.

Objective: To use vertical line bisection and quadrisection tasks to evaluate whether individuals with ASD have a more downward-oriented vertical attentional bias than do typical individuals.

Method: We recruited 20 individuals with ASD and 20 control participants matched for age (6-23 years), IQ, and sex. We asked the individuals to bisect and quadrisect lines on the top and bottom when the vertical lines were placed at the intersection of their right, left, and center egocentric sagittal planes and their coronal plane. The distances from the true midpoint and quadripoint were measured, and between-group performances were compared.

Results: No significant difference was found between the ASD and control groups for vertical line bisections or lower line quadrisections. However, when the ASD group was compared with the control group for higher line quadrisections, the ASD group exhibited a greater upward deviation.

Conclusion: There is no downward vertical attentional spatial bias associated with ASD that could help to explain these individuals' attentional bias toward the mouth. However, additional studies are required to learn if this atypical upward vertical attentional bias might account for some of the symptoms and signs associated with ASD.

期刊介绍: Cognitive and Behavioral Neurology (CBN) is a forum for advances in the neurologic understanding and possible treatment of human disorders that affect thinking, learning, memory, communication, and behavior. As an incubator for innovations in these fields, CBN helps transform theory into practice. The journal serves clinical research, patient care, education, and professional advancement. The journal welcomes contributions from neurology, cognitive neuroscience, neuropsychology, neuropsychiatry, and other relevant fields. The editors particularly encourage review articles (including reviews of clinical practice), experimental and observational case reports, instructional articles for interested students and professionals in other fields, and innovative articles that do not fit neatly into any category. Also welcome are therapeutic trials and other experimental and observational studies, brief reports, first-person accounts of neurologic experiences, position papers, hypotheses, opinion papers, commentaries, historical perspectives, and book reviews.
