Task-irrelevant affective prosody perception by children with high autistic traits under attentional loads: electroencephalographic and behavioural data

Impaired social-emotional reciprocity and verbal communication characterise Autism Spectrum Disorder (ASD). This dataset provides electroencephalographic (EEG) signals related to implicit emotional speech perception under low, intermediate, and high attentional demands. Demographic and behavioural data are also provided. Thirty-one children with high autistic traits (mean age: 10-year-old, SD: 1, 2 girls) and their parents or legal guardians participated in data collection. Assessments of autistic behaviours severity using the Autism Spectrum Rating Scales (ASRS, parent report) are provided. During the experiment, children listened to task-irrelevant affective prosodies while answering three visual tasks: neutral image viewing (low attentional load), one-target 4-disc Multiple Object Tracking (MOT; intermediate), one-target 8-disc MOT (high). EEG data recorded during all three tasks and tracking capacity (behavioural data) from MOT conditions are included in the dataset. Beforehand, children answered the Edinburgh Handedness Inventory, and resting-state EEG activity of children was recorded for 2 minutes with eyes open. Those data are also provided. The present dataset can be used to investigate the electrophysiological correlates of implicit emotion and speech perceptions and their interaction with attentional load and autistic traits severity. Besides, resting-state EEG data may be useful for a clinical characterisation of the autistic condition at rest. Finally, behavioural MOT data can be analysed to assess dynamic and selective attentional functions in children with high-autistic traits.

自闭症谱系障碍（ASD）以受损的社会情感互惠和语言交流为特征。本数据集提供了在低、中、高注意力需求下，与内隐情感言语感知相关的脑电图（EEG）信号。此外，还提供了人口统计学和行为数据。三十一名具有高度自闭症特质（平均年龄：10岁，标准差：1，2名女性）的儿童及其父母或法定监护人参与了数据收集。数据集包括使用自闭症谱系评定量表（ASRS，父母报告）对自闭症行为严重程度进行的评估。在实验过程中，儿童在回答三个视觉任务（中性图像观看（低注意力负荷）、单一目标的四盘多目标跟踪（MOT；中等）、单一目标的八盘MOT（高））的同时，聆听了任务无关的情感语调。所有三个任务期间记录的EEG数据以及MOT条件下的跟踪能力（行为数据）均包含在数据集中。在实验前，儿童完成了爱丁堡倾向量表，并记录了儿童睁眼时的静息态EEG活动2分钟。这些数据也一并提供。本数据集可用于研究内隐情感和言语感知的电生理相关及其与注意力负荷和自闭症特质严重程度的相互作用。此外，静息态EEG数据可能有助于对自闭症患者在休息状态下的临床特征进行描述。最后，通过对行为MOT数据的分析，可以评估具有高度自闭症特质的儿童在动态和选择性注意力功能方面的表现。关键词：脑电图、多目标跟踪、选择性注意力、动态注意力、自闭症谱系障碍、情感处理、语调。
