Adjusted power of resting state EEG data in typically fluent and adults who stutter

The data presented here is from a study of 23 fluent speakers and 23 adults who stutter as they sit at rest with their eyes open and during the execution of a syllable repetition task. The data was recorded from 128 channels using EGI geodesic nets. ICA was applied so that component weights were the same for rest and syllable execution. Procedures for conducting ICA, experimental procedures (including a stimulus timeline), and findings of event-related spectral perturbations (ERSPs) in the syllable repetition task and their relationship with syllable repetition accuracy in this dataset can be found here https://doi.org/10.1016/j.neuropsychologia.2024.108906. The data presented here is an analysis of 5 minutes of eyes open resting-state and syllable execution with the same IC weights. The data show relatively lower beta spectral peaks when controlling for 1/f in AWS compared to TFA (see folder Summary data).本数据集所呈现的数据源自一项针对23名流利言语成年人与23名成人口吃者（Adults Who Stutter, AWS）的研究，采集了受试者在睁眼静息状态及执行音节重复任务过程中的脑电信号。数据通过128通道的EGI测地网电极帽（EGI geodesic nets）采集得到。本研究应用独立成分分析（ICA）进行处理，使得静息状态与音节执行任务的成分权重保持一致。关于独立成分分析的实施流程、实验流程（包含刺激时序）、本数据集音节重复任务中事件相关频谱扰动（ERSPs）的研究结果及其与音节重复准确率的关联，可查阅下述论文：https://doi.org/10.1016/j.neuropsychologia.2024.108906。本数据集针对5分钟的睁眼静息态与音节执行任务数据进行分析，且采用了相同的独立成分权重。分析结果显示，在控制1/f成分后，成人口吃者（AWS）的β频段频谱峰值相对低于流利言语成人（Typically Fluent Adults, TFA，详见Summary data文件夹）。
