Cross-modal Distractor-Induced Deafness (Distractor-evoked ERPs)

Behavioral and EEG data from a cross-modal auditory experiment investigating distractor-induced deafness (DID). Participants completed a rapid serial auditory/visual presentation (RSAP/RSVP) task in which a VISUAL cue signaled the onset of an AUDITORY target embedded in a stream of preceding AUDITORY distractors. Experimental factors include 'distractor number' (0, 1, 3–4, 5–6) and 'cue–target stimulus-onset asynchrony' (0 ms vs. 300 ms), as well as 'probe onset' (present vs. absent). To quantify distractor-evoked EEG activity, one distractor per trial was designated as the ERP probe. In the 3–4 and 5–6 distractor conditions, the probe was the final distractor in the sequence; in the 1-distractor condition, the single distractor served as the probe. Raw EEG recordings, preprocessed data, and trial-wise behavioral responses are provided. Aggregated data files and a detailed README file describing file structure and variable coding are included.

本数据集涵盖一项探究干扰物诱导性失聪（distractor-induced deafness, DID）的跨模态听觉实验的行为学与脑电图（Electroencephalogram, EEG）数据。参与者完成快速序列听觉/视觉呈现（Rapid Serial Auditory/Visual Presentation, RSAP/RSVP）任务：视觉线索将提示嵌入于前置听觉干扰流中的听觉目标的出现时机。实验变量包括「干扰物数量」（取值为0、1、3–4、5–6）、「线索-目标刺激呈现起始异步间隔」（cue–target stimulus-onset asynchrony，取值为0 ms与300 ms），以及「探针呈现状态」（分为呈现与缺失两种条件）。为量化干扰物诱发的脑电活动，每一试次中选取一个干扰物作为事件相关电位（Event-Related Potential, ERP）探针；在3–4个与5–6个干扰物的实验条件下，探针为序列末尾的干扰物；在单干扰物条件下，该唯一干扰物即作为探针。本数据集提供原始脑电图记录、预处理后的数据，以及逐试次的行为反应数据，同时包含汇总数据文件与一份详细说明文件结构及变量编码规则的README文件。
