Distributional learning in adults and infants

<strong>1. The experiment<br></strong>The experiment is described in detail in the following publication:<br>Wanrooij, Boersma &amp; Van Zuijen (under review; details will follow soon).<br><br><strong>2. The dataset<br></strong>This dataset consists of EEG-recordings (39 files in BDF-format) and a table (4 files = the same table in four formats: PDF, TXT, CSV and XLSX).<br><br><strong>2.1. The EEG recordings<br></strong>The 39 files with EEG recordings are the files for the adults (= 1 file per participant).<br>The files for the infants can be found here: http://dx.doi.org/10.6084/m9.figshare.1157812.<br><br>Each of the 39 files is a recording of an adult participant’s EEG during a discrimination test after distributional vowel training. In the discrimination test, the mismatch response (MMR) was measured in an oddball paradigm.<br><br>The files were recorded with a Biosemi Active Two system (Biosemi Instrumentation BV, Amsterdam, The Netherlands), and downsampled from 8 kHz to 512 Hz (with Biosemi Decimator 86).<br><br><strong>2.2. The table<br></strong>The table presents the following data per adult and infant participant: the identification number (ID), the age group (infant or adult), the experimental condition as specified by the Distribution Type (unimodal or bimodal) and the Standard Stimulus ([ε] or [æ]), and the results of our measurements as represented in the mean amplitude of the mismatch response (in microvolt).<br>The ID corresponds to the name of the BDF-files.

1. 实验<br>本实验的详细内容已在以下发表成果中详述：<br>Wanrooij、Boersma与Van Zuijen（待审稿；详细信息将于近期公布）。<br><br>2. 数据集<br>本数据集包含脑电（electroencephalogram, EEG）记录文件（共39份，格式为BDF）与一张数据表（含4份不同格式的副本：PDF、TXT、CSV及XLSX）。<br><br>2.1 脑电记录<br>该39份文件均为成人被试的脑电记录（每名被试对应1份文件）。<br>婴儿被试的脑电记录文件可在此获取：http://dx.doi.org/10.6084/m9.figshare.1157812。<br><br>每份文件均记录了1名成人被试在分布元音训练后的辨别测试期间的脑电信号。本次测试采用Oddball范式（oddball paradigm），旨在测量失匹配负波（mismatch response, MMR）。<br><br>上述文件采用Biosemi Active Two系统（荷兰阿姆斯特丹Biosemi仪器有限公司）录制，并通过Biosemi Decimator 86将采样率从8 kHz降采样至512 Hz。<br><br>2.2 数据表<br>本数据表包含每名成人与婴儿被试的以下信息：编号（ID）、年龄组别（婴儿或成人）、由分布类型（单模态或双模态）指定的实验条件、标准刺激（[ε]或[æ]），以及以失匹配负波平均幅值（单位：微伏）表示的测量结果。<br>该编号与BDF文件的文件名完全一致。
