Distributional learning in adults and infants

1. The experiment
The experiment is described in detail in the following publication:
Wanrooij, Boersma & Van Zuijen (under review; details will follow soon).

2. The dataset
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).

2.1. The EEG recordings
The 39 files with EEG recordings are the files for the adults (= 1 file per participant).
The files for the infants can be found here: http://dx.doi.org/10.6084/m9.figshare.1157812.

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.

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).

2.2. The table
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).
The ID corresponds to the name of the BDF-files.
