DATA: Unraveling the Processes Underlying Statistical Learning Through a 2-AFC Task: The Usefulness of ERPs

One of the most popular tasks for testing Statistical Learning (SL) is the two-alternative forced-choice (2-AFC) task. Despite its widespread use in research, it has come under increasing criticism as it is an offline task in which participants are asked to make explicit judgments about regularities that are expected to be acquired implicitly, allowing other meta-cognitive and strategic factors to affect the results. Here we have collected Event Related-Potentials (ERP) data while participants performed a 2-AFC task after the exposure to an auditory stream made of the concatenation of high- and low-predictable three-syllable nonsense words, first, under implicit, and, subsequently, under explicit conditions to analyze whether the neural responses collected from the 2-AFC tasks performed under more complex conditions provide useful information to deepen our understanding of the processes underlying SL through the use of the 2-AFC task.
