Abstract
This collection contains the data of adult native speakers of Dutch who learned orthographically and semantically similar pseudowords in a multiple-choice learning task, as well as materials pertaining to the study. Half of the learners contrasted similar words, the other half did not. Contrasting occurred in the second (pseudo)language (Experiment 1) or the first language (Experiment 2). The full description of the study can be found in the associated article.
