Observed and Performed Error Signals in Auditory Lexical Decisions.

This study investigates the error processing components in the EEG signal of Performers and Observers using an auditory lexical decision task, in which participants heard spoken items and decided for each item if it was a real word or not. Pairs of participants were tested in both the role of the Performer and the Observer. In the literature, an Error Related Negativity (ERN)-Error Positivity (Pe) complex has been identified for performed (ERN-Pe) and observed (oERN-oPe) errors.

Electrophysiological Correlates of Error Monitoring and Feedback Processing in Second Language Learning.

Humans monitor their behavior to optimize performance, which presumably relies on stable representations of correct responses. During second language (L2) learning, however, stable representations have yet to be formed while knowledge of the first language (L1) can interfere with learning, which in some cases results in persistent errors. In order to examine how correct L2 representations are stabilized, this study examined performance monitoring in the learning process of second language learners for a feature that conflicts with their first language.

Cognate effects in sentence context depend on word class, L2 proficiency, and task.

Noun translation equivalents that share orthographic and semantic features, called "cognates", are generally recognized faster than translation equivalents without such overlap. This cognate effect, which has also been obtained when cognates and noncognates were embedded in a sentence context, emerges from the coactivation of representations in two languages. The present study examined whether cognate facilitation in sentences is subject to effects of word class, reading proficiency in a second language (L2), and task demands.
