Table 1_A proof-of-concept EEG study of responses to peer speech in collaborative learning.docx

Using a multivariate temporal response function approach, the N1 and P2 amplitudes elicited by each type of utterance were estimated. The degree of self-regulated learning was indexed by the number of deep-level regulation utterances, and interest in learning was evaluated using subjective rating scores. The relationships between these indices and the N1 and P2 amplitudes were analyzed using linear mixed-effects models.</p>Results<p>The number of deep-level regulation utterances was significantly associated with the N1 amplitude, irrespective of whether the utterances were categorized as deep or surface regulation.

In contrast, subjective interest ratings were significantly associated with the N1 amplitude, particularly in response to deep-level-regulation utterances.</p>Conclusion<p>The N1 component, which is related to auditory attention, showed exploratory associations with self-regulatory behavior and learners’ interest.</p>
