The impact of semantic feedback on functional connectivity during design ideation: a preliminary study

ABSTRACT:

This study aims to examine the influence of semantic feedback on the functional connectivity of students’ brains in design education. We evaluated functional connectivity using EEG. After the instructor provided feedback, we observed a significant reduction in students’ alpha-band activity across 16 channel pairs. It suggests that, after receiving feedback, participants relied more on localized neural circuits rather than on broad, diffuse connections. Semantic feedback potentially facilitates participation in more efficient cognitive processes, thereby assisting design ideation.
