Mental Worlds Shaped by Neuroarchitecture: The Effects of Indoor Materials on Brain Activity and Emotional Well-Being

Abstract

This research explored how interior materials—natural wood, processed wood, concrete, and metal—influence brain activity, cognition, and emotional well-being in university environments. The study involved 35 participants, using EEG to monitor brain responses, the Stroop test to assess cognitive performance, and POMS test to evaluate emotions, with data analyzed via machine learning and statistical methods. Findings revealed natural wood yielded the best cognitive outcomes (93% accuracy, quick responses), boosted emotional calm (low negativity, high vigor), and fostered neural relaxation. Processed wood showed comparable benefits, whereas concrete and metal correlated with reduced cognition, elevated stress, and emotional disturbance. EEG analysis effectively identified material-specific effects. The study highlights wood’s potential to enhance productivity and mental health in learning and work settings, urging a rethink of material choices in design to improve urban living standards.
