Effects of collaborative expression using LEGO® blocks, on social skills and trust

In this study, we investigated the psychological effects of an activity for collaborative expression using LEGO® blocks. In particular, we focused on the issues of social skills and trust in 39 high school students. Each participant was asked to answer questionnaires concerning social skills and trust before and after the activity. The results showed that, although trust in oneself did not increase significantly, both social skills and trust in others increased considerably with the help of the activity.
