Biplot showing the result of K-means clustering analysis with 90% confidence interval.
Each color represents each group of participants, where Group 1 judges faster moving objects as heavier, Group 2 judges slower moving objects as heavier and Group 3 judges slower moving objects as heavier in Environment 1 but faster moving objects as heavier in Environment 2. No participants showed behavior opposite to Group 3. Comparison with our model matching classification method showed no misclassifications.
