Area proportion

The relation with area proportion (size of the coloured object) appears to be most significant for the heavy / light colour emotional scale. This creates a relationship of meaning between the colour quality heavy / light and the shape quality large / small. (Wang, 2007)

Sawada, Suda and Ishii (2003) investigated the relationships between the characteristics of arm movements (such as speed, strength, directness) and emotional expression. They found anger is depicted with fast and powerful movements.
