Study 1 showed that well-designed materials induced positive emotions and facilitated comprehension, though transfer performance was not affected by emotional design. Study 2 found that round face-like shapes both alone and in conjunction with warm color induced positive emotions. Warm colors alone, however, did not affect learners’ emotions. Comprehension was facilitated by warm colors and round face-like shapes, independently as well as together. Transfer was facilitated by round face-like shapes when used with neutral colors
