Pathognomy

Pathognomy is the study of passions and emotions. It refers to the expression of emotions that are indicated in the voice, gestures, and by features.

While physiognomy is used to predict the overall character of an individual, pathognomy is used to gain clues about the current character. Physiognomy is based on shapes of the features, and pathognomy on the motions of the features.
