This document discusses emotions and moods. It defines emotions as feelings like happiness, love, fear, or anger caused by one's situation or other people. Basic emotions include anger, fear, sadness, happiness, disgust, and surprise. Moods are influenced by personality, time of day, weather, stress, sleep, age, gender, and social activities. People sometimes feel one emotion but display a different one, and emotions that are close on the continuum can be confused. Gender differences exist in the expression and recognition of emotions.
