One of the continuing debates about emotions involved what they are. Some people have argued that emotions is simply another term for motivation. Most investigators, however, take the position that although the two concepts may be related, they are not the same thing (Buck, 1985). As we discussed earlier, motivation is generally see as arousal or energy that directs behavior. Emotions, on the other hand, are viewed as the blending of arousal, behavior, and feeling (or cognition). We are hungry, thirsty, or tired, but we feel happy, sad, or afraid. Hence, emotions are affective states (or feeling) accompanied by physiological changes that often influence behavior.
