Describe the three elements of emotion, and explain how emotions are linked to to many basic adaptive behaviors

What will be an ideal response?

Answer will include that the three elements of emotions are physiological changes, emotional expressions, and emotional feelings. Typical physiological changes that occur with an emotion include changes in heart rate, blood pressure, perspiration, and other bodily stirrings. Most are caused by the sympathetic nervous system and by the hormone adrenaline. Emotional expressions, or outward signs of what a person is feeling, are another ingredient of emotion. For example, when you are intensely afraid, your hands tremble, your face contorts, your posture becomes tense and defensive, and your voice changes. In general, these expressions serve to tell others what emotions we are experiencing. Emotional feelings involve a person's private emotional experience and are the part of emotion with which we are usually most familiar. Emotions are linked to many basic adaptive behaviors, such as attacking, fleeing, seeking comfort, helping others, and reproducing. Such behaviors help us survive and adjust to changing conditions. However, it is also apparent that emotions can have negative effects. Stage fright or "choking" in sports can spoil performances. Hate, anger, contempt, disgust, and fear disrupt behavior and relationships. But more often, emotions aid survival. As social animals, it would be impossible for humans to live in groups, cooperate in raising children, and defend one another without emotions.
