Research in psychology shows that the use of transference method and self-referral method can regulate and control one’s emotions. Transference method is a method of projecting the bad emotion hidden inside to something or someone in order to seek relief. Psychology believes that when an emotional reaction occurs, there is a stronger focal point of excitement in the brain, at this time if another new focal point or foci of excitement are established, it can offset or dilute the original dominant center. Therefore, when you are emotionally irritated and tense due to excessive mental work, consciously do something else to distract yourself, such as listening to music, walking, playing ball, watching movies, riding bicycles and other legitimate and meaningful activities, can make the nervous and irritable emotions relaxed. Self-suggestion is a method of mental health, psychological prevention and psychological treatment imposed on oneself with words. The purpose is to adjust and control one’s emotions, feelings, hobbies, etc. In layman’s terms, it is self-education and self-persuasion. Words are a unique stimulus for the higher neural activity of human beings, capable of acting on the whole organism through the psyche. Words are not only frightening, but also have the miraculous effect of calming people down. When you feel anxious and bored in the study, you can say to yourself: “Do not be anxious and bored, anxious and bored will not help, only harmful, only hard work, perseverance, in order to succeed.” In this way you will be calm and quiet. Positive self-referral is good for improving your self-confidence, enhancing the courage to overcome difficulties and helping you to get rid of bad moods.
