Psychological suggestion, which refers to the psychological characteristics of a person to accept the influence of the wishes, ideas, emotions, judgments and attitudes of the outside world or others, is the most common psychological phenomenon in people’s daily life. It is a psychological phenomenon in which people or the environment send messages to individuals in a very natural way, and individuals unintentionally receive such messages and thus react accordingly. According to psychologist Pavlov, suggestion is the simplest and most typical conditioned reflex of human beings. In terms of psychological mechanism, it is a hypothesis affirmed by subjective will, not necessarily based, but because its existence has been affirmed subjectively, psychologically it tends to this content as much as possible. We are always receiving external cues in our lives. For example, the suggestive effect of TV commercials on shopping psychology. Unconsciously, advertising messages enter people’s subconscious mind. These messages are repeatedly replayed and accumulated in people’s subconscious. When people shop, the human consciousness is influenced by these advertising messages in the subconscious mind, swaying your inclination to buy. People are suggestible. It is an unconscious self-protective ability formed by people in the long evolutionary process. When people are in an unfamiliar and dangerous situation, they will make a quick judgment by capturing the traces of the environment based on their past experience. This process of capturing is also the process of being suggestible. Therefore, the level of suggestibility of people cannot be judged by good or bad, it is an instinct of people. In order to pursue success and escape from pain, people will unconsciously use various methods of suggestion, for example, when difficulties are approaching, people will comfort each other: “It’s almost over, it’s almost over.” Thus reducing the pain of endurance. When people are pursuing success, they will envision a very beautiful and exciting scene when the goal is achieved. This beautiful scenery then constitutes a suggestion for people, which provides motivation, improves frustration tolerance, and maintains a positive mental state. Hypnosis is a method or technique of mental suggestion. Meditation, yoga, qigong and meditation in religion are all psychological suggestion techniques. In this regard, it is necessary to have a scientific attitude and correctly explain the suggestibility of people. A short story about psychological suggestion: ① The psychological novel “Fresh Air” by British writer Solian tells a story like this: The main character Wilson likes fresh air as much as no one can. One winter, he went to stay in a fancy hotel in Finland. It was a very cold winter, so the windows were closed tightly to prevent a cold front. Although the room was comfortable, but Wilson thought of fresh air can not penetrate a trace, he was very distressed, tossing and turning sleep. At the end, he could not stand it, he picked up a leather shoe towards a glass-like things smashed, heard the sound of broken glass, he went to sleep peacefully. When he woke up the next day, he saw the window intact and the broken mirror frame on the wall. Solian’s novel deals with an important psychological concept, DD implication. ②Wanting Plum and Psychological Suggestion During the Three Kingdoms period, Cao Cao led his troops to crush Zhang Xiu. In July and August, the sun was blazing and there were no clouds. The soldiers were so thirsty that their marching speed became significantly slower, and some weak soldiers even fainted on the side of the road. When Cao Cao saw this, he was very anxious and thought that if this continued, the troops would not be able to reach their destination on schedule and their combat power would be greatly weakened. So he called for a guide and asked if there was a water source nearby. The guide said that the nearest water source was on the other side of the valley and there was still a short distance to go. After pondering for a while, Cao Cao pinned his horse’s belly and quickly hurried to the front of the group, then happily turned his horse’s head and said to the soldiers, “Generals, there is a large plum forest ahead, where the plums are red and must be delicious, let’s speed up our pace and cross this hill to reach the plum forest!” When the soldiers heard that, they could not help but mouth and tongue, and their spirits were greatly lifted, and their pace was much faster. Psychological analysis: Cao Cao, an outstanding military and politician in history, intentionally or unintentionally made use of a very important psychological phenomenon in psychology-suggestion. Suggestion is one of the most common psychological phenomena. It refers to a person or the surrounding environment sending a message to an individual in a verbal or non-verbal way, and the individual unconsciously accepts the message and thus makes a certain psychological or behavioral reaction. According to Russian psychologist Pavlov, suggestion is the simplest and most typical conditioned reflex of human beings. Psychological suggestion is always widely used by people intentionally or unintentionally, such as the famous “Rosenthal effect”, which is a kind of authoritative suggestion, the positive expectation of teachers to children, the appropriate praise of leaders to subordinates, can be like “a large plum forest” described by Cao Cao to soldiers Like Cao Cao’s description of “a large plum forest” to his soldiers, the object of the suggestion is “greatly invigorated, and the pace can’t help but speed up a lot”. Not only Cao Cao, but also every person living in the society can engage in suggestive activities. A positive and well-intentioned state of mind will often give positive hints, so that others get the power to overcome difficulties and make progress; on the contrary, a negative and bad state of mind will make others affected by negative hints, becoming cold, discouraged, retreating, depressed and so on. As the saying goes, “a good word three winters warm, bad words hurt people cold in June,” which is the truth. Therefore, when we find that others may be affected by their own hints, we should also pay attention to the way and degree of hints, and try to make others accept positive, moderate hints.
