(1) Good mood will improve the efficiency of brain activity and the speed and quality of cognitive operation. Yerkes-Dawson's law explains the relationship between emotion and cognitive operation efficiency, and different emotional levels are related to different difficult operation tasks. Different difficult tasks need different levels of emotional stimulation.
(2) In difficult and complicated work, a low level of emotion helps to maintain the best operation effect; In the task of moderate difficulty, moderate emotional level is the condition to obtain the best operation effect; In simple work, a high degree of emotional arousal is a condition to ensure work efficiency.
(3) In short, the more complex the activity task, the lower the optimal arousal level of emotion. When we understand the relationship between emotion and operational efficiency, we can better grasp the emotional state and make emotion the driving force of our cognitive operational activities.
(2) disintegration
(1) The negative influence of emotion on cognitive operation is mainly reflected in the disintegration of negative emotion on cognitive activity function. Some negative emotions, such as fear, sadness and anger, will interfere with or inhibit cognitive function. The stronger the fear, the greater the damage to cognitive operation. Examination anxiety is a typical example. The greater the test pressure, the greater the possibility of candidates failing.
(2) Generally speaking, moderate nervousness is the best emotional state in the exam. Too much relaxation or extreme tension will disintegrate students' cognitive function, which is not conducive to candidates' normal level. When a person is sad, it will affect his work or study status, leading to inattention, easy distraction and reduced fluency of thinking.

In the emotional life of ordinary people, pain is often more than happiness. Among the joys, sorrows, loves and hates, positive emotions account for 3/7 and negative emotions account for 4/7.
(2) The influence of emotions on health is well known. Positive emotions contribute to physical and mental health, while negative emotions can lead to various diseases. It is recorded in Neijing, an ancient medical book in China, that anger hurts the liver, likes to hurt, misses the spleen, grieves the lungs, and fears to hurt the kidney. There are many psychogenic diseases related to people's emotional disorders, such as ulcers, migraine, hypertension, asthma, menstrual disorders and so on. Some people suffering from cancer are also related to long-term depression.
(3) A 30-year follow-up study on the relationship between mood and health found that people who were depressed, anxious and irritable when they were young were four times more likely to suffer from tuberculosis, heart disease and cancer than those who were calm. Therefore, positive and normal emotional experience is the condition to maintain psychological balance and physical health.
(C) Emotional signal function

The external expression of emotion is expression, which has the function of transmitting signals and belongs to a kind of nonverbal communication. People can convey emotional information and ideological wishes with certain expressions.
(2) Psychologists have studied the communication phenomenon of English users, and found that in daily life, 55% of information is transmitted through nonverbal expression, 38% through verbal expression and only 7% through words.
(3) Expression is a psychological phenomenon that occurs earlier than words. Babies communicate with people mainly by expression before they can speak. Expressions are more vivid, expressive, mysterious and sensitive than words.
