Attention is characterized by the following characteristics: volume, distribution, concentration, stability and alternation. Characteristics of attention reflect the characteristics of a person. Depending on the entire storehouse of mental life, a person's thinking is formed. According to the character of attention, people are divided into attentive, inattentive, scattered. Consciousness as a characteristic of a person should be distinguished from mental states, carelessness and carelessness as temporary mental states are observed in every person, regardless of whether he has developed the corresponding character traits or not. A person who finds himself in a new, unusual environment develops a state of heightened alertness; occurs as a result of a sharp expectation of important events in life, the performance of responsible tasks The state of alertness is characterized by increased sensitivity, clarity of thought, emotional impact, increased speed of mental reactions resulting from voluntary mobilization of forces, calmness and readiness for action. Attention as a personal characteristic, that is, intelligence, is determined primarily by the interdependence of the types of attention. The predominance of voluntary and post-voluntary attention is characteristic of a strong-willed, purposeful person who clearly understands what he needs and why. In this case, deficiencies in the individual qualities of attention (slow switching, poor distribution) are compensated. The predominance of involuntary attention indicates the inner emptiness of a person: his attention is at the mercy of external conditions, voluntary regulation of attention is minimal. Such attention can be characterized as carelessness, its characteristic feature is "unusual lightness of thoughts", shifting from object to object. The reason for inattention can be deep concentration of attention on one subject. In this case, a person who does not distribute attention enough stops noticing what is happening around him. From the appearance of behavior, this person seems to be completely insane. A strong degree of concentration on a single subject is characteristic of thinkers. This distraction is the result of focusing on one object.
