Basic concepts on the topic:
Involuntary attention is concentration of the mind on an object without a plan, without a goal, without willpower.
Voluntary attention is a type of attention, it is a plan, goal, willpower.
The focus of optimal arousal is the physiological basis of attention
The last form of voluntary attention is coordinated attention.
Focus is a shift of attention from one object to another.
Stability - constant attention, stability, long term.
Anxiety is a feature of attention, which occurs when the nervous system is tired or damaged.
1. Concept of attention
The mental activity of the person at the moment, that is, the totality of his needs, is directed towards the dominant motive at the moment. A person is influenced by a lot of external stimuli, the external stimuli corresponding to various needs of a person and the inclinations of different importance for the person and external stimuli. interaction is expressed in the selective nature of mental activity. Being able to choose a certain object inevitably takes place with the participation of attention.
Attention is a cognitive process consisting of directing mental activity and focusing on an object of certain importance for a person. Orientation means selective nature of mental activity, voluntary and involuntary selection of an object. When a student listens to what the teacher is saying at school, he has consciously chosen this activity of listening, his attention is consciously aroused, and he is subordinated to this goal. The direction of the student's mental activity is expressed when the student concentrates on the content of the educational material without being distracted by anything else.
Orientation of mental activity means not only the choice of this activity, but also the maintenance and support of this chosen one. Any pedagogue knows that it is difficult to attract students' attention. For this, it is necessary to use special pedagogical methods. Focusing mental activity on the attention, and its accumulation, like other things that have nothing to do with this activity, means distraction from all activities. Concentration of attention in one place is understood as giving complete attention to this activity, paying more or less deep attention to it. You can flip through a picture book for a quick review. In this case, concentration of attention will not be strong. A more difficult book can be read with the aim of trying to understand every point it makes, and to understand a complex issue from beginning to end, looking at all the interrelationships. Concentration of attention in this state is very strong. For example: A student who is writing an essay for homework sometimes does not hear the speech of others or the sound of the radio at home. Concentration of attention will be strong.
2. Physiological bases of attention
Attention is related to the excitation of certain nerve centers and the inhibition of other nerve centers in the brain, which ensures the separation of stimuli that are important for the object, that is, the direction of mental activity. . Any newly created stimulus, if it has a sufficiently intense tension, creates the corresponding excitation process, this reflex is expressed by the reflex "what is this", as IPPavlov said. This is the physiological basis of simple attention.
Attention can be related to remembering by association and its perception of objects that do not differ from novelty, but that object has gained special importance in the emergency. The law of induction of neural processes discovered by IP Pavlov is important for understanding the physiological basis of attention. According to this law, the processes of excitation that occur in one part of the cerebral cortex cause inhibition processes in other parts of the cerebral cortex. The braking process that occurred in some part of the brain stem leads to the emergence of strong excitation processes in other parts of the brain stem. At every moment of this moment, there is a strong source of excitation that is optimal for the vision process, that is, it moves with great ease. "If it is possible to look at the skull, IPPavlov said, the brain inside it is visible, if the point where the best conditions for optimal strong stimulation are born in the cerebral hemispheres is visible flashing. , when we look at the brain of a person who is thinking about something new and healthy, we see a very strange and quiet shape in the large hemispheres of his brain, the shape and size of which are changing, turning, and flickering from one side to the other. we could see that it was running and moving, and the hemisphere of the brain was pulling the other lands around this bright object a little dimly.
The principle of dominance advanced by AAUkhtomsky is also of great importance for determining the physiological basis of attention. According to the principle of dominance, there is always a dominant center of excitation in the brain, this dominant center of excitation affects the brain at this very moment, and all the changes occurring in it It somehow draws the movements to itself, and as a result, its dominance over other movements increases even more. The nature of the activity of the nervous system is based on the dominance of excitation or the existence of a dominant.
This situation is psychologically expressed in focusing attention on certain triggers and distracting attention from other triggers that are acting at the same time. Serious attention is usually associated with characteristic external expressions. Actions aimed at better perception of things (hearing with fixed gaze) are associated with stopping excessive movements, slowing down breathing, facial movements typical for attention.
3. Types of attention
Attention in human activity is divided into several types:
-
Involuntary attention;
-
Voluntary attention;
-
Divided into coordinated optional attention.
