In the process of sociohistorical development, man has formed forms of adaptation to the environment on the basis of differentiated conditioned reflex reactions and arbitrary control of instincts.
In the formation of volitional process there are the following steps:
1) motivation, awareness of the goal and the desire to achieve it;
2) awareness of a number of opportunities to achieve the goal;
3) the struggle of motives and choice;
4) adoption of one of the possible decisions;
5) the implementation of the decision.
With the totality of desires, motives, aspirations, acquiring the character of motivational activity, is the motivational sphere. The motivational sphere includes both conscious (volitional) and insufficiently conscious actions based on various motives (drives, attitudes, etc.).
Willful violations can relate both to the level of motivations for activity and awareness of the goal, that is, the formation of motive, the adequacy of the motives to the personality traits and the situation, and the decision-making, appropriate behavior at all stages of the volitional process.
Symptoms of volitional disorders
Abulia ( dysbulia ) is characterized by a pathological lack of desire and motivation for activity. Abulin is replaced by adynamia, manifested by a decrease or complete cessation of the motor activity of the organism or organ.
Abulia is detected in various pathological processes, very often in schizophrenia, frontal lesions and depression.
Decreased volitional activity can lead to the release of lower actions – automated and instinctive.
Hypobulia is characterized by a decrease in volitional activity, impoverishment poverty, inactivity, lethargy, a decrease in motor activity, and a lack of desire to communicate. These features are often noted in depressive states, schizophrenia. Weakening of attention, impoverishment of thinking, slowing down of speech can be observed in conditions of stupor .
Hyperbulia , in contrast to hypobulae , is characterized by increased activity due to a significant number of motivations for activity, which often change in order to implement them. Hyperbulla is observed in manic states, paranoiac syndrome.
In a manic state, the productivity of activity is usually low due to the rapid distractibility of patients, the rapid change of motives. When paranoid syndrome activity unilateral, due to delusional motives.

The weakening of the self-preservation reflex – the disappearance of the reaction when a real danger arises, with pain stimulation, the distortion of the defensive reflex with mental diseases manifests itself in self-harm and suicidal behavior. Violations of various drives are described in more detail in Section 9 of Part 2 – “Disorders of biological needs”.
Impulsive drives and impulsive actions
Impulsive drives are caused by an irresistible attraction to achieve goals that are inadequate to the real situation, achieved without resistance, but with subsequent critical evaluation. An impulsive action is performed swiftly, as a rule, it is an unmotivated action that lasts a second or a minute; showing a sign of pronounced mental disorder.

Violations of volitional activity
Violations of volitional activity are possible at the decision-making level and at the level of transition to the implementation of the decision taken.
Obsessive doubts. The patient after a struggle of motives – to go to the cinema or to friends makes the decision to go to the cinema, but after this decision, doubts arise again, and so endlessly.
Rigidity of the decision means the absence of its correction and flexibility in accordance with the changed situation. The patient, because of these peculiarities, cannot proceed to the implementation of the decision, since the situation has already changed, and he cannot make another decision considering the situation. This is observed in rigid epileptoid personalities.
The manifestations of volitional activity include the ability to focus on objects of perception. Concentration can be passive and active, peculiar only to a person and expressed in the fact that a person consciously focuses on certain phenomena, turning off, distracting from other events and phenomena.

The exhaustion of attention is observed in organic diseases and asthenic conditions. When attention is exhausted, patients at the beginning of the conversation answer the questions correctly, and then as the exhaustion increases, the answers become less productive. This clearly appears when counting, for example, when a patient is asked to subtract 7 or 17 from a hundred.
