Psychological structure and cerebral organization of speech.


Psychological characteristics of speech

Concept of speech

Language is a system of signs and symbols. Speech is the process of using language. Thus, speech is the realization of language, which reveals itself only through speech. Human speech arises in response to the need to communicate with someone or communicate something.

Speech is a form of communication that has developed historically in the course of the material transformative activities of people, mediated by language.

Human speech activity is closely connected with all aspects of human consciousness. Speech is a factor in a person’s mental development, his formation as a personality. All mental processes with the help of speech become voluntary and controllable. Speech is a mental phenomenon, it is individual and bears the imprint of a given individual’s subjective reflection and expression of objective reality and attitude towards it.

Rice. 34. Functions of speech[30]

According to its many functions (Fig. 34), speech is a polymorphic activity, i.e. in its various functional purposes it is presented in different forms and types (Fig. 35, 36).

Rice. 35. Forms of speech

External speech is a system of sound signals, written signs and symbols used by a person to transmit information, the process of materialization of thought. It can be oral and written.

Rice. 36. Types of speech

Oral speech

– verbal (verbal) communication through linguistic means perceived by ear.

Monologue speech is the speech of one person expressing his thoughts over a relatively long time, or a consistent coherent presentation by one person of a system of knowledge. Monologue speech is characterized by consistency and evidence, which are ensured by coherence of thought, grammatically correct design and expressiveness of vocal means. During preparation, such a speech is spoken out repeatedly, the necessary words and sentences are selected, and the plan for the speech is often recorded in writing. Monologue speech has greater compositional complexity, requires completeness of thought, stricter adherence to grammatical rules, strict logic and consistency in the presentation of what the speaker of the monologue wants to say.

Dialogical speech is speech in which all its participants are equally active. Dialogue speech is the psychologically simplest and most natural form of speech. It occurs during direct communication between two or more interlocutors. It is characterized by remarks exchanged between speakers, repetitions of phrases and individual words after the interlocutor, questions, additions, and explanations.

Written speech

– this is speech through written signs (letter, notes, scientific treatise). It is addressed to a wide range of readers, is not situational and requires in-depth skills of sound-letter analysis, the ability to logically and grammatically correctly convey one’s thoughts, analyze what is written and improve the form of expression.

Inner speech is speech that does not perform the function of communication, but only serves the thinking process of a particular person. With the help of internal speech, the process of transforming thoughts into speech and preparing a speech utterance is carried out. Inner speech is a person’s conversation with himself, which expresses thinking, motives of behavior, planning and managing activities.

The following properties of speech are distinguished: content, understandability, expressiveness, and effectiveness (Fig. 37).

Neuropsychology
is a branch of clinical psychology that studies the brain mechanisms of HMF and the emotional-personal sphere using the material of local brain lesions and other models.

A common task for all areas: the study of brain mechanisms of mental processes.
Areas of neuropsychology:
1. Clinical neuropsychology (for local brain lesions). Objective: to study neuropsychological syndromes that occur when a particular area of ​​the brain is damaged and compare them with the general clinical picture of the disease.

2. Rehabilitation direction – rehabilitation after local brain damage. Objective: restoration of HMFs impaired due to local brain lesions.

3. Experimental neuropsychology – studies disorders of the HMF using experiments. Objective: experimental (clinical and instrumental) study of various forms of disturbances of mental processes in local brain lesions and other diseases of the central nervous system.

4. Neuropsychology of childhood. Specificity of mental function disorders in children with local brain lesions.

5. Neuropsychology of old age (from 45 years old).

6. Neuropsychology of individual differences - profile-lateral organization is studied. Objective: to study the brain organization of mental processes and states in healthy individuals. Answer to the question: is it possible, in principle, to extend the general neuropsychological ideas about the cerebral organization of the psyche, developed during the study of the consequences of local brain lesions, to the study of the cerebral mechanisms of the psyche of healthy individuals. Psychodiagnostics using neuropsychological knowledge for the purposes of professional selection, career guidance, etc.

7. Neuropsychology of borderline states. Analysis of changes in HMF under the influence of psychopharmacological drugs.

8. Psychophysiological direction – HMFs are studied using psychophysiological methods. Subject of neuropsychology

is the study of the cerebral organization of mental processes, emotional states and Personality on the basis of pathology and, above all, on the material of local brain lesions.

Functions of speech

There are a large number of functions for which human speech is responsible:

The communicative function is the reception and transmission of information code between individuals. The communicative function is the most important and fundamental.

The mental function means that information obtained as a result of communication is transferred by the brain to a person’s memory during verbalization.

The expressive function of speech activity gives a person the opportunity to demonstrate his attitude to other objects, phenomena, events, actions, evaluate these events from his subjective point of view, and his emotional state.

The intellectual function of speech gives a person the ability to think. Speech has a connection not only with thinking, but also with human consciousness. This function is expressed in the fact that a person is able to describe the current situation using compact formulations, and vice versa, can quickly understand what the interlocutor is talking about when he succinctly expresses his thought.

The regulatory function is expressed in the fact that a person is able to demonstrate his voluntary, volitional behavior.
