M. Iriskulov, A. Kuldashev a course in Theoretical English Grammar Tashkent 2008

A.A. Leontyev, defines the subject matter of psycholinguistics as the 
relationship between language system and linguistic competence. What is meant, 
scholars no longer focus on language as a system, but they also analyze the 
person's ability to use the linguistic units and structures more effectively. 
Psycholinguistics focuses on the speaking individual. Therefore, I. the 
human factor is extremely important in defining psycholinguistics as an 
independent discipline. It is not the product of speaking, that is of greatest 
importance, it is also the speaking person, with all of its strengths, weaknesses, 
creative abilities and disturbances. It is interesting to study the differences between 
women's and men's speech, for example. Men and women are sure to speak 
differently, because their personalities are not the same. Children's speech is 
something to be studied too. It can hardly be denied that teenagers speak somewhat 
differently from senior adults. The speaker's personality type as well as his current 
emotional state can't but affect the choice of language structures. 
II. Another thing is the situation factor. If we look at any text more or less 
carefully, we will see that all the parameters of the communicative speech 
situations are somehow reflected in it. We can basically determine where and when 
this or that conversation takes place. 
III. Experimental factor is important too. The experiment is generally 
recognized as the leading method of psychology. The experiment helps to create an 
artificial situation, allowing the speaker to resort to special linguistic devices, those 
that are of special interest to the scholar. On the other hand, the experimental 
situation may cause the speaker to exercise certain linguistic abilities, so that the 
scholar may determine whether the latter are well developed, underdeveloped or 
impaired. Tests are extremely popular in psycho linguistic studies.
