FIELD: medicine.SUBSTANCE: invention relates to medicine, namely to psychohygiene, and can be used for estimation of functional lability of optic analyser in solution of problems of children and teenagers' fatigue in the learning process. Examination is carried out in three stages, each of which consists of single-type test tasks with single instruction to tested person. In each test task tested person observes fixed value of frequency of light signal flickers without time limit and makes decision of its perception, both flickering and non-flickering. In test tasks of the first stage tested person is successively shown clearly flickering and clearly non-flickering light signals with explanation of task. At the second stage succession of test tasks with different frequency of flickers is realised, in the first task frequency of flickers is set equal the middle of interval of frequencies, shown at the first stage, and in transition to each following task frequency of flickers is discretely changed by dichotomous scheme towards increase or decrease, if in the previous test task light signal was perceived respectively as flickering or as non-flickering. Value of the first change equals a quarter of difference of frequencies of flickers, shown at the first stage, and in each following change said value is reduced two times until specified error of evaluation is achieved. Frequency of flickers in last test task, if this signal was perceived not as flickering, or said frequency increased by value of said error, if said signal was perceived as flickering, is taken for desired value of CFLF. In test tasks of the third stage tested person is again successively shown clearly flickering and clearly non-flickering light signals, response to which is used to perform control of person's reaction adequacy.EFFECT: method makes it possible to increase reliability of obtained results in examination of people of school age for solution of psychohygiene tasks1 tbl |
