SU251750A1 - LIGHT PLATE TO DEVICE FOR PROFESSIONAL SELECTION - Google Patents

Description

The invention relates to the field of the study of psycho-physiological reactions to determine the sense of rhythm and molset to be used in devices for professional selection.

One of the main parts of the known devices for professional selection, when special demands are made on the sense of rhythm, is a metronome fixture, defining a certain rhythmic pattern by which the subject's sense of rhythm is determined.

The proposed light panel contains three rows of light bulbs. Moreover, one row contains light bulbs arranged in the order of the spectral components, another row contains light bulbs that are in violation of the order of the spectral components, and the third row contains single-color light bulbs.

Such an embodiment of the light panel, which serves as a metronome device, makes it possible to estimate the threshold of sensitivity in perception of rhythms.

The drawing shows the block diagram of the proposed light display.

The metronome fixture is made in the form of a light panel 1, in which there are three rows of light bulbs 2. In the first row there are eight light bulbs painted in one

color, for example, white. In the second row there are seven light bulbs arranged in a strict sequence of colors of the light spectrum, and in the third row there are seven light bulbs with a violation of the order of colors of the light spectrum. A switchboard 3 panel is installed under the light panel, on which the colored buttons 4 are located, painted in accordance with the colors of the second light bulbs

p yes scoreboard Buttons 4 are for responding to the light signals, and button 5 is white, also on panel 3, for responding to sound and sensory effects on the subject.

The device 3 is connected to a relay system 6, with which the recording device 7 is electrically connected in the form of a two-channel recorder. One channel is for recording a test program, and the other is

to record the responses of the subject. A switching system 8 is also connected to the relay system 6 with a software device 9.

In addition, to the relay system of the connection: a generator of 10 sound vibrations for p. R, Ach of the main signals to determine the rhythm; Sources of rip off. adjustable parameters, such as the source 11 elektrpcheskogo pulse 12 source of major industrial interference, perceived by the subject through naupp-shki. Oscillations and effects of current are perceived by the subject through electrodes and headphones placed on his body. The tape recorder 13 provides the ability to play modulated signals at the amplifier output.

A device for professional selection, equipped with the proposed light panel, works as follows.

The device 9 through the switching system 8 and the relay system 6 sets the subject on the light panel 1 a certain rhythmic pattern that the subject must reproduce by pressing the corresponding buttons 4 or 5 of the switching device 3. In this way, according to the test program, the subject is affected by distracting sudden stimuli characteristic of production such as sound signals, supplied by generator 10 or tape recorder 13, mechanical sensory stimuli modulated through electrodes and sensors ki mechanical oscillation source 12 or the source 11 of the electric pulse, which is included through a system programming device 9 6.

The answers of the subject, as well as the test program, are recorded through the relay system by device 7, for example, a two-channel recorder, where the presented reference and response rhythms are compared in the form of two diagrams.

If we denote the duration of the lamp burning for t, and the time interval between the lighting of the lamps for U, then the structural test program presented to the subject can be represented as follows, subordinating the entire test program to sixteen main options.

The first option, a) On the light panel, only white light bulbs light up, while the duration of the light bulb, while remaining constant for the whole row of light bulbs, gradually increases from 0.5 second to 5 second with each cycle; b) t increases from 0.5 to 5 seconds. But the interval is kept constant. The subject is able to reproduce each time the reference rhythm by pressing the button located under the corresponding light bulb.

The second option. Bulbs do not light up rhythmically (/ offsop), but const.

The third option. Light bulbs mt In the first embodiment, when

4 const t / const

Fourth option. Light bulbs t r in a complex rhythm

t i const ti const

From the fifth option inclusive through the eleventh, the device additionally models sudden distractions, mainly

production stimuli (sound, light or tangible stimulus) one by one or in any combination.

Further, the test program is gradually complicated.

The twelfth variant includes all previous eleven, but using the second row of light bulbs - light bulbs of the color spectrum. The thirteenth variant duplicates the twelfth variant using

the third p yes light bulbs, the color of the buttons do not match the color. The fourteenth variant repeats the previous eleven in sound. In the fifteenth variant, the determination of the sense of rhythm is carried out according to the effect on the sensation. The last option is the repetition of all the options in the complex without and without distracting stimuli.

A professional selection device equipped with a light board does not allow

only determine, register the rhythm feeling, rhythm sensitivity threshold, but also provide the opportunity for subjects to learn how to determine the correct rhythm and the proper functioning of the mechanisms.

Subject invention

A light board to a device for professional selection, characterized in that, in order to assess the sensitivity threshold for perceiving rhythms, it contains three rows of light bulbs, one row containing light bulbs arranged in the order of the spectral components, the other row contains lanterns located in violation of the order of the spectral components, and the third row contains monochromatic light bulbs.
