Alertness testing method based on attention system theory

Abstract

The invention discloses an alertness testing method based on an attention system theory. The method comprises the steps that the alertness level of a testee is collected; continuous alertness, staged alertness and selective attention indexes are obtained, and the corresponding degree of the testee is judged; average reaction time data is obtained; a standard deviation during reaction is calculated; a variable coefficient and a correct rate are calculated; the alertness level of the testee is determined; comprehensively the alertness overall state of the testee, and the like are reflected. According to the method, the attention system theory is creatively applied to the alertness test, the alertness test can be carried out from the dimensions of continuous alertness, staged alertness and selective attention, and the alertness level of the testee can be reflected more visually and comprehensively. The alertness level of the testee is determined by adopting two specific indexes, namely the variable coefficient and the accuracy rate when the testee reacts, and the result is more scientific and accurate. And in combination with a Karolinska Sleepiness Scale, subjective test and objective test of the alertness are organically combined together, so that the test of the alertness is more comprehensive.

Description

technical field [0001] The invention belongs to the technical field of psychological characteristic testing, in particular to a vigilance testing method based on the attention system theory. Background technique [0002] Attention is the pointing and concentration of mental activities on a certain object, and it is a common psychological feature accompanied by psychological processes such as perception, memory, thinking, and imagination. Attention is not just a single concept, but related to many psychological phenomena and cognitive activities. The attention system consists of vigilance network, orientation network and executive control network. The function of the vigilance network is to achieve and maintain the alert state of the brain; the function of the orientation network is to select information from sensory input; the function of the executive control network is to resolve conflicts. [0003] The attention system theory proposed by psychologist Posner divides atten...

Problems solved by technology

According to the analysis of the characteristics of the tested physiological signals, the level of alertness is currently the most widely used means of alertness testing. These alertness tests relying on physiological signals, although the test results are relatively accurate and have certain credibility, but Their test conditions are relatively harsh, they have high requirements for the test environment, the test instruments and test process are complicated, and the applicable environment is relatively limited, so it is not suitable for daily application and promotion.
