Analisys of the influence of alcohol on the motor skills and attention of a driver

Abstract

Alcohol is recognized as one of the factors in the occurrence of traffi c accidents, which signifi cantly aff ects the occurrence of accidents and the severity of their consequences. In this paper, the results of the pilot survey present the measures of infl uence of intoxicated drivers on the status of their motor skills and a en on in traffi c. The eff ect of alcohol is simulated using the "drunk glasses" that simulate the eff ects of the alcohol on the human body: reduced alertness, slowed reac ons, confusion, distor on of the visual fi eld, change of distance and depth percep on, narrowing of peripheral vision, poor judgment and decision making, image duplica on, lack of muscle coordina on and the like. Motor skills were tested using the "Vienna test" system which measures the reac on speed, motor skills, a en on, concentra on and the assessment of traffi c situa ons. For the purposes of this study the results of the "Vienna test" were analyzed -a driver without "drunk glasses" and wearing the glasses. Glasses for alcoholic level of 0,6 -0,8 ‰ were used in the study. Through a compara ve analysis obtained by this research we point to the impact that alcohol has on the perceptual skills of drivers.

Acute Alcohol Intake Affects Internal Additive Noise and the Perceptual Template in Visual Perception

“…For example, a study examined 1,397 patients treated for motor vehicle injuries and found that alcohol-related impairment was strongly related to greater injury in non-admitted patients, even when crash severity was taken into account (Waller et al, 1989). In basic studies, it has been widely demonstrated that eye movements (Watten and Lie, 1997;Harvey, 2014;Tyson et al, 2021), basic perception (Wang et al, 2021), cognition (Silva et al, 2017;Zhang et al, 2020), emotion (Eastwood et al, 2020), and motor skills (Brumback et al, 2007;Petrović et al, 2017) are disrupted by alcohol intake and that the extent of these disruptions depends on the dose of alcohol. Negative effects have been observed even when subjects have low-to-moderate blood alcohol concentration (BAC) (Eckardt et al, 1998;Abroms et al, 2015).…”
