Sleep Deprivation Has Adverse Effects On Driving Performance.

Sleep Deprivation Has Adverse Effects on Driving Performance It is difficult to constantly get sufficient sleep due to work and family related circumstances, and an estimated 15-30% of traffic accidents are directly related to driver drowsiness (Howard, Jackson, Kennedy, Swann, Barnes Pierce, 2007). Sleep deprivation has been demonstrated to strongly impair mood, cognitive performance, and motor function as a result of decreasing mental impairment (Durmer Dinges, 2005). Therefore, it will be argued that sleep deprivation substantially interferes with driving performance. This is based on the evidence given by Williamson and Feyer (2005) which found that after long periods without sleep, driving performance reached equivalent to those†¦show more content†¦Alcohol measures were made immediately before and after each test session so BAC could be controlled. The study revealed that sleep deprivation worsens driving performance, particularly speed and accuracy (Williamson Feyer, 2005). The first study followed a precise procedure where strengths can stem from, though there are also limitations that can be addressed. A strength of this study was that participants were given a long break in the afternoon after one test, and had an overnight rest nearby before the next test was commenced (Williamson Feyer, 2005). This would have removed any carry-over effects from one condition to the other, which would have ultimately affected the accuracy of the second test. This is because participants would have been able to receive 7-9 hours of sleep in order to combat sleep deprivation, and also, alcohol would return to nil for the next condition as alcohol concentration declines linearly after five hours of consumption (McKnight-Eily, Liu, Wheaton, Croft, Perry, Okoro Strine, 2011; Paton, 2005). Moreover, another strength is that the three tests were omitted from the second, third, and fourth test sessions of the alcohol condition to allow the absorption of the alcohol (Willi amson Feyer, 2005). These three tests were also excluded from the sleep deprivation study which thus allowed a direct comparison between the two variables. Although it was important that the subjects received a long break after the first test, andShow MoreRelatedHow Sleep Is Needed For Optimum Performance1352 Words   |  6 Pagesduring twelfth grade.
