Allison Saulsbury Lab Report #1 James Anthony Tuesday 9:00-10:50 a.m. September 18, 2006 Question C- How does reaction time vary in relation to alcohol intake? Through research, I have found that alcohol intake does affect reaction time by slowing down ones reaction time. A Japanese study shows the relationship between the effect on one’s blood alcohol concentration and central nervous system impairment to result in longer reaction time and reduced coordination (Tagawa et al. 2000). These researchers tested adult males by giving them controlled amounts of alcohol and evaluating their reaction times to attention-demanding cognitive tasks (Tagawa et al. 2000). In Kuypers’ experiment, researchers gave subjects alcohol until their blood

Unformatted text preview: alcohol concentration reached 0.06 and had them drive a motor vehicle. As a result, subjects’ driving performances such as brake reaction time and car following (speed/ distance variations) were decreased (Kuypers et al. 2006). Thus, alcohol affected reaction time negatively. In Leung’s experiment, 18-21 year old and 25-35 year old males were given alcohol and put into a driving simulator in order to find if alcohol did influence their driving abilities. Results include, slower detection times and decreased time-to-collision judgment times (Leung et al. 2005)....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
