BIO103 Environmental Biology – Effects of Alcohol on Human Coordination Introduction:
Alcohol is known to produce many chronic abnormalities that are attributable to parietal lobe dysfunction. The self becomes aware of the body being a distant object but it feels a strange attachment feeling (Miller et al, 1991). Considerable laboratory research indicates that different levels of alcohol consumption contributes to overall behavioural and cognitive functions and therefore the reason for carrying out this study is to test the effects of alcohol on human coordination. According to Allum et al (1998) Alcohol effects information received by brain receptors causing the working ones to compensate for the defective information processed by unstable receptors. Therefore the aim of this experiment is to examine the effects of alcohol on human coordination through an online coordination game. Method:
Method has been copied from the Environmental Biology Practical Manual (Bowen et al, 2012) with the alterations of: waiting 30 minutes before retrying the coordination exercise after consuming a beverage, replicating baseline tests and final test twice each and having the mean taken from both will give a more accurate result. To replicate this experiment, three test subjects will be needed to participate in the control (grape juice drinkers) and experimental (wine drinkers) sections. The point of having a control group is to compare the results of the wine drinkers to see how they perform under the influence of alcohol compared to performing sober. Genders should be chosen at random although females and males may have differing results due to their alcohol tolerance, body weight and age. Subjects must not consume any alcohol before this experiment. To replicate the experiment completely, one must purchase Yalumba Classic Fruity Wine- Vintage 2011 (11% alcohol) and Fronti Grape Juice (12% sugar) and must download the Klabutung application to test coordination which involves using an elf avatar to direct presents into a sleigh using your mouse and hand, eye coordination. Results:
As shown by the tables in figure 4.1 and 4.3 of Elena’s team (Control Group), all participants were relaxed using their right hand to play the game and were in a great state of concentration. After they drank the beverage, no vital changes in their appearance were noted. The control group as a whole was still relaxed, had a high concentration level and used their right hand to play. The only real difference was that two of the scores 1st male had decreased from 14 to 11 and 3rd females score had increased from 3.5 to 8.5 had dramatic changes in their results while 2nd females results stayed constant (3). As shown by the tables in figure 4.2 and 4.3 of Elena’s team (Experimental Group), there seemed to be a strong correlation between relaxation, concentration, the use of right hand and strong hand/eye coordination. After the alcoholic beverage was consumed, the observations had dramatically changed. The 1st male still seems calm and relaxed but finger movement seems unnatural and his result increases from 19 to 20. 2nd female loses her relaxation and become much more anxious with unneeded body movement (moving legs and hands). Her facial expression changes and she looks like it is becoming more of a challenge for her to play. Saying this, her score increases from 9 to 14. 3rd Male stays relaxed but is much closer to the screen and has random tongue movement throughout the game. His score did also increase from 15 to 22.5 According to figure 4.4, the overall results from the class data shows that more males had participated in the investigation than females. The overall results from both the control groups and experimental groups show that after consuming a beverage, their scores had improved. Discussion:
After examining the effects of alcohol on human coordination through an online computer game, the results have shown that the overall trend of the data...
