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
If such thing was carried out in this experiment, the results would have also been much more accurate.
