Reaction Paper 1 (Sample Reaction Paper)Ron Gerrard, HWS Psychology DepartmentMy paper is based on an bind from the texts web site (chapter 9) entitled Lack of forty winks ages bodys systems. The basic claim of the article is that cat calmness release has various harmful mortalal effects on the body. The reported effects involve decreased ability to metabolize glucose (similar to what occurs in diabetes) and increased levels of cortisol (a evince hormone involved in memory and regulation of blood prize levels). The article too briefly every last(predicate)udes (in the quote at the bottom of rogue 1) to unspecified changes in brain and immune functioning with quietus release. Intuitively, these results practice a lot of sense to me. I know that when Im sleep deprived for any significant amount of time, I engender to feel physically miserable. I also seem to be more vulnerable to colds and other physical ailments. In thinking about it though, closely of the times Im sleep deprived are also periods of psychological stress (such as finals week). To the extent that there are changes in my physical well-being, Im wondering whether they are due to the sleep deficiency, the stress itself, or some combination of the two.In principle, a mensural experiment should be able to isolate the effects of sleep deprivation by depriving people of sleep in the absence of stress and other such confounding variables. That seems to be what this experiment does, but as I read the article closely, I found myself unsure that the effects it reports are necessarily due to sleep deprivation per se. I realize that a brief summary article like this does not provide all the details of the experimental methodology, but a couple of things that were reported in the article struck me as curious. The researchers studied physical functioning (cortisol levels, etc.) in men who had a normal nights sleep (eight hours in bed) the first three nights of the study, followed by a peri od of sleep deprivation (four hours in bed) the next six nights of the study, and finally a period of sleep recovery (12 hours in bed) the last seven nights of the study. In reporting the effects on the body (the discussion of glucose metabolism, in the fifth paragraph of the article) the antecedents compare the sleep deprivation stage only to the sleep recovery stage, not to normal sleep. This seems to me like doing an experiment on alcoholism and comparing the drunk stage to the hangover stage, without ever reporting what happens when the person is sober.
