Reaction Paper 1 (Sample Reaction Paper) Ron Gerrard, HWS Psychology Department My paper is based on an article from the text’s web site (chapter 9) entitled “Lack of sleep ages body’s systems.” The basic claim of the article is that sleep deprivation has various harmful effects on the body. The reported effects include decreased ability to metabolize glucose (similar to what occurs in diabetes) and increased levels of cortisol (a stress hormone involved in memory and regulation of blood sugar levels). The article also briefly alludes (in the quote at the bottom of page 1) to unspecified changes in brain and immune functioning with sleep deprivation. Intuitively, these results make a lot of sense to me. I know that when I’m sleep deprived for any significant amount of time, I begin to feel physically miserable. I also seem to be more vulnerable to colds and other physical ailments. In thinking about it though, most of the times I’m sleep deprived are also periods of psychological stress (such as finals week). To the extent that there are changes in my physical well-being, I’m wondering whether they are due to the sleep deprivation, the stress itself, or some combination of the two. In principle, a careful 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 night’s sleep (eight hours in bed) the first three nights of the study, followed by a period 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 author’s compare the sleep deprivation stage only to the sleep recovery stage, not to normal sleep. This seems to me like doing an experiment on drunkenness and comparing the drunk stage to the hangover stage, without ever reporting what happens when the person is sober.
The article "Causes and consequences of sleep deprivation in hospitalized patients" written by Stephanie Pilkington is exploring the causes and consequences of sleep deprivation in hospitalized patients. The author provides a brilliant summary of factors that affect the level of sleep experienced by patients in hospitals and the effects of sleep deprivation on the health and the wellbeing of these individuals. The article goes on to state that for sleep-deprived patients, there were bio-cognitive consequences for their health and recovery, with particular effects on immune functioning, inflammation, parasympathetic equilibrium, carbohydrate metabolism and cognitive performance.
Another theory for why we sleep is based on the belief that sleep in some way serves to restore what is lost in the body while we are awake. Sleep provides an opportunity for the body to repair itself. In recent years, these ideas have gained support from evidence collected in human and animal studies. One of these studies have shown that animals deprived entirely of sleep lose all immune function and die in just a matter of weeks. This is further supported by findings that many of the major restorative functions in the body like muscle growth and repair, as well as bone growth mostly happen during
The first research study that I chose dealt with the adverse effects of sleep deprivation on the physical human, such as muscle fatigue and muscle power. Abedelmalek et al (2014) conducted an experiment that tested hypothesis regarding the consequences of partial sleep deprivation on short term, high energy performances for mean power and peak power. In this study the participants were: 36 healthy football players 12 white Tunisians, 12 black Tunisians, and 12 South Africans. Who all shared relatively similar characteristics based on their socioeconomic class, lifestyle, culture, eating, and sleeping habits. In addition, all participants had no history or signs of a sleep disorder, refrained from smoking, consuming caffeine or alcohol, and were not taking any medications. After
One of the most common forms of chronic conditions is cardiovascular disease. This disease is commonly known to disrupt the normal function of the brain. From heart disease, many things can happen, for an example, heart attack and stroke. Although rare and not very commonly known they do happen from lack of sleep and sleep deprivation can be one of the leading cause to a heart attack or stroke if cardiovascular diseases is formed. Not only can a cardiovascular diseases be found, but obesity can also happen. It may seem pretty odd that obesity can happen due to the lack of sleep, but it happens by the lack of brain function and then releases certain hormones that will increase your appetite causing you to gain weight. Once you gain a reasonable amount of weight many aspects of your life will be affected, such as physical activity, and self hate. Obesity, increases many other health risk such as diabetes and breathing problems. Although depressing, if issues relying on sleep are not handled properly, people are risking early mortality. At this stage, they are no longer just affecting their self, but also everyone else around them. People no longer become their own issue but also the family and friends around them, because if they become sick enough the people around them will need to help them and care for them. When dealing with sleep deprivation, make sure to handle it correctly
In recent years, there have been studies on beauty sleep and the perceived health, attractiveness of sleep deprived people. Researchers try to ascertain what happens to individuals when they get a good nights sleep and when they are sleep deprived. What happens to the body when it doesn’t get a full nights rest? It is known that when the body is at rest and in deep sleep, it will restore itself. If someone doesn’t get a full nights rest, they didn’t give their body a chance to repair and the person will appear to look unhealthy. "Poor sleep also equals slower cell turnover, which leaves your skin less glow-y, and can accelerate the signs of aging. In the deepest stages of sleep, your body goes into full-on restoration mode, secreting growth hormones that work to repair damaged cells. Not enough deep sleep means not enough growth hormones and not enough cell repair."(Denise) It is common knowledge that having a full nights rest has positive effects to the body, but does this positive effect also reflect according to the persons appearance? Are people able to perceive that someone is sleep deprived or not?
Many studies of the role of sleep are partial or total sleep deprivation studies which support Oswold’s restoration theory. One of these supporting studies was Dement’s. He deprived participants of REM sleep and consequently found that they increased their number of attempted REM stages from 12 to 26 over 4-7 nights. During their first uninterrupted night, participants increased their REM sleep by 10% which is known as REM rebound. This suggests the importance of REM and the possibility that the purpose of sleep is to get into REM sleep. The participants reported anxiety, irritability and difficulty concentrating which shows that REM sleep is needed to avoid these affects and enable brain recovery which corresponds with Oswold’s theory. Even so, Dement’s study has low ecological validity, it has low population validity because there were only 8 participants and they were a self-selected sample. Participants would probably have shown demand characteristics because the experiment took place in a lab. It also has low mundane realism because people would not usually sleep in a lab and be interrupted repeatedly.

Bio-Psychologists study the principles of biology as it relates to the comprehension of psychology in the field neuroscience that underlies ones emotions, ideology, and actions (Brittanica). Based upon the conduction of research, the relationship between the brain and ones behavior extends to the physiological process in one’s intellect. Scientists are cognizant that neurotransmitters function as a significant role in mood regulation and other aspects of psychological problems including depression and anxiety. A biological perspective are relevant to psychology in three techniques including: the comparative method, physiology, and the investigation of inheritance (Saul Mc. Leod).
Sleep deprivation is a commonplace occurrence in modern culture. Every day there seems to be twice as much work and half as much time to complete it in. This results in either extended periods of wakefulness or a decrease in sleep over an extended period of time. While some people may like to believe that they can train their bodies to not require as much sleep as they once did this belief is false (1). Sleep is needed to regenerate certain parts of the body, especially the brain, so that it may continue to function optimally. After periods of extended wakefulness or reduced sleep neurons may begin to malfunction, visibly effecting a person's behavior. Some organs, such as muscles, are able to regenerate even when a person is not sleeping so long as they are resting. This could involve lying awake but relaxed within a quite environment. Even though cognitive functions might not seem necessary in this scenario the brain, especially the cerebral cortex, is not able to rest but rather remains semi-alert in a state of "quiet readiness" (2). Certain stages of sleep are needed for the regeneration of neurons within the cerebral cortex while other stages of sleep seem to be used for forming new memories and generating new synaptic connections. The effects of sleep deprivation on behavior have been tested with relation to the presence of activity in different sections of the cerebral cortex.
Public Safety Officials have been battling the difficult question of profiling for quite a while. The question is how do they know the suspected individual fit the category associated with an offense? While it has been proven that many profiling cases are somewhat directed to a racial profile, it can be proven that people, given the discretion, are able to identify explanations for a series of behavioral events by identifying what that behavior accredits to. This theory, identified by Frite Heider, “suggested that we have a tendency to give casual explanations for someone’s behavior, often by crediting either the situation or the person’s disposition,” called the attribution theory. Until recently, a study of the like was considered to be a branch of sociology and not a form of psychology. Social psychology essentially became the focus on the individual rather than the group as a whole. Many thoughtful ideas are collected in response to the studies of social psychology. Human cognition is understood to arise from interacting socially; highlighting the importance of socialization. We use social cognition to develop our explanations and our ideas on why a person’s behavior is/does what it is/does.
At first, people's eyes begin to feel dry and they have trouble concentrating, causing their eyesight to weaken. Their reaction time slows down as well as their thinking process and judgment. These effects are minor but as one’s body weakens, their immune system is affected as well. This may cause their body to catch an illness or disease. Afterwards, their body becomes very weak and it will take a while before it can heal properly. In addition, their heart gets tired and cannot perform its job properly, so prolonged sleep deprivation also leads to risk of heart diseases. Not only does sleep loss make people feel tired, but it is also harmful to their body by increasing the risk of health problems (“Sleep Deprivation: What Are the Physical Effects” , Griffin R. Morgan, Mann Jeff, Peri Camille, Pietrengeelo
I never noticed how much psychology could be incorporated into everyday life. But really, any decision or action you take is related to it. I have personally been extremely interested in social psychology: why people do things because of social norms, what people do in order to look socially acceptable, etc. Others topics I also find interesting are sensation and perception; how past experiences can influence how you perceive the things around you, states of consciousness; how things that have happened in your day can be transferred into a mash of events in your dreams, motivation and emotion; what makes a person do something or what makes a person start or stop procrastination, and lastly: personality; what characteristics and traits stand out the most in a person, what makes a person who they are.
Sleep deprivation can affect people of all ages, races, and ethnicities but there is a certain group of people that are more likely to get sleep

One of the more popular areas of psychology is Educational Psychology. Educational Psychology can be explained several ways. The idea is to study theories and concepts from different parts of psychology and apply them in educational settings. These educational settings may occur in different school settings such as preschool. The goal of educational psychology is to create a positive student-teacher relationship. Educational psychology uses five different types of psychology, behavioral, cognitive, developmental, and social cognitive, and constructivist in this research paper I will be briefly discussing each type of psychology listed above.
