Michael K. Scullin's Research on SWS
I. Intro
Michael K. Scullin was with Washington University in St. Louis when he performed a study called “Sleep, Memory, and Aging: The Link Between Slow-Wave Sleep and Episodic Memory Changes From Younger to Older Adults”. Since previous research has already proven that slow-wave sleep does decline as we get older. This study was conducted to see if the decline of Slow-Wave Sleep (SWS) in older adults is in fact connected to the decline of their episodic memory. Michael Scullin explained clearly and with an open mind why he was preforming this study.
II. Methods
Michael Scullin’s qualitative experimental research consisted of only 57 young adults and 41 older adults participated. After the selection the participants were randomly separated into three groups: 12-hr wake, 12-hr sleep, and 24-hr (night-to-night) sleep groups. Each participant was given a wireless home sleep-stage monitoring device which distinguishes between wake, light sleep, SWS, and REM sleep. sleep stages. The different stages of sleep become the variables for this study. Scullin went with time sampling since he tested each participant at specific times each day. Before they went to sleep they each had to do a word pair learning, and a math test. After completing both they were given a cued-recall test which they had to score at least 80% in order to go to sleep. After the data was collected it was broken down by sleep type, age, and the t and p values refer to the age-group main effect. After reviewing the procedures that Scullin used, I do think that he was through in his methods.

III. Ethical Aspects
All the subjects that participated in this study were pre-screened and made fully aware of what the research entailed and how long this study would last. Michael Scullin did not discuss ethics in his article because of the research that was being conducted safety was not an issue for the participants. As for confidentiality, no one that participated was named in his research only

    Respect for persons means that researchers must obtain voluntary informed consent from participants in the study.

In addition, participants should be able to freely choose to begin or stop the study at any time.(1) The Tuskegee study did not fully disclose information to the participants. They told participants they were being treated for bad blood despite the fact that they were specifically studying the effects…

    There were 9 adults used in this study who were two females and 7 males. The individuals who took part in the study had electrodes on their eyes and scalp so they could measure eye movements and also record the individual’s brain.

There was a recorder that the participants had to speak in. they had to describe what their dream was and if it was either 5 or 15 minutes long. The results were that the individuals experienced rem sleep every night, it was faster. 80% was the mean of dream recall and the non-rem was 7%. This mean that the individuals were good at recalling the dreams in their rem…

    The ethics written are statements which reflect our morals of society. These morals are seen as unwritten codes which exist in society determining what is acceptable or unacceptable in our society. During research, these morals are written regulations which are placed in order to ensure that individuals taking part in the research are treated how they should be treated. Codes of Conduct, or practise for health and social care professionals, do not explicitly include research but the underlying principles of professional practise would be consistent with expectations for ethical research (Mary Whitehouse:Health&Social Care, 2010). The ethical principles that underpins all research include protecting individuals, ensuring that individuals only participate voluntarily and ensuring that any personal information is kept confidential.…

    SUMMARY: On July 12, 1974, the National Research Act (Pub. L. 93-348) was signed into law, there-by creating the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research. One of the charges to the Commission was to identify the basic ethical principles that should underlie the conduct of biomedical and behavioral research involving human subjects and to develop guidelines which should be followed to assure that such research is conducted in accordance with those principles. In carrying out the above, the Commission was directed to consider: (i)the boundaries between biomedical and behavioral research and the accepted and routine practice of medicine, (ii) the role of assessment of risk-benefit criteria in the determination of the appropriateness of research involving human subjects, (iii) appropriate guidelines for the selection of human subjects for participation in such research and (iv) the nature and definition of informed consent in various research settings.…

    Sleep is a big part of one’s psychological health. Without sleep, many of our essential cognitive functions would begin to deteriorate. Factors like mood, comprehension, and many more are affected by the lack of sleep in an exceptionally large way. Due to the fact that in humans, we are exceptionally vulnerable mentally as we are physically. Many of us begin to put our well-being in harm’s way by receiving a reduced amount of sleep when compared to the average needed. As illustrated in, Sleep Thieves, Stanley Coren presents an experiment conducted in 1964 by a seventeen year old named Randy Gardner who became the world’s record holder for the longest amount of time spent awake without stimulants. The book, Sleep Thieves, begins to explain…

    Both sleep, and psychological and cognitive function, are areas of concern that are consistently addressed in older adults, as studies have shown that these two very distinct areas, are actually very closely related. It is said that along with other physical changes in aging, so too does sleep patterns change. Most often, older adults have complaints of difficulty sleeping, or difficulty staying asleep. In this paper I plan to address these two important issues, focusing on more specifically sleep and the connection if any to the development of delirium in our geriatric population.…

    The APA (2010) has 15 codes relating to Research and Publication that supports the ethical practices and behaviors of their members. Among some the highlighted areas regarding the ethical responsibilities of the researcher relates to their interaction with the participants. Lefkowitz (2009) stresses that researchers have an ethical obligation not ensure participants voluntary participate, provide their consent, and their “well-being” is protected. Also, as it relates to the research side of ethics, its psychologist must restrain from “deception” as it refers to the existence, the purpose, and the methodology Lefkowitz…
