Experimental Design for Hypothetical Research Study
Recent research has emerged which suggests that the ingestion of chocolate may lead to improved cognitive function within the realm of memorization and retention of information. Establishing a conclusive link between certain chemical components found in chocolate and the improvement of memory function would be a significant point of progress for medical science, especially when the impact of Alzheimer's disease, early-onset dementia and other memory-reduction ailments on senior citizens is fully considered. By expanding on the work of Jones and Wilson (2011) -- who improved scoring on math tests two hours after subjects ate chocolate -- it may be possible to identify the particular enzymes released during digestion which serve to alter fundamental aspects of memory. Research published by Wong, Hideki, Anderson, and Skaarsgard (2009) -- which suggests that the impact of chocolate on memory improvement occurs more frequently for women -- can also be integrated into this study to determine whether hormones produced predominately by females are reacting with components found in chocolate to produce the memory improvements which have been recorded.
The hypothesis that a predominately female hormone such as estrogen or progesterone may be reacting with components found in chocolate to produce increased memory improvement would...
This hypothesis would be tested using a one-tailed test to determine whether the effect of chocolate on memory was indeed more prevalent and/or powerful for women. The previously cited research put forth by Wong, Hideki, Anderson, and Skaarsgard (2009) suggests that women are more likely to experienced memory gains after ingesting chocolate; therefore the hypothesis and test is one-tailed. The null hypothesis in this case would be that chocolate effects human memory function on an equal inter-gender basis.
Methods: The sample group of 100 individuals (50 men and 50 women selected from a community college campus) will be randomly divided into five groups of 20, with each group containing 10 men and 10 women. Each group will ingest chocolate before taking a specific academic test -- with no two groups taking the same test, and one group ingesting a chocolate substitute as a control. The same tests will be administered before the actual experiment begins to provide a set of baseline scores for each subject. Identically portioned chocolate bars with the same ingredients will be distributed to each subject either one, two and three hours prior to taking the test, to both echo and expand upon the methodology used in the study conducted by Wong, Hideki, Anderson, and Skaarsgard (2009). Testing will take place…
cited in the Introduction, as the subjects who ingested chocolate before testing showing marked improvements over their baseline scores, while the control group exposed to a placebo chocolate substitute returned results which were nearly identical to their baseline. More specifically, women tested higher than their baseline at each duration interval of chocolate ingestion, and the gains experienced by women were significantly higher (on a statistical basis) than those produced by men. In terms of the previously stated hypothesis, the fact that women were consistently observed to record higher test scores after eating chocolate, and that these improvements consistently outpaced that documented in their male counterparts, would appear to suggest a biological basis for the discrepancy. Additional research must be performed from a molecular analysis standpoint to determine if a link between naturally occurring enzymes in chocolate and hormones like estrogen and progesterone which occur predominately in women. The conclusion to be drawn from this experiment is that chocolate contains a particular chemical capable of interacting with the brain on a biological level to stimulate improved cognitive function relating to memory and retention of information. Furthermore, this phenomenon has been observed to occur more frequently and more powerfully in women, suggesting that a component of female biology such as certain hormones may be producing an exaggerated effect. The null hypothesis stated prior to the experiment has been rejected, as chocolate appears to offer genuine benefits for those seeking to improve their ability to memorize facts and retain information.
……Pre-diabetes and Diabetes Early Awareness Education and Its Effects on BMISubmitted by:Nancy L. Gee Comment by Pamela Love: Looks like an interesting project, Nancy.Very good start! Be sure whenever you submit your manuscript that you change wording from �study� to �project� and avoid referring to the project as research. Review carefully for grammar, punctuation, sentence structure, format, or APA errors. Pay close attention to the reviewer�s comments as you continue
A number of daily newspapers reports tales concerning leaders who have failed to deliver the anticipated results. Many people are delighted by leaders who produce the desired results. Moreover, these leaders are frequently commemorated because of their exemplary work. These successful leaders are often imitated by several people. In addition, several people perfect on the conduct of these successful leaders. The daily newspapers and even radio and television stations
Conjoint Analysis Like qualitative researchers, quantitative researchers also have a number of approaches available to them today. The selection of the research approach will depend on what type of information is being sought, what type of information is available, and the goals of the researcher. One research methodology that is gaining increasing popularity is conjoint analysis, a quantitative methodology that is discussed further below, followed by a summary of the research
Of these elements, they found anxiety sensitivity to be directly linked to lower levels of educational advancement. Anxiety sensitivity mainly comprises symptoms of anxiety leading to fear due to a certain belief that anxiety has dangerous somatic, psychological, or social penalties. In one study scholars found that the basic forms of fears were the playing field for a broad spectrum of fear-stimuli and they found that these basic forms of
The trainer will then focus on the steps to be taken to develop new skills. For example, if the trainer wants to talk about motivating, leading, negotiating, selling or speaking, it is best to start with what the learners do well before showing some chart on Maslow's theory, Posner's leadership practices, or selling skills from some standard package that has been develop elsewhere. Many foreign trainers make grave errors
Integration of music and reading may help parents prepare their children for school. On the surface, music and literacy seem opposite of each other both in meaning and delivery. However, the two forms of learning go hand in hand. For example, lyrics and literacy are similar because lyrics are the words sung in a song. Often, they are poetic and can be understood as poetry that sometimes tells a story. Many
