Deffenbacher et al did a meta analysis from 21 studies they looked at 18 studies and found that higher anxiety has a negative impact on recall for the eyewitness. A meta analysis is good because it ensures that all the faults in the experiments cancel each other out and the fact that it was from different studies suggests there is a high validity. However by saying this, what type the experiments were are not known. For example if they were predominantly lab experiments then this will lack ecological validity and factors like demand characteristics, experimenter bias and the halo effect may have come into effect. Further support comes from Kohler et al (2002) who gave particpants 50 words and measured the galvine skin resistance (GSR) for the levels of stress.
Although the data are slightly right skewed, because of the large sample size(n=152) our inference on the mean is valid, by the Central Limit Therom. The Box Cox plot suggests a power transformation using a power, p= -0.5 would make the data more shaped like a normal distribution. The Normal Q-Q plot shows the transformed data points lying close to the straight line and the box plot of the transformed data looks symmetric with two outliers. The numerical summary of the transformed data confirms that the transformed data are symmetric (mean=1 and median=1). A Shapiro-Wilk test on the transformed data provides no evidence against the transformed data having come fro a normal distribution (P-value=0.4286).
In the treatment of major depressive disorder there are both arguments saying antidepressants are significantly better than the placebo, and one that say there is little effect using antidepressants compared with the placebo. This question is supported by the points that when treating depression, acute antidepressant mono-therapy has a 40% remission using the placebo-controlled trials, and a 25% remission rate with just the placebo. Many of the randomized studies conducted have shown that there is not much of a difference in MED vs. PBO, ruling out the concern of more care to the placebo patients rather than the ones taking the antidepressants, but there is still the issue of poorly
describes psychological maltreatment as “rejecting, terrorizing, isolating, ignoring, and corrupting” (1986). The authors also theorized that a positive correlation exists between psychological maltreatment and depression, anxiety and anger. Chirchella-Besemer and Motta discussed symptoms of depression, anxiety and anger as having low self worth, emotional problems, suicidal tendencies, embarrassment, regret, and being socially awkward, In the synopsis of the current study section of the article, the authors wrote their hypotheses as being (a) Individuals who were psychologically maltreated would have significantly higher levels of PTSD than those who were not psychologically maltreated. (b) Individuals who were psychologically maltreated would exhibit significantly higher levels of depression, anxiety, and anger than individuals who were not psychologically maltreated. (c)
On the other hand, biological approaches can be credited towards their idea of no cure for mental illness as this is supported by a high relapse rate with illnesses such as depression. Additionally, the biological approach is strengthened for being able to account for endogenous depression, which can often be the most serious, but can be weakened as it fails to offer an explanation for reactive depression in response to a life event. This is due to the biological approach supporting the nature elements of the nature or nurture debate, believing that depression results from a physical cause within an individual. As a result of claiming depression could have a genetic or inherited basis, much of the research supportive of the biological approach is found through family, twin and adoption studies. Studies of families researched by Weissman found that those with a first degree relative suffering depression, are ten times more likely to develop depression themselves, suggesting such illness could ‘run in the family’ or have a genetic cause.
Map A Map B DYLAN RYDERTERA PATRICK TERA PATRICK The inaccuracies that occurred for both Map is fairly low, which means that calculation of the areas was accurate and precise. The Simpson’s rule was applied in Map A. The percentage error is 3.55%, which is more than Map B the use of shapes. This reason for these inaccuracies for Map B is that Simpsons ’rules will integrate curves to determine the area. In Namibia the country is made up of straight border and edgy coast, which meant that some areas will be left out in the calculation.
It was found however that the method of utilizing a calibration curve proved fruitless in determining fluorine ion concentration, as the calculated value of fluoride ion’s in drinking water was 13.29ppm, where the required value by law must fall within the range of 0.9-1.5ppm. Since this calculated value is so ridiculous, the method of standard addition, in which the calculated value of the unknown solution being measured was much higher than the calibration curve (4.81E-3M verses 3.78E-4M), should be a preferred method for calculated low concentration ion solutions compared to that of a linear calibration curve. Introduction: Fluoride is a necessary component in minimizing tooth decay by helping rebuild enamel. Because of this chemicals very effective ability to complete this task, the fluoride ion can be found in toothpaste. The associated salt (NaF) is often put into substances that are utilized every day, such as tap water and certain food products, in order to help prevent dental problems of the general population.
The gamma group, however, performed worse than the baseline, so saying that all Binaural Beats tested improved short-term memory would be incorrect. This study’s conclusions are somewhat consistent with previous studies that tested Binaural Beats. This means that a logical conclusion can be made that some types of Binaural Beats improve the ability to remember words in
Natural and social selection explanation One strength of this explanation is that it explains the persistence of high mortality and ill health in lower social classes. There is also statistical evidence that poor health leads to the decline in social class and occupational status. However, it does not explain how
EPA and DHA, along with decreasing intake of omega-6 polyunsaturated fatty acids have pro-inflammatory properties, e.g. Arachidonic acid. 6. Higher folate intake due to increased folate deficiencies caused by malabsorption and interference of medications that hinder the body's ability to use folate. 7.
