The BDI contains 21 items that are rated on a 4-point scale (0-3) which reflect increasing symptom severity and cover areas of depressive symptomology including affective, cognitive, motivational, and physiological symptoms (Bumberry et al.,…

Discussion It can be seen from the experimental data, that the relationship between the difference in initial pressure inside the bottle rocket and the atmosphere, and the vertical height reached by the bottle rocket after 0.1 seconds, is proportional. This is quantitatively demonstrated by the high R2 value of 0.99533 of the graphed relationship, which indicates the likeness of points in a data set to an established trend; where 1 = a perfect relationship. The gradient of 0.0236 in the…

Using the Memory Interference Test (MIT) aggregated database, students can formulate hypotheses based on demographics by studying the number of correct responses and mean reaction time by observing pre-calculated students t-test. This particular assessment…

Hey Mom, I know you’re dying to know how my semester is going so I thought I’d share with you some of the assignments I’ve been working on. I just finished my first chemistry lab project involving drugs! Yes, drugs, but not the ones you’re thinking about. We worked with Sulfanilamide, Phenacetin, Acetaminophen, and your favorite, Caffeine. The goal for the experiment was to determine where the drugs may reside according to their properties. We learned that there are parts in the cell that are…

5.What is the purpose and recommended use of the measure?

The highest score that can occur on this measure is 63 (highest severity of depressive symptoms), and the lowest score that can be achieved is 0. The items were designed to identify symptoms of depression as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth…

The Real Results of the Van Boven/Gilovich Study Does experience provide more happiness than material goods? A research study done by Van Boven and Gilovich (2003) explores this question by surveying and performing experiments on different populations. A press article, written by Dr. Dean (2008), presents an argument on this topic using the study as reference. While the press article conveys a message similar to that of the study, its technical inaccuracies, overgeneralizations, and its claim…

Mind Body Identity The identity theory of mind holds that states and processes of the mind are indistinguishable to states and processes of the brain. it need not hold that the mind is identical to the brain. Idiomatically on a general basis we often say ‘She has a good mind’ and ‘She has a good brain’ interchangeably but we barely say ‘Her mind weighs fifty ounces’. Thus it is about identifying mind and brain as being a matter of identifying processes and maybe states of the mind and brain.…

In the article “The Happiness of Pursuit” by Jeffrey Kluger, multiple tables are provided showing different data and percentages on certain factors of happiness. Looking at the tables on the page title “Got Joy,” there was three in specific that caught my eye. The first being the one labeled “Then and Now” which shows the difference in percentages from 2004 to 2013 in whether people described themselves as optimists or pessimists. The percent of Optimist decreased from 70% to 50%, which can…
