Rare Earth hypothesis

The most commonly reported problem associated with the early onset use of marijuana, is verbal memory deficits. These deficits can last up to six weeks after an individual stops using marijuana (Schweinsburg et al., 2008). The researchers conducting this study were trying to prove a connection between learning inefficiencies, and the memory deficits due to early onset marijuana use. The researchers believe that the verbal memory deficits are due to learning inefficiencies brought on by early…

Discussion The research study had a different outcome than what was expected. There was no significance between a person’s mood state and the type of words recalled. As expected, subjects did recall more positive words more than negative words, but it wasn’t significant. No significance was found between positive mood and the critical positive lure word. Unexpectedly, subjects with a negative mood were more likely to recall a positive lure word. Negative mood and the negative lure word were not…

normal term theory, a scientific theory must be backed by evidence. In general, the term theory suggests an idea with evidence or proof to back it up. A hypothesis is an idea that hasn’t been proven yet and, according to the Merriam-Webster Dictionary, every scientific theory begins as a hypothesis. If evidence is then accumulated to support the hypothesis, then is begins a theory as it has evidence to support the belief. Evidence linked to theory can involve observations, experiments and…

table. 5)Measure 400mL of water with a graduated cylinder. 6)Add it to your cup. 7)Carefully place your egg in the cup and allow it to sit for 24 hours. 7)Hypothesize what you think will happen to the size of the egg and record in a data table. Hypothesis Vinegar- If an egg is placed in vinegar, then the mass of the egg will increase because the shell will soften. Syrup- If the egg is placed in syrup, then the mass will restore to normal because the syrup is thick and it will push the…

Discussion: My first hypothesis that the sepia eye and ebony body experimental cross would result in a 9:3:3:1 ratio, and that the traits would be autosomal, unlinked recessive, was found to be false. I chose to reject my hypothesis because my calculated test statistic, 587.5, was larger than the critical value, 7.815. The traits, ebony and sepia, are linked, seeing that they fit in 2:1:1 linkage ratio and that the recombinant number is smaller (Table 1.1). They are autosomal; the amount of…

Hypothesis: Individuals who prefer high fat and sugar foods will priorities attention to images of these foods and therefore have a significant increase in their response time, compared to those who do. Those whom received a high preference of high fat foods in the pre-test will score significantly higher in the questionnaire in the post-test, with a longer reaction time in the odd one out task, indicating that after exposure to food stimuli these individuals attention was impaired. Method…

In our study, we had two controls that we placed the Lumbriculus variegatus into. First, we used spring water to get the normal heart rate of the worms. The other control was a caffeine solution that served as our positive control. Our other solutions that we exposed the worms to consisted of increasing concentrations of two different NSAIDs (ibuprofen and aspirin). For each NSAID, we had a solution equivalent to the recommended dosage for a person based on body weight (the proportional dosage…

to have adequate research, one needs to provide a hypothesis to have validity. He argued that if you don’t come up with a hypothesis before you examine the phenomena, you would not be able to test the evidence fully. He states that if you create your theory after finding evidence, there is no way to test the validity of the theory using that evidence. According to Keynes, he stated that those who provide evidence after coming up with a hypothesis essentially will have more weight placed on it as…

Procedure We downloaded a game called “Flappy Bird” onto our cellular devices in order to perform the experiment. Our professor randomly selected 4 participants at a time to participate in our experiment. Each group of 4 participants performed the experiment in a group setting that ran approximately 5 minutes for each group, a total of 20 minutes all together. There were a total of 4 groups in our experiment; 2 groups were the experimental groups and the other 2 were the control groups. We…

there are many things that one should understand. While scientific articles might not always be easy to comprehend, they provide data and evidence based on what the study set out to find. They use different tests and methods to prove whether their hypothesis is correct or not. They are written around a study and are formatted in APA format. Lay articles on the other hand are a brief summary of a study. It reports the findings but does not have any evidence into why that finding is correct. Lay…
