Materials Paper, graph paper, meter stick, a pencil, Procedure: 1.I will build two identical paper airplanes. One will be my control airplane that is smaller and the other will be my test airplane the one that is bigger. 2.I will throw my control plane 10 times and I will use a meter stick to measure the distance of…

If 5 cuvettes containing spinach/DPIP solution are covered with different cups so that they absorb light of different wavelengths, then the cuvette with no filter will transmit the most orange light because it has been exposed to all white light and has the fastest rate of photosynthesis, followed by cuvettes under red cups, blue cups, green cups, and finally under the opaque cup because it has been exposed to no white light and has the slowest rate of photosynthesis. Fig. 1 and Fig. 2, which…

Due to the increased number of retractions in the psychology journals and release of the news story of a famed social psychologist fabricating data leading to more than 50 retracted papers in the recent years, there has been a lot of speculation and criticism surrounding the fields of psychology and social sciences. In light of this, a newer initiative called the Reproducibility Project at the University of Virginia reran 100 psychology experiments that were published in three leading psychology…

In the paper "Course scheduling and academic performance", Angela K. Dills and Ray Hernandez-Julian examine the relationship between course scheduling and student achievement, controlling for student and course characteristics. The introduction begins by explaining how higher education courses are generally scheduled and introduces a dataset consisting of student and administrative data from Clemson University. With the use of student grades as a measure of performance, the paper argues that…

 Measurements The LifeShirt, a lightweight shirt made by VivoMetrics with built-in sensors capable of measuring respirational activity, heart rate, and subject posture and activity levels, among other things, was used to measure heart rate (HR) and RSA. RSA is used to determine automatic “cardiac control” by the brain in a subject and is a measurement of changes in heart rate during a respiratory period. HR and RSA were measured every five minutes between the introduction of the subjects to the…

C2A. Preliminary Results: C2A1. Establishment of fear conditioning protocols to study consolidation and extinction of fear memories: Presented below is published and preliminary data to establish feasibility for the proposed studies; the conditioning and extinction protocols are sensitive to manipulations that enhance or impair fear memory storage and the acquisition and consolidation of extinction. We reported (Zhang et al. 2013) that mice given post-training serotonin 2A receptor agonist TCB-2…

Handedness is dominance of one hand over the other , or the unequal distribution of fine motor skills between right and left hands. It refers to the tendency of humans to be more dextrous or skilled with one hand over the other. By self report the rates of right , left and mixed handedness are 56.1%,26.3% and 17.5% respectively. The rate of handedness conversion is 2.7% to 11.8% in prior studies based on the total population including innately right handed people. The rate of conversion of…

The question is the following: Are individuals with dual diagnoses, such as developmental disability and mental disorder less likely to receive appropriate mental health assistance than individuals with a mental disorder only? The statistical analysis that would be used for this research question is factorial ANOVA. According to Sukal…

The hypothesis based on the findings of Latane and Darley (1968) that as the number of participants increased, help would become less likely was somewhat supported. The results in the graph Percentage of people who helped/did not help highlighted that the bystander effect occurred as the smallest group size had the highest help rate of 100%, and the percentage of participants who helped in the group of 19 was higher than that of the group of 35, 10.5% and 2.90% respectively. However, the groups…
