Participants were 103 females who ranged in age from 18 to 23 years old age (M=21.1, SD=1.7) from a small public college in New England. Participants were primarily Caucasian (84.5%), and the other participants were Hispanic (9.7%), African-American (4.9%), and Asian-American (0.9%). Participants were divided into groups of leanness focused sport athletes, nonleaness focused sport athletes, and non-athletes. Leaness focused sport athletes consisted of 32 individuals who participated as members…

The two treatment groups were assessed on the vocabulary and retell probes a third time 2 months after the completion of treatment. The NT group was not administered the maintenance probe at this time because this group started treatment immediately after their posttest. Progress over the three test times (Time 1 = pretest, Time 2 = posttest, Time 3 = 2 months postcompletion) was assessed by means of repeated measures ANOVAs, with Time as the within-subjects factor and Group (MT and BT) as the…

What is Downs Syndrome? Downs Syndrome (DS) is the leading form of intellectual and chromosomal deformity (Sherman et al., 2007), affecting approximately 1 in every 700 babies born each year (Parker et al. 2010). The main physiological aspect and cause of DS is the trisomy of chromosome 21 in which the usual paired chromosome becomes a trio (Patterson, 2009). DS also has a clear clinical presentation from birth with a number of distinct symptoms such as (percentages represent number of DS…

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…

The control was the first row for both amylases. At 0 min. neither one had synthesized anything so this served as the starting point. The independent variable was the temperature; this is what was being changed. The dependent variable was the amylase activity; this is what (should have) changed because of the temperature. The iodine was a marker. It showed whether starch was still present in the wells. From the results, starch was present in all the wells; it was present at every temperature and…

Statistical analysis Each defect was considered as a statistical unit. Primary study outcomes were changes in CAL at the six-month evaluation period. Descriptive data that included mean ± standard deviation (SD) were calculated for clinical and radiographic parameters at baseline and 6 months. Following this, the data were subjected to statistical analysis using the Wilcoxon signed rank test for intragroup comparison and the Mann-Whitney U test for intergroup comparison. The level of…

In relation to the first question, the results showed that subjects in the control group rated their experience somewhat negatively. Subjects in the one dollar category rated their experience statistically more positively in comparison to the control group while the twenty dollar category’s average rating was only minimally higher than that of the control group. Participants in the one dollar group also responded more positively when asked about their willingness to participate it similar…

What is the percentage of change in Reaction Time as age increases? As people increase in age, their reaction time can change as well, either increasing or decreasing. If kids in different age groups measure their reaction time using a test online, then the percentage of change in reaction time will increase with age. There are an abounding amount of things that can affect how fast or slow someones reaction test time is, along with what happens to your body when it is measured and the process of…

model. Instead, “belavg” displays a negative relationship with the hourly wage, which indicates that it is less physically attractive individuals that are experiencing a monetary disadvantage as a result of their appearance. Two other variables of statistical significance are “exper”, indicating a positive relationship between the amount of experience an individual has and his or her hourly wage, and “educ”, which too indicates a positive relationship, but between the amount of education an…

Introduction Prosopagnosia is a cognitive disorder in which facial recognition is impaired, while other aspects of visual processing remains intact (Gruter 2008). This disorder implies that the brain processes visual stimuli differently. 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…
