Many herbicides and pesticides are thought to be involved in teratogenic, or embryonic development disturbing, mechanisms. Therefore it is important to study the effects of these chemicals on humans and wildlife in the event of contact or contamination. Case-Control Study of Maternal Residential Atrazine Exposure and Male Genital Malformations by Agopian in 2012 is one study that examines an herbicide, atrazine, in relation to birth defects of male genital development. Atrazine is one of the…
In the following two studies, Vrij and Mann (2001) and Mann, Vrij, and Bull (2004), respectively, researched police officers abilities to detect deception in real-life, high-stakes scenarios. They also looked at the behavioural cues which were used to come to these conclusions. In the first study by Vrij and Mann (2001), participants were comprised of 52 police officers in the Netherlands, 28 male and 24 female. The officers had an average age of 30, around 9 years of service, and rated…
this chart, there was a positive correlation between the years of high school completed and the income of the respondent. The more years of high school that were completed led to a higher income for the respondent. This was calculated by a Pearson product-moment correlation coefficient. The values that were found were positive with r=0.208, n=906, p=0.000. This is summarized by the scatterplot above. The Sig value strengthens the argument for a positive correlation between years and school and a…
To determine if mood state changed from pretest to posttest a paired samples t-test was calculated on mood state. Mood state changed from pretest (M=27.7, SD=5.8), to posttest (M=30.1, SD=4.8), t (43) = -4.8, p = 0.00. To test the hypothesis that HAI increases mood, a one way ANOVA was calculated. As displayed in table 1, the effects of conditions had no significant difference on mood in people, F (2, 42) = 1.5, p = 0.23. To test the effect of species, a 2 (species) x 3 (condition) factorial…
Introduction: The purpose of this study is to see if there is a link between the birth weight and gestation of newborn babies with smoking mothers and non- smoking mothers. The significance of this investigation is to find a relationship between the two as it might help with health benefits. The features in the investigation are the relationship between the two sets of data between the birth weight and the gestation period of smoking mothers and non-smoking mothers. Part A: The median for the…
Summary The paper “Observant, nonaggressive temperament predicts theory-of-mind development” by Wellman, Lane, LaBounty, and Olson (2011) reports on their longitudinal study, that was run to test the connections between a child’s temperament and their development of a theory-of-mind. Temperament is a multi-layer concept that influence a child’s personality, which influences how they interact with the world. The way that children interact with society and the way society interacts with the child…
However, even though this is the population from which a sample was taken for the research, it may be assumed that ultimately the goal of the study is to define the population as all workers in Taiwan, for purposes of extrapolation of the data. Additionally, only respondents holding a full-time job were selected for the analysis in order to highlight the potential effects of work/family conflict (Lu et al., 2011). Description of Data and Descriptive Statistics A wide variety of data was…
