The stress response is a cascade of physiological changes resulting from activation of the sympathetic nervous system that occurs when one is subjected to a threatening situation. The physiological changes brought about ...

High levels of stress have been shown to negatively impact working memory recall. For many students these levels produced by academic demands could actually hurt test performance (Kuhlmann et al., 2005). To decrease test ...

Physical stress induced by moderate aerobic exercise leads to the release of hormones that increase blood flow and nutrient availability to the brain. Research has shown that these changes could be beneficial for long-term ...

The purpose of our study was to determine the effectiveness of stress balls in reducing the physiological symptoms of stress. We measured changes in heart rate, blood pressure, and skin conductance and compared the differences ...

The purpose of this study is to measure the physiological response when presented with aversive statements compared to agreeable statements while using politics as a vehicle. Using anonymous students from the Spring 2016 ...

Aerobic exercise has many benefits in improving human health. By increasing oxygenated blood flow and glutamate release into the brain, aerobic exercise has been related to improved long-term memory. Additionally, aerobic ...

This experiment examined the relationship between sleep duration and systolic blood pressure, diastolic blood pressure, mean arterial blood pressure, heart rate, and reaction time. We hypothesized that students who averaged ...

Meditative practices have been shown to have many beneficial effects such as performance boosts, relaxation, and reductions in anxiety. Studies among athletes have shown a correlation between enhanced physical ability and ...

Testing the efficacy of polygraphs can be especially difficult because it is hard to make someone lie in the same way one would during a criminal polygraph. We designed a simplified way of creating guilt and detecting ...

A feed-forward response is an unconscious anticipatory response that humans have in preparation to respond to a stimulus before it actually occurs. A fear-inducing stimulus may induce an anticipatory physiological feed-forward ...
