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 ...

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 ...

This study analyzes and compares several methods of reducing stress following induced anxiety events. The physiological indicators of stress measured in this study are blood pressure, heart rate, and electrodermal activity ...

Past research has shown that people separated from their cell phones exhibit physiological responses related to anxiety. These responses include an increase in the release of stress hormones leading to an increase in heart ...

Car accidents are a leading cause of death that primarily occur at night. There are many characteristics of night time driving that have been proposed to explain this phenomenon. Our group set out to determine if reaction ...

The purpose of this study was to determine if there is a difference between how non-parental males and females between the ages of 20 and 24 respond physiologically to an audio recording of a crying infant. Based on previous ...

College exams are undoubtedly stressful, but when external distractions are present most students would say that it is even harder to concentrate. Distractions could lead to a physiological stress response and potentially ...

This study investigated whether active individuals would be able to better cheat a polygraph test by virtue of a more controlled heart and respiration rate and a lower stress response. The subjects were asked 25 questions, ...

This experiment tested the hypothesis that there are physiological differences that manifest when a person tells a lie compared to when they tell the truth. It was predicted that when a person lies, their sweat production ...
