What increases as a result of anger, according to Eckman and colleagues?

The selected answer highlights that both heart rate and skin temperature experience an increase as a response to anger, in alignment with findings presented by Ekman and his colleagues. When a person feels anger, the body's sympathetic nervous system is activated, often referred to as the "fight or flight" response. This activation leads to several physiological reactions designed to prepare the body for immediate action.

An increase in heart rate allows for enhanced blood circulation, ensuring that vital organs and muscles are supplied with oxygen and nutrients. Elevated skin temperature can be attributed to increased blood flow to the surface of the skin as the body responds to the heightened emotional state.

In contrast, while other options mention physiological responses such as blood pressure, cortisol, and blood glucose, they do not encapsulate the broadly recognized immediate effects of anger as well as heart rate and skin temperature do. Therefore, option B provides the most accurate portrayal of typical physiological changes occurring during episodes of anger, showcasing a direct link between this emotional state and specific bodily responses.
