Is there any evidence that a little bit of inner anger is healthy when engaging in problem solving? I personally feel this way, but feel that people around me misinterpret my anger as being directed at them and the world around me instead of at the problem I'm trying to solve. Thanks.
According the the Yerkes–Dodson law, a moderate level of arousal gives energy to the task, improving performance.
The Yerkes–Dodson law is an empirical relationship between arousal and performance, originally developed by psychologists Robert M. Yerkes and John Dillingham Dodson in 1908. The law dictates that performance increases with physiological or mental arousal, but only up to a point. When levels of arousal become too high, performance decreases.
Anger is an emotion that creates arousal, but it is also a negative emotion that makes other people more hostile and negative. Other emotions that create positive arousal are excitement, interest, curiosity etc.
