Final answer:
The term for the situation described is learned helplessness, which refers to a psychological phenomenon where individuals believe they have no control over a situation.
Step-by-step explanation:
The statement "anger evaporates" accentuates the fact that Edwin hates losing and not having control of the situation. This can be termed as learned helplessness.
Learned helplessness refers to a psychological phenomenon where individuals believe they have no control over a situation, leading them to give up and become passive when faced with negative events.
This concept was first studied by psychologist Martin Seligman who conducted experiments with dogs. In these experiments, dogs were subjected to electric shocks that they could not escape.
As a result, when given the opportunity to escape later, most dogs gave up and accepted the shocks, showing signs of learned helplessness.
Similarly, when Edwin feels that he is losing and has no control over the situation, he may experience learned helplessness, leading to a sense of anger and frustration.
