<p>Just as problem solving psychology is important, so is problem finding psychology. In the study of problem finding psychology, some key concepts, such as arousal system, tolerance for ambiguity, curiosity and fear, and cognitive sensitivity, have been proposed, which are highly enlightening for the in-depth exploration of problem finding theory.
