In this basketball blog, Chase describes how to achieve peak performance by using the Yerkes-Dodson Law of Arousal in his pre-game preparation.
He explains arousal levels and that the ideal place to be is somewhere between the high and low extremes. Does Chase sufficiently explain Yerkes-Dodson Law of Arousal? Where is the curve (higher or lower) in the inverted-U if a task is more difficult? Why?
