According to the Yerkes-Dodson law, successful performance on a simple task requires __________, whereas successful performance
on a difficult and complex task requires __________ . a) low arousal; high arousal
b) moderate arousal; high arousal
c) low arousal; low arousal
d) high arousal; low arousal
The Yerkes Dodson law explains the relationship between arousal and performance. It was posited by Robert M. Yerkes and John Dillingham Dodson in 1908.
The law asserts that there is a direct relationship between arousal and performance. An increase in arousal up to a certain level will enhance performance, and once the optimal threshold is exceeded, performance will begin to decline.
Thus arousal should be kept at a midpoint as too little causes boredom, and too much causes hyperactivity, so moderate arousal is optimal.
A simple task requires higher arousal because it uses less cognitive function and brain power thus higher arousal is required to keep interest; while a difficult task requires low arousal since it requires higher cognitive function, it requires lots of focus and higher arousal is not good for intense focus as it causes hyperactivity.
