Psychology I / Human Needs and Arousal Theories
Practice question · True or false

The optimal level of arousal is the same whatever the task, which is what makes the Yerkes-Dodson curve a single inverted U.

Hints
  1. What does arousal do to attention?
  2. Narrowing helps a simple task and hurts a complex one.
Show the answer

False

Why

False. The optimum shifts left as difficulty rises: arousal narrows attention, which suits a simple task needing one cue and harms a complex one needing several held together. That second half of Yerkes-Dodson is the part usually forgotten when the curve is drawn.
