According to Yerkes-Dodson law ................... is an inverted U-shaped function of arousal, with the optimal .................... level being lower the more difficult tasks.
Performance; arousal
Robert Yerkes and John Dodson (1908), working with mice learning discrimination tasks under electric shock, found that performance first improves as arousal rises and then deteriorates when arousal becomes too high. Performance is therefore an inverted U-shaped function of arousal.
The second part of the law concerns task difficulty: the optimal arousal level is lower for difficult or complex tasks and higher for simple, well-practised tasks. High arousal narrows attention and disrupts complex processing, whereas simple tasks benefit from extra energising.
So the first blank is the dependent variable (performance) and the second is the variable whose optimum shifts with difficulty (arousal); reversing them, or substituting motivation or vigilance, misstates the law.
Hence, the answer is Performance; arousal.
