Question

Based on this graph, what type of relation exists between physiological arousal level and test performance?

a. There is no relation between age and reaction time b. Linear

c. Curvilinear

d. It is not possible to tell, given the information in the graph.

11.      Which of the following best captures what the graph (Physiological Arousal Level and Test

Performance) depicts?

a. There is no relation between physiological arousal level and test performance.

b. There is a linear relation between physiological arousal level and test performance, such that test performance increases with increased physiological arousal level.

c. There is a linear relation between physiological arousal level and test performance, such that test performance decreases with increased physiological arousal level.

d. Test performance increases as physiological arousal level increases, becoming its

best at a moderate arousal level, but after that point, test performance decreases as physiological arousal levels increase.
