Abstract: This double-blind, placebo-controlled, within-subjects (N=17) experitment compared the sensitivity to change of the cognitive performance and mood measures of mental energy following consumption of either a moderate does of caffeine (200 mg), a small amount of carbohydrate (50 g white bread), or both. Caffeine improved mood and performance. The sensitivity to change of the mood and cognitive measures did not differ in response to the three treatments (all p values> .05). The mood and cognitive measures of mental energy used here have similar sensitivity to detecting change in response to caffeine and carbohydrate.
