Abstract: This double-blind, placebo-controlled, within-subjects (N = 18) experiment compared the sensitivity to change of cognitive performance and mood measures of mental energy following consumption of either 100 or 200-mg caffeine or a 440-calorie breakfast. Breakfast and 200-mg caffeine improved mood and cognitive performance. The sensitivity to change of the measures did not differ in response to any treatment (all p values > .05). The mood and cognitive measures of mental energy used here have similar sensitivity to detecting change in response to a moderate dose of caffeine and breakfast consumption.

Abstract: This double-blind, placebo-controlled, within-subjects (N = 17) experiment compared the sensitivity to change of the cognitive performance and mood measures of mental energy following consumption of either a moderate dose 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.
