Title: Sensitivity to Change in Cognitive Performance and Mood of Energy and Fatigue in Response to Differing Doses of Caffeine or Breakfast

Journal: International Journal of Neuroscience, Vol. 119, No. 7, pp 975-994, 2009 

Abstract

The mood and cognitive measurers of mental energy used in this investigation have similar sensitivity for detecting change in response to a small and moderate dose of caffeine and breakfast.

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).
