ResumoBeneficial effects for mood and cognitive performance are believed to influence food and drink choice. The purpose of the present study was to demonstrate a sensitive methodology for providing objective evidence of such effects. A mildly fatiguing repetitive task formed the context for assessing the potential restorative effects of caffeine-containing 'energy' drinks. The methodology used was designed to account for a range of theorised variations in the data, many of which are often overlooked in current research. Significant effects of the energy drinks on task performance and self-rated mood were found. These effects can be summarised with the terms 'alerting', 'revitalising', 'awakening' and providing mental energy, and appear to be mainly caffeine related.
