Abstract

Visuomotor adaptations are a fundamental property that the human brain acquires in response to intrinsic and extrinsic conditions that are enhanced by focus and alertness. Caffeine is a widely used stimulant that increases focus and alertness. However, there is limited knowledge on how the consumption of caffeine affects visuomotor adaptations. The purpose of this study is to compare how visuomotor learning and transfer are influenced by coffee (5mg caffeine/kg) consumption and the practice effect. Participants were randomly assigned to the experimental group (Coffee + Beatsaber), training-only group (Non-caffeinated coffee + Beatsaber), or the coffee-only group (Meditation + Coffee). Subjects consumed coffee or non-caffeinated coffee 15 minutes prior to testing. Utilizing the Virtual Reality (VR) headset, subjects completed a baseline trial using Audica, a beat rhythm game, on Standard difficulty. The control group consumed coffee and watched a meditation video to promote VR familiarization. The meditation video matched the duration of training time for the experimental and placebo groups. After baseline testing, participants used another beat rhythm game known as Beatsaber, Hard difficulty, to complete 6 trials of training. Preliminary data showed no effects of coffee in learning in Beat Saber (p>0.05). Training in BeatSaber, with or without coffee, did not have an effect on transfer of rhythm game performance on Audica. Preliminary data demonstrated no significant (p>0.05) differences between the three groups. The practice effect may be responsible for the increase in visuomotor learning in both games, while coffee did not elicit a significant difference. All the participants had experience in playing Beat Saber prior to the study, which may have masked the training-related effects.
