The effects of caffeine on visual selective attention to color: An ERP study

Significant Findings:Caffeine yields a higher overall arousal level, more profound processing of both attended and unattended information, and an acceleration of motor processes.Abstract:"Event-related potentials were recorded from 11 subjects after ingesting caffeine (250 mg) or placebo. Subjects were instructed to...

Does caffeine intake enhance absolute levels of cognitive performance?

Significant Findings:A dose-response trend to improved performance with higher levels of coffee consumption was observed in simple reaction time, choice reaction time, incidental verbal memory, and visuo-spatial reasoning tests.Abstract:"The relationship between habitual coffee and tea consumption and cognitive performance was examined...

Effect of acute caffeine intake on hit accuracy and reaction time in professional e-sports players

Significant Findings:The acute ingestion of 3 mg/kg of caffeine reduced the time taken to react to a simple stimulus, decreased the time taken to hit a fixed target and improved accuracy in hitting the target in a first-person shooting game...

L-theanine, a natural constituent in tea, and its effect on mental state

Significant Findings: L-theanine significantly increases activity in the alpha frequency band which indicates that it relaxes the mind without inducing drowsiness. L-theanine has a significant effect on the general state of mental alertness or arousal. Alpha activity is known to...

l-Theanine and caffeine improve target-specific attention to visual stimuli by decreasing mind wandering: a human functional magnetic resonance imaging study

Significant Findings:"l-Theanine and l-theanine–caffeine combination resulted in faster responses to targets compared with placebo. l-theanine may be decreasing neural resource allocation to process distractors, thus allowing to attend to targets more efficiently." Abstract:"Oral intake of l-theanine and caffeine supplements is known to be associated...
