“…It is possible that BT consumers had learned better in this spatial learning task. This finding goes in line with the caffeine related improved performance in the Berg's Card Sorting Test (BCST) and simple reaction time tasks and supports previous findings that showed caffeine induced facilitation of attention [32,44] and level of alertness [13,45]. It is also consistent with other previous studies [2,16,19,38] that linked consumption of tea to robust increases in alertness and information processing capacity [4].…”

Background: Black Tea is a widely consumed drink in the world. Evidence suggest Black Tea has stimulatory effect on humans. We investigated the effect of Black Tea on cognition using a cognitive test battery. Methods: Participants (n = 32) were fasted overnight for 10 h and restrained from caffeine and other stimulant drugs for 14 days prior to participation. We randomly assigned participants into either an experimental (n = 16) or a control (n = 16) group. Experimental group consumed 250 ml of Black Tea (BT) while control group was received equal volume of water (W). Participants were tested on the following cognitive tasks: executive function, sustained attention, memory (memory span, immediate, delayed, working memory) and arithmetic calculation task. Conclusions: BT consumption speeded the performance, improved memory, reduced number of errors in the various cognitive tasks. Our results further showed that even in small volume of BT consumption can speed up cognitive processing.

“…Search for the generator of P2 suggested dorsolateral prefrontal cortex as a primary candidate, specifically orbitofrontal cortex (Potts et al, 1996(Potts et al, , 2006Potts and Tucker, 2001;Ruijter et al, 2000). This brain area is associated with cognitive control (Barber and Carter, 2005;MacDonald et al, 2000).…”

“…Most sensitive to task difficulty was the posterior N2b. The N2b component, which has its maximum amplitude at electrode Cz at about 260 ms, was associated with attention to color and target detection effects (Ruijter et al, 2000;Potts and Tucker, 2001). Eimer (1996) examined Fig.…”

Objective: The present study examined oscillatory brain activity of the EEG gamma band and event-related potentials (ERPs) with relation to the difficulty of a visual discrimination task.Methods: Three tasks with identical stimulus material were performed by 9 healthy subjects. The tasks comprised a passive control task, and an easy and a hard visual discrimination task, requiring discrimination of the color of circles. EEG was recorded from 26 electrodes. A wavelet transform based on Morlet wavelets was employed for the analysis of gamma activity.Results: Evoked EEG gamma activity was enhanced by both discrimination tasks as compared to the passive control task. Within the two discrimination tasks, the latency of the evoked gamma peak was delayed for the harder task. Higher amplitudes of the ERP components N170 and P300 were found in both discrimination tasks as compared to the passive task. The N2b, which showed a maximum activation at about 260 ms, was increased in the hard discrimination task as compared to the easy discrimination task.Conclusions: Our results indicate that early evoked gamma activity and N2b are related to the difficulty of visual discrimination processes. A delayed gamma activity in the hard task indicated a longer duration of stimulus processing, whereas the amplitude of the N2b directly indicates the level of task difficulty. q
