According to a new study, conducted by the researchers from Ohio State University, US, coffee is not only can help us more alert and focus but also can enhance interaction within a team. The study was published in the Journal of Psychopharmacology.
For the research, the scientists conducted two related experiments. For the first experiment, seventy-two undergraduate students were recruited. They were randomly split into groups of 5 persons. For the second experiment, the scientists recruited 61 participants.
Having analyzed the received data from both experiments, the researchers found that the volunteers who had drunk regular coffee before participation tended to talk more, but they were also more focused on their given topic of discussion and did not ramble as much as those who had not ingested caffeine.
