For the study, a total of 90 university students were recruited for two experiments. As part of the first experiment, 50 participants were divided into two groups that either drank one cup of black tea or one cup of water three minutes before the experiment began. All of the students were tasked with building an appealing block design for a fictional toy factory within a 10-minute time frame. The researchers enlisted an additional 10 university students to judge the block designs based on an 11-point scale for grandness, unification, aesthetic appeal, and innovativeness. The tea drinkers group scored 6.54 points while the water drinkers group scored 6.03 points
As part of the second experiment, 40 participants underwent the same procedures as the first. They were separated into two groups and made to drink either black tea or water. However, one participant from the water drinkers group wasn't given anything to drink. For this portion of the study, the researchers asked the students to name a newly opened ramen shop. They had 20 minutes to come up with up as many “cool and attractive” names as possible. Again, 10 more university students were called in to judge the names based on playfulness and innovativeness. Just like in the first experiment, the tea drinkers scored higher at 4.11 against the 3.78 score of the water drinkers group.
“This work contributes to understanding the function of tea on creativity and offers a new way to investigate the relationship between food and beverage consumption and the improvement of human cognition,” wrote the researchers.

They added: “Two biological ingredients, caffeine and theanine, have beneficial effects on attention, which is an indispensable part of cognitive function. But the amount of tea ingredients our participants absorbed was relatively small. Also, theanine facilitates long-term sustained attentional processing rather than short-term moment-to-moment attentional processing”
Despite this, the researchers believe that the efficacy of tea in the short-term is due to its ability to boost mood.
