The experiment was conducted to test the effects of caffeine on memory. The researchers recruited 100 participants aged between 18 and 30. The participants were randomly divided into two groups: the experimental group and the control group.
The experimental group was given a 200mg caffeine pill to take, while the control group was given a placebo. Both groups were instructed to take their respective pills an hour before the memory test.
The memory test consisted of showing the participants a list of 20 words for 3 minutes. After the time was up, the participants were given another task to complete for 10 minutes to distract them. After the 10 minutes had passed, the participants were asked to recall as many words from the list as they could remember.
The results of the experiment showed that the participants in the experimental group, who had taken the caffeine pill, recalled an average of 12 words from the list. On the other hand, the participants in the control group, who had taken the placebo, recalled an average of 8 words from the list.
The researchers concluded that the participants who had taken the caffeine pill showed significantly better memory recall compared to those who had taken the placebo. This suggests that caffeine has a positive effect on memory.
However, the researchers also noted that further studies are needed to explore the long-term effects of caffeine on memory. It is also important to consider individual differences in caffeine sensitivity and metabolism, as these factors can influence the results.
In conclusion, the experiment demonstrated that caffeine has a positive impact on memory recall in the short term. Future research should delve into the potential long-term effects and the individual differences in caffeine response.
