<prompt> Rala teko ea ho fuputsa litlamorao tsa caffeine tšebetsong ea kelello.nan  <response>: Instruction in English: Design an experiment to investigate the effects of caffeine on cognitive performance. . Response in English: Objective: To investigate the effects of caffeine on cognitive performance in healthy adults.Hypothesis: Consuming caffeine will enhance cognitive performance in healthy adults.Methodology: 1. Design a randomized controlled trial with a sample size of 100 healthy adults.2. Divide the participants into two groups: caffeine group and placebo group.3. The caffeine group will receive an oral dose of 200mg of caffeine approximately the amount in two cups of coffee while the placebo group will receive an identical-looking sugar pill.4. Both groups will perform the same battery of cognitive tests measuring reaction time, attention, memory, and reasoning. These tests will be administered at baseline, 30 minutes, 60 minutes, and 120 minutes after the caffeine or placebo intake.5. Data will be collected and analyzed using statistical tests to compare the performance of the caffeine group to the placebo group.6. Possible confounding variables, such as sleep quality, age, and gender will be controlled for.Expected results: We expect to find improved cognitive performance in the caffeine group compared to the placebo group. Specifically, reaction time, attention, memory, and reasoning may improve as a result of caffeine intake.Conclusion: If the results support our hypothesis, we could conclude that caffeine enhances cognitive performance in healthy adults. Further research could investigate the ideal dose, duration and frequency of caffeine intake to achieve optimal cognitive performance. .
