I need a speech and ppt within 10-15 minutes. My request is to focus on a psychological experiment. Describe the experimental background of the experiment, the experimental results, why the experiment is controversial, and what the final result is. The controversy can be about the accuracy of the experimental results, the operation of the experimental process, etc. There can be a part, but please don’t focus on experimental moral disputes. Thank you
