Hello everyone! I have a question regarding a regression model i have to set up for a hypothetical economic experiment we have to conduct for a universitycourse! My experiment has three priming-treatments: control-, Masculine-, feminine-treatment and four types of participants: Hetero men, and women; homosexual men, and women. Each group of participants will have the same amount of people per treatment.

After the priming-treatment each participant will go through a 3-stage task (time-table of the experiment is also provided in the picture "timetable"): The participants have to make an easy, real-effort task where performance should not be different amongst the groups. They play this task for 2 rounds (first one under piece-rate and second one as a tournament, where only the winner gets a payout) different payment schemes. Then have to decide which payment scheme they want to take in round 3. The goal of the experiment is to see if one or both of the treatments (F- or M-Treatment) influence the outcome of the decisions in round 3 realtive to the control group. After these rounds, the participants will fill out a survey and a test to determine a masculinity-feminity-scale.
