Implement a short trial loop and confirm every output column before extending the study. Run timing checks on the computer and devices participants will use, and pilot instructions with someone unfamiliar with the task. Keep the experiment version and analysis script linked so changes in stimuli or response coding remain traceable.
This is best suited to researchers building behavioral experiments. Before committing a larger project, account for these trade-offs: timing needs validation on study hardware; online hosting can require paid services.
