A Comprehensive Tutorial on the Python Framework - oTree

Running online experiments effectively can often pose unique challenges, particularly when it comes to the intricacies of behavioral and cognitive tasks. That's where tools like oTree come in - a framework that can facilitate and streamline this process for researchers.

Step-by-Step Guide to Setting Up an Experiment Using oTree

While boasting ample features for psychological research, oTree also presents a steep learning curve. Let's simplify that with a step-by-step approach to setting up an experiment.

  • Step 1: Begin by installing oTree using Python's package manager: pip install otree
  • Step 2: Afterwards, initiate a new project with the command: otree startproject ProjectName
  • Step 3: Navigate to your new project folder and start a new app: cd ProjectName, then otree startapp AppName
  • Step 4: You'll see several Python files generated - models.py, pages.py, and so on. Use these files to shape your cognitive experiments as desired.

Remember to review the official oTree documentation for deeper insight and guidance on utilizing the framework’s extensive capabilities.

Next Steps to Conducting Online Experiments

Once your experiment is set up, it's important to test it in a safe environment. Running a local server (otree devserver) will enable you to debug before going live. Upon ensuring everything works perfectly, deploy your experiment using preferred hosting services like Heroku or AWS.

Experimenting with oTree

Although daunting initially, oTree is a powerful tool for creating and running cognitive tasks online. It combines the flexibility of Python with built-in capabilities for behavioral experiments. Moreover, paired with jsPsych for web specific tasks, it provides a full toolkit for remote studies. For more experiment design tools, be sure to explore Cognition.

Remember, the key to successful online experiments is thorough planning, accurate implementation, and meticulous testing. So, go ahead, start creating, and good luck with your psychological research!
