The project presents a bunch of prototypical web applications for behaviorial or psycological online experiments, surveys or tests. The apps are developed using oTree framework and it's new (upcoming) extension oTree-front (shipped in this repository)
The apps implement some basic functionality and intentionally designed to be adjustable for some futher requirements. They may be useful in your research projects as a starting point of your app.
The repository also contains bunch of snippets (python utilities, javascripts, styles) that can be reused in any other project unrelated to the apps.
See USAGE for guides how to use the apps or snippets in your project.
- Main pages of the apps are implemented in a dynamic manner for real-time interaction with low latency. (Contrary to traditional form-based approach that require full page reload).
- Most of the apps run series of trials consisting of some task and expecting some response.
- Responses of participants are immediately communicated and saved on server via live channel.
- All the data for each trial is saved and available in 'custom export' section.
- Where appropriate, pages measure response time with high precision (below 15ms), not affected by network latency.
- The pages are designed in smooth animated styles, reducing visual disturbances.
- The pages do not reveal correct or best answers, all evaluation of responses is performed on server side. That reduces possibility of cheating via inspecting page scripts and content.
