Trust Game for Center for Conflict and Cooperation

This repository hosts a behavioral trust game experiment designed for the Center for Conflict and Cooperation. The experiment is implemented as a web-based application that can be accessed directly through GitHub Pages.

Experiment Overview

The Trust Game is a classic behavioral economics experiment that measures trust and reciprocity between participants. In this version:

• Participants start each round with $10
• They can choose to send $0, $5, or $10 to a simulated partner
• Any amount sent is tripled before the partner receives it
• The partner (simulated with different personalities) sends some amount back
• Participants play 5 rounds with different partners

Features

• Web-based: Runs entirely in the browser, no installation required
• Data Collection: Automatically downloads participant data as JSON files
• Responsive Design: Works on desktop and mobile devices
• Progress Tracking: Shows progress through the 5 rounds
• Demographic Collection: Collects basic participant information
• Results Summary: Provides detailed feedback and analysis

Data Collection

• Each participant receives a unique ID
• Automatic Repository Submission: Data is automatically saved to the repository's /data folder
• Fallback Options: Local download as JSON/CSV files if automatic submission fails
• Manual Submission: Clear instructions provided for manual data submission when needed
• Contains demographics, trial-by-trial decisions, and summary statistics
• No server required for basic functionality - all data processing happens client-side

Data Submission Setup

For automatic data submission to work, repository maintainers need to configure a GitHub token. See DATA_SUBMISSION_SETUP.md for detailed setup instructions.

Quick Setup for Repository Owners:

1. Create a GitHub Personal Access Token with repo and workflow permissions
2. Add it as a repository secret named GITHUB_TOKEN
3. Data will be automatically saved to the /data folder when participants complete the experiment

If automatic submission is not set up, participants will receive clear instructions for manual data submission.
