z-Tree unleashed

z-Tree unleashed enables remote execution of z-Tree computerized behavioral experiments over the Internet to collect controlled behavioral data for experimental economics and behavioral sciences.

Key Features:

• Client-integrating architecture: Enables z-Tree experiments to run across distributed clients over the Internet.
• Browser-based participant access: Participants connect using standard web browsers to participate in experiments.
• Remote experiment administration: Supports hosting and administration of experiments from remote locations.
• Open-source foundation: Built on free and open-source software except for the core z-Tree executable.
• VPN security and routing: Integrates virtual private networks (VPNs) to allow servers to operate behind routers and secure communication channels.

Scientific Applications:

• Experimental economics: Enables remote collection of interaction and decision-making data for controlled economic experiments.
• Behavioral sciences: Supports behavioral experiments with distributed participants to increase sample diversity and generalizability.
• Distributed controlled experimental designs: Allows implementation of various experimental designs that require controlled environments and precise data collection across locations.

Methodology:

Set up a server environment to host experiments and configure VPN capabilities to establish secure communication channels between participants and servers.
