A declarative language in python for creating jsPsych experiments

SweetBean

A declarative programming language built in Python, designed for the synthesis of behavioral experiments. It allows researchers to specify experiments once and seamlessly compile them into a jsPsych experiment for conducting studies with human participants or text-based simulations with synthetic participants using large-language models.

Features

• Declarative language: Specify experiments once and compile them into a jsPsych experiment for conducting studies with human participants or text-based simulations with synthetic participants using large-language models.
• Python-based: SweetBean is built in Python, making it accessible and easy to use for researchers and educators.

Integrate with other packages

This package seamlessly integrates with other packages aimed at running online behavioral experiments:

• AutoRA: For closed loop research, automatic experiment deployment, participant recruitment, and data collection.
• SweetPea: For experimental design.

But it can also be used as a standalone product.

Installation

The package is available on PyPI and can be installed via pip:

pip install sweetbean
