== **PEBL: The Psychology Experiment Building Language** == **Description:** PEBL (Psychology Experiment Building Language) is a new programming language developed especially for building psychology experiments involving human participants interacting with a computer. It is free psychology software for creating experiments which allows you to design your own experiments or use ready-made ones and lets you exchange experiments. Development and design of PEBL began in 2002. An initial limited release of PEBL 0.1 was made in 2003, with the first public release to the Sourceforge.net servers in January 2004. PEBL is designed to be easily used on multiple computing platforms. Its current implementation uses the SDL as its implementation platform, which is also a cross-platform library that compiles natively under Win32, Linux, and Macintosh Operating Systems. PEBL is programmed primarily in C++, but also uses flex and bison to handle parsing. PEBL is designed to be an open system, and is licensedunder the GNU Public License 2.0. This allows users to freelyinstall the software on as many computers as they wish, to sharetheir experiments with others without worrying about licenses,to distribute working experiments to other researchers or remote subjects without requiring special hardware locks, and to examineand improve the system itself when it does not suit one’s needs. **URL:** ​ [1] http://pebl.sourceforge.net/ [2] http://obereed.net/docs/MuellerSCIP2004.pdf [3] https://sourceforge.net/projects/pebl/ [4] https://www.researchgate.net/publication/258853238_The_psychology_experiment_building_language_PEBL_and_PEBL_test_battery [5] http://www.superiorideas.org/projects/open-source-psychology-software == **Project Anatomy**== **Community** **Leadership** **Forking** **Communication** **Roadmaps** **Releases** **Repositories** **Packaging** **Upstream/downstream** **Version Control** **Trackers** **Project Evaluation** == **Fieldtrips**== **Github:** **Openhub:** **Source Forge:** == **Evaluation** == **Licensing** GNU Public License 2.0 **Language** **Activity** **Number of contributors** **Size** **Issue tracker** **New contributor** **Community norms** **User base**
