I develop software for experimental psychology . My main project is JASMIN; a framework for efficiently designing and deploying a limited set of reaction time tasks. The framework is configurable via forms; compatible with desktops, laptops, smartphones, and tablets; and is multi-lingual. Reaction time tasks realized via JASMIN can be integrated in various other systems, such as LOTUS, and have been deployed in studies by researchers from the UvA, from other European universities, and from private companies. In a joint research and software development project, the framwork will be further developed in order to support a wider range of reaction time tasks, while simultaneously studying the validity of results acquired via JASMIN.
