What is PXLab?
PXLab is a collection of Java classes and applications for running
psychological experiments. The PXLab system allows interactive design
of a wide range of experiments from all areas of psychological
research. It includes a run time control system which runs experiments
under highly optimized timing constraints.
PXLab's major features include:
- Complete procedural control for sessions, blocks, and trials,
- display composition by combining elementary display objects,
- timing groups of display objects,
- more than 100 elementary display objects: text, geometric objects, images,
gratings, sound, movies, and many more,
- conditional display execution,
- response collection from keyboard, mouse, external devices, and sound
channels,
- precise timing with optimized use of accelerated video memory,
- automatic time control and report of all timing properties,
- vertical retrace synchronization with native code library under Windows,
- color control by CIE chromaticity coordinates using built in gamma correction,
- all display object properties controlled by experimental parameters,
- experiments can run as local applications or as HTML-embedded applets using the same
design file,
- same program does data collection in the laboratory and on the internet
- extensible by implementing new display objects in Java code
- uses ASCII design files,
- tools for design file editing, command line experiments, and color calibration,
- special features for class room demonstrations and laboratory courses.
PXLab is available under an Open Source License. If you are interested in
