yc c on 07 Jun 10PXLab 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.
