All releases of PEBL
Release Notes: Internationalization and handling of graphics were improved. Much more was done.
Release Notes: Highlights of the new release include better handling of international fonts and a survey script that allows you to collect survey responses by editing a spreadsheet file.
Release Notes: This version offers many fixes and improvements, including additional drawing functions, ten new tests in the test battery, and better robustness on Windows.
Release Notes: This version sports better handling of international character encodings (if you save in UTF-8), a number of bugfixes, some new functions related to statistical analysis, updates to the test battery, including new tests, a Vigilance task, the Hungry Donkey Task (a risk/gambling task for children), a version of Sperling's partial report procedure thought to be able to detect Alzheimer's at an early stage, and a skeletal tower of London.
Release Notes: This version includes a number of useful functions, improved documentation, new fonts, and the ability to do simple TCP/IP networking. Three supplementary packages are now available: the PEBL Image Archive, the PEBL sound archive, and the PEBL Test Battery. The Test battery represents an initial attempt to cover a number of standard tasks used in psychological and neuropsych testing, including versions of the Wisconsin Card Sort, Iowa Gambling task, Test of Variables of Attention, and a number of others.
Release Notes: While the previous release focused on stability, this release brings some substantial changes to the underlying object management system, so a few bugs may have crept in undetected. Major user-visible changes include the ability to create simple shape objects (like Circle(), Ellipse(), etc.), the ability to access object properties directly with a variable.property syntax, and a few new statistical functions. There is a nicely improved 100-page manual in PDF and HTML format, and a wiki is available on the Web site for help and tips.
Release Notes: This release focuses on memory management and other infrastructure. There are few user-visible changes, but there are substantial beneath-the-hood fixes thanks to memory profiling tools like memprof and valgrind. This is the first official release of PEBL for OS X, making it possible to write a single experiment that can be run on Linux, Mac, or Windows.
Release Notes: This release includes a bunch of new functions and some ready-to-run experiments. The display options may now be set as arguments, enabling different screen sizes, full-screen or windowed operation, and specifying the SDL driver you want to use. There is also an experimental automatic setup utility for Windows that puts PEBL into C:\Program Files\PEBL, creates a PEBL experiment folder in My Documents, and creates launchers that run these nicely.
