This is the main website for the PEBL
programming language and execution environment.
PEBL is:
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. NEWS [2019-03] PEBL Version 2.1

[2017-04] PEBL Version 2.0 Beta 4
[2016-09] PEBL Version 2.0 Beta 3 [Update]. New beta 3 is now available on all platforms. This should fix problem on OSX. The second beta release of PEBL 2.0 is here. Along with updates and fixes in 2.0beta1, this includes a new translation scheme for the test battery. Now, to translate a test, you simply need to set your 2-letter language code in the launcher, select the test in the battery, and tlick the 'translate test' button. This will let you translate each instruction and label needed for the test. If no major problems are reported, this release will become PEBL 2.0. PEBL 2.0 beta3 is available both stand-alone and as an installable package for windows. Here is a video describing installation and some basic features of PEBL 2.0: [2016-09] PEBL Version 2.0 Beta After two years, version 2.0 of PEBL is in Beta release. This release involves a transition to hardware-accelerated graphics, and many updates and changes. The beta release is available on OSX as a package and on windows as a standalone executable (it does not need to be installed--just run it from your desktop). The final version of 2.0 will have updated documentation and improvements to translations and individual tests that don't yet appear in the beta release. I'd recommend using 0.14 (which will turn into 1.0) unless you are having specific problems with that release (such as most OSX users) If you find any problems with 2.0 beta 1, please send feedback on the forum or email. [2014-06] PEBL Version 0.14 The latest release of PEBL, version 0.14, is now available. As part of Version 0.14, we offer many new features including custom object support that allows for better object-oriented UI. As part of this, I have completely revamped the launcher to make it more polished and easier to use. One important addition this adds is the ability to set and change running parameters of tests in the battery. As a consequence, every single test battery test has been modified, and we have added at least ten new tests, bringing the total to around 100. Complete release notes are available here. Highlights to the test battery include new O-span, Sym-span, and reading-span tasks contributed by David Hegarty, an improved Iowa task contributed by Peter Bull, new code to do PAR-type scoring on the Wisconsin (Berg) card-sorting test, a dual n-back task, a Luck-and-vogel style change detection task, several verbal and memory tasks (DRM; probe-digit; ebbinghaus, brown-peterson, recognition memory, remote association task, paired-associates learning), some nice new scales (Berlin numeracy, handedness, big-five personality), Esposito's Bivalent Shape Task (a nonverbal stroop analog), and really to many improvements to list here. Also, we have started a crowd-funding campaign to help support future development of PEBL. When you launch the PEBL launcher, you will be given the option to donate to the project. Donors will be given a special access password allowing them immediate access to the launcher, and our eternal gratitude. In the coming weeks, I'll be making several getting started videos available via the PEBL Blog, to help new users. [2012-12]PEBL Version 0.13 and Test Battery 0.7 The latest release of PEBL, version 0.13, is now available. Along with a lot of little fixes and updates, there are two major new functionalities that will impact users. First, the underlying list structure used by PEBL is now a vector, allowing constant-time access of arbitrary elements. This transition has some pretty nice benefits for accessing elements efficiently, with very little drawback for the typical uses of PEBL. Next, we now support playback of movies and audio-media files via the waave library, which itself uses the ffmpeg library. Smaller changes include improved functions for handling screen size, network communication, improvements to the launcher, a change in how AddObject works when the object already has een added to a window, In the battery, I've changed every test so that they save data in .csv format for easier analysis, and they should also save in a data\ subdirectory. I've added several new tests to the test battery, including Salthouse's Connections task, a few memory tasks (one patterned on Ebbinghaus, the so-called Brown-Peterson test, the Dual N-Back test, Sternberg's memory scanning task, and others. Also, there is improved support for multi-user systems. Now, PEBL will launch the first time and copy files to your Documents folder. [2012-01-02]PEBL Version 0.12 and Test Battery 0.7 The latest public release of PEBL, version 0.12, brings with it a lot of new features and capabilities. Highlights include support for a number of hardware interface devices, a new launcher, over 250 total functions, audio input, and a number of new tests in the PEBL Test Battery, and many bug fixes and improvements. Some of the biggest and most visible changes include:
[2010-07-23]PEBL Version 0.11 and Test Battery 0.6 I've released the newest version of PEBL, version 0.11, and a new version of the PEBL test battery, called 0.6. Version 0.11 contains a lot of under-the-hood fixes to memory management. Previously, PEBL had a number of memory leaks which could end up crashing the system if it ran for too long. Most (all?) are now gone, which should improve performance. Also, a new widget called a 'canvas' is available, which lets you create more complex widgets, do pixel-drawing and other cool stuff. Using it sometimes can (reliably) cause crashes the program on windows that I have not yet tracked down, so think of it as fairly experimental right now. Also, I've made a lot of progress toward enabling internationalized experiments. I've also now have translations of the BCST and Bechara Gambling task into polish, chinese, and korean, and translation of TOL into Spanish (and Portuguese soon). Those of you who want translated versions of these tasks can now do translations of text strings and run by specifying a two-character country code in the launcher. This comes at a slight cost--korean and chinese fonts are now included, making the download about 50% larger than last time. Also, I've moved to a default font which handles western characters much better, so accents on most european languages should be handled seamlessly. Also, along with a windows installer, I'm releasing a stand-alone version for windows (in case you don't want to install it), and a .deb suitable for some Ubuntu linux systems. I once again have PEBL running on OSX, and will work toward a distributable version of PEBL 0.11 on OSX in the near future. [2010-02-09]PEBL Test Battery Version 0.5
