The PEBL Psychological Test Battery

About the Battery

This site is for a battery of psychological tests implemented in PEBL and distributed (and redistributeable) freely. They are designed to be easily used on multiple computing platforms, running natively under Win32, Linux, and Macintosh OSX Operating Systems. The tests are designed to use only keyboard input and only visual stimuli, to enable easy use on laptops in diverse environments.

The current version of the battery 0.2. It is designed to work with PEBL version 0.08 which was released in late summer 2007. The battery is distributed with version 0.08, (it can be found in Program Files\pebl\battery) but it is also available on its own so that updates to the battery can be made without impacting the main PEBL package.

These tests are designed to closely resemble many commonly-used psychological tests, some of which are only available on limited computing platforms or cost hundreds of dollars. Each experiment saves the complete data set for later analysis, and computes basic analyses that it writes in report format. Details about the tests are found in the battery.txt file that is distributed with the library.
