INSTALLATION: To run this test, you must first install PEBL on your computer. Then, place this file and related media files in a subdirectory of the PEBL experiment directory (e.g., Documents\pebl-exp-0.14) Finally, run the PEBL launcher and navigate to this file in order to run the test. Data will be saved in the data\ sub-directory of the folder this file was saved in, in a file named BST-XXX.csv, where XXX is the participant code entered in the PEBL Launcher.
HELP: For help installing, running, or interpreting data from this test, please email the pebl-list: pebl-list@lists.sourceforge.net
MODIFYING: A number of options exist for modifying the program. To do so, open the BST.pbl file in a text editor such as notepad++. Editable parameters are near the top of the program, and include:
gUseRandom <- 0 ##set to 1 to make each test different gResponseOffset <- 100 ##Pixels from center line that the responses are placed gResponseY <- gVideoHeight-150 ##Height of responses. gResponseTimeLimit <- 3000 ##Timeout in ms. gUseVisualFeedback <- 0 ##Give visual feedback of 'correct' and 'incorrect' gUseAudioFeedbackAlways <- 0 gUseAudioFeedbackPractice <- 1 numTrials <- 20 ##How many trials per block? gUseMouse <- 1 ##Use mouse/touch input.
