Gitlab Repository Matrix

Description

The Gitlab Repository Matrix contains matlab files for the Matrix program. This program can present several sentences of five words each to a subject with a headset and keep score of the subject recalling the correct words. The program can mix sentences with noise and also vocode the spoken words and/or noise. The program can present Dutch and German sentences. The program can also present objects on a second screen to the subject. It can use an eyetracker to record the pupil size of the subject and it can use an event recorder to synchronize the sound-, screen- and eyetracker-data.

How to install the Matrix program

• Copy the repository to your computer in a directory
• Open in matlab
• Make a directory 'C:\DATA\<your initials>\matrixtest\Results
• Make a directory 'C:\DATA\<your initials>\matrixtest\Sounds
• Copy the 'Sounds\NL' and/or 'Sounds\DE' or directory from \\mbcogro-srv.science.ru.nl\install\matrixtest
• Open the file 'matrix_main.ini'
• In the ini-file select the language under [global]
• In the ini-file select the hardware you will use under [hardware]
• You can customize the tasklist using the <loadfromfile> option under [tasklist] and specify the tasklist in a file named <Tasklist.ini>
• In order to customize the trial you can edit the file <..\matrix\trialPlayer\matrixTrialPlayerClass.m>
