PSYTASK is a program for preparation and carrying out psychophysiology investigations.

PSYTASK's main features are:

1. Visual (on the monitor screen) and auditory (using sound card and speakers) stimuli presentation.

2. Reaction time measurement. To measure the reaction time keyboard and mouse can be used.

3. PSYTASK is working together with “Mitsar” digital EEG amplifier and WinEEG advanced version software it provides a synchronous stimuli presentation with EEG acquisition. In this case two computers connected via COM ports are used.

PSYTASK program works on the first computer and WinEEG program works on the second computer. WinEEG program sends synchronization codes to PSYTASK program to control its work and provides a synchronous stimuli presentation with EEG acquisition. The recoded data can be used to calculate and analyze event related potentials (ERP) and/or event related desynchronization (ERD).

4. PSYTASK program can send synchronization codes to another program via COM port. This feature provides a possibility to carry out ERP studies using other amplifiers and another program that is able to detect synchronization codes.

5. PSYTASK program has a user friendly interface that provides the possibility to design psychophsiological tasks.

6. PSYTASK program measures the reaction time and task performance parameters (omission and commission errors) and saves them to build-in database for the future analysis and final report preparation.
