Dear Cedrus Support,
I generate task by using superlab 4.5 and I use response pad 834 for participant’s response.I use Acqknowledge software (Biopac) for acquisition and analysis.Because of I will study ERPs, so I use Stim tracker for generate event marker. I connect StimTracker to Biopac via STP1100 c.
I perform all of these by using Cedrus & Biopac Guide and Manual but Superlab can not talk to Stimtracker and disappear marker in Acqknowledge software. I have already installed USB driver.
I need an event marker, that sends pulse to EEG recording device in difference condition (stimulus onset, participant’response and feedback) simutaneously.
Detail (what I want experiment to do)
- Display of four reference cards on the upper third of computer screen, plus one response card occupying center on the lower third of the screen.
- Participant will press response pad (RS834) for sorting.
- Auditory feedback is delivered 1600 ms after the response.
- Next trial ( 2 -3 sec after feedback)
I created an event “Digital Output”, set it to “Generate a pulse” with a duration of 500 milliseconds, Inter-pulse interval 200 milliseconds and set repeat pulse to 1. Turn on all checkboxes labeied EM0 through EM7. I created event “Digital Output” 3 event for stimus onset, participant’s response and feedback.
A complete task consists of two blocks with 18 series of 7 trial each) Semi random.
I am unsure whether I have created the experiment correctly and I am not sure If that is due to a mistake on my part or not.
