Interfacing with iWorx?

Group: Forum Members Posts: 8, Visits: 55	I was wondering if anyone has managed to interface Inquisit with iWorx in order to measure autonomic response? Basically, I need to be able to see if the autonomic response (Heart rate & skin response) are increasing in line with a decrease in success on the SART (and vice versa) I'm running via Inquisit. I have both programs on the same computer, though I can run them on 2 different computers if need be, I have the cables and software to do so. I'm just hoping someone has had experience with this and might have some pointers? Thank you in advance.

I.e., you can have Inquisit send markers to your device that signify certain events (e.g. the start of a trial, the display of a stimulus, the occurrence of a response, etc.). Your hard-/software would record those markers along with the acquired physio data, thus allowing you to sync the two. Relevant documentation topics would be: "How to Present TTL Signals Through the Parallel Port" https://www.millisecond.com/support/docs/v4/html/howto/howtosendport.htm "How to Use the Parallel Port Monitor Tool" https://www.millisecond.com/support/docs/v4/html/howto/howtoportmonitor.htm The language reference for the <port> element http://www.millisecond.com/support/docs/v4/html/language/elements/port.htm As an elaborate example, you can refer to the "Auditory Oddball Task" script https://www.millisecond.com/download/library/oddball/ The documentation for your iWorx gear should have all the necessary information re. the supported input methods as well as which signals it expects. It would seem that at least serial interfaces are supported (cf. https://www.iworx.com/research/software/iworxserialinterface/ ). Edited 9 Years Ago by Dave
