Group: Awaiting Activation Posts: 6, Visits: 38	Dear all, Is itpossible to link inquisit 4 to physiology? And is this difficult to learn forsomeone, who has not worked on programming with physiology? (I heard it hassomething to do with programming some triggers) We areusing four different tasks: Scrambled sentence task, priming paradigm, singletarget IAT and an interpretation task, where participants have to rate themeaning of ambiguous sentences. The tasks are almost programmed. Thephysiology we will measure is: Respiration, heart rate, skin conductance. In case itis too difficult, is there a possibility to commission the programming of thetriggers? What would be the costs? Thank youand best wishes!

You can send TTL signals to external equipment via a system's parallel or serial port, as well as via a Cedrus StimTracker. What signals to send would depend on the particular equipment you use, i.e., which signals it expects (if any in particular); the equipment's vendor documentation should provide the necessary details. The Inquisit documentation topics you'll want to consult are https://www.millisecond.com/support/docs/v4/html/howto/howtoportmonitor.htm https://www.millisecond.com/support/docs/v4/html/howto/howtosendport.htm https://www.millisecond.com/support/docs/v4/html/language/attributes/port.htm https://www.millisecond.com/support/docs/v4/html/howto/cedrusstimtracker.htm You can find various scripts in the library to look at as concrete examples, e.g. the Auditory Oddball Task: https://www.millisecond.com/download/library/Oddball/ <port> elements work like any other stimulus elements in Inquisit. I.e., you "display" them via a <trial>'s /stimulustimes or -frames just like you would a <text> or <picture> element. For example <trial mytrial> / stimulustimes = [0=fixation; 500=mytext, mytrigger] ... </trial> with <port mytrigger> / port = lpt1 / subport = data / items = ("00000001") </port> would send "1" over the system's 1st parallel port (LPT1) coinciding with the display of <text mytext>. You can also commission Millisecond to write and/or adapt existing scripts for you. You would still have to provide the necessary information (i.e., what devices are you using, how do they interface, what signals do they expect, when / what signals do you wish to send, etc.), of course. You can contact sales@millisecond.com and they'll be able to give you a cost estimate. Hope this helps.
