Hi everyone
I am a PhD student, new to inquisit lab and could use some advice. I am just about to try and set up my pilot study and wondered if there was an existing script that would work.
My experiment is showing participants affective images while recording their brain signals with an EEG cap. What I need Inquisit to do is show the images (from the IAPS dataset)
at a set interval, maybe 10 seconds for each image. Is their a script that could do this? Or is it easy to write this kind of script? Any advice would be great, thanks in advance.

Is there any reason to go for Inquisit 4? I was about to buy Inquisit 5 but as it's still offering 4 I wondered if there was any benefit to it. Thanks

Thanks I don't see any benefit to staying with Inquisit 4 at this point. Inquisit 5 is definitely more flexible and works on a greater number of systems (especially if you're planning to run things on the web at some point). On the other hand, you may not need the additional features Inquisit 5 offers over Inquisit 4 for your particular study or studies. If you're working in a lab environment / offline setting, already have Inquisit 4 available and/or feel comfortable with Inquisit 4, there is no urgent reason to switch.

Is there a way to increment the time results to show the time that each image was shown? For example, The results show 19:33:41 19:33:41 19:33:41 Where I would like something like 19:33:41 19:33:46 19:33:51 I have attached a screenshot of the results. Really sorry to be pain. Thanks again

Thanks again To do that you should add a <data> element to your script and then log the script.elapsedtime and/or the picture.mypicture.timestamp property, i.e. something like this: <data> / columns = (date time subject group blocknum blockcode trialnum trialcode trialduration response latency correct stimulusitem stimulusnumber trial.mytrial.timestamp picture.mypicture.timestamp script.elapsedtime) </data> the timestamp would reflect milliseconds elapsed relative to the start of script execution, not absolute time. You can, of course, derive absolute time (approximately) by calculating it from the timestamps and the start time recorded in the "time" column. NB: If your eventual aim is to synchronize measurements with your EEG, sending a marker to the EEG via the parallel or serial <port> and having the EEG record that marker is the vastly preferable option. To to this, you would set up a <port> element in your script and "display" that <port> stimulus along with your stimulus. See the following scripts as examples https://www.millisecond.com/download/library/oddball/https://www.millisecond.com/download/library/neuroscan/as well as the documentation for the <port> element: https://www.millisecond.com/support/docs/v5/html/language/elements/port.htmhttps://www.millisecond.com/support/docs/v5/html/howto/howtosendport.htmhttps://www.millisecond.com/support/docs/v5/html/howto/howtoportmonitor.htm
