I will be conducting an experiment measuring GSR while simultaneously presenting stimuli through the software package PsychoPy. Rather than reinvent the wheel, I thought I'd ask whether anyone has done this before and whether they have some advice/resources/tips or open-source examples of past experiments. Thanks in advance for any useful answers.
Hi Sam,
So I haven't actually used psychopy with biopac, but based on my experience getting psychopy set-up with eyetracking and a quick google search I'd suggest going to this link: https://www.kent.ac.uk/psychology/technical/experiments.html and downloading the 'parallel port fire' file, which should give you a good starting point. (Basically, it provides you with a psychopy exp that has the framework to send triggers to acqknowledge.) I hope that's somewhat helpful - good luck!
Hi Sam,
While sending the synchronization triggers to Biopac can be done by most stimulus presentation software, you might be also interested in controlling your stimuli by some characteristics of a real-time GSR signal. In this case you can look at our software, EventIDE (www.okazolab.com), which would allow you to build various neuro-feedback paradigms with Biopac, e.g. present a stimulus upon detection of a specific signal pattern online. You can see one of our demos here: https://www.youtube.com/watch?v=8IobJs0ZTaQ
