Experiments can be run multiple times per day, without data collection becoming impractical. We can study people in environments they do not find intimidating. Data can be collected on larger, more varied, international populations. With high-speed broadband, improved web technologies and smart devices everywhere, studies can now go online without sacrificing too much temporal precision. These studies are still typically conducted on small numbers of people in laboratory environments equipped with dedicated hardware. psychology, neuroscience, linguistics or mental health) use computers to present stimuli and record responses in a precise manner. Many studies in behavioural sciences (e.g. You can contribute by submitting pull requests to the PsychoJS GitHub repository, and discuss issues and current and future features on the Online category of the PsychoPy Forum. You can create online experiments from the PsychoPy Builder, you can find and adapt existing experiments on, or create them from scratch. It is the online counterpart of the PsychoPy Python library. PsychoJS is a JavaScript library that makes it possible to run neuroscience, psychology, and psychophysics experiments in a browser. Many other people have used PsychoPy and Python to display stimuli and record EEG - this task is in no way insurmountable.Home Project Website Forum Github Modules You might be best to describe specific issues and seek help with those. As noted above, the alternatives you list either won't give the level of control you need, or will also require Python for hardware interfacing. I'm not that familiar with SuperLab, but it has been around a long time, and does seem to be focussed on lab equipment use.īut it seems that your issues are more to do with working in parallel with other computer processes rather than PsychoPy per se (which doesn't impose any limitations other than those inherent in Python itself). Paradigm seems to have a nice interface but to add more sophisticated functionality, also uses Python scripting (although seems to still be at version 2.6). OpenSesame is Python (and often PsychoPy) based under the hood. If you are facing difficulties with PsychoPy, which is really just a set of modules with the full power of Python behind it, then you are certainly going to be frustrated with options like PsyToolKit, which, being browser-based, is never going to be able to give you the level of control you need over your system. My biggest issue was with the threading logic, which must, most definetely, use threading events to work propely. I managed to generate two paradigms (P300 and SSVEP) simultaneously while processing signal with no problems. Thoughts on those would be also very welcomed.Īfter finishing my Master Thesis and looking back at this question, I definetely have to share that Psychopy does the job. If you have any resources that could prove me wrong, please feel free to link them too. I tried looking into OpenSesame in the past too, but it seems like it is not possible to acquire signals that easily with it. Some toolkits that show up as alternatives to Psychopy are PsyToolkit, Paradigm and SuperLab 6, but I'm not sure they have the same functionality. I was wondering if anyone knows alternative toolkits, plugins, or libraries that would be suitable for implementing such interfaces (i.e., flashing, sending timestamps, and modifying interface based on classification feedback). I've been trying to use Psychopy toolbox for the interface part, but, unfortunately, it has been such a headache to make it work properly in parallel with the other processes on my current Lab PC that I'm starting to look for substitutes. I'm trying to build a brain-computer interface (BCI) experiment in Python that involves "high frequency" flashing (SSVEP), decision-making stimuli (P300), signal acquisition (EEG, with OpenBCI), and classifiers.
