PscyhoPy as alternative to E-Prime?

) as an alternative to E-Prime, or just have any thoughts on this?

We've found that students have had some difficulty with it. The "Builder" is not very sophisticated (compared to E-Prime) and there
is still a lot that needs to be done in script which most of our students have a hard time dealing with. And like most scripting based systems it works great if you have a small stimuli set and a simple design but once you start building experiments with multiple blocks of stimuli and more complex designs (e.g. training studies) the scripts just become massive and difficult to change. We've stuck with E-Prime and some students have started using another program called Paradigm which seems to be a nice compromise between the two (because it uses Python as a built-in scripting language) and has a better experiment designer.

it would be well suited to EEG. It's a hard to find website unfortunately... here's the link: http://www.paradigmexperiments.com

Hi,
My 2p: PsychoPy is extremely popular around Nottingham, but then again, the main developer of the software, Jonathan Peirce, does work there (at Nottingham Uni, School of Psychology, where I did a postdoc, not Trent, but I suppose the influence spreads). He is quite approachable, so if you want to check it out, David, I think you’d best either ask him (or the community) or install the software yourself, because I can only give you my few impressions:
* It is pretty good, and they are making the visual drag-and-drop interface better. The coder is aware of E-Prime and how difficult students can find it, and has made sure that a lot of it is quite intuitive: loops (re-running the same trial procedure), for example, are displayed as loops (if I remember correctly).
* Somebody mentioned python and paradigm: psychopy is built on top of psychopy and the UI just generates python code. So yes, you can do “scripting” (urgh), in python. Personally I really dislike Python and felt this was the most annoying problem of PsychoPy. I am quite certain this is just me being lazy: I’d sooner learn more C, C++, C#, basic, java, etc, than learn yet another language… Finnish is difficult enough for now.
* PsychoPy has really cool stimulus features that are both part of Python (better drawing classes than ebasic) and possibly because of Jonathan’s interests in psychophysics. Want to display a gabor stimulus in a fine lines of code? You can! Want to make it rotate? Right-on! …okay, I admit I seldom want to do that sort of thing, but I’ve come to appreciate that some people like it.
* I think E-Prime really shines in doing RT experiments, priming experiments with fantastically accurate timing. PST seems also really fond of that sort of thing, so I’m suspecting PsychoPy isn’t as well-tested. You can and should test that, though J
Hope that helps!

Hi,
I went to an introductory course for this at Nottingham Trent a while ago. It is quite similar to E-prime in a lot of ways, but appears to be much easier to use; simply take a while for you to find your way around. I have only used it for very basic experiments, but from the training session it is very user friendly, with the bonus of being free.
Not sure if this has helped any.

Hi,
Given them both having Python as built-in scripting language, these classes should theoretically be available for both. I remember physiological experiments have been done with psychopy as well, in any case. Not here to defend an old colleague’s software – I’ve always been The Go-To E-Prime person J. Then again, I bet so is David: what’s happening, getting finally fed up with E-Prime?
Cheers,
Michiel

I believe they have an add-on package that allows you to send triggers to EEG systems. I know we've had no problems with timing so I think
