PostDoc (Psychology) at the University of Freiburg, Germany.

My primary programming language is R.
I am maintainer of R packages afex, MPTinR and acss.

Besides R, I use Python for running experiments (using PsychoPy) and occasionally other languages.

comment How can I create computer based psychology experiments using OS X?
@AnandJeyahar You should check out PsychoPy (psychopy.org) and OpenSesame (cogsci.nl/software/opensesame) two free software approaches that are what you are looking for. The only thing missing is a nice implementation of questionnaires and other simple item types. But I have some ideas based on PyQt4 and webkit. Let me know if you are interested in doing something.

comment How to assess participant awareness of experimental deception without inducing awareness?
I think the 'classical' introduction to funneled debriefings is Bargh, J. A., & Chartrand, T. L. (2000). The mind in the middle: A practical guide to priming and automaticity research. Handbook of research methods in social and personality psychology. (S. 253–285). New York, NY, US: Cambridge University Press.

comment Software for online psychological experiments that don't require users to download anything
We have done some serious test (using photoreceptors and other crazy equipment) at our lab using a 120hz LG Flatron W2363D (3D LCD monitors). The results were surprising. Almost all measures indicated advantages for the LCD (lesser dropped frames, ...). Unfortuanetly, the guy who did it does not want to write a paper about it. But I could ask him which measures he took.

@vizzero What do you expect? The OP wants something that runs in the browser, so timing will be comparatively horrible. The users will have all different kind of operating systems (probably most Windows) and a lot of different configurations (background programs such as antivirus, viruses (!), ...). So even if your program is good the shear amount of possible differences in user configuration will screw any reliable estimate.

Thanks. This is a lot more in the way of what I want to do. I hope there is an easy method to do this that also includes getting the POST command from the html-forms. I posted a smiliar question on SO yesterday: stackoverflow.com/questions/10121864/…

Its not that I dont want to program. I just want a way to present items (e.g., likert type) within an experimental session without the need to always program each question per hand in wxPython (which means positioning the text, the buttons, the box, ...).

I think my statement was ambigous. I want to maximally control what the participant is allowed to do (i.e., he should not be able to close the borwser). So I am more interested in a neat frontend than in the adaptive testing abilities. BTW: I tried the demonstrations on the concerto website and only the first one runs (with firefox and ie on win 7).

Thanks for this expansion. However, from what I get PsychToolbox does not really differ from PsychoPy or other related approaches (e.g., Tscope). You still need to completely draw the whole screen elementwise. This is not what I consider easy to use for presenting questionnaires. Especially not if you want something like radiobuttons, checkboxes and input fields and want poeple to use the mouse. I especially are looking for some program that uses a different approach.

Regarding your first question I mean multiple questions. And I am really interested in a as much as possible out-of-the-box front end for displaying questionaires within an experimental session on screen with maximum control of what the user is allowed to do and minimum programming hassle.

Looks interesting. Do you know if it is possible to have more than one item displayed onscreen? Furthermore, do you have an idea how to run it in a kind of controlled environment so that users cannot close the browser (better, there is no browser window) and need to perform the test?

My quick look at the homepage of PsychToolbox3 somehow gives the impression that it is another tool for running reaction time based experiments (i.e., a focus on accurate timing). Can you elaborate a little on which functions are intended to be used to display questionnaires and similar stuff?

@JeromyAnglim I really prefer free and especially non-pure web based as I intend to use it in combination with other approaches like PsychoPy.
