Stimulus Generators and software


  • Face generator: You are free (see web site) to download the demo version and then generate faces to suit. They come out with a little water mark when generated (they also have no hair).


Bodies: Two generators used by professionals and amateur animators alike.


Experiment generators and on-line particpant recruitment (crowd sourcing) sites.

  • PsyscopeX The classic experiment generator for the mac (updated and improved). It is a work in progress but it has been around for a while. It is easy to use and reasonably reliable. It’s also free.


  • PsychoPy concieved, built and designed by Dr Jon Pearce (University of Nottingham) as a free (open source) alternative to other ([insert brand name here]) experimental generators. This is a python programming language based experimental generator that works across all platforms.

It's an ongoing project and any bugs typically infrequent, often minor, and usually fixed by Jon and others, fairly quickly. Best of all it's  free, and it has a nice and fairly intuitive GUI if you don't like programming but you can get under the hood and get it to do pretty much anything you want. It’s also very easy to generate simple experiments e(including psychophysical types) using lists without any programming experience


  • Amazon Mechanical Turk (AMT) - This may appeal to some of you as research tool (it’s actually for crowd sourcing for research).

  • ProlificAcademic Pure crowd sourcing – UK based (I think) but with worldwide reach. They have an ethical pay rate (minimum wage).


  • Opesesame - More open source freeware that can be used to program experiments. It's python based and it is backended by PsychoPy. Mostly very easy to use and it has more colourful GUI than PsychoPy. Being open sourced and python based you can either use the GUI or get under the hood and code. It's also multi-platform.


  • Vision-egg - This is another s an Open GL hig level Python platform experimental generator for visual science experiments (largely). If you use this software please cite Straw, Andrew D. (2008) Vision Egg: An Open-Source Library for Realtime Visual Stimulus Generation. Frontiers in Neuroinformatics. doi: 10.3389/neuro.11.004.2008


  • jsPsych - This is a JavaScript library, for running experiments on teh internet in a web browser. The library was created by Josh de Leeuw (and others).

    • If you use it please cite: de Leeuw, J. R. (2015). jsPsych: A JavaScript library for creating behavioral experiments in a web browser. Behavior Research Methods, 47(1), 1-12. doi:10.3758/s13428-014-0458-y


Speech/sound analysis software:

  • Praat: Free (open GL) speech analysis software for acoustic analysis (by Paul Boersma, University of Amsterdam). It's also multi-platform.

  • Audacity ® is open source (cross-platform) software for recording and editing sounds. It’s free and very easy to use.

  • Pasrelmouth Praat Scripts in Python - This is a citable Python Jupyter Notebook to Measure Voice Pitch and HNR. you will need to make sure you have all teh libraries installed when you run it. Curtosey of David Fiendberg, via the OSF

Face Morphing software

  • Psychomorph - The best and it’s free though it is a bit tricky to get started with:


A version of this is also being developed here.  And an accessible and handy guide was developed by Clare Sutherland (University of York). It can be found here

  • FantaMorph - (not free) but pretty reliable and easy enough to use.


  • SqirlzMorph - Also free but has less control. It's fun though


  • MorphAnalyser (2.4) this is an independent web browser platform that allows you to view and manipulating 3D images. A very handy wiki can be found here.




  • Psytookit: From Glasgow University, this is part experiment generator and part teaching aid. It’s free and it’s rather easy to use. Also see wikipedia for a summary.

  • An Interactive Introduction to Fourier Transforms by Jez Swanson


Linguistic databases:



Psycholinguistics data bases:


DOIs getter:

If like me your reference manager does manage dois or (also like me) you are a bit half-hearted when collecting references and don’t have the dois try this free service:

Once registered all you need do is just import, copy/paste or type in your reference and then return it and your dois will be given to you…. If they are available.


Stats related 

  • From Rstudio - Rmarkdown for fully reproducible documents. Rmarkdown allows you to integrate your raw data, your analysis scripts, , the results of your analyses, and a narrative text, all together in one file.


  • StatCheck : Wanna check for errors in your reported statistics? A free online tool for just that job.
