Transform your dmdx result file in a text file with the item number, its conditions, the rt, and the errors in a way that you will be able to import in any statistical software (I use it intensively). If you use it with a set of tools I’ll soon post, you’re able to make analysis of dmdx experiments in a few minutes.
  • Pcut 1.01 [Perl script] Allow to extract the columns in the order you want. (an advantage if we compare it to cut (in textutils)
  • Transpose 1.00 [Perl script] Transforms a file organised by columns in a file organised by lines.
    Original file
    a 0
    b 1
    c 2
    Output file
    a
    b
    c
    0
    1
    2
  • Mean 1.24 [Perl script] If your file is organized by lines, it computes the mean of your line, removes the outliers (+/- two standard deviations but you can change that in the source code).
    Finally it writes:
    -An output with your conditions and the resulted mean.
    -An output with your items and which are outliers.
  • Listes de fruits et légumes et d’animaux Réalisant des expériences sur la sémantiques et n’ayant pas trouvé de listes présentant les fruits et légumes et/ou les animaux en français, j’ai réalisé mes propres listes: -liste de fruits/légumes -liste d’animaux

Useful tools for psycholinguists

  • R (a very powerful free software for statistics , if you want a graphical interface, try it with Rcmdr or pmg)
  • Perl (a powerful tool for manipulating texts; it is with perl that I made the database Lexique)
  • Ultraedit (a very powerful text editor; you have to pay, but it’s worth the price and better than any free software editor)
  • Var3 (an easy and powerful software for ANOVA’s. This version is working under XP thanks to Thérèse Collins)
  • Photos gratuites : 30 sites donnant accès à des photos gratuites (comme Stock Exchange)

Experiment generators

  • E-Prime (a good experiment generator; good support)
  • PxLab (a good free experiment generator; almost no support)
    • Dmdx (a free experiment generator; read this page before trying dmdx)
      Used  with CheckVocal, it’s far the best solution for the moment for naming experiments.
  • UsbMouseRate (software to change your usb polling rate to 1 every ms with win2000/XP)
