How does DMDX work?

Stimulus Files

• These are files that contain the stimuli that you want DMDX to display

  1) Speech Files (.wav)
  
  2) Picture Files (.bmp)
  

• NB: Written words are typed directly in the item file

Item Files

• These are simple files that contain a sequence of instructions telling the software (amongst other things)

  1) What stimuli to present to subjects
  
  2) How long to present them for
  3) When to start measuring response times
  4) What response to expect (yes/no)

• Item files are divided into two sections

  • header lines
  • item lines
