12.2 Software

We assume you will use an experimental software (e.g. Matlab, Habit, E-Prime, Psychopy, OpenSesame or custom software) to run the study and one of three settings to record looking times:

  1. Offline Video recording
  2. Eye-tracker (e.g. Tobii, EyeLink, SMI, ASL, or a different company) with appropriate software from the eye-tracker or custom software
  3. Eye-tracker + video recording.

We also assume you know how to set up looking-time studies on your equipment. If that is not the case, or if you need help, support is available from the following people:

  • PsychoPy:
  • PyHab:
  • Tobii:
  • Eyelink:
  • Other systems: email us (mb5@manybabies.org) and we’ll do our best to help out
