This study introduces the CFS toolbox, an open-source MATLAB program for creating continuous flash suppression (CFS) experiments. Researchers can easily design complex visual perception studies with customizable parameters and minimal coding knowledge.

Area of Science:

  • Cognitive Neuroscience
  • Psychology
  • Computer Science

Background:

  • Continuous Flash Suppression (CFS) is a technique used to render visual stimuli invisible.
  • Implementing CFS experiments traditionally requires significant programming expertise.
  • A need exists for accessible tools to facilitate CFS research.

Purpose of the Study:

  • To introduce the CFS toolbox, an open-source MATLAB-based software.
  • To provide researchers with a user-friendly platform for designing and conducting CFS experiments.
  • To enable flexible customization of experimental parameters for diverse research questions.

Main Methods:

  • The CFS toolbox is built using MATLAB and leverages PsychToolbox-3 (PTB-3).
  • Experiment parameters are configured via editable CSV files.
