About:
OpenSesame is a cross-platform graphical experiment builder that provides an intuitive interface for designing complex cognitive and psychological experiments without programming knowledge. It supports Python scripting for advanced customization and integrates with various hardware devices for precise timing and data collection. The tool enables researchers to create, run, and analyze experiments efficiently across Windows, macOS, and Linux platforms.
Key Features:
  • Drag-and-drop interface for rapid experiment design
  • Python scripting support for advanced customization
  • Cross-platform compatibility (Windows, macOS, Linux)
  • Integration with lab hardware (eye trackers, response boxes)
  • Extensive plugin ecosystem for specialized functionality
Use Cases:
  • Designing cognitive psychology experiments for academic research
  • Creating perception and attention tasks for neuroscience studies
  • Running behavioral experiments in laboratory settings
  • Developing educational assessments and training modules
Alternatives:
  • PsychoPy – PsychoPy offers more programming flexibility but has a steeper learning curve
  • E-Prime – E-Prime is Windows-only and proprietary, while OpenSesame is cross-platform and open-source
  • jsPsych – jsPsych is web-based and JavaScript-focused, better for online studies
