OpenSesame

OpenSesame: A great utility for creating complex psychological experiments

OpenSesame is a nice software that was designed for users that want to build psychology-related experiments and is also suited for creating complex experiments in the neuroscience and experimental economics fields.

It was also designed from the start to be able to use devices like eye tracker, button boxes, and EEG equipment.

You will be able to customize the core functionality by adding Python codes to your experiments, but you will probably need to watch some tutorials in order to do this, on the developer's website.

The application offers you a toolbar that you will be able to quickly access to some of the main features and commands (e.g. on the left there's a compact panel that offers direct access to commonly used tools, and right next to it, an Overview panel that will display the structure of the experiment.

Another thing to remember is that it's cross-platform, which means that you can run it without any problems on all operating systems (e.g. Windows, macOS, and Linux).

OpenSesame is a reliable utility software that if you take the time to read and watch all its tutorials and learn all of its functions, it can help you develop complex psychological experiments.
