What is a PSY file?

PSY files mostly belong to OpenSesame. PSY files serve as experiment script files in psychology research.
Main use: They store instructions that control experiment flow, timing, and stimuli presentation.

Experiment scripts: Most PSY files are created by tools like OpenSesame. They contain specific commands and parameters used to run cognitive and behavioral tests.
Alternative format: Some PSY files are used on Inquisit platforms (linked to E-Prime) and follow a similar scripting approach.
Profiling data: A minority of PSY files use the JetDB format, which stores profiler data. This type is managed with tools such as JetBrains PyCharm.

FilExt.com tip: For further details on psychology experiments, visit the Cognitive Science website. For profiler data examples, see JetBrains PyCharm.

How can I open a PSY file?

You need a suitable software like OpenSesame to open a PSY file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your PSY file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a PSY file directly in the browser:.
