PsychoPy
For running psychology and neuroscience experiments
...The software provides precise control over visual and auditory stimuli, experimental timing, and participant responses. Researchers can create experiments through a graphical Builder interface or develop customized procedures using Python scripts. PsychoPy supports behavioral measurements, stimulus presentation, and integration with specialized research hardware. Experiments can run locally, while compatible studies can be deployed online using JavaScript and Pavlovia. Its flexible architecture and extensive experimental design capabilities make it suitable for students, educators, and researchers conducting reproducible scientific investigations.
