The Simon task demonstrates that people react more swiftly and accurately when the characteristics of a stimulus and its response align.The Simon task and effect, first identified by J. R. Simon and his colleague in 1963, demonstrate that people react more swiftly and accurately when the characteristics of a stimulus and its response align, such as both occurring on the same side of the body. This phenomenon is part of the broader category of stimulus-response compatibility effects. It is similar to the Stroop effect in highlighting the challenges experienced during a mismatch between a stimulus and its response, which is easily noticeable.Supported VR Device Types via SteamVR* Vive* OculusBecause all creation and editing functionalities are accessible through the Unity Editor, no coding is required to create and run a custom questionnaire in a scene.For further reading, see:Simon, J.R. and Wolf, J.D.
