About Simon Task - Cognitive Conflict Research Kit
- Art & Visuals > 2D
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.
Simon Task - Cognitive Conflict Research Kit gives you a single, well-organized component (SimonTask.cs) that runs the entire experiment: fixation, stimulus presentation, response collection, feedback, breaks, and a results screen - fully driven by Inspector settings.
Highly customizable, all through the Inspector:
Choose the stimulus modality: Word, Color, Shape, Image, or Audio
Define any number of response categories - each with its own key, color, word, sprite, or audio clip, and its own on-screen "home" position
Control the exact mix of congruent / incongruent / neutral trials
Fine-tune every timing value: fixation, stimulus duration, response window, inter-trial interval (with optional jitter), block pauses
Choose feedback behavior: immediate, end-of-block, or none - and whether feedback shows as text, stimulus recoloring, or both
Fully rewritable on-screen instructions and feedback texts
Suited for:
Cognitive psychology research and teaching demonstrations
Reaction-time / cognitive-conflict studies and screening tools
VR-based cognitive assessment (optional SteamVR integration)
Any project needing a validated, well-documented reaction-time paradigm as a building block
Included out of the box:
7 ready-to-use example scenes and prefabs (one per stimulus modality, plus a neutral-baseline and an advanced 3-choice variant)
License-free example graphics and audio - safe for commercial projects
Automated EditMode/PlayMode tests covering the core trial and statistics logic
Full written documentation covering every Inspector setting
Supported VR Device Types via SteamVR:
Vive
Oculus
Because 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.
