🧪 Visual Psychophysics Perception Simulation Signal Detection

This simulation explores the fundamental principles of visual psychophysics – how our brains perceive brightness and contrast. By adjusting stimulus intensities and introducing controlled noise, you can investigate how observers make judgments about signal strength and uncover biases in their perceptual processes.
