VISUAL PSYCHOPHYSICS ENGINE

The Visual Psychophysics Engine is a versatile software tool for ViSaGe that was developed by Dr Neil Parry (Clinical Vision Scientist, The University of Manchester). It is supplied with a suite of pre programmed experimental paradigms which allow you to measure luminance and chromatic Contrast Sensitivity Functions, increment thresholds and De Lange curves. You can also create your own bespoke protocols and present standard visual stimuli like sinewave gratings and Gabor patches using the easy-to-use, menu-driven interface.
