App Description
Mach bands are an illusion produced by the communication between neighboring cells in the retina. Because nearby cells can inhibit each others’ responses (lateral inhibition), our perception of edges is enhanced. Learn how lateral inhibition can enhance edge perception, and create illusions that demonstrate Mach band effects.
iNSIGHT is a curriculum supplement for experimental psychology, sensation and perception, vision science, and optometry lab classes. There are two different types of iNSIGHT apps: experiments and interactive demonstrations. Experiments are real psychophysical procedures (NOT simulations) that generate real data. Demonstrations illustrate a visual phenomenon and allow students to manipulate the effect. Each lab is complete with a quick-start guide, detailed instructions, background information, and one or more guided exercises. To see how iNSIGHT works, try the FREE iNSIGHT Color Mixing app.
A printable PDF Student Guide that contains the exercises and other supporting materials, and a Teacher Guide are available at www.polyhedronlearning.com/see_apps_insight.html
