## What is iNSIGHT Illusions Aftereffects?

Illusions are fun and interesting to view, but more importantly they provide insights into how our visual system works. By discovering ways in which the visual system can be “fooled,” we can learn something about the way we see. Some effects require red-green or red-blue glasses.

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
