The McCollough effect in children.

In experiment 1, children between the ages of 6 and 9 years binocularly viewed red vertical and green horizontal gratings for several minutes. This would, in adults, produce a reliable orientation-specific McCollough effect, and it was present in the children. In experiment 2, a second group of children viewed the adaptation patterns with only 1 eye, the other eye being occluded. The McCollough effect was present when the adapted eye viewed the test pattern, but, as in adults, no interocular transfer was found.
