You are welcome! First, I want to say that effect in central vision is very small compared to effect in peripheral vision, for black and white ones. For color ones: Effect in central is same as in peripheral (L=CW, R=CCW), but again, far less intense, almost negligible.
Thank you!
この図形をステレオグラムで見たときに、周辺視による回転も起こるようです。目は平行法や交差法のほかにも複雑な動きを同時作業でおこなっているのでしょうか?とても不思議でした。図形は一つより複数あると回転が強く見えました。取り急ぎご報告まで。pic.twitter.com/BQRaTBwabM
