- 46. Lothar Spillmann, Joe Hardy, Peter Delahunt, Baingio Pinna, and John S. Werner Tube illusion UCD Medical Center, USA;University of Freiburg, Germany;PositScience, USA;University of Sassari, Italy Take a cardboard tube, such as from a kitchen paper role, and hold it close to your eye, while keeping the other eye open. Look at a bright wall. The disk-shaped area seen through the tube will appear strikingly brighter than the same surface area viewed by the other eye. The effect is reminiscent of a flashlight illuminating the area under consideration. The effect takes a few seconds to fully develop. It also works with a textured surface where it enhances not only the brightness and color, but also the detail.

- Not to claim that the only thing going wrong here is picking the right features!
- Silencing illusion
- Face adaptation phenomenon. Explanation: brain contains populations of face sensitive neurons. Neurons adapt, in a similar way as occurs during colour adaptation. Different faces adapt different face neurons.

- In the Illusion of Sex, two faces are perceived as male and female. However, both faces are actually versions of the same androgynous face. One face was created by increasing the contrast of the androgynous face, while the other face was created by decreasing the contrast. The face with more contrast is perceived as female, while the face with less contrast is perceived as male. The Illusion of Sex demonstrates that contrast is an important cue for perceiving the sex of a face, with greater contrast appearing feminine, and lesser contrast appearing masculine. Russell, R.

- perception at different scales
- referred to as inattentive blindness, we’ll later see that attention is a critical part of perception
