Motion & Time
»Stepping feet« illusion 1 – strong, beautiful and (relatively) easy to understand
Motion Induced Blindness – an unexplained optical illusion of disappearing dots
Stereokinetic Phenomenon – an optical illusion of 3D from motion (aka »kinetic depth effect«)
»Rotating Snake« Illusion – with a new explanatory twist
Pinna-Brelstaff Illusion
Motion Aftereffect – also known as »waterfall effect«
Spoke Illusion – a motion illusion + an unexpected (?) aftereffect
Stroboscopic Artifacts – making a teaching point out of a nuisance
Sigma Motion – an optical illusion due to an interaction of image dynamics and eye movements
Eye Jitter – more on eye movements, involuntary ones
Biological Motion – for me the most beautiful class of visual illusions
Flash-lag Effect – moving and stationary objects perceived at different times
Ramp Aftereffect – an aftereffect in time
Enigma by Isia Leviant
Reverse Phi Motion – something for the specialist
»Stepping feet« illusion 2 – radial version of »Stepping feet 1«, weaker
Motion-Bounce Illusion – sound influencing perception of motion (crossmodally)
Motion Binding
Missing-fundamental motion inversion
Frequency-doubling illusion
Luminance & Contrast
Hermann’s Grid – fleeting luminance illusions
Hermann’s Grid bent – a new twist, refuting the classical explanation
Scintillating Grid – strong fleeting luminance illusions
Induced grating – classical brightness contrast
Craik-O’Brien-Cornsweet – collaboration of retina & cortex
Wertheimer-Koffka-Ring – pitting Gestalt vs. lateral inhibition
Simultaneous Contrast – here dynamic
Pyramid Illusion – Vasarely revealed
Munker-White Illusion – contrary to lateral inhibition
Adelson’s »Corrugated Plaid« – context affecting brightness
Adelson’s »Checker Shadow« illusion – more context affecting brightness
Contrast Constancy – demonstrating space-average-based contrast gain control
Contrast Gain Control – demonstrating temporal contrast gain control
Colour
»Lilac Chaser« – a rapid aftereffect, you pursue colours which aren't really there
Benham’s Top – colour from spatio-temporal patterns
Neon Colour Spreading
Structure from motion – fails at equiluminance
Geometric- & Angle Illusions
Hering Illusion – and other angular interactions
Poggendorff Illusion – a classical geometric optical illusion with a new twist
Fraser’s Spiral
»Café Wall« Illusion
Size Constancy
Müller-Lyer Illusion – test your bisection accuracy
Moon illusion
T-illusion
Luminance Looming
Shepard: “Turning the Tables”
Shepard: “Subterranean Terror”
Cognitive- / Gestalt Effects
Blur & picture content – spatial filtering (or high frequency masking)
Hidden message – blur & figure-ground discrimination
Kanisza’s Triangle – depends on context
Blotted letters – Gestalt completion
Hidden Figures – Dalmatian Dog with 2 helpers
Rotation – changes the interpretation
Impossible Objects – draw your own impossible object
What’s special about faces?
Rotating face mask – hollow faces
Find the Face (in the Beans) – a picture puzzle
The face on Mars – imaginations of perception
The »Thatcher Illusion« – inverted faces lose their emotional message
Dr. Angry and Mr. Smile – two messages in two spatial frequency band
The Lincoln Effect
