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 -------------------- Can you spare some PC cycles to help FIND A CURE ..
