Lecture 11 Summary of adaptation
phenomena Geometrical illusions
2
Broad view on adaptation and sensitivity
adjustments Short-term vs. long-term
adaptation Very short-term priming? Short-term,
long-term Afterimages, Aftereffects other
senses (hearing, touch, motor)? Very long-term
Evolution Animal/human behavior/crime (e.g.,
infanticide) physiology, disease risks (e.g.,
obesity)

Geometrical illusions
Müller-Lyer - line segments of equal
length? Zöllner - parellel lines? Hering - local
orientation contrast? Orbison - bent
lines? Fraser - circles or spirals? Poggendorff -
co-linear? Ponzo - length/size at different
distances (linear perspective) Vertical-horizontal
- equal length? Café wall - parallel
lines? Ebbinghaus - same size? Jastrow - same
shape? Shepherd - same shape?
