Perception Flashcards
monocular depth cue
depth perception in one eye
position
objects higher in the visual field are perceived as further away
Examples of monocular depth cues
position, aerial perspective, linear perspective, relative size, interpolition
binocular depth perception
depth perception in two eyes
depth perception
how the eyes perceive the 3D world
Relative Size
smaller objects are perceived as farther away
Interposition
when one object overlaps another, it is perceived as closer
linear perspective
parallel lines seem to converge as they go further into space
Aerial Perspective
hazy objects appear further away
Photoreceptors
Rods and Cones
Rods
not sensitive to color, senses grays and black
Cones
sense bright colors (red, green, blue)
Ponzo Illusion
Both of the lines are the same size, however the line that is above appears smaller than the line that is on the bottom of the picture. This is because of the position of the yellow lines on the converging lines
Muller-lyer illusion
Both of the lines are the same size, however people perceive line b as longer than line a. The reason for this is because people compare it to architectural features in our 3D world.
light illusions
Both of the circles are the same color, they appear different because of the light and darkness surrounding them. Same with the squares, they are the same color, one of them just looks darker because it is in the shadow.
