Perception

process of organizing and interpreting information, enabling us to recognize meaningful objects and events.

geslalt philosophy: whole is greater than the sum of its parts.

figure ground relationship: organization of visual field into objects (figures) that stand out from their surrounding (ground).

grouping: perceptual tendency to organize stimuli into groups that we understand. based on proximity, similarity, continuity, and connection.

depth perception: ability to see objects in 3D although the image that strike the retina are 2D allows to judge distance.

binocular cues - retinal disparity: a binocular cue for seeing depth.
closer an object comes to you the greater the disparity is between two image.

monocular cues:
interposition: if something is blocking our view, we perceive it as closer.
relative size: if we know that two objects are similar in size, the one that looks smaller is farther away.
relative clarity: we assume hazy objects are farther away.

texture gradient: the coaser it looks the closer it is.
relative height: things higher in our field of vision, they look farther away.
relative motion: things that are closer appear to move more quickly.
liner perspective: parallel lines seem to converge with distance.
light and shadow: dimmer objects appear farther away because they reflect less light.

motion perception: we perceive motion incredible well/ we judge mostly by the size of the object.

phi phenomenon: allusion of movement created when two or more adjacent lights blink on and off in succession.

perceptual consistency: perceiving objects as unchanging even as illumination and retinal images changes.
