Perception Laws Blog

A. Rules of Perceptual Organization:
1.  Closure:
Separate objects grouped together are seen as a whole. This image appears to be a triangle but really it is just an empty space.


2.  Continuity:
Points that are connected by straight or curving lines are seen in a way that follows the smoothest path.



3.  Similarity:
Similar auditory and visual stimuli tend to be grouped together. These dots are all together but seem separate due to their color.



4.  Proximity:
Objects near each other tend to be grouped together.  An example is in this picture below a group of circles, the ones on the left may appear to be grouped in horizontal rows while the ones on the right tend to be grouped in a vertical column.




5.  Figure-Ground Perception:
Reality is organized or reduced to the simplest forms possible.





B. Binocular Cue:
are based on the receipt of sensory information in three dimensions from both eyes.  Ex. Hold a finger a foot from your face and view it with both eyes then with your left and then only with your right.




C. Monocular Cues:
 -relative size: if two objects are the same size we perceive a smaller image as farther away. Ex: a car mirror


-relative clarity: we perceive hazy objects as farther away than sharp,clear objects. Ex: near sighted people.


D. Motion Perception: process of inferring the speed and direction of elements in a scene based on visual, and vestibular inputs. Ex: watching lights flash.



E. Perceptual Constancies



1.  Size Constancy- A type of visual subjective constancy.  People's perception of a particular object's size will not change, regardless of changes in distance from the object.  Ex.  Viewing New York's skyline from a distance, the buildings are actually very tall.




2.  Brightness Constancy- Our ability to view objects as continuing to have the same brightness even if light may change their sensory properties.  Ex.  A sheet of white paper in the daylight sun reflects a different amount of light than the same white paper in moonlight, but we perceive the paper as having the same whiteness in both cases.



3.  Shape Constancy- When our perception of the shape of an object doesn't change regardless of changes to the object's orientation.  Ex.  When looking directly at a framed picture, we understand that it's the shape of a rectangle.  If we walk somewhere and view the same picture from an angle, we still understand it is in the shape of a rectangle,but from that angle, it is actually a trapezoid.
