Motion Perception

Motion Perception:

Definition: Shrinking objects are perceived to be retreating. Enlarging objects appear to be approaching. Large objects appear to be moving slower than small objects.

The baseball is large in this picture, especially in comparison to the baseball player. This is an example of motion perception because the baseball seems to be coming toward you.

Monocular Cues

Monocular Cues:

Definition: Depth cues such as interposition and linear perspective that are available to either eye alone.

Interposition: If one object partially blocks the view of another, we perceive it as closer. Parallel lines such as railroad tracks seem to converge with distance.

Linear perspective: The greater the convergence, the greater the distance perceived.

The railroad tracks seem to be converging as the distance grows farther away.

Perception Law 6

Binocular Cue
      A Binocular Cue is using both eyes to identify if objects are close or far away. Because your using both eyes it helps with your depth perception.

         These two apples may look close to each other, but you are using a binocular cue to help tell you that one is in front of the other. With both eyes it is easier to see depth perception and know that one apple is in front of the other. If you were only using one eye it would be very difficult to tell if the apples were side by side or is one in front of the other. Two eyes( binocular cue) is much more efficient at using depth perception.

Perception Law 5

           Figure-Ground Perception 

Figure-ground perception is when we simplify a scene into simpler objects and focus on either the figure or the ground/ back round.

This is a good example of figure ground perception because there is two images that one could see. You can focus on the figure which would be the man playing the saxophone or the back round which is a picture of a women's face. This demonstrates figure ground perception because this photo forces you to focus on either the figure or the ground/back round.

Perception Law 4

      Proximity

        Proximity is how we group items together depending on the space between them, it helps us groups items together that are close or far away from each other.

Take these skittles for instance, instead of seeing eight individual skittles
 our brains automatically see that there is two groups of skittles. The distance between the two groups is enough to help us distinguish two groups. Proximity helps us group items that are close or far away from each other.

 

Perception Law 12

Shape Constancy

Shape constancy is the tendency to perceive an object as having the same shape regardless of its orientation or the angle from which we view it. 

An example of this is a door opening. We know the door is a rectangle, and when it's opened we see it as a smaller, trapezoid. We still recognize that it’s in the shape of a rectangle, but really, from that angle, the image processed by our retina is that of a trapezoid. Our brain compensates for the distortion of the shape by taking into account visual cues about distance and depth to keep our perception of the frame constant.

Perception Law 11

Brightness Constancy

Brightness constancy explores human visual perception of neutral colors (white, black and gray, they all have brightness, but no hues). This is a theory that states though these colors, when they are seen in isolation on a blank screen appear to emit light, when paired with a surrounding ring of different brightness, those items will no longer appear to emit light.

An example of brightness constancy is the moon lighting up a dark sky. It appeared to be admitting off light, even though it's not really.

Perception Law 10

Size Constancy

 Size constancy is the tendency to see an object as the same size regardless of whether it's far away or close.

An example of size constancy is a city skyline. We know the buildings are very tall, even from far away. If we hold our hand out the buildings are smaller, but because of size constancy, we still know the buildings are tall.

Perception Law 3

Law 3: Similarity
The law of similarity is where objects that are similar in appearance are usually assumed to be a part of the same group.

This is an example of the law of similarity because both of these eyeliners look the same and people could assume that they are the same. However, both of these are different and people could find that out by looking at the label. The top eyeliner is sapphire and the lower one is black.

Perception Law 2

Law 2: Continuity
The continuity law is when objects are in a continuous form, they are usually perceived as being a part of the same group. 

These colored pencils represent the law of continuity because they are in a line and many people might perceive them as the same group at first glance. This is because they are similar in color but is a pale blue, the second one is green, the third one is aquamarine and the last one is medium blue.

Perception Laws 1

Law 1: Closure

The closure law means that objects that appear to make an image are perceived as being a part of the same group even when they're not. 

This picture is an example of the closure law because it forms the image of a smiley face and people could assume that the notes are apart of the same group but the first note is a B flat and the second note is a G.
