What are the 5 Gestalt grouping principles |
|
Definition
Proximity
Continuity/good continuation
Similarity
Closure
Good Form |
|
|
Term
|
Definition
Things that are close to each other are seen as being members of a group, while things further apart form a different group e.g. XXX XXXX |
|
|
Term
Continuity/Good Continuation (gestalt) |
|
Definition
If objects fall along a smooth contour, they will be grouped. |
|
|
Term
|
Definition
Our visual system tends to close gaps, or fill in missing bits e.g. Panda Picture.
Your brain is processing the info, and that processing emphasizes some bits of info (like edges) so that in the situation where the info is degraded (by e.g. fog) the brain can fill in the missing info, it tries to recover the info. |

Definition
If the marks tend to form a single, simple shape then they will be grouped |
|
|
Term
perceptual constancies include |
|
Definition
Size constancy
Shape Constancy
Colour Constancy |
|
|
Term
Size constancy (perceptual constancies) |
|
Definition
Tend to see things as being the same size, even though they are actually smaller on the retina when they are further away. results in part because the world is 3D. The brain takes into account the fact that the size of something on our retina will get smaller if we view the object from a distance |
|
|
Term
Shape Constancy (perceptual constancies) |
|
Definition
The projected shape of an object can be quite differnt from the perceived shape. e.g. table top. Our knowledge from the 3D word, is used by our visual system to influence our perception of that info that is received at the retina |
|
|
Term
Colour Constancy (perceptual constancies) |
|
Definition
Tendency to see colour as unchanging. e.g. jumper colour is seen as the same in dark and light. Colour is perceived in a relative manner, meaning relative to the colours of things nearby. |
|
|
Term
Monocular depth cues (Pictorial cues) |
|
Definition
Texture gradients
Occlusion
Atmospheric perspective
Relative size
Perspective
Hight in the visual scene |
|
|
Term
Texture gradients (Pictorial cues) |
|
Definition
As things get further away from you the project smaller images on your retina. This gradient can be used to estimate depth. e.g. sand on beach |
|
|
Term
Occlusion (Pictorial cues) |
|
Definition
Things that are in front of other things tends to be closer |
|
|
Term
Atmospehric perspective (Pictorial cues) |
|
Definition
Things further away appear more hazy, and the colours tend to be bluer (due to things such as dust) |
|
|
Term
Relative size (Pictorial cues) |
|
Definition
size of the retinal image is used to enhance our perception of depth not to change our perception of the size of the object (size consistancy) |
|
|
Term
Perspective (Pictorial cues) |
|
Definition
Parallel lines tend to appear to converge, or come closer together, as they recede into the distance |
|
|
Term
Height in the visual scene (Pictorial cues) |
|
Definition
When you look out over the landscape, things that are further away tend to be higher in the visual scene then things that are close to you. |
