JJ Gibson
1. all we need to see 3-D is in retinal image
2. Visual scene is analyzed in whole objects rather than parts
3. Impression of depth or distance coes immediately w/ out computation or info from experience |

Describe Modularity of Perception.
Who first came up with it? |
|
Definition
The mind has a distinct set of units or modules, each of which is complete in itself and has a specific function with dedicated neural hardward that can do a specific bit of processing or computation.

Describe the theory of intelligent perception. Who is accreditted with this theory?
What is it AKA? why? |
|
Definition
Perception is like other mental processes in that, in addition to the info available at the moment, we can use info based on our previous experience, our expectations and etc...
Helmholtz
AKA-constructive theories of perception- because several sources of info are combined to build or asssemble our conscious experience of what is out there |
|
|
Term

Definition
| Cues- signals in the stimulus that function to shape our perceptual responses. not always conscious of them. |
|
|
Term
| Pictoral depth cues are also called ______ cues. Why? |
|
Definition
| Monocular cues- because they not only appear in pictures but are also available when only one eye is used to view a scene. |

|
Definition
| Light, geometry of images |
