Bottom Up Processing
|
Processing of Information... Done w/o referencing to any old information... ]
NEW information comes in and registers on receptors Incoming data |
|
|
Top Down Processing
|
Processing Information with the help of what's already stored in our memory
Our knowledge, experience, expectations |
|
|
Perception
|
Our perceptions are made with the help of both bottom up processing and top down processing
|
|
|
Depth Perception
|
Our ability to decide how far or big an object is
|
|
|
Monocular Cues
|
Cues that can be determined by one eye
Such as size, texture, linear perspection, motion parallax |
|
|
Binocular Cues
|
Cues of depth that can only be determined by two eyes
Such as distance |
|
|
Template Matching
|
Our perceptual system contains templates of every object / letter... in every position
HOWEVER...not possible since there's too many objects in the universe |
|
|
Feature Matching
|
Our perceptual system contains
|
|
|
Interactive Activation Model of Perception
|
Says there's THREE levels of Activation
1) Feature Level 2) Letter Level 3) Word Level |
|
|
IAM - Feature Level
|
Feature Units like Lines
|
|
|
Letter Level
|
Contains letter units for each letter in the alphabet
|
|
|
Word Level
|
All the words a person knows
|
|
|
Feature Integration Theory
|
two stages of perception; preattentive stage and the focused attention stage
|
|
|
FIT - Preattentive Stage
|
Stage where our perceptual system takes in the simple info, such as as the shape of the book, and it does it really quickly and automaticaly
Object is analyzed into its features |
|
|
FIT - Focused attention Stage
|
Stage where the random free floating objects are put into perspective
the features are combined so we can perceive the object |
|
|
Recognition by Components Theory
|
A theory of perception in which features are not lines, curves or colors, but 3D volumes known as GEONS.
|
|
|
Geons
|
R.C.T
3d volumes shapes such as cylinders, rectangular solids, and pyramids 36 different types help contruct the large proportion of objects that exist int he environment |
|
|
View Invariance
|
Property of Geons that says they can be ID'd when viewed from different angles
|
|
|
View Invariant Properties
|
RCT - Geons
Properties that remain visible even when the geon is viweed from different angles |
|
|
Discriminability
|
Each geon can be distinguihed from the others from almost all viewpoints
|
|
|
Resistance to visual noise
|
Geons can be identified under noisy conditions such as FOG or low light
|
|
|
FFA
|
Neurons in the Fusiform Face Area of the temporal loble
RESPOND TO FACES |
|
|
PPA
|
Parahippocampal Place Area
Neurons activated by pictures of indoor and outside scenes |
|
|
EBA
|
Extrastriate Body Area
Actviated by pictures of bodies and parts of bodies |
|
|
Pupil
|
Gathers VISUAL INFO
Fixations - wherever the eye is focused, the eye will take in that visual info |
|
|
Fovea
|
Light from direct focus lands in the Fovea
|
