|
Feedback Activtion
|
The activation that is sent from word units back to each of the letter units for that word
|
|
Why is the interactive activation model important?
|
It proposes a mechanism that is consistent with what we know about neural firing - excitation is sent from level to level, just as in neurons
|
|
Preattentive Stage
|
Happens automatically and doesnt require any effort or attention by the perceiver - this is the state in which the object is analyzed into its features
|
|
Illusory Conjunctions
|
The combination of features from different stimuli
|
|
Focused attention stage
|
In this stage, the features are combined and we perceive the object
|
|
Focused attention Stage
|
During this stage the observer's attention plays an important role in combining the features to create the perception of whole objects - this eliminates illusory conjunctions
|
|
Geons
|
3D volumes - Biederman proposed that they are 36 different geons. Geons have the property of being able to be identified when viewed from different angles
|
|
Properties of Geons
|
View Invarient Properties - Properties that remain visible even when the geon is viewed from many different angles
Discriminability - Each geon can be distinguished from the others from almost all viewpoints Resistance to Visual noise - we can still perceive geons under noisy conditions such as fog or low lighting |
|
Basic message of recognition by Components Theory
|
If enough information is available to enable us to identify an object's basis geons, we will be able to identify the object - shows that we can recognize objects based on a relatively small number of basic shapes
|
|
Proximity
|
We consider things that are close together as part of the same item
|
|
Similarity
|
This occurs when objects look similar to one another, we often perceive them as a group or pattern
|
|
Good Continuation
|
This occurs when the eye is compelled to move through one object and continue to another object - we tend to look for what flows in the environment and piece things together that are adjacent to each other - camouflage
|
|
Closure
|
If we have separate pieces of an item that are not attached to one another, we tend to impose meaning, closure, onto the object as a whole - like when an object is incomplete or a space is not completely enclosed
|
|
Binocular cues
|
Uses information given from the disparity between your two eyes to determine depth of the object you are looking at - depends on how different the 2 images in each eye are
|
|
Linear Perspective
|
The perspective that as things get farther away, they get more narrow - railroad tracks
|
|
Relative Size
|
The idea that images which are larger are close to us than images which are smaller
|
|
Interposition
|
When we make decisions about whether things are close or near by whether they are covering up something else
|
|
tecture gradients
|
the idea that things that are closer to us tend to have more definition than things that are further away
|
|
Displacement over time
|
You can tell that something is moving because as time passes it changes places in your retina over time
|
|
Induced movement
|
Something else is moving and because of its movement we tend to make judgments about how we are stationary and the other thing is moving
|
|

|
Attention Perception
|
Paying attention to something increases the chances you will perceive it

|
Cognitive process that allows us to process a limited amount of information from the enormous amount of information that is available and is a conscious and unconscious process
|
|
Automatic Attention
|
No Conscious Control - It is an automatic way of dealing with stimuli that are coming in
Minimal effort - It demands little or no effort on the cognitive system Speed - These processes are performed relatively quickly Parallel Process - You can do it at the same time you are doing other things |
