Those characteristics that make some stimuli more compelling no matter who the perceiver is.
|
|
|
Personal Factors may be defined as...

|
Contrast
|
|
|
Contrast, in relation to stimulus factors, can be defined as...
|
The extent to which a stimulus is physically different from the other stimuli around it.
|
|
|
All else being equal, the more often a stimulus is presented the more likely we are to attend to it or perceive it. This is an example of the stimulus factor known as __________.
|
Repetition
|
|
|
Personal Factors that can influence perception can be categorized as...

predisposed, or expect to perceive something, we have formed what? |
A Mental Set

|
An attempt to organize, identify, and store stimuli in our memory based on information derived from our senses is an example of ...

1. Proximity (or Contiquity)
2. Similarity 3. Continuity 4. Common Fate 5. Closure |
|
|
Stimuli occurring close together in space and time are perceived as belonging together and part of the same figure is a principle known as
|
Proximity (or Contiquity)
|
|
|
The principle claiming that stimuli that are alike or share properties tend to group together in perception.
|
Similarity
|
|
|
The principle claiming that we tend to see things as ending up consistent with the way they started.
|
Continuity
|
|
|
The tendency to group together in the same figure those elements of a scene that appear to move together in the same direction and at the same speed.
|
Common Fate

|
|
With regard to perceptual organization according to the bottom-up approach, filling in the gaps in our perceptual world is known as...

|
A phenomenon that many psychologists believe to be a special case of closure is...
|
The perception of SUBJECTIVE CONTOURS. Which is...

2. Another white triangle 3. Square |
|
|
One of the most important principles of Psychology as it affects our everyday lives and the central importance of perception in our everyday lives is...
|
What matters most to us is NOT what actually happened, but what we PERCEIVE to have happened.
|
|
|
The ability to judge depth and distance reflects that we are simultaneously responding to a large number of _____ to depth and distance.
|
Cues
|
|
|
Cues that involve both eyes are called...
|
Binocular cues
|
|
|
The cue to depth derived from the fact that each eye gets a different view of the same three dimensional
object. |
Retinal Disparity
|
|
|
The observation that a perceiver's
eyes turn inward toward each other when viewing something up close. |
Convergence
|
|
|
The process of changing the shape of the lens by contraction and relaxation of the ciliary muscles to focus images on the retina.
|
Accommodation
|
|
|
The six most important physical cues (sometimes called pictorial cues) we get from the structure of our environment are...
|
1. Linear Perspective
2. Interposition 3. Relative Size 4. Texture Gradient 5. Patterns of Shading 6. Motion Parallax |
|
|
The fact that portions of objects that are spatially further away from our eyes appear smaller than portions that are spatially nearer our eyes.
|
Linear Perspective
|
|
|
The fact that objects in the foreground (spatially closer) tend to obscure objects in the background (spatially further away)
|
Interposition
|
|
|
Since very few stimuli in the world change their size, objects that appear larger are judged to be close. Conversely, objects that appear to be small are further away.
|
Relative Size
|
|
|
The fact that detail is more readily distinguished at closer distances.
|
Textural Gradient
|
|
|
How objects create patterns of light and shadow.
|
Patterns of Shading
|
|
|
When viewed from a parallel perspective, at speed, objects farther away appear to be stationary or moving much slower than objects spatially nearer.
|
Motion Parallax
|
|
|
True or false: perception of depth and distance is NOT susceptible to cultural constraints.
|
False
