Chapter 3 Flashcards
What is Perception?
The process of organizing, interpreting, and making sense of the
sensory information received through sensation
Why are Perception and Sensation not the same thing?
- Sensation: the process of detecting and
receiving information from the external
environment or from within the body - Initial automatic response to the physical
stimuli - Perception is not an accurate
representation of the realit
What is the bottom up process?
we allow the stimulus itself to shape our perception, without any preconceived ideas.
What is a example of bottom up proccessing?
Light (Physical Stimulus) goes into our eyes and through the various structures untill we analyze the image in the brain
What are binocular cues?
Bioncular Disparity and COnvergence
What is binocular Disparity?
Two eyes view the world from slightly different angles, resulting in retinal
disparity
What is convergence?
The closer, the more the eyes rotate inwards to focus on the object
Enables your eyes to have a sense of depth perception
What are the 3 Monocular Cues?
Occlusion
Texture Gradient
Motion Parallax?
What is oculusion?
Objects that partially block other parts of the scene are perceived to be closer to an observer than the blocked objects
What is Texture Gradient?
objects appear closer because they are coarse and more distinct, but gradually become less and less distinct (and more fine) which makes the objects appear to get further and further away.
What is Motion Parallax?
When Moving (Ex: In a Car) Far Objects look like there moving slower than
How do we percieve a 3-D world based on 2-D images on the retina?
Using the Binocular cues and Monocular Cues in the enviornment
What is David Marr’s Theory of Vision?
We Recognized objects by first getting a general understanding to a more detailed one in our brain
What is Recognition by component Theory (RBC)
Every object is just a combination of 36 basic geometrical shape
called “Geons”
What are the two approaches to perception?
Inferential and Ecological
