Lecture 4 Flashcards
How does the brain nagivate our complex visual world?
- bottom up processing
- top down processing
Bottom up processing?
I am trying to understand what im looking at by actually seeing it
Top down processing?
We have previous expereince in the world, so it would influence how we see the world
What is Object Occulsion
- You are able to recignize what you know
- even when seeing something partially, thanks to past experience
viewpoint Invariance?
Same chair, but jsut from diffrent angles
What are the three theoritical viewpoints?
- Hemoltz’s theory of unconcious inference
2.The gestalt principle of organization - regularities of environment
Hemoltz’s theory of unconcious inference
Likelihod Principle
- Brain looks for what is more likley
The gestalt principle of organization
Principle of simplicity
- Things that look alike, the brain groups together
- finds the most simple explanation
regularities of environment
- Physical structure will have an influence of what we see
- uses built in assumption
like ames rom
Ames room
- trapazoid shaped room that makes ones person look tall, and the other short.
- people assume wall is normal and not deformed
Semantic regularities
- Things that look alike go together
- if you were to see an image of a kitchen, you will recall things that belong there quicker than objects that don’t belong
- Your brain says “based on my experiences “I’m more likley to see something”
cortical reorganization
You ability to move other fingers increase, becasue there is more brainpower going to other fingers.
Experience dependant plasticity
When you learn something new, such as playing a musical instrument or mastering a new language, your brain forms new connections between neurons.
- or even learning how to identify greebles, and process thme as faces
Interaction with Action:
If we were to drink coffee
- our brain has to see the cup
- reach for the cip
- grasp the cup with the right force
Parietal lobe goal?
- processes spatial and sensory information, helping you figure out where things are and how to interact with them.
- pushes info to temporal lobe
