You can never have all the information of reality
We can only have access to a limited subset of reality
We have limited
- sensitivity of our sensory mechanisms
- attentional capacity, more cognitive load = more error
- perception is the moment of initial detection
- you act not on the actual object but your internal representation of the object and act
on it
- anxiety or depression can involve reality but also involve very little of reality based on
the persons internal processing
Perception is a process of creative story-telling and inference making... Based on 'a true
story'
Speed-accuracy trade off-
- this is holy functional.. Most of the time
- you never actually know, you are always just guessing
Remember though, this means that we are not directly interacting with reality, but rather,
we are creating a fiction about reality and interacting with this fiction
- think of the difference between the character in a story and the observer in the story

Document Summary
You can never have all the information of reality. We can only have access to a limited subset of reality. Attentional capacity, more cognitive load = more error. Perception is the moment of initial detection. You act not on the actual object but your internal representation of the object and act on it. Anxiety or depression can involve reality but also involve very little of reality based on the persons internal processing. Perception is a process of creative story-telling and inference making based on "a true story" You never actually know, you are always just guessing. Remember though, this means that we are not directly interacting with reality, but rather, we are creating a ction about reality and interacting with this ction. Think of the difference between the character in a story and the observer in the story. Reality is a story,told to us by our brains. We don"t live in the real world, but a constructed world.
