|Sensory Impressions, philosophy: the concept of impression is intended to serve as a boundary to the concept of perception. It places the weight on information not yet processed on the side of the receiving subject. Perception, on the other hand, refers to prepared information, which allows classification, storage and evaluation. See also stimuli, perception, sensations, input, information, qualia._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Chris Frith on Sensory Impressions - Dictionary of Arguments
Sensory Impression/sense-perception/meaning/Frith: thesis: we are not the slaves of our senses.
Experience/Frith: experience is not constantly dominated by sensory signals. We could not have hallucinations, but it would not be a good idea.
Problem: sensory signals are too unreliable. We should not be slaves of our senses. This only occurs in brain damage. For example, when these people see a glass, they have to drink from it.
Fantasy: controlled fantasy saves the brain from the tyranny of the environment.
1. How do we know that the model of the world that our brain designs is the right one?
Solution: this is not a real problem: the model does not have to be the right one, it just has to work so that we can influence the world.
2. How does the brain know whether I actually see a face or just imagine one?
Imagination: in a pure representation there are no sensory signals, and thus also no possible error message.
Reality/Frith: reality is always unexpected.
Imagination/Frith: imagination is boring in the long run, e.g. there is no deception in the imagination, an imagined necker cube never veers round.
Creativity/Frith: we create nothing in our head alone.
Solution: first by doodling, writing, sketching, etc.: we are shifting to the outside._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
