|Perception, philosophy: perceptions are conscious or unconscious processings of changes of state or events in the environment or within a living organism. Perceptions are happening in the present. Memories and imaginations are not perceptions. In language usage the expression of perception is used both for the process of perception and for the perceived. See also stimuli, sensations, sense perceptions, computation, memory, ideas._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

"Subliminal perception": (1960s) subliminal perception was controversial, asserted by advertising professionals. There is no evidence for them.
Nevertheless, subtle perception: when two objects are shown briefly at a precisely determined distance,...
...both objects can be seen, otherwise only one.
E.g. Question: what face have I already shown to you: here the answers were random.
On the other hand:
"Which face do you prefer?": Here the test persons chose the face, which they had previously "subliminally" seen.
Brain/Consciousness/Frith: Brain scanners showed that an object can cause a change in brain activity without the person being aware of it. (In the Amygdala).
Thesis: "Our brain does not tell us everything it knows."
Perception/Frith: Thesis: Perception is a fantasy which is in harmony with the world.
Blind spot/brain/perception/Frith: the brain invents something for the empty space.
E.g. The alphabet is presented very quickly. Then you are sure to have seen the letter A, even if the letter B has appeared instead._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
