Frame-invariance
An object or property is frame-invariant if it does not depend on the frame of reference, i.e., the point from which it is observed or measured. It is frame-dependent if it is not frame-invariant. For example, the truth value of a mathematical statement is frame-invariant, whereas the beauty of a picture is frame-dependent. Similarly, the rest mass of a particle is frame-invariant, whereas its velocity is frame-dependent due to General Relativity.
The term frame-invariance is nonstandard in the philosophical discourse but is synonymous with the more commonly used concept of mind-independence. In this wiki, frame-invariance is preferred because it more naturally applies to concepts related to consciousness. For example, it is technically true to say that Valence is mind-independent since it is independent of which mind examines it, but since it is itself a property of a mind, this description sounds paradoxical. Using the term frame-invariance avoids this problem while conveying the same information.
