 This sort of analysis of experiences is sometimes known as adverbialism in the literature because in perceiving a red object one is said to be in a state of perceiving something “red-ly.” The theoretical import of this way of talking is that perceiving something that is red is a manner of perceiving that object that would be distinct from the manner of perceiving it if the object were blue, in which case one would be perceiving it “blue-ly.” Similarly when one hallucinates a red object, there is only one object, the perceiver who is sensing in a certain manner, namely, red-ly. In other words, ‘red’ is said to qualify not a private object but rather a state or activity of a person, that state being a manner of perceiving or sensing physical objects that are  red.[13]  For our purposes, keeping up with the general naturalistic motivation behind developing direct realist views, we can take adverbialism as an attempt to get rid of mysterious mental objects or qualities in favor of metaphysically less costly states or activities of persons or manners of perceiving that qualify persons qua subjects of experience. So a pain experience, for a direct realist, is a specific manner in which tissue damage is (somatosensorially) perceived in a bodily region. When we report pain, we report the occurrence of experiences understood this way — adverbially.
