If by “discourse analysis frameworks” [1] you are referring to “Metaphor Identification Procedure”, and by “cognitive linguistic frameworks” [2] to “Image Schema”, then I suggest the answer lies in between…. ;^)
For me the real question is… what are the mechanics of converting words into images, and images into words in the human brain? I tend to think of this mechanism in terms of a “clutch”, or transducer of some kind, and can refer you to my draft webpages on the role of Computational Metaphorics [3] in Computational Dreaming [4].
