Cacciari: "Crossing the Sense in Metaphorical Language" (2008)

Cristina Cacciari's contribution to the Cambridge Handbook of Metaphor and Thought contains two relatively independent parts: First, a discussion of various attempts to describe and explain the phenomenon of cross-modal metaphor in language; and second, a fascinating summary of some of the things we know about (clinical) synaesthesia as of now.

She also provides some useful pointers to pre-1980 literature on metaphor and thought:

• Joseph M. Williams: "Synaesthetic adjectives: A possible law of semantic change." Language, 1976.
• George A. Miller and Philip Johnson-Laird: Language and perception. Harvard UP, 1976.
• Brenda E. F. Beck: "The metaphor as mediator between semantic and analogical modes of thought." Current Anthropology, 1978.
• Sandra Derrig: "Metaphor in the color lexicon." Papers from the Parasession on the Lexicon, the Chicago Linguistic Society, 1978.
• Lawrence E. Marks: The Unity of Senses: Interrelations Among the Modalities. Academic Press, 1978.
• Geoffrey Nunberg: "The non-uniqueness of semantic solutions: Polysemy." Linguistics and Philosophy, 1979.
• Stephen de Ullmann: "Romanticism and Synaesthesia: A Comparative Study of Sense Transfer in Keats and Byron." Publications of the Modern Language Association of America, 1945.

Something that might also be worth looking into is the anthology Cognition and Figurative Language (1980).
