It is suggested that the strengths and weaknesses of current theories of metaphor are dependent on the type of metaphor being examined. Recent research in the possible functions of metaphor is reviewed, including evidence that metaphors function as schemas and experimental evidence that metaphor-based schemas can affect the structure of readers' text representations.(LLBA 1996, vol. 30, n. 1) Special issue edited by Roger J.
