PSY 357 Lecture Notes - Lecture 3: Ray Jackendoff, Transformational Grammar, Surface Roughness
Document Summary
Now that we"ve figured out how to diagram a tree structure, let"s completely change the approach. The order in which the words appear in a given sentence. But chomsky (1957) pointed out that looking at surface structure alone is not descriptively adequate. Postulated existence of distinction between deep structure and surface structure. Surface structure: roughly, the final order of words we actually see. Deep structure: the hidden, underlying structure of a sentence from which meaning is computed. Surface structure alone doesn"t explain why two sentences with different structures might mean the exact same thing. Nor does it explain why two sentences with similar word orders can take on very different general meanings. Pl 1/21 2: transformational rules, a few assumptions of transformational grammar. Phrase structure rules and lexical insertion rules are used to generate deep structure. Transformations operate on the deep structure to produce a surface structure.
