Abstract : The report consists of four parts: (1) Cross-Over Phenomena is a study in the grammar of coreference. A wide variety of evidence is presented which shows that the distribution of nominal expressions in English sentences is subject to previously unsuspected constraints involving coreference. Principles are suggested which explain a large number of such cases in terms of general restrictions on classes of transformations that move nominal expressions. (2) Dependency Structures and Transformational Rules explores the use of a dependency grammar as the categorial component of a transformational grammar. Potential advantages of such a choice include explicit marking of phrase heads, which may govern the applicability of certain transformations, and elimination of the need for 'tree-pruning.' (3) Case, Category, and Configuration reviews recent transformational work on case and proposes an abstract form for the base component as a framework for representing pertinent aspects of case relationships. (4) A Survey of Some Recent Work in Psycholinguistics discusses recent research on memory and perception of sentences, considers its possible implications for the design of recognition procedures and man-computer interaction languages, and recommends some future lines of investigation.
