Islands and Barriers To Movement
Since it was first proposed, the theory of syntactic movement yielded a new field of research aiming at providing the filters that block certain types of movement, also called locality theory. Locality theory is interested in discerning the islands and barriers to movement. It strives to identify the categories and constellations that block movement from occurring. In other words, one wants to understand why certain attempts at movement fail, e.g.
-
- a. You think that Mary visited Peter before calling Fred.
- b. *Who do you think that Mary visited Peter before calling ___?
-
- a. Your picture of Fred was funny.
- b. *Who was your picture of ___ funny?
-
- a. You like Bill's ideas.
- b. *Whose do you like ___ ideas?
The b-sentences are now all disallowed due to locality constraints on movement. Adjuncts and subjects are islands that block movement, and left branches in NPs are barriers that prevent pre-noun modifiers from being extracted out of NPs.

Famous quotes containing the words islands, barriers and/or movement:
“Consider the islands bearing the names of all the saints, bristling with forts like chestnut-burs, or Echinidæ, yet the police will not let a couple of Irishmen have a private sparring- match on one of them, as it is a government monopoly; all the great seaports are in a boxing attitude, and you must sail prudently between two tiers of stony knuckles before you come to feel the warmth of their breasts.”
—Henry David Thoreau (1817–1862)
“The barriers of conventionality have been raised so high, and so strangely cemented by long existence, that the only hope of overthrowing them exists in the union of numbers linked together by common opinion and effort ... the united watchword of thousands would strike at the foundation of the false system and annihilate it.”
—Mme. Ellen Louise Demorest 1824–1898, U.S. women’s magazine editor and woman’s club movement pioneer. Demorest’s Illustrated Monthly and Mirror of Fashions, p. 203 (January 1870)
“Prostration is our natural position. A wormlike movement from a spot of sunlight to a spot of shade, and back, is the type of movement that is natural to men.”
—Wyndham Lewis (1882–1957)
