The theta-criterion (also named θ-criterion) is a constraint on x-bar theory that was first proposed by Noam Chomsky as a rule within the system of principles of the government and binding theory, called theta-theory (θ-theory). As theta-theory is concerned with the distribution and assignment of theta-roles (a.k.a. thematic roles), the theta ...
In government and binding theory this is known as proper government. Proper government occurs either if the empty position is governed by a lexical category (especially if it is not a subject) (theta-government) or if it is coindexed with a maximal projection which governs it (antecedent-government). The ECP has been revised many times and is ...
Government and binding (GB, GBT) is a theory of syntax and a phrase structure grammar in the tradition of transformational grammar developed principally by Noam Chomsky in the 1980s. [ 1 ] [ 2 ] [ 3 ] This theory is a radical revision of his earlier theories [ 4 ] [ 5 ] [ 6 ] and was later revised in The Minimalist Program (1995) [ 7 ] and ...
Neutral theory – Theory of evolution by changes at the molecular level; Shifting balance theory – One version of the theory of evolution; Price equation – Description of how a trait or gene changes in frequency over time; Coefficient of relationship – Measure of biological relationship between individuals
The concept was first introduced by S. Pancharatnam [1] as geometric phase and later elaborately explained and popularized by Michael Berry in a paper published in 1984 [2] emphasizing how geometric phases provide a powerful unifying concept in several branches of classical and quantum physics.
In (1), the constituent (whom) and its trace (t) are said to form a "chain". In syntax, Move α is the most general formulation of possible movement permitted by a rule. More specific rules include Move NP and Move wh, which in turn are more general than specific transformations such as those involved in passivization. [ 1 ]
Darwin's theory of evolution by natural selection is the only scientific explanation for why an animal's behaviour is usually well adapted for survival and reproduction in its environment. However, claiming that a particular mechanism is well suited to the present environment is different from claiming that this mechanism was selected for in ...
The local domain is the smallest XP containing a DP, in order to satisfy Binding Theory, the DP must c-command the anaphor and have a subject. [1] Therefore, the antecedent must be in the same clause that contains the anaphor if it is to abide to Binding Theory. An anaphor is considered to be free when it is not c-commanded or co-indexed.
