This dissertation presents a series of case studies concerned with whether the signal in a given set of measurements that we take in the course of linguistic inquiry reflects grammatical competence or performance factors. We know that performance and competence do not always covary, yet it is not uncommon to assume that measurements that we take…

The second language (L2) acquisition of tense, aspect, and mood/modality (TAM) has been widely explored as it holds the promise of a better understanding of the L2 learners' linguistic competences, particularly semantically and morpho-syntactically. This study focuses on the acquisition of the subjunctive mood by L1 English learners of L2 French…

The current study tests the Interface Hypothesis through forward and backward anaphora in complex sentences with temporal subordinate clauses in highly proficient English-speaking learners' second-language (L2) Chinese. Forward anaphora is involved when the overt pronoun "ta" "he/she" or a null element appears in the subject…

One of the intricate properties of second language acquisition is that some types of grammatical feature appear to be acquired easily and in a native-like way, while others remain persistently difficult. There is much evidence related to the issue in the current empirical studies, and the issue raises an important explanatory problem for a theory…

In the 1980s, researchers in child language devised several new experimental techniques to assess children's emerging linguistic competence. Innovations in methodology were needed to bridge the apparent gap between the expectation of rapid language acquisition, based on linguistic theory, and the protracted acquisition that was being witnessed…

The author endeavors to penetrate the "mists o f mentalistic myth" which enshroud the "very real, solid, and substantial results of generative or transformational linguistics." In attempting to clarify and clear up misunderstandings about theories of grammar as put forth by Chomsky (whose practice, the author feels, is "superior to his description…

Discusses the interaction of metaphor and idiom and the problems this poses for linguistic theory. (AM)

In this paper the author examines the "encoding-decoding" model of speaking and understanding English. He reviews in detail an objection to the model: that it was specifically designed with a view to incorporating linguistic theories, such as syntax, into it. As a result, what it more or or less accurately represents is the relation…

An analysis of sentence grammar is made to show that the ability to produce coherent texts emerges slowly and late in linguistic and cognitive development. (HP)

Examined parental speech data demonstrating that linguistic input to children does not contain sufficient information to support unaided learning of the pronoun "one." Examined 18-month-olds' interpretation of sentences with a "one" substitution. Found that 18-month-olds have command of the syntax of "one." Because…

In a study extending and refining Carol Chomsky's research, 48 Arabic speaking children aged six, eight, and ten were tested for their comprehension of imperatives using the complement-requiring verbs Ask, Tell, and Promise. Clear support for children's overgeneralization of the minimal distance principle was found only with Promise constructions.…
