In her Keynote Article, Paradis discusses the role of the interface between bilingual development and specific language impairment (SLI) on two different levels. On the level of theoretical explanations of SLI, Paradis asks how domain general versus domain-specific perspectives on SLI can account for bilingual SLI, as well as what bilingual SLI…

Much research has posited a developmental sequence approach in second-language acquisition. This study reexamines the original social-psychological research upon which the multidimensional model is based and shows that it is incorrect because of faulty analysis. It also examines the limited applicability/generalizability of the developmental…

Addresses the relationship in second language acquisition (SLA) research between theory and data. Suggests a potential problem for the field of SLA; a lessening rigor in data analysis where theory moves more into focus. Documents how the problem manifests itself in a specific area of research in SLA--syntax and morphology--then discusses possible…

Several theories on bilingualism are studied and compared. (PP)

Examines the relationship between language universals and language acquisition, comparing data from studies on first and second language acquisition and universals of relative clause formation. It is concluded that second language acquisition data provide a clearer window for the investigation and verification of language universals than first…

The authors respond to comments on their article, "Back Channels Revisited." The current state of the art in acknowledgement token research is outlined with particular reference to the turn-initial token "yeah." Contrastive uses of acknowledgement tokens are described. (20 references) (LB)

Drummond and Hopper's article in this issue, "Back Channels Revisited," is argued to have decontextualized Jefferson's acknowledgement token phenomenon. The need for careful coding protocols for research on conversational practices is discussed. (eight references) (LB)

This paper reviews work done since January 1972 in children's language acquisition and development. It is divided into the following sections: (1) a brief summary of descriptive studies of adult and child speech, (2) a review of the results of three types of manipulative studies, and (3) a discussion of J. Gruber's interpretation of early…

Discusses arguments that support the position regarding the distribution of non-grammatical markings of negation and of "wh"-scope and emphasizes the importance of looking for deep unifying principles in cross-modal studies of American Sign Language in order to further understanding of Universal Grammar.

The construction of general linguistic theories is subject to errors of fact and perspective. The theoretical linguist is inclined by the nature of his work to fall into such errors because he/she is obliged to generalize about many languages on the basis of research done in one or a few. The scope of this task inevitably leads to a failure to…

Reviews the comments of Goldsmith on Firthian Prosodic Analysis (FPA) and its relationship with Autosegmental Phonology (AP). It is argued that AP has maintained the insights of FP while providing additional analytic possibilities. The authors examine Goldsmith's misinterpretations and clarifies the characteristics of FPA.

This article reviews basic issues of theory and method in qualitative research approaches to applied linguistics research, focusing on the ways in which qualitative research can contribute to an understanding of second-language acquisition and use. (83 references) (MDM)

The acquisition of German in three adult Poles over a three-year period is examined based on an acquisition profile of each person that specified the sequences in acquisition. The findings suggest that cognitive factors must be considered to explain the varying degree of success in the acquisition process. (40 references) (Author/LB)

Examines evidence offered to support the idea of a sensitive period for second language acquisition. Findings indicate that there is insufficient evidence to accept the claim that mastery of a second language is determined wholly, or even primarily, by maturational factors.
