This provocative article raises many important issues that need to be addressed and in so doing will advance the fields of second language (L2) and third language (L3) acquisition in several important ways. Fundamental questions concerning multilingual development persist especially with respect to the role of Universal Grammar in this language…

In her keynote article advocating the Linguistic Proximity Model for third language (L3) acquisition, Westergaard (2021) presents several arguments against 'copying and restructuring' in nonnative language acquisition, mechanisms central to Schwartz and Sprouse's (1996) Full Transfer/Full Access model of second language (L2) acquisition. In this…

This commentary discusses the recent keynote article in "Second Language Research" by Westergaard (2021), which extends the Micro-cue Model to second language (L2) and third language (L3) acquisition. The commentary comments on such questions as: What makes a given property easy or hard to acquire? How do learners determine similarity?…

In this commentary, I suggest that it may be helpful to think about the formidable problem space that Westergaard's (2021) Linguistic Proximity Model seeks to address at the three levels of analysis that Marr (1982) famously proposed are needed to understand any complex cognitive system. I argue that at the computational level of analysis, where…

This paper presents an analysis and comparison of the projection of Chinese "shen" and English "deep" from the spatial domain to other domains of time, sense, emotion, behavior, and society from a cognitive perspective by using the comparative and contrastive method, explaining the universality and differences of SHEN and DEEP…

In this article, I argue that first language (L1), second language (L2) and third language (L3) acquisition are fundamentally the same process, based on learning by parsing. Both child and adult learners are sensitive to fine linguistic distinctions, and language development takes place in small steps. While the bulk of the article focuses on…

Second language acquisition has been observed to be variable in its outcome such that, unlike native speakers, all second language learners do not achieve total success. Second language acquisition is made of macro and micro processes. External and internal (e.g., age, individual differences) factors are assumed to affect language processing in…

The author considers controversial psycholinguistic problems in the study of first and second language acquisition, raising such questions as whether all children learn language in the same way, and whether all languages are learned in the same way. Her observations, based partially on observing her own bilingual child, suggest that the cenematic…

Summarizes the Sapir-Whorf Hypothesis on language and thought process, along with several critical viewpoints. The writings of Koschmieder, Gipper, and Lenneberg, as well as psychological and linguistic aspects of experiments on color differentiation and conditioned response, are discussed. (Text is in German.) (DH)

In one experiment, children from 5 to 10 years of age played with puppets and responded to questions concerning the acquisition of one particular linguistic structure by children; in another series of experiments, both children and adults responded to questions regarding nonsense words in differentiating contexts--the focus of the discussion…

This article presents the theoretical and practical implications of a psycholinguistic model which exploits students' knowledge about language and which incorporates attitudinal variables into a strategy for teaching foreign language grammar. (DB)

A definition of bilingualism can include speakers of different languages as well as those who speak several dialects or several sub-varieties of dialects in the same language. Most speakers are able to practice code-switching, whether it is from language to language or dialect to dialect, and the processes involved in such a capability may be the…

Human capacity for language acquisition is not strictly compartmentalized, with one acquisitional mechanism for the native language and others totally unrelated to it; rather, it consists of a unified mechanism flexible enough to handle various differences in external settings. This learning system operates on the formal properties of the…

Some aspects of a theory of grammar are presented which derive from a formal theory of language acquisition. One aspect of the theory is a universal constraint on analyzability known as the Freezing Principle, which supplants a variety of constraints proposed in the literature. A second aspect of the theory is the Invariance Principle, a…

If the question of what it is that is innate is simply left as some kind of human learning potential, this position, representative of the nativist philosophy, does not differ radically from that of behaviorists. The latter position holds that a human being starts out with a mind which is basically empty and receptive to, subject to, and the…
