Examines the central characteristics of interlanguages that distinguish them from all other natural language systems. It is proposed that, since permeability presupposes an interlanguage norm which is relatively stable, we are forced to gather enough data to establish the overall level of linguistic competence of the learner.

The nature and purpose of parental speech in the language acquisition process of the young child is explored in this article. The effect of the quality and quantity of parental speech on the child's language development and linguistic interactions among language-delayed children are discussed. (DF)

Evidence is presented to support the hypothesis that informal and formal environments contribute to different aspects of second language competence, the former affecting acquired competence and the latter affecting learned competence. Data is presented that suggests that the classroom can be used simultaneously as a formal and informal linguistic…

This study investigates the theoretical plausibility and empirical validity of the assumption that all performance in a foreign language can be traced back to a single factor, the general language ability factor. The theoretical background of this hypothesis is reviewed in detail. The concept of a unitary linguistic competence, interpreted as an…

Earlier version of this paper was read at the Second International Congress of Applied Linguistics, Cambridge University, Cambridge, England, in September 1969. (VM)

Reports on an experiment designed to reveal how the learner's passive foreign language vocabulary is built up, what role the context plays, what kinds of learning strategies are involved, and whether a false competence results from these strategies. (IFS/WGA)

Reviews the relationship between linguistic theory and language teaching. The suggestion is made that a teaching approach should not be based completely on one theory, be it structuralist or generative. In selecting an approach, the teacher should draw selectively on various linguistic theories, on educational psychology, and on practical…

It is argued that three misconceptions about language learning have limited the utility of performance objectives in individualized second language instruction. These misconceptions--confusion between competence and performance, inadequate identification of linguistic elements, and assumption that linguistic elements correspond to learning…

Discusses the consensus among language teachers that the teaching of grammar helps second language learners develop linguistic competence as part of communicative competence. The article argues that pedagogical grammar can be made less formal by keeping metalinguistic terms, concepts, and analysis at a minimal level. (45 references) (Author/CK)

It has been claimed that error analysis (EA) has two broad aims and two levels of application: pedagogical (relevant to syllabus design and second language teaching) and psycholinguistic (relevant to language learning studies). At the moment, EA's pedagogical claims are stronger than its psycholinguistic ones. In its early days, EA defined its…

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…

Three hypotheses are examined in relation to English copula and negative utterances produced by three native Spanish speakers. The hypotheses are interference, interlanguage and L1=L2, which states that acquisition of a language by second language learners will parallel acquisiton of the same language by first language learners. The results of the…

One of the several causal mechanisms for errors made by adult second language learners is interference from the native language. This paper attempts to account for the cognitive nature of interference by proposing two psycholinguistically based principles that will explain various types of production and perception errors made of second language…

This is a study of the kinds of processes involved in learning the meaning of individual lexical items, and in particular how the acquisition of lexical meaning is related to the cognitive structuring of events on the one hand and the ability to produce syntactic paraphrases of a word's meaning and other related constructions on the other. It is…

In a recent paper (1977) Levenston and Blum suggested that lexical simplification operates according to universal principles, and that these derive from the individual's semantic competence in his mother tongue. This paper examines the validity of this suggestion by means of a comparative study of lexical simplification in three different…
