Is there an ideal time window for language acquisition after which nativelike representation and processing are unattainable? Although this question has been heavily debated, no consensus has been reached. Here, we present evidence for a sensitive period in language development and show that it is specific to grammar. We conducted a masked priming…

The ability to acquire language is a critical part of human development. Yet there is no consensus on how the skill emerges in early development. Does it constitute an innately-specified, language-processing module or is it acquired progressively? One of Annette Karmiloff-Smith's (1938-2016) key contributions to developmental science addresses…

In an event-related potential (ERP) study we investigated the role of age of acquisition (AoA) on the use of second language rhythmic properties during syntactic ambiguity resolution. Syntactically ambiguous sentences embedded in rhythmically regular and irregular contexts were presented to Turkish early and late second language (L2) learners of…

This article tests a prediction made by Processability Theory (Pienemann, 1998; 2005) that morphological acquisition is the driving force in English as a second language (ESL) development. It first outlines the model of psycholinguistic processing assumed by Processability Theory and shows how stages fall out from it. It then presents the…

P. Bloom's (1990) data on subject omission are often taken as strong support for the view that child language can be explained in terms of full competence coupled with processing limitations in production. This paper examines whether processing limitations in learning may provide a more parsimonious explanation of the data without the need to…

References to developmental stages and continua seem to be part and parcel of investigations into the acquisition of new grammars. Nonetheless, there seems to be an equivocation in the literature about which is actually the most helpful way of explaining how learner grammars evolve through time. Some see development essentially as gradual growth…

Hudson addressed two issues on second-language acquisition: the validity of the multidimensional model and the application of developmental sequence findings to assessment and pedagogy. This response suggests that his lines of argument are based on serious conceptual flaws. (Contains 37 references.) (LB)

Presents data on the past and present state of research on the interlanguage hypothesis, with specific attention to its extension to children. Outlines a dual approach to developing a theory of second language acquisition--a macrobehavioral approach and a neurofunctional approach. Finally, problems for the interlanguage hypothesis are discussed.…

Augments Michael Studdert-Kennedy's state-of-the-art report on speech perception research (EJ 227 656) with comments on categorical perception of speech and nonspeech stimuli, speech perception in context, the role of prosody, and development/impairments of speech perception. Includes a summary of a discussion on speech perception research. (RL)

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…

Folk tales were read to 32 kindergarten children of varying levels of language ability, as measured by the language scale of the Metropolitan Readiness Test. Recall protocols were parsed into the categories described by N. L. Stein and C. G. Glenn. Low ability children were found to be less likely to recall details of "internal plan" and…

Describes a study which sought to determine the developmental stage at which children begin to differentiate specific and neutral contingent queries. The study manipulated the familiarity of the adult listener by having each of the 22 children interact both with the mother and with an unfamiliar adult experimenter. (SED)

Delineates five developmental listening comprehension stages second language learners pass through: (1) streams of sound, with no comprehension; (2) word recognition within the stream; (3) phrase/formula recognition; (4) clause/sentence recognition; and (5) extended speech recognition, or general comprehension. The discussion illustrates the…

This study examined the effects of certain contextual linguistic variables on the logical performance of subjects in grades 4, 6, and 12 of selected British Columbia schools as well as some theoretical problems underlying assessment of the development of logical abilities. The task consisted of 27 syllogistic problems based upon the information…

Interactions between metaphor comprehension and level of operational thought were examined to determine what advantages individuals at the formal operational level had in natural language tasks such as the understanding of figurative language. After 30 undergraduate students were classified as either late concrete, early formal, or late formal…
