The syntactic behaviour of human beings cannot be explained by analogical generalization on the basis of concrete exemplars: analogies in surface form are insufficient to account for human grammatical knowledge, because they fail to hold in situations where they should, and fail to extend in situations where they need to. [For Ben Ambridge's…

This commentary critiques Ambridge's radical exemplar model of language acquisition using research from the Longitudinal Study of Early Language, which has tracked the language development of 30+ children with Autism Spectrum Disorders (ASD) since 2002. This research has demonstrated that the children's capacity for abstraction at the grammatical…

The general purpose of this study is to increase, in a classroom environment, formal communication by using reading and writing. Our research focuses on reading as a means to develop the writing of a good précis, which in its turn contributes to improve: 1) memory, vocabulary and grammatical-syntactical structures, in brief, the organization of a…

In the past 15 years, a substantial body of evidence has confirmed that a powerful distributional learning mechanism is present in infants, children, adults and (at least to some degree) in nonhuman animals as well. The present article briefly reviews this literature and then examines some of the fundamental questions that must be addressed for…

Purpose: This lead article of the Clinical Forum addresses some of the gaps that exist between clinical practice and current knowledge about instructional factors that influence learning and language development. Method: Topics reviewed and discussed include principles of learning, generalization, treatment intensity, processing interventions,…

In this paper, we try to see how insights from morphology and grammaticalisation can be combined. Two approaches to the semantics of inflectional affixes are contrasted. According to one, affixes have no meaning, according to another, affixes have meaning just like lexical items. Given insights from grammaticalisation, a middle way, associated…

English-speakers' learning of a French vowel contrast (/schwa/-/slashed o/) was examined under six different stimulus conditions in which contrastive and noncontrastive stimulus dimensions were varied orthogonally to each other. The distribution of contrastive cues was varied across training conditions to create single prototype, variable far…

Rules, and exceptions to such rules, are ubiquitous in many domains, including language. Here we used simple artificial grammars to investigate the influence of 2 factors on the acquisition of rules and their exceptions, namely type frequency (the relative numbers of different exceptions to different regular items) and token frequency (the number…

According to the Longman Grammar of Spoken and Written English 1999 by Biber et al. (p. 266) generic article uses are more than twice as common in academic English than in conversation or fiction. This is an area that English for Academic Purpose (EPA) textbooks and teachers would need to target more than general English teaching. This paper is…

Complexity, accuracy, and fluency have proved useful measures of second language performance. The present article will re-examine these measures themselves, arguing that fluency needs to be rethought if it is to be measured effectively, and that the three general measures need to be supplemented by measures of lexical use. Building upon this…

Agrammatism is--among others, characterized by a deficit in producing grammatical structures. Of specific difficulty is the utilization of complex, non-canonical sentence structures (e.g. object-questions, passives, object-clefts). Several studies have documented positive effects when applying a specific treatment protocol in terms of increasingly…

Cognitive processes are often attributed to statistical or symbolic general-purpose mechanisms. Here we show that some spontaneous generalizations are driven by specialized, highly constrained symbolic operations. We explore how two types of artificial grammars are acquired, one based on repetitions and the other on characteristic relations…

This study examined the relationship between the metalinguistic reflections produced by French-speaking elementary school students and their actual learning of ESL. Using a before-after design, data was collected at the beginning (Time 1) and at the end (Time 2) of a 3-month period during which the participants kept a metalinguistic journal.…

Results of a seven-week sentence stimulation treatment on sentence production in an aphasic adult female with agrammatism indicated that treatment influenced description of test picture sets and that some generalization to other picture sets occurred. (Author/DB)

A line of reasoning used in recent research on language acquisition assumes that a child acquiring the language has only two reliable sources of information available about the target grammar: a set of grammatical principles and the primary data of the language spoken around him. A third kind of evidence, negative evidence, would be helpful but is…
