This response argues against the proposal that novel utterances are formed by analogy with stored exemplars that are close in meaning. Strings of words that are similar in meaning or even identical can behave very differently once inserted into different syntactic environments. Furthermore, phrases with similar meanings but different underlying…

We present a neural network model of learning and processing the English past tense that is based on the notion that experience-dependent cortical development is a core aspect of cognitive development. During learning the model adds and removes units and connections to develop a task-specific final architecture. The model provides an integrated…

This article reexamines Bley-Vroman's original (1990) and evolved fundamental difference hypothesis that argues that differences in path and endstate of first language acquisition and adult foreign language learning result from differences in the acquisition procedure (i.e., language faculty and cognitive strategies, respectively). The evolved…

Clahsen and Felser (CF) have written a fairly comprehensive review of the current literature on on-line second language (L2) processing, presenting data from eye movement, self-paced reading, and event-related potential (ERP) studies with the aim of evidencing possible differences between native language (L1) and L2 processing. The thrust of the…

Clahsen and Felser (CF) have written a beautiful and important paper. I applaud their integrative empirical approach, and believe that their theoretical account is largely correct, if not in some of its specific claims, at least in its broader assumptions. CF directly compare their shallow structure hypothesis (SSH) with a model that my colleagues…

We join other responders in thanking Clahsen and Felser (CF) for pulling together these observations about the development of language processing. We are especially impressed by the generality and inclusiveness of CF's treatment of development in L1 and L2. Because most of their specifics concerned comprehension processes, our contribution will…

In their Keynote Article, Clahsen and Felser (CF) provide a detailed summary and comparison of grammatical processing in adult first language (L1) speakers, child L1 speakers, and second language (L2) speakers. CF conclude that child and adult L1 processing makes use of a continuous parsing mechanism, and that any differences found in processing…

The proposal by Clahsen and Felser (CF) has the potential of marking a turning point in second language (L2) acquisition research. Contrary to much L2 research to date, it suggests that some of the differences between native and (advanced) nonnative speakers may be at the level of grammatical processing, rather than grammatical representations.…

In this article, the authors lay out an impressive body of evidence that supports two main claims. First, they favor the continuity hypothesis, according to which children's parsing mechanisms are essentially the same as adults'. Parsing strategies change little over time, and those changes that occur are attributed to differences in lexical…

Clahsen and Felser (CF) offer a novel explanation for the qualitative differences in language processing often observed between adult first language (L1) speakers and second language (L2) learners. They argue that, although L2 learners are successful in drawing on lexical, morphological, and pragmatic sources of information, they underutilize…

Clahsen and Felser's article (CF) is an important contribution to the field of psycholinguistics in several respects. First, it draws attention to the importance of a better understanding of the processing mechanisms utilized by child and adult language learners. Differences in these mechanisms may be responsible for the final outcome of the…

Outlines a theoretical perspective to account for how the writing that adults produce and use appears to get done, what it seems to be, and how it apparently functions in contemporary culture. Argues for a conceptualization of writing that is predicated on broader and more realistic understandings of text and writing than have generally informed…

Clahsen and Felser (CF) deserve praise for their superlative synthesis of literature relating to grammatical processing, as well as for their original contributions to this area of research. CF "explore the idea that there might be fundamental differences between child L1 and adult L2 processing." The researchers present evidence that adult second…

This paper does a fine job of advancing discussion concerning a question that is indeed quite underrepresented in the literature, that is, how language learners comprehend and produce language in real time. The paper is firmly rooted in the dual mechanism approach to language processing and takes as its starting point the assumption that normal…

Clahsen and Felser (CF) analyze the performance of monolingual children and adult second language (L2) learners in off-line and on-line tasks and compare their performance with that of adult monolinguals. They conclude that child first language (L1) processing is basically the same as adult L1 processing (the contiguity assumption), with…
