The term "recursion" is used in at least four distinct theoretical senses within cognitive science. Some of these senses in turn relate to the different levels of analysis described by David Marr some 20 years ago; namely, the underlying competence capacity (the "computational" level), the performance operations used in real-time processing (the…

Focusing on children's production of the dative alternation in English, we examine whether children's choices are influenced by the same factors that influence adults' choices, and whether, like adults, they are sensitive to multiple factors simultaneously. We do so by using mixed-effect regression models to analyse child and child-directed…

Hungarian is a language with morphological case marking and relatively free word order. These typological characteristics make it a good ground for testing the crosslinguistic validity of theories on processing sentences with relative clauses. Our study focused on effects of structural factors and processing capacity. We tested 43 typically…

Eye fixation durations during normal reading correlate with processing difficulty, but the specific cognitive mechanisms reflected in these measures are not well understood. This study finds support in German readers' eye fixations for two distinct difficulty metrics: surprisal, which reflects the change in probabilities across syntactic analyses…

Semantic roles are a critical aspect of linguistic knowledge because they indicate the relations of the participants in an event to the main predicate. Experimental studies on children and adults show that both groups use associations between general semantic roles such as Agent and Theme, and grammatical positions such as Subject and Object, even…

We investigate linguistic relativity effects by examining whether the grammatical count/mass distinction in English affects English speakers' semantic representations of noun referents, as compared with those of Japanese speakers, whose language does not grammatically distinguish nouns for countability. We used two tasks which are sensitive to…

Demonstrates how the definition of "simple attachment" and "tree lowering," operations related to the grammatical composition operations of "substitution" and "adjunction" in the Tree Adjoining Grammar formalism, yields a parser more constrained than previous description theory based models. The article…

Describes language acquisition processes occurring in a community of interacting agents, in which coordination of joint attention leads to the development of structures, internal and external, that support organized behavior. It is argued that the simulation model demonstrates the plausibility of propositions arising from such processes, and that…

Two studies are reported in which the following theory is tested: the agrammatic sentence form that is observed in the spontaneous speech of Broca's aphasics is attributable to the selection of elliptical syntactic structures in which the slots for many of the closed-class words that appear in complete sentences are lacking. (54 references)…

Notes that in linguistic theory, phenomena previously handled by a separate grammatical component have been moved into the lexicon and that in some theories, the contrast between grammar and the lexicon has vanished. Concludes that the case for a modular distinction between grammar and the lexicon has been overstated and that the evidence to date…

Provides evidence that sentence processing does not make use of grammatical theories with empty categories. A linguistic account is provided of unbounded dependencies that do not use empty categories and can serve as the basis of a processing model. It is concluded that empty categories are not psychologically real. (28 references) (JL)

Using the speeded-grammaticality judgment task, shows that factors that regulate garden path strength in ambiguous sentences also have an influence on processing of corresponding ungrammatical sentences in that they determine how reliably the ungrammaticality is detected. Argues that this processing correlation provides evidence for serial parsing…

Evaluates the input-processing, deficit/single system and the grammar-specific deficit/dual system models to account for past tense formation in impaired and normal language development. Investigated regular and irregular past tense formation of 60 real and novel regular and irregular verbs in grammatical specifically language impaired (G)-SLI…

Two series of experiments investigate two hypotheses that may explain a conflict regarding pronomial reference. The hypothesis accepted is that the use of the gender cue is under the reader's strategic control; the hypothesis rejected is that implicit causality and gender cue interact differently with the complexity of the inference needed to link…

Three experiments are reported on the interpretation of conceptual anaphors, defined as those that do not have an explicit linguistic antecedent but one constructed from text. Two experiments showed that conceptual anaphors are quite easily understood but are processed with difficulty; the third one showed mixed results. (three references)…
