A major open question in natural language research is the role of communicative efficiency in the origin and on-line processing of language structures. Here, we use word pairs like "chimp/chimpanzee", which differ in length but have nearly identical meanings, to investigate the communicative properties of lexical systems and the communicative…

A robust result in research on the production of grammatical agreement is that speakers are more likely to produce an erroneous verb with phrases such as "the key to the cabinets", with a singular noun followed by a plural one, than with phrases such as "the keys to the cabinet", where a plural noun is followed by a singular. These asymmetries are…

In the present study we analyzed the processing of grammatically anomalous sentences like "*The famous dancer were nervously preparing herself/themselves to face the crowd.", which contains two anomalies, one early and one late. We investigated how processing of the later anomaly (at the pronoun "herself" or…

We present four experiments on the interpretation of pronouns and reflexives in picture noun phrases with and without possessors (e.g. "Andrew's picture of him/himself, the picture of him/himself"). The experiments (two off-line studies and two visual-world eye-tracking experiments) investigate how syntactic and semantic factors guide the…

Are speakers equipped with preferences concerning grammatical structures that are absent in their language? We examine this question by investigating the sensitivity of English speakers to the sonority of onset clusters. Linguistic research suggests that certain onset clusters are universally preferred (e.g., "bd" is greater than "lb"). We…

Everyday speech is littered with disfluency, often correlated with the production of less predictable words (e.g., Beattie & Butterworth [Beattie, G., & Butterworth, B. (1979). Contextual probability and word frequency as determinants of pauses in spontaneous speech. "Language and Speech, 22," 201-211.]). But what are the effects of disfluency on…

Presents a computational study of children's acquisition of word-to-meaning mappings, approximates this task as a mathematical problem, and presents an algorithm for solving the problem, illustrating the algorithm's operation on a small example. Notes that computational simulations demonstrated the robustness of the algorithm and illustrated how…

In a recent "Cognition" paper ("Cognition" 85 (2002) B21), Bornkessel, Schlesewsky, and Friederici report ERP data that they claim "show that online processing difficulties induced by word order variations in German cannot be attributed to the relative infrequency of the constructions in question, but rather appear to reflect the application of…

Recent research in semantics and pragmatics has revived the debate about whether there are two cognitively distinct categories of conversational implicatures: generalised and particularised. Generalised conversational implicatures are so-called because they seem to arise more or less independently of contextual support. Particularised implicatures…

Explains distributional regularity (DR), an intuition that sound sequences occurring frequently and in multiple contexts are candidates for the lexicon. Describes study that proposed hypotheses about children's segmenting sounds using DR functions, exploiting phonotactic constraints on pronunciation, and learning word-boundary clusters. Details…

In some psycholinguistic models, processing is characterized by generation of multiple outputs using information from higher processing levels. Such models are considered autonomous in word recognition domain but interactive in sentence processing domain. This confusion arises not from differences between lexical and syntactic processing, but from…

Five experiments support the argument that symmetry predication a is property of lexical items and has no special syntax; structural positioning of noun phrases in symmetricals-containing sentences sets their status as figure and ground or variant and referent, even for nonsensical nouns; and symmetrical predicate behavior varies as a function of…

We show that Kempen and Harbusch's ("Cognition" (2003) "this issue") arguments against our claims cannot be upheld. On the one hand, their alternative account of our data that is based on the availability of constructions with object-experiencer verbs is not compatible with the literature on the processing of these types of sentences in German.…

Examined capacity of 4-month olds to identify their maternal language (Catalan or Spanish) when phonologically similar languages are contrasted. Compared infants from monolingual and bilingual environments to analyze whether differences in linguistic background affect this behavioral response. Found that language discrimination is already possible…

Three experiments investigated the nature of productive forward linking (from semantics to syntax) and productive reverse linking (from syntax to semantics) in language-impaired children. Found that the normally developing control subjects showed a good use of productive forward and reverse linking, whereas the language-impaired subjects…
