In the experiments outlined in this article, the authors investigate lexical access processes in language production. In their earlier work, T. Pechmann and D. Zerbst (2002) reported evidence for grammatical category constraints in a picture-word interference task. Although grammatical category information was not activated when subjects produced…

In many languages, the production of noun phrases requires the selection of gender-marked elements like determiners or inflectional suffixes. There is a recent debate as to whether the selection of freestanding gender-marked elements, such as determiners, follows the same processing mechanisms as the selection of bound gender-marked morphemes,…

Two studies addressed the relative strengths of object kind bias and syntactic knowledge in 2-year-olds' inductions of word meaning. The study looked at children's interpretations of novel proper names for familiar and unfamiliar objects. In each study, 10 children were assigned to each of 2 conditions (familiar and unfamiliar) and shown 2 cats…

Discusses two auditory comprehension studies that investigated the role of focus, as conveyed by a pitch accent, in the comprehension of relative clauses preceded by a complex noun phrase. Findings include focus attracts modifiers, and pitch accents for new phrases differ acoustically from pitch accents for contrastive phrases. (46 references)…

Examined 2-year-olds' comprehension and production of novel nouns, verbs, or actions at 3 intervals after training conducted in massed or distributed exposures. Found that for comprehension, children learned all item types in all training conditions at all retention intervals. Production was better for nonverbal actions than for either word type…

In 4 experiments the authors used a variant of the picture-word interference paradigm to investigate whether there is a temporal overlap in the activation of words during sentence production and whether there is a flow of semantic and phonological information between them. Experiments 1 and 2 demonstrate that 2 semantically related nouns produce…

This paper offers evidence for the Isomorphic Mapping Hypothesis, which holds that individuals with agrammatic aphasia tend to have difficulty comprehending sentences in which the order of NPs is not aligned with the structure of the corresponding event. We begin by identifying a set of constructions in English and Korean for which the IMH makes…

A self-paced reading experiment investigated processing of sentences containing a noun-phrase that could temporarily be mistaken as the direct-object argument of a verb in a subordinate clause but actually constituted the syntactic subject of the main clause (often referred to as an "early" vs. "late closure" ambiguity). Subcategorization…

Two experiments examined the role of presupposed (or old) and focal (or new) information in integrating sentences, by measuring comprehension time for various combinations of presupposed and focal information. (Author/AM)

Three experiments examined preschoolers' and adults' understanding of distinctive semantic functions of adjectives and count nouns. Found that 4-year olds and adults, but not 3-year olds, who heard the adjective version (e.g., "a blue bird") were more likely than those who heard the count noun version ("a bluebird") to choose…

Three experiments tested 3-year-olds' subordinate classification. The first experiment found that novel noun presentation hindered classification. The second and third experiments found that provision of information for the purpose of distinguishing relevant subclasses, and introduction of novel nouns in conjunction with familiar basic level…

This study analyzed data from a diary study of a child's lexical development. Correct forms and errors in the use of the plural morpheme were recorded from 18 to 30 months. Morphology was acquired before syntax, and there was evidence for a syntactic definition of noun by the age of 20 months. (BC)

Addressed whether hierarchical relations and word order can be separated in sentence production. Assessed in two experiments whether subject-verb agreement errors require linear proximity of a so-called "local" noun to the verb. Found evidence for a stage in language production in which a syntactic structure is built prior to stage in which words…

Dissociations in the recognition of specific classes of words have been documented in brain-injured populations. These include deficits in the recognition and production of morphologically complex words as well as impairments specific to particular syntactic classes such as verbs. However, functional imaging evidence for distinctions among the…

We assessed the effect of additional tasks on language perception in second-language and native speakers. The N400 component of the event-related potential was recorded to spoken nouns that had to be judged for synonymity with a preceding word, while additional choice responses were required to visual stimuli. In both participant groups N400 was…
