Toddlerhood is marked by advances in several lexico-semantic skills, including improvements in the size and structure of the lexicon and increased efficiency in lexical processing. This project seeks to delineate how early changes in vocabulary size and vocabulary structure support lexical processing (Experiment 1), and how these three skills…

In this plenary paper, we present a review of language research in children with cochlear implants along with an outline of a 5-year project designed to examine the lexical access for production and recognition. The project will use auditory priming, picture naming with auditory or visual interfering stimuli (Picture-Word Interference and…

The present study examined language production skills in Parkinson's disease (PD) patients. A unique cued sentence generation task was created in order to reduce demands on memory and attention. Differences in sentence production abilities according to disease severity and cognitive impairments were assessed. Language samples were obtained from 20…

In this paper we present an unsupervised neural network model of bilingual lexical development and interaction. We focus on how the representational structures of the bilingual lexicons can emerge, develop, and interact with each other as a function of the learning history. The results show that: (1) distinct representations for the two lexicons…

Previous studies on second language (L2) acquisition of English dative alternation by Korean speakers (Oh and Zubizarreta, 2003, 2006a, 2006b) have shown that the acquisition of English benefactive double object (DO) (e.g. "John baked Mary a cake") lags behind that of its counterpart goal double object (e.g. "John sent Mary the letter"). This…

Two experiments examined the time course of lexical information availability in 20 adults, 20 children (8;0-10;0) with typical language development, and in 20 children (8;0-10;0) with specific language impairment. A cross-modal picture-word interference paradigm was used in which participants named the pictures as quickly as possible while…

Bilinguals are better able to perceive speech-in-noise in their native compared to their non-native language. This benefit is thought to be due to greater use of higher-level, linguistic context in the native language. Previous studies showing this have used sentences and do not allow us to determine which level of language contributes to this…

This article studies the acquisition of copulas by a Spanish-English bilingual between the ages of 1;6 and 3;0, examines the possibility of interlanguage influence, and considers the distributional frequencies of copular constructions in the speech of the child and in the language input from adults. The study is of interest because the bilingual…

We investigate how L1 phonology and semantics affect processing of interlingual homographs by manipulating language context before, and auditory input during, a visual experiment in the L2. Three experiments contained German-English homograph primes ("gift" = German "poison") in English sentences and was performed by German (L1) learners of…

How does the development and consolidation of perceptual, attentional, and higher cognitive abilities interact with language acquisition and processing? We explored children's (ages 5-17) and adults' (ages 18-51) comprehension of morphosyntactically varied sentences under several competing speech conditions that varied in the degree of attentional…

Studied bilingual children and children learning a second language using a picture-word interference task. The printed distractors interfered with naming both on trials where the distractor and naming language were the same and on trials where they were different. These and other results question whether an "input switch" operates for bilingual…

We assessed the impact of visual similarity on written word identification by having participants learn new words (e.g. BANARA) that were neighbours of familiar words that previously had no neighbours (e.g. BANANA). Repeated exposure to these new words made it more difficult to semantically categorize the familiar words. There was some evidence of…

The Stroop paradigm was used to examine the role of phonological activation in semantic access and its development in reading Chinese characters. Subjects (age 7-23 years) of different reading ability were asked to name the display color of Chinese characters. The characters were displayed in four different colors: red, yellow, blue and green.…

Preliminary results from a longitudinal study of English-speaking children and adults learning Dutch in natural situations suggest that 12- to 15-year-olds learned faster than either older or younger subjects during their first 6 months in Holland. All age differences had disappeared in a group of advanced subjects (English-speakers who had been…

It is a matter of debate whether the two differentiated grammatical systems in a bilingual child develop autonomously, or whether there is interdependence and in what areas (Genesee, 2001; Meisel, 2001). Extensive research is being carried out in the emergence of the two grammars, but not much attention has been given to the development of…
