English-speakers' learning of a French vowel contrast (/ə/–/ø/) was examined under six different stimulus conditions in which contrastive and noncontrastive stimulus dimensions were varied orthogonally to each other. The distribution of contrastive cues was varied across training conditions to create single prototype, variable far (from the category boundary), and variable close (to the boundary) conditions, each in a single talker or a multiple talker version. The control condition involved identification of gender appropriate grammatical elements. Pre- and posttraining measures of vowel perception and production were obtained from each participant. When assessing pre- to posttraining changes in the slope of the identification functions, statistically significant training effects were observed in the multiple voice far and multiple voice close conditions.

Attention-deficit/hyperactivity disorder (ADHD) is frequently associated with learning disabilities. The present study examined the written composition of children with ADHD, which depends to a large degree on continuous self-regulation and attentional control skills for organizing information and maintaining the level of effort. Fifty children with ADHD and 50 normally developing children, matched on age and IQ, were assessed using a composition writing task. The results contribute to prior research findings by showing that the children with ADHD performed significantly worse than the comparison groups on the majority of the planning, translation, and revision process measures usually employed to assess the quality of written compositions. Deficiencies in executive functioning or poor linguistic and metalinguistic competence could account for the results found. More research is needed to clarify the underlying causes of the written composition performance profile of children with ADHD.

Often, the classification of words does not go beyond “difficult” (i.e., infrequent, late-learned, nonimageable, etc.) or “easy” (i.e., frequent, early-learned, imageable, etc.) words. In the present study, we used a latent cluster analysis to divide 703 Dutch words with scores for eight word properties into seven clusters of words. Each cluster represents a group of words that share a particular configuration of word properties. This model was empirically validated with three data sets from Grades 2 to 4 children who made either a lexical decision task or a use decision task with a selection of the words. Significant differences were found between the clusters of words within the three data sets. Implications for further study and for practice are discussed.

This paper investigates how learners interpret definite plural noun phrases (e.g., the tigers) and bare (article-less) plural noun phrases (e.g., tigers) in their second language. Whereas Spanish allows definite plurals to have both generic and specific readings, English requires definite plurals to have specific, nongeneric readings. Generic readings in English are expressed with bare plurals, which are ungrammatical in Spanish in preverbal subject position. Two studies were conducted in order to investigate the role of first language transfer in this domain in both English → Spanish and Spanish → English directions. Study 1 used a meaning-focused task to probe learners’ interpretation of definite plural nour phrases, whereas Study 2 used a form-focused task to examine learners’ judgments of the acceptability of definite and bare plurals in generic versus specific contexts. First language transfer was attested in both directions, at lower proficiency levels, whereas more targetlike performance was attested at higher proficiency levels. Furthermore, learners were found to be more successful in learning about the (un)grammaticality of bare plurals in the target language than in assigning the target interpretation to definite versus bare plurals. This finding is shown to be consistent with other studies’ findings of plural noun phrase interpretation in monolingual and bilingual children.

In two eye-tracking experiments we examined whether wider discourse information helps the recognition of reduced pronunciations (e.g., “puter”) more than the recognition of canonical pronunciations of spoken words (e.g., “computer”). Dutch participants listened to sentences from a casual speech corpus containing canonical and reduced target words. Target word recognition was assessed by measuring eye fixation proportions to four printed words on a visual display: the target, a “reduced form” competitor, a “canonical form” competitor, and an unrelated distractor. Target sentences were presented in isolation or with a wider discourse context. Experiment 1 revealed that target recognition was facilitated by wider discourse information. It is important that the recognition of reduced forms improved significantly when preceded by strongly rather than by weakly supportive discourse contexts. This was not the case for canonical forms: listeners’ target word recognition was not dependent on the degree of supportive context. Experiment 2 showed that the differential context effects in Experiment 1 were not due to an additional amount of speaker information. Thus, these data suggest that in natural settings a strongly supportive discourse context is more important for the recognition of reduced forms than the recognition of canonical forms.

We assessed the language, cognitive, and socioemotional abilities of 27 internationally adopted children from China, adopted by French-speaking parents, 12 of whom had been assessed previously by Gauthier and Genesee. The children were on average 7 years, 10 months old and were matched to nonadopted monolingual French-speaking children on age, gender, and socioeconomic status. Although there were no significant differences between the groups with respect to socioemotional and cognitive development, the adoptees scored significantly lower than the controls on measures of receptive grammar, expressive vocabulary, word definitions, and sentence recall, findings that were similar to those reported by Gauthier and Genesee. Analyses of correlations between the adopted children's language test results and their age at adoption, length of exposure to the adoption language, health, and other developmental problems revealed relatively few significant associations. In contrast, analyses of the relationship between their language test scores and their performance on the recalling sentences subtest suggest a link between performance on these two tests. We speculate on the role that performance on sentence recall might play in mediating differences in language outcomes between the two groups of children.

The goals of the current study were (a) to assess differences in child and adult pausing and (b) to determine whether characteristics of child and adult pausing can be explained by the same language variables. Spontaneous speech samples were obtained from 10 5-year-olds and their accompanying parent using a storytelling/retelling task. Analyses of pause frequency, duration, variation in durations, and pause location indicated that pause time decreased with retelling, but not with age group except when child and adult pausing was considered in its speech and language context. The results suggest that differences in child and adult pausing reflect differences in child and adult language, not in the cognitive resources allocated to language production.

The close relationship between children's vocabulary size and their later academic success has led researchers to explore how vocabulary development might be promoted during the early school years. We describe a study that explored the effectiveness of naturalistic classroom storytelling as an instrument for teaching new vocabulary to 6- to 9-year-old children. We examined whether learning was facilitated by encountering new words in single versus multiple story contexts, or by the provision of age-appropriate definitions of words as they were encountered. Results showed that encountering words in stories on three occasions led to significant gains in word knowledge in children of all ages and abilities, and that learning was further enhanced across the board when teachers elaborated on the new words’ meanings by providing dictionary definitions. Our findings clarify how classroom storytelling activities can be a highly effective means of promoting vocabulary development.

This study examines the roles of proficiency and working memory (WM) capacity in second-/foreign-language (L2) learners’ processing of agreement morphology. It investigates the processing of grammatical and ungrammatical short- and long-distance number agreement dependencies by native English speakers at two proficiencies in French, and the relationship between their proficiency and WM capacity in French and their sensitivity to agreement violations. Native English speakers at mid- and high proficiencies in French and native French speakers completed an acceptability judgment task, a self-paced reading task, and a WM task in French, and the English speakers also completed a WM task in English. The results showed that whereas all participants performed at ceiling on the acceptability judgment tasks, only the high-level L2 learners and native speakers showed some sensitivity to number agreement violations. For L2 learners, this sensitivity did not vary as a function of the length of the agreement dependency. The results also indicated that L2 learners tended to be more sensitive to agreement violations as their WM memory capacity in French increased. The implications of these results for theories of L2 morphological processing are discussed.
