Abstract Bilinguals sometimes show crosslinguistic influence from one language to another while speaking (or gesturing). Adult bilinguals have also shown crosslinguistic influence in gestures as well as speech, suggesting an underlying conceptualization that is similar for both languages. The primary purpose of the present study is to test if the same is true of simultaneous French-English bilingual children in speaking and gesturing about motion. If so, they might show different patterns from both French and English monolinguals. Furthermore, we examined whether there were developmental changes between early and middle childhood. French-English bilingual and French and English monolingual children watched two cartoons and described them. In speech, the bilinguals differed from the English monolinguals, using more lexicalizations of the Path of motion in token numbers but not in type. They did not differ from the French monolinguals. In gestures, all children used a majority of Path gestures. There were few age-related changes. We argue that in speech, the bilinguals conceptualize their two languages differently, but show some crosslinguistic influence due to processing. Gestures may not show this same pattern, because they serve to highlight the important parts of the discourse.

Our understanding of the structure and the formation of inorganic minerals in the bivalve shells has been considerably advanced by the use of electron microscope. However, very little is known about the ultrastructure of valves in the larval stage of the oysters. The present study examines the developmental changes which occur between the time of conception to the early stages of Dissoconch in the Crassostrea virginica(Gmelin), focusing on the initial deposition of inorganic crystals by the oysters.The spawning was induced by elevating the temperature of the seawater where the adult oysters were conditioned. The eggs and sperm were collected separately, then immediately mixed for the fertilizations to occur. Fertilized animals were kept in the incubator where various stages of development were stopped and observed. The detailed analysis of the early stages of growth showed that CaCO3 crystals(aragonite), with orthorhombic crystal structure, are deposited as early as gastrula stage(Figuresla-b). The next stage in development, the prodissoconch, revealed that the crystal orientation is in the form of spherulites.

Mean Length Of Utterance

Purpose The purpose of this study is to examine the frequency and type of speech disfluencies (stuttering-like and nonstuttering-like) in bilingual Spanish–English (SE) children who stutter (CWS) to SE children who do not stutter (CWNS) during narrative samples elicited in Spanish and English to provide further diagnostic information for this population and preliminary data toward an expansion of this study. Method Participants included six bilingual SE children (three CWS, three CWNS) ranging in age from 5 years to 7;5 (years;months) and recruited from the surrounding Houston, Texas area. Participants provided a narrative sample in English and Spanish. The frequency of speech disfluencies was tabulated, and mean length of utterance was measured for each sample. Results Results indicate that both talker groups exceed the diagnostic criteria typically used for developmental stuttering. Regardless of the language being spoken, CWS participants had a frequency of stuttering-like speech disfluencies that met or exceeded the diagnostic criteria for developmental stuttering that is based on monolingual English speakers. The CWNS participants varied in meeting the criteria depending on the language being spoken, with one of the three CWNS exceeding the criteria in both languages and one exceeding the criteria for percentage of stuttering-like speech disfluencies in one language. Conclusion Findings from this study contribute to the development of more appropriate diagnostic criteria for bilingual SE-speaking children to aid in the reduction of misdiagnoses of stuttering in this population.
