  abstract  = {W{\"a}hrend f{\"u}r den monolingualen Erwerb des T{\"u}rkischen ausreichend Evidenzen vorliegen, dass Kasus innerhalb der ersten drei Lebensjahre erworben wird und Erwerbsprobleme ein sicherer Indikator f{\"u}r SSES sind, ist dies f{\"u}r den bilingualen Erwerb nicht ausreichend gekl{\"a}rt. Die vorliegende Studie untersucht in longitudinalen Daten von ungest{\"o}rten 18 zwei- bis vierj{\"a}hrigen bilingual t{\"u}rkisch-deutsch-sprachigen Kindern die Korrektheitswerte, Entwicklungsmuster und Fehlertypen in einem Elizitierungstest f{\"u}r Akkusativ und Dativ in der Erstsprache T{\"u}rkisch. Auch nach dem vierten Lebensjahr sind die getesteten Bereiche nicht von allen Kindern vollst{\"a}ndig erworben. Der Kasus ist demnach unter bilingualen Erwerbsbedingungen ein vulnerabler Bereich und als alleiniger Marker nicht geeignet, um zwischen gest{\"o}rter und ungest{\"o}rter bilingualer Sprachentwicklung zu unterscheiden. Das h{\"a}ufige Ausweichen auf pronominale Reaktionen und andere W{\"o}rter auf Grund lexikalischer Unsicherheiten, verdeutlicht die Notwendigkeit von erstsprachlichen Kompetenzen bei der Beurteilung der Korrektheit der Reaktionen.},

  abstract  = {Matching participants (as suggested by Hope, 2015) may be one promising option for research on a potential bilingual advantage in executive functions (EF). In this study we first compared performances in three EF-tasks of a naturally heterogeneous sample of monolingual (n = 69, age = 9.0 y) and multilingual children (n = 57, age = 9.3 y). Secondly, we meticulously matched participants pairwise to obtain two highly homogeneous groups to rerun our analysis and investigate a potential bilingual advantage. The initally disadvantaged multilinguals (regarding socioeconomic status and German lexicon size) performed worse in updating and response inhibition, but similarly in interference inhibition. This indicates that superior EF compensate for the detrimental effects of the background variables. After matching children pairwise on age, gender, intelligence, socioeconomic status and German lexicon size, performances became similar except for interference inhibition. Here, an advantage for multilinguals in the form of globally reduced reaction times emerged, indicating a bilingual executive processing advantage.},

  abstract  = {We aimed at unveiling the role of executive functions (EFs) and language-related skills in spelling for mono- versus multilingual primary school children. We focused on EF and language-related skills, in particular lexicon size and phonological awareness (PA), because these factors were found to predict spelling in studies predominantly conducted with monolinguals, and because multilingualism can modulate these factors. There is evidence for (a) a bilingual advantage in EF due to constant high cognitive demands through language control, (b) a smaller mental lexicon in German and (c) possibly better PA. Multilinguals in Germany show on average poorer German language proficiency, what can influence performance on language-based tasks negatively. Thus, we included two spelling tasks to tease apart spelling based on lexical knowledge (i.e., word spelling) from spelling based on non-lexical strategies (i.e., non-word spelling). Our sample consisted of heterogeneous third graders from Germany: 69 monolinguals (age: M = 108 months) and 57 multilinguals (age: M = 111 months). On less language-dependent tasks (e.g., non-word spelling, PA, intelligence, short-term memory (STM) and three EF tasks testing switching, inhibition, and working memory) performance of both groups did not differ significantly. However, multilinguals performed significantly more poorly on tasks measuring German lexicon size and word spelling than monolinguals. Regression analyses revealed that for multilinguals, inhibition was related to spelling, whereas switching was the only EF component to influence word spelling in monolinguals and non-word spelling performance in both groups. By adding lexicon size and other language-related factors to the regression models, the influence of switching was reduced to insignificant effects, but inhibition remained significant for multilinguals. Language-related skills best predicted spelling and both language groups shared those variables: PA for word spelling, and STM for non-word spelling. Additionally, multilinguals' word spelling performance was also predicted by their German lexicon size, and non-word spelling performance by PA. This study offers an in-depth look at spelling acquisition at a certain point of literacy development. Mono- and multilinguals have the predominant factors for spelling in common, but probably due to superior language knowledge, monolinguals were already able to make use of EF during spelling. For multilinguals, German lexicon size was more important for spelling than EF. For multilinguals' spelling these functions might come into play only at a later stage.},

Von der ersten Klasse an zeigt sich eine hohe Korrektheit in der Schreibung und somit eine sprachspezifisch schnelle Entwicklung der alphabetischen Rechtschreibstrategie f{\"u}r finale Konsonantencluster. Der Einfluss morphologischer Verarbeitungsprozesse wurde allerdings erst f{\"u}r die Drittkl{\"a}ssler_innen gefunden.
