Während für den monolingualen Erwerb des Türkischen ausreichend Evidenzen vorliegen, dass Kasus innerhalb der ersten drei Lebensjahre erworben wird und Erwerbsprobleme ein sicherer Indikator für SSES sind, ist dies für den bilingualen Erwerb nicht ausreichend geklärt. Die vorliegende Studie untersucht in longitudinalen Daten von ungestörten 18 zwei- bis vierjährigen bilingual türkisch-deutsch-sprachigen Kindern die Korrektheitswerte, Entwicklungsmuster und Fehlertypen in einem Elizitierungstest für Akkusativ und Dativ in der Erstsprache Türkisch. Auch nach dem vierten Lebensjahr sind die getesteten Bereiche nicht von allen Kindern vollständig erworben. Der Kasus ist demnach unter bilingualen Erwerbsbedingungen ein vulnerabler Bereich und als alleiniger Marker nicht geeignet, um zwischen gestörter und ungestörter bilingualer Sprachentwicklung zu unterscheiden. Das häufige Ausweichen auf pronominale Reaktionen und andere Wörter auf Grund lexikalischer Unsicherheiten, verdeutlicht die Notwendigkeit von erstsprachlichen Kompetenzen bei der Beurteilung der Korrektheit der Reaktionen.

Due to their multifunctionality, tablets offer tremendous advantages for research on handwriting dynamics or for interactive use of learning apps in schools. Further, the widespread use of tablet computers has had a great impact on handwriting in the current generation. But, is it advisable to teach how to write and to assess handwriting in pre- and primary schoolchildren on tablets rather than on paper? Since handwriting is not automatized before the age of 10 years, children's handwriting movements require graphomotor and visual feedback as well as permanent control of movement execution during handwriting. Modifications in writing conditions, for instance the smoother writing surface of a tablet, might influence handwriting performance in general and in particular those of non-automatized beginning writers. In order to investigate how handwriting performance is affected by a difference in friction of the writing surface, we recruited three groups with varying levels of handwriting automaticity: 25 preschoolers, 27 second graders, and 25 adults. We administered three tasks measuring graphomotor abilities, visuomotor abilities, and handwriting performance (only second graders and adults). We evaluated two aspects of handwriting performance: the handwriting quality with a visual score and the handwriting dynamics using online handwriting measures [e.g., writing duration, writing velocity, strokes and number of inversions in velocity (NIV)]. In particular, NIVs which describe the number of velocity peaks during handwriting are directly related to the level of handwriting automaticity. In general, we found differences between writing on paper compared to the tablet. These differences were partly task-dependent. The comparison between tablet and paper revealed a faster writing velocity for all groups and all tasks on the tablet which indicates that all participants—even the experienced writers—were influenced by the lower friction of the tablet surface. Our results for the group-comparison show advancing levels in handwriting automaticity from preschoolers to second graders to adults, which confirms that our method depicts handwriting performance in groups with varying degrees of handwriting automaticity. We conclude that the smoother tablet surface requires additional control of handwriting movements and therefore might present an additional challenge for learners of handwriting.

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.
