Previous research has studied the relationship between bilingualism and cognitive abilities. In some of those studies results have shown that bilinguals perform better than monolinguals in visual Simon tasks (i.e. they are less distracted by the incongruent stimuli). The aim of the current study is to see if a similar effect can be found in Simon tasks using the tactile and auditory sensory modalities. In this study bilingual participants (36 university students) with different proficiency in their second language performed a Simon task employing two intensities of vibration and two different sounds as the relevant stimuli. The results indicated no negative correlation between either bilingual proficiency and Simon effect or daily use of the second language and Simon effect when controlling for working memory. Without controlling for working memory a negative correlation for the tactile condition and a positive correlation for the auditory condition between Simon effect and daily use of the second language was found. It’s concluded that the statistical power of this study suffers from a lack of participants and that if the test was reproduced with more participants with a greater spread in their language abilities a stronger effect might be seen. Also concluded is that more cross-modal studies need to be performed before conclusions about general cognitive effects of bilingualism can be drawn. / Tidigare forskning har studerat sambandet mellan tvåspråkighet och kognitiva förmågor. Vissa av dessa studiers resultat har visat att tvåspråkiga individer presterar bättre än enspråkiga i visuella Simon-uppgifter (dvs. de blir mindre distraherade av inkongruenta stimuli). Syftet med den aktuella studien är att se om man kan hitta en liknande effekt i Simon-uppgifter inom de taktila och auditiva sensoriska modaliteterna. I denna studie fick tvåspråkiga deltagare (36 universitetsstudenter) med olika kunskaper i sitt andraspråk utföra en Simon-uppgift där två intensiteter av vibrationer och två olika ljud används som relevanta stimuli. När resultaten var kontrollerade för arbetsminne så visades ingen negativ korrelation mellan varken tvåspråkig förmåga och Simon effekt eller daglig användning av det andra språket och Simon effekt. Utan att kontrollera för arbetsminne så fanns det en negativ korrelation för den taktila betingelsen och en positiv korrelation för den auditiva betingelsen mellan daglig användning av andra språk och Simon effekt. Slutsatsen dras att den statistiska kraften i denna studie lider av brist på deltagare och att om testet reproduceras med fler deltagare, med en större spridning i språkförmåga, så skulle en starkare effekt kunna ses. Det konkluderas även att fler tvärmodala studier behöver utföras innan slutsatser om generella kognitiva effekter av tvåspråkighet kan dras.

The purpose of the present study was to examine, based on audio samples in both languages, the accuracy of diagnosis of the presence or absence of stuttering in a bilingual Spanish English (SE) child who may or may not stutter by bilingual SE speech- language pathologists (SLPs) living in Texas (n=14). This study also aimed to determine what speech characteristics (if any) influenced SLPs’ judgment of whether or not a bilingual SE child was a stutterer, as well as to explore whether personal characteristics of the bilingual SLPs who completed the ratings (i.e., years experience, confidence in diagnosing an SE child with stuttering, educational history on the topics of stuttering and/or bilingualism) uniquely impacted the accuracy of their diagnosis. Information gained from this study suggests that the atypically frequent (in comparison to monolingual children) word and phrases repetitions produced by bilingual SE children who do not stutter may put this population at risk for misdiagnosis of stuttering. Results also indicate that the accuracy of identification of a bilingual SE child who does not stutter is not influenced by any of the personal characteristics listed above. Rather, there seems to be an overall lack of knowledge regarding the speech disfluencies that differentiate bilingual SE children who do and do not stutter. Thus, the preliminary data from this investigation warrants a follow-up study of the same nature on a nationwide scale. / text

This research examines the bilingual and biliterate trajectories of graduates of a K-5 dual language immersion program who are now young adults. Their experiences as emergent bilinguals within the setting of their elementary school was foundational for their long-term academic outcomes and their deep metapragmatic awareness of simultaneous linguistic experiences. This study explores where these students are now, what happened since they left this particular dual language program, and how their language practices and ideologies have shifted over time and shaped their current practices and ideologies surrounding language and literacy across time and space. Using qualitative methodology, this study draws on frameworks of New Literacy Studies, communities of practice, language ideologies, capital, and language-as-resource to highlight how bilingualism and biliteracy are complex phenomena, and how the multiple, complex, and competing forces at play ultimately shape language and literacy. This study examines the fluidity of how resources for learning are transformed across multiple landscapes and how important insights arise concerning how retrospective analysis of previous learning environments have shaped students' current lived experiences. Findings illustrate the dynamic nature of bilingualism not through discreet domains of language use in bounded contexts, but fluidly moving across fields in remarkable ways. Additional findings underscore the mobilities of language and literacy and how ideologies are neither static nor fixed, but continuously evolving in fluid and dynamic processes.
