Abstract [en]

The purpose of the present study was to compare between bilingual and monolingual university students to examine if there was any difference regarding two aspects of cognitive flexibility: the switch cost and perseverative errors. It was hypothesized that bilinguals should have significantly reduced switch cost and perseverative errors than monolinguals. These aspects were tested by conducting two experiments involving task switch processing: the Alternating Runs Task Switch Paradigm and Wisconsin Card Sorting Task. The convenient sample consisted of 64 bilingual and monolingual university students. The test results were analyzed through multiple independent T-tests. The results showed non-significant differences in the switch cost and perseverative errors between bilingual and monolingual university students. These results were discussed with previous research in mind and confirmed the inconsistency within the literature regarding cognitive differences between bilingual and monolingual young adults.

Abstract [sv]

Syftet med studien var att jämföra tvåspråkiga och enspråkiga universitetsstudenter för att undersöka i fall de skiljer sig i två aspekter av kognitiv flexibilitet: switch kostnad och fasthållande fel. De två aspekterna testades genom två experiment som innehåller skiften mellan olika uppgifter: Alternating runs task switch paradigm och Wisconsin card sorting task. Bekvämlighetsurvalet bestod av 64 tvåspråkiga och enspråkiga universitetsstudenter. Resultaten analyserades genom flera oberoende T-test. Resultaten visade en icke-signifikant skillnad i switch cost och perseverative errors mellan tvåspråkiga och enspråkiga universitetsstudenter. Dessa resultat diskuterades i enlighet med tidigare forskning och bekräftar forskningens inkonsistens rörande kognitiva skillnader mellan tvåspråkiga och enspråkiga unga vuxna.
