Entropy is a measure of10/5/2023 Crucially, this study used language entropy as a measure of bilinguals’ language use patterns. To further examine this, the present study relates the social diversity of bilingual language use to performance on a color-shape switching task (CSST) in a group of bilingual university students with diverse linguistic backgrounds. N2 - Introduction: It has been proposed that bilinguals’ language use patterns are differentially associated with executive control. T1 - Language Entropy Relates to Behavioral and Pupil Indices of Executive Control in Young Adult Bilinguals The paper discusses theoretical and practical implications regarding the language entropy measure and the cognitive effects of bilingual experiences more generally, as well as how methodological choices can advance our understanding of these effects.", Importantly, the results also suggest that some of these effects may only be detected by using more sensitive measures, such as pupil dilation. ![]() The paper discusses theoretical and practical implications regarding the language entropy measure and the cognitive effects of bilingual experiences more generally, as well as how methodological choices can advance our understanding of these effects.Ībstract = "Introduction: It has been proposed that bilinguals language use as being associated with executive control, but the direction of the effects may depend on social context (university vs. ![]() No such effects were found for university entropy.ĭiscussion: These results point to the social diversity of bilinguals’ language use as being associated with executive control, but the direction of the effects may depend on social context (university vs. Mixing costs in RTs were reduced for bilinguals with higher diversity of language use in non-university contexts. However, bilinguals with more compartmentalized language use in non-university contexts showed a larger difference in pupil dilation for switch trials in comparison with non-switch trials. ![]() Neither university entropy nor non-university entropy were associated with switching costs as manifested in RTs. Results: Higher university entropy was related to slower global RT. In addition, this study innovatively recorded a potentially more sensitive measure of set shifting abilities, namely, pupil size during task performance. Reaction times (RTs) were measured to calculate global RT and switching and mixing costs on the CSST, representing conflict monitoring, mental set shifting, and goal maintenance, respectively. Methods: Language entropy for university and non-university contexts was calculated from questionnaire data on language use. This continuous measure reflects a spectrum of language use in a variety of social contexts, ranging from compartmentalized use to fully integrated use. ![]() Introduction: It has been proposed that bilinguals’ language use patterns are differentially associated with executive control.
