Drawing on the adaptive control hypothesis, we examined whether older adults' bilingual interactional contexts of conversational exchanges would predict important indices of executive functions (EF). We assessed participants' engagement in each bilingual interactional context - single-language, dual-language, and dense code-switching - and their performance on a series of nonverbal EF measures. Sixty-nine healthy older adults (M-age = 70.39 years; ages 60-93) were recruited from local community centers. We found that the dense code-switching context was associated with enhanced overall EF, but not individual facets of EF (inhibitory control, shifting, and updating). These findings held true when we controlled for a …

Bilinguals engage in qualitatively different code-switching patterns (alternation, insertion, and congruent lexicalization) to different degrees, according to their engagement in different types of interactional contexts (single-language context, dual-language context, and dense code-switching context). Drawing on the adaptive control hypothesis, we examined whether bilinguals’ code-switching patterns would differentially shape multiple aspects of cognitive control (interference control, salient cue detection, and opportunistic planning). We found that a dense code-switching context, which predominantly involves insertion and congruent lexicalization, was positively associated with verbal opportunistic planning but negatively associated with interference control and salient cue detection. In contrast, a dual-language context, which predominantly involves …
Mitigation Of A Prospective Association Between Early Language Delay At Toddlerhood And Adhd Among Bilingual Preschoolers: Evidence From The Gusto Cohort, Shaun K. Y. Goh, Hwajin Yang, Stella Tsotsi, Anqi Qiu, Yap-Seng Chong, Kok Hian Tan, Lynette Shek, Birit F. P. Broekman, Anne Rifkin-Graboi

There is accumulating evidence of a prospective relation between early language problems and ADHD, a disorder associated with deficits in executive functioning. However, little is known regarding this link among bilingual children. Here, we investigate whether (i) the prediction from language to ADHD may be lower among bilinguals, and (ii) explore if this moderation can be explained by differential executive functioning ability. Utilising a prospective sample of 408 South-East Asian toddlers, bilingual exposure as a moderator of the link between language delay at 24 months to ADHD intermediate diagnosis at 54 months was first examined with an interaction model. Next, …
The Effects Of Script Variation, Literacy Skills, And Immersion Experience On Executive Attention: A Comparison Of Matched Monoscriptal And Biscriptal Bilinguals, Sujin Yang, Hwajin Yang, Andree Hartanto
The Effects Of Script Variation, Literacy Skills, And Immersion Experience On Executive Attention: A Comparison Of Matched Monoscriptal And Biscriptal Bilinguals, Sujin Yang, Hwajin Yang, Andree Hartanto
Research Collection School of Social Sciences
To examine script effects, monoscriptal Spanish-English (SE) bilinguals, who use two similar Roman alphabetic systems, were compared to biscriptal Chinese-English (CE) bilinguals, who use logographs and Roman alphabets. On the Attention Network Test, script effects were most evident in global processing efficiency (i.e., inverse efficiency and reaction time) and in the local network of executive control in favor of biscriptal CE bilinguals over matched monoscriptal SE counterparts. Literacy effects were found on the executive control network among Chinese-English bilinguals of high L1-literacy skills over their script- and immersion-matched counterparts, who varied only in low L1 literacy. In a similar vein, …
Bilingualism Confers Advantages In Task Switching: Evidence From The Dimensional Change Card Sort Task, Hwajin Yang, Andree Hartanto, Sujin Yang
Bilingualism Confers Advantages In Task Switching: Evidence From The Dimensional Change Card Sort Task, Hwajin Yang, Andree Hartanto, Sujin Yang
Research Collection School of Social Sciences
We examined the influence of bilingualism on task switching by inspecting various markers for task-switching costs. English monolinguals and Korean–English bilinguals completed a modified Dimensional Change Card Sort task based on a nonverbal task-switching paradigm. We found advantages for Korean–English bilinguals in terms of smaller single-task (pure-block) switch costs and greater reactivation benefits than those of English monolinguals. However, bilingual advantages in mixing costs were relatively weak, and the two groups did not differ on local switch costs. Notably, when we approximated the cue-based priming effect in single-task (pure) blocks, we found no evidence that the locus of bilingual advantages …
The Role Of Bilingual Interactional Contexts In Predicting Interindividual Variability In Executive Functions: A Latent Variable Analysis, Andree Hartanto
The Role Of Bilingual Interactional Contexts In Predicting Interindividual Variability In Executive Functions: A Latent Variable Analysis, Andree Hartanto
Dissertations and Theses Collection (Open Access)
Despite a huge number of studies examining bilingual advantages in executive functions (EFs), the research findings with regards to the relations between bilingualism and EFs are mostly inconsistent and mixed. In order to shed light on these inconsistent findings, the current research aimed to tackle on both conceptual and methodological limitations that are prevalent in previous studies, namely: (a) failure to consider bilingual experiences in assessing bilingual advantages, and (b) task impurity due to substantial influence of non-EFs processes on EFs task performance. Based on Adaptive Control Hypothesis and Control Process Model of Code-switching, a theory-driven multisession study coupled with …
Bilingualism Positively Predicts Mathematical Competence: Evidence From Two Large-Scale Studies, Andree Hartanto, Hwajin Yang, Sujin Yang
Bilingualism Positively Predicts Mathematical Competence: Evidence From Two Large-Scale Studies, Andree Hartanto, Hwajin Yang, Sujin Yang
Research Collection School of Social Sciences
Although little is known about the link between bilingualism and mathematical achievement in children, the established link between executive functions (EFs) and mathematical achievement suggests that bilingualism—which has been shown to affect EFs—may positively predict math skills. Drawing on two large-scale datasets collected in the US—the Multi-State Study of Pre-Kindergarten and the State-Wide Early Education Programs (Study 1) and the Early Childhood Longitudinal Study (Study 2)—we examined the relation between bilingualism and mathematical achievement among preschoolers, kindergarteners, and first-grade students (ages 4–7), while controlling for key covariates of (a) demographic variables, such as age, gender, race/ethnicity, and socioeconomic status; and …
Are All Interferences Bad? Bilingual Advantages In Working Memory Are Modulated By Varying Demands For Controlled Processing, Hwajin Yang, Sujin Yang
Are All Interferences Bad? Bilingual Advantages In Working Memory Are Modulated By Varying Demands For Controlled Processing, Hwajin Yang, Sujin Yang
Research Collection School of Social Sciences
We investigated bilingual advantages in general control abilities using three complex-span tasks of working memory (WM). An operation-span task served as a baseline measure of WM capacity. Additionally, two modified versions of the Stroop-span task were designed to place varying attentional-control demands during memoranda encoding by asking participants either to read the to-be-remembered item aloud (lower cognitive control; i.e., Stroop-span task) or to name the font color of the to-be-remembered item while still encoding the word for later recall (greater cognitive control; i.e., attention-impeded Stroop-span task). Twenty-six Korean-English bilinguals and 25 English-native monolinguals were tested. We found that bilinguals outperformed …
Conceptual Representation Changes In Indonesian-English Bilinguals, Andree Hartanto, Lidia Suarez
Conceptual Representation Changes In Indonesian-English Bilinguals, Andree Hartanto, Lidia Suarez
Research Collection School of Social Sciences
This study investigated conceptual representations changes in bilinguals. Participants were Indonesian-English bilinguals (dominant in Indonesian, with different levels of English proficiency) and a control group composed of English-dominant bilinguals. All completed a gender decision task, in which participants decided whether English words referred to a male or female person or animal. In order to explore conceptual representations, we divided the words into gender-specific and gender-ambiguous words. Gender-specific words were words in which conceptual representations contained gender as a defining feature, in both English and Indonesian (e.g., uncle). In contrast, gender-ambiguous words were words in which gender was a defining feature …
Disparate Bilingual Experiences Modulate Task-Switching Advantages: A Diffusion-Model Analysis Of The Effects Of Interactional Context On Switch Costs, Andree Hartanto, Hwajin Yang
Disparate Bilingual Experiences Modulate Task-Switching Advantages: A Diffusion-Model Analysis Of The Effects Of Interactional Context On Switch Costs, Andree Hartanto, Hwajin Yang
Research Collection School of Social Sciences
Drawing on the adaptive control hypothesis (Green & Abutalebi, 2013), we investigated whether bilinguals' disparate interactional contexts modulate task-switching performance. Seventy-five bilinguals within the single-language context (SLC) and 58 bilinguals within the dual-language context (DLC) were compared in a typical task-switching paradigm. Given that DLC bilinguals switch between languages within the same context, while SLC bilinguals speak only one language in one environment and therefore rarely switch languages, we hypothesized that the two groups' stark difference in their interactional contexts of conversational exchanges would lead to differences in switch costs. As predicted, DLC bilinguals showed smaller switch costs than SLC …
The Importance Of Bilingual Experience In Assessing Bilingual Advantages In Executive Functions, Hwajin Yang, Andree Hartanto, Sujin Yang
The Importance Of Bilingual Experience In Assessing Bilingual Advantages In Executive Functions, Hwajin Yang, Andree Hartanto, Sujin Yang
Research Collection School of Social Sciences
Paap, Johnson, and Sawi (2015) contend that bilingual advantages in executive functions (EF) do not exist, and that there is no compelling evidence that a certain bilingual experience hones a specific component of EF (p. 272). We believe that this conclusion is premature, because Paap et al.'s approach was not sufficiently refined to effectively capture the real-world complexity of bilingualism. In this commentary, we draw on the adaptive control hypothesis (Green & Abutalebi, 2013) and argue that studies of bilingualism should consider specific bilingual experiences that potentially moderate bilingual advantages through substantial demand for language control (for similar commentaries, see …
Does Bilingual Fluency Moderate The Disruption Effect Of Cultural Cues On Second-Language Processing?, Sujin Yang, Hwajin Yang
Does Bilingual Fluency Moderate The Disruption Effect Of Cultural Cues On Second-Language Processing?, Sujin Yang, Hwajin Yang
Research Collection School of Social Sciences
Zhang et al. (1) argue that cultural priming disrupts bilinguals’ second-language (L2) processing because of interference from first-language (L1) structures that are activated by heritage-culture images. Although these findings are compelling, we have some concerns about the study. First, Zhang et al. (1) measured English fluency by words spoken per minute after extraneous words (e.g., repetitions and self-corrections) were pruned. Despite the assumed effectiveness of this technique, speech-rate analysis that focuses solely on temporal qualities cannot adequately capture the multifaceted nature of fluency (2), which entails not only speed fluency (i.e., speech rate) but also breakdown fluency (e.g., mean length …
