Abstract 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 alternation, was not associated with interference control or salient cue detection, but with significantly reduced response times for opportunistic planning. Our findings partially corroborate the theoretical predictions of the adaptive control hypothesis. Altogether, our study illustrates the importance of bilinguals’ disparate code-switching practices in shaping cognitive control outcomes.

The adaptive control hypothesis developed by Green and Abutalebi is the most influential theory of bilingual language control. The focus of this article is on the predictions that other researchers have derived based on the three different modes of interactional context described by the hypothesis. Foremost, that dual-language contexts should enhance domain-general executive functions more than single-language contexts. Several recent and ambitious behavioral tests of these predictions are reviewed. Although there was some evidence that dual-language contexts are associated with smaller switch costs, the evidence is inconsistent and there were no similar advantages for inhibitory control. The hypothesis also predicts neuroanatomical adaptations to the three types of interactional context. A careful evaluation of the relevant fMRI and ERP studies that take into account whether behavioral differences align with neuroscience differences and resolves valence ambiguities led to the conclusion that the neuroscience evidence for the hypothesis is, at best, inconsistent. The study also includes new analyses of two large-sample studies that enable the identification of relatively pure cases of single-language bilinguals, dual-language bilinguals, and dense-code switchers. Across nine different measures of executive functioning, the predicted advantage of the dual-language context never materialized. The hypotheses derived from the adaptive control hypothesis do not accurately predict behavioral performance on tests of executive functioning and do not advance our understanding as to what dimensions of bilingualism may lead to enhancements in specific components of executive functioning.

The relationship between bilingualism and cognitive control has been controversial. We believe that the discrepant findings are likely driven by the complexities of the bilingual experience, which is consistent with the Adaptive Control Hypothesis. The current study investigates whether the natural language immersion experience and the classroom intensive language training experience have differential impacts on cognitive control. Among unbalanced Chinese-English bilingual students, a natural L2 (second language) immersion group, an L2 public speaking training group, and a control bilingual group without immersion or training experience were compared on their cognitive control abilities, with the participants’ demographic factors strictly controlled. The results showed that the L2 immersion group and the L2 speaking group had faster speed than the control group in the Flanker task, whereas the L2 immersion group had fewer errors than the other two groups in the Wisconsin Card Sorting Test (WCST). These results generally provide evidence in favor of the Adaptive Control Hypothesis, specifying that natural L2 immersion and L2 public speaking training experiences are distinctively related to cognitive control. The current study is the first of its kind to link specific bilingual experiences (natural L2 immersion vs. intensive L2 public speaking) with different components of cognitive control.

AbstractThe current study explored bilingual parent and child code-switching patterns over time. Concurrent and predictive models of code-switching behaviour on executive function outcomes were also examined in a sample of 29 French–English bilinguals at 36 (Wave 1) and 61 (Wave 2) months of age. We investigated whether code-switching typology in a single-language context predicted executive function performance at each wave independently, and whether growth in code-switching frequency across waves predicted executive function performance at Wave 2. At both waves, parents and children participated in two free play sessions (in English and French), followed by a battery of executive function tasks administered in the dominant language. Results indicate more frequent code-switching from the non-dominant to the dominant language in children, and that children code-switch to fill lexical gaps. Results also suggest that less frequent code-switching in a single-language context is associated with better inhibitory control skills during the preschool period.

Aims and objectives/purpose/research questions: The aim of this study is to investigate the sociolinguistic functions of code-switching and its relation to the meaning-making process by using the animated series Kim Possible as a case study. Design/methodology/approach: This study employs Muysken’s taxonomy to draw on code-switching patterns in lexico-grammar in relation to human behavior. The study also uses the functional approaches of Muysken and Appel and Gumperz as binary investigatory frameworks to locate interlingual and intralingual code-switching particularities and to elaborate on code-switching functions. Data and analysis: The analysis encompasses 48 episodes. Firstly, we extracted and transcribed code-switching occurrences in light of Muysken’s typology episode-by-episode and categorized them according to their code-switching type (interlingual or intralingual). Secondly, we quantified the occurrences according to their syntactic form to make more systematic claims about code-switching patterns. Next, we triangulated the patterns by examining the context of utterances and extralinguistic factors in the original series vis-à-vis the dubbed version to draw upon information beyond the structure or grammar. Findings/conclusions: The Arabic dubbed version was able to communicate the characters’ cosmopolitan diversity, which correlates with the series’ sense of linguistic modernity and humor. At the same time, the Arabic version was able to portray the extralinguistic reality of Lebanon and its multi-linguistic tapestry. Originality: This research is original because it focuses on Lebanese-Arabic, a dialect seldom discussed in the context of translation. The research also examines language variations in the context of dubbed discourse, where code-switching is integrally pertinent to visual-signs and the cultural background of characters. Significance/implications: The study recognizes the intricacy of code-switching as a reflective phenomenon of social reality and power dynamics; therefore, it contributes in the fields of translation and sociolinguistics.

Aims and objectives/purpose/research questions: This study aims to improve our understanding of common switching patterns by examining determiner–noun–adjective complexes in code-switching (CS) in three language pairs (Welsh–English, Spanish–English and Papiamento–Dutch). The languages differ in gender and noun–adjective word order in the noun phrase (NP): (a) Spanish, Welsh, and Dutch have gender; English and Papiamento do not; (b) Spanish, Welsh, and Papiamento prefer post-nominal adjectives; Dutch and English, prenominal ones. We test predictions on determiner language and adjective order derived from generativist accounts and the Matrix Language Frame (MLF) approach. Design/methodology/approach: We draw on three publicly available spoken corpora. For the purposes of these analyses, we re-coded all three datasets identically. From the three re-coded corpora we extracted all monolingual and mixed simplex NPs (DetN) and complex NPs with determiners (determiner–adjective–noun (DetAN/NA)). We then examined the surrounding clause for each to determine the matrix language based on the finite verb. Data and analysis: We analysed the data using a linear regression model in R statistical software to examine the distribution of languages across word class and word order in the corpora. Findings/conclusions: Overall, the generativist predictions are borne out regarding adjective positions but not determiners and the MLF accounts for more of the data. We explore extra-linguistic explanations for the patterns observed. Originality: The current study has provided new empirical data on nominal CS from language pairs not previously considered. Significance/implications: This study has revealed robust patterns across three corpora and taken a step towards disentangling two theoretical accounts. Overall, the findings highlight the importance of comparing multiple language pairs using similar coding.

The human brain has the impressive capacity to adapt how it processes information to high-level goals. While it is known that these cognitive control skills are malleable and can be improved through training, the underlying plasticity mechanisms are not well understood. Here, we develop and evaluate a model of how people learn when to exert cognitive control, which controlled process to use, and how much effort to exert. We derive this model from a general theory according to which the function of cognitive control is to select and configure neural pathways so as to make optimal use of finite time and limited computational resources. The central idea of our Learned Value of Control model is that people use reinforcement learning to predict the value of candidate control signals of different types and intensities based on stimulus features. This model correctly predicts the learning and transfer effects underlying the adaptive control-demanding behavior observed in an experiment on visual attention and four experiments on interference control in Stroop and Flanker paradigms. Moreover, our model explained these findings significantly better than an associative learning model and a Win-Stay Lose-Shift model. Our findings elucidate how learning and experience might shape people’s ability and propensity to adaptively control their minds and behavior. We conclude by predicting under which circumstances these learning mechanisms might lead to self-control failure.

IntroductionAffective disturbances and difficulty in affect regulation are core features of major depressive disorder (MDD) as well as borderline personality disorder (BPD). Whereas depressed individuals are characterised by affective inertia, individuals with BPD are characterised by affective instability. Both groups have been found to use more maladaptive affect regulation strategies than healthy controls. Surprisingly, however, there have been hardly any studies directly comparing these two disorders to disentangle shared and disorder-specific deficits in affective dynamics and affect regulation.Furthermore, theoretical models link deficits in affect regulation to deficits in cognitive control functions. Given that individuals with MDD or BPD are both characterised by impairments in cognitive control, the present study will further examine the link between individual differences in cognitive control and disturbances in affect dynamics and regulation in the daily life of individuals with MDD or BPD.Methods and analysesWe will use a smartphone application to assess negative and positive affect as well as affect regulation strategies at eight times a day for 7 days. We will further employ four computerised tasks to assess two cognitive control functions, namely interference control and discarding irrelevant information from working memory. Our hypotheses will be tested using a multimethod approach. Power analyses determined a sample size of 159 (53 MDD, 53 BPD, 53 controls) to detect medium effect sizes.Ethics and disseminationEthics approval has been obtained from the Freie Universität Berlin. Data collection started in January 2017 and will last until the end of 2018. Results will be disseminated to relevant psychotherapeutic and patient communities in peer-reviewed journals, and at scientific conferences.

Differential evolution (DE) algorithm has been applied as a powerful tool to find optimum switching angles for selective harmonic elimination pulse width modulation (SHEPWM) inverters. However, the DE’s performace is very dependent on its control parameters. Conventional DE generally uses either trial and error mechanism or tuning technique to determine appropriate values of the control paramaters. The disadvantage of this process is that it is very time comsuming. In this paper, an adaptive control parameter is proposed in order to speed up the DE algorithm in optimizing SHEPWM switching angles precisely. The proposed adaptive control parameter is proven to enhance the convergence process of the DE algorithm without requiring initial guesses. The results for both negative and positive modulation index (<em>M</em>) also indicate that the proposed adaptive DE is superior to the conventional DE in generating SHEPWM switching patterns
