As studies of bilingual language control (BLC) seek to explore the underpinnings of bilinguals’ abilities to juggle two languages, different types of language switching tasks have been used to uncover switching and mixing effects and thereby reveal what proactive and reactive control mechanisms are involved in language switching. Voluntary language switching tasks, where a bilingual participant can switch freely between their languages while naming, are being utilized more often due to their greater ecological validity compared to cued switching paradigms. Because this type of task had not yet been applied to language switching in bilingual patients, our study sought to explore voluntary switching in bilinguals with aphasia (BWAs) as well as in healthy bilinguals. In Experiment 1, we replicated previously reported results of switch costs and mixing benefits within our own bilingual population of Catalan-Spanish bilinguals. With Experiment 2, we compared both the performances of BWAs as a group and as individuals against control group performance. Results illustrated a complex picture of language control abilities, indicating varying degrees of association and dissociation between factors of BLC. Given the diversity of impairments in BWAs’ language control mechanisms, we highlight the need to examine BLC at the individual level and through the lens of theoretical cognitive control frameworks in order to further parse out how bilinguals regulate their language switching.

Background. Bilingualism results in an added advantage with respect to cognitive control. The interaction between bilingual language control and general purpose cognitive control systems can also be understood by studying executive control among individuals with bilingual aphasia.Objectives. The current study examined the subcomponents of cognitive control in bilingual aphasia. A case study approach was used to investigate whether cognitive control and language control are two separate systems and how factors related to bilingualism interact with control processes.Methods. Four individuals with bilingual aphasia performed a language background questionnaire, picture description task, and two experimental tasks (nonlinguistic negative priming task and linguistic and nonlinguistic versions of flanker task).Results. A descriptive approach was used to analyse the data using reaction time and accuracy measures. The cumulative distribution function plots were used to visualize the variations in performance across conditions. The results highlight the distinction between general purpose cognitive control and bilingual language control mechanisms.Conclusion. All participants showed predominant use of the reactive control mechanism to compensate for the limited resources system. Independent yet interactive systems for bilingual language control and general purpose cognitive control were postulated based on the experimental data derived from individuals with bilingual aphasia.

Abstract There are two primary goals for this study – first, to analyse definiteness and article use in spontaneous writing in Swedish by 15-year-old Finnish immersion students (n = 162) and secondly, to compare their performance with that of non-immersion students at the same age (n = 67). Analyses at the group level show that immersion students usually perform significantly better than the control group, but they also reveal similar problems to what L2-Swedish non-immersion students have demonstrated in previous studies, such as omission of indefinite articles and difficulty in choosing the right definite form of the noun. Still, these inaccuracies occurred less often in the data from the immersion students. The studied constructions also show at the group level an acquisition order similar to that reported in previous studies, explainable by different aspects of complexity and cross-linguistic influence. Analyses on the individual level, however, show different acquisition orders depending on the criteria being used.

AbstractThis study investigated the specific patient factors that predict responsiveness to a cognitive rehabilitation program. The program has previously been demonstrated to be successful at the group level in patients with gliomas, but it is unclear which patient characteristics optimized the effect of the intervention at the individual level. Four categories of possible predictors of improvement were selected for evaluation: sociodemographic and clinical variables, self-reported cognitive symptoms, and objective neuropsychological test performance. Hierarchical logistic regression analyses were conducted, beginning with the most accessible (sociodemographic) variables and ending with the most difficult (baseline neuropsychological) to identify in clinical practice. Nearly 60% of the participants of the intervention were classified as reliably improved. Reliable improvement was predicted by age (p = .003) and education (p = .011). Additional results suggested that younger patients were more likely to benefit specifically from the cognitive rehabilitation program (p = .001), and that higher education was also associated with improvement in the control group (p = .024). The findings are discussed in light of brain reserve theory. A practical implication is that cognitive rehabilitation programs should take the patients’ age into account and, if possible, adapt programs to increase the likelihood of improvement among older participants.

Adults are capable of very fine motor skills whereas newborn babies’ motions are less accurately adjusted to the environment. It has been suggested that babies are sensitive to sensorimotor contingencies so they can acquire their body knowhow by gradually linking each body movement to its perceptual consequences. The research we pursued in the team is part of this theoretical framework. We use behavioural measurements to study how babies refine their body knowhow over time.During my internship, we studied arm differentiation in infants of age 6 months. An artificial contingency was established between the movements of one of the babies’ arms and the appearance of visual and auditory stimuli on both of their arms. My goal was to develop analytical tools to assess if babies detect the contingency (i.e. if they realize that they caused the occurrence of the stimuli). I tried to reproduce the probabilistic methodology developed by J. Watson in his experiments with 4month old babies. I could not obtain reliable results and so pursued my investigations. I adapted Watson’s analytical tools to create a binary indicator measuring the success of babies at the individual level. I showed that babies can differentiate between a situation where without doubt they have no control and a situation where they could be the cause of the stimulus. However, because babies who tried to test the contingency behaved similarly in both the test and the control group I can not ascertain that babies from the contingent group understood that they triggered the contingency.

Purpose The extant literature mainly focuses on the antecedents and outcomes of envy at the individual level. Workgroups have become ideal units for research on envy given the ubiquitous teamwork in organizations. This study aims to examine whether, how and when envy climate can influence group performance. Design/methodology/approach The authors analyzed data collected in three waves from a sample of 72 groups with 475 team members in full-service hotels in China. Findings Envy climate was negatively associated with group performance via intragroup relationship conflict. Furthermore, competitive climate moderated the effect of envy climate on intragroup relationship conflict and the indirect effect of envy climate on group performance through intragroup relationship conflict. Practical implications The present research offers organizations valuable insights into how to minimize the climate of envy and competition within a group and relieve the relationship conflict that may damage group performance. Originality/value Drawing on a social functional perspective of emotions, this study enriches the envy research by conceptualizing envy climate as a collective perception and clarifying its effect on group performance. The authors extend the understanding of envy climate by showing how a climate of envy embedded in a group influences group performance and also explain when group members may be more likely to act in a destructive way to respond to such a climate.

AbstractConflict is a ubiquitous feature of groups in organizations that clearly affects group performance. While prior research has investigated the role of personality on conflict resolution styles at the individual level, little work has examined the role of personality on the emergence of conflict. This may be partially due to the fact that the emergence of conflict is inherently a group-level phenomenon, and thus requires the aggregation of personality to the group (or at least dyadic) level of analysis. I propose that each of the Big Five personality traits (or specific facets), at the group level, affect the emergence of either task conflict, relationship conflict, or both. Developing our understanding of how group personality composition affects both of these types of conflict is necessary to better enable groups to manage conflict, and thereby lessen potentially harmful outcomes resulting from conflict.

In the era of personalized medicine, interindividual differences in the magnitude of response to an exercise training program (subject-by-training interaction; “individual response”) have received increasing scientific interest. However, standard approaches for quantification and prediction remain to be established, probably due to the specific considerations associated with interactive effects, in particular on the individual level, compared with the prevailing investigation of main effects. Regarding the quantification of subject-by-training interaction in terms of variance components, confounding sources of variability have to be considered. Clearly, measurement error limits the accuracy of response estimates and thereby contributes to variation. This problem is of particular importance for analyses on the individual level, because a low signal-to-noise ratio may not be compensated by increasing sample size (1 case). Moreover, within-subject variation in training efficacy may contribute to gross response variability. This largely unstudied source of variation may not be disclosed by comparison to a control group but calls for repeated interventions. A second critical point concerns the prediction of response. There is little doubt that exercise training response is influenced by a multitude of determinants. Moreover, indications of interaction between influencing factors of training efficacy lead to the hypothesis that optimal predictive accuracy may be attained using an interactive rather than additive approach. Taken together, aiming at conclusive inference and optimal predictive accuracy in the investigation of subject-by-training interaction entails specific requirements that are deducibly based on statistical principles but beset with many practical difficulties. Therefore, pragmatic alternatives are warranted.

This article investigates the association between, participation in, and exposure to voluntary organisations and marital fertility during the European fertility transition from 1880 to 1949. This is achieved using individual-level longitudinal demographic data from northern Sweden linked with individual-level information on voluntary organisation membership and contextual level information on organisation activity. How living near an organisation influenced fertility is measured using mixed effect Cox regressions. The association to participation for both men and women is tested by matching members to a control group through propensity score matching before estimating differences in risks of another birth using Cox regressions. The results show that being exposed to an organisation was related to lower fertility. Joining a union or a temperance organisation showed even stronger negative associations, but only for male members, while female members showed no significant difference in fertility. The results suggest that reproductive decisions were not simple responses by the individual couple to structural changes but were also shaped within the social networks of which they were a part.

Abstract Background: There is evidence that women with disabilities (WWDs) experience the most difficulty accessing and using sexual and reproductive health and rights (SRHRs) services and information worldwide. However, there are currently no workable interventions to reach WWDs with essential SRHR services. This study aims to test the effect of an integrated health facility and individual-level intervention on access to SRHRs information and services among sexually active WWDs aged 15-49years in Ghana. Methods: A quasi-experimental study design with four arms will be implemented in four districts in the Northern region of Ghana to test the effect of three inter-related interventions. The inventions are (1) capacity building in disability-centred SRHRs information and service delivery for healthcare providers, (2) support for WWDs to access disability-unfriendly healthcare infrastructure, and (3) one-on-one regular SRHRs education, information provision, and referral. The first two interventions are at the health-facility level while the third one is at the individual/family level. The first arm of the experiment will expose eligible WWDs to all three interventions. In the second arm, WWDs will be exposed to only the two-health facility-level interventions. The third arm will expose WWDs to only the individual level intervention. The forth arm will constitute the control group. A total of 680 (170 in each arm) sexually active women with physical disability and visual impairments will take part in the study over a period of 12months. To assess the effect of the interventions on key study outcomes (i.e. awareness about, and use of modern contraceptive, ANC attendance, and skilled delivery among parous women), pre- and post-intervention surveys will be conducted. Difference-in-Difference analysis will be used to examine the effect of each intervention in comparison to the control group, while controlling for effect modifiers. Cost-effectiveness analyses will also be conducted on the three-intervention arms vis a vis changes in key outcome measures to identify which of the three interventions is likely to yield greater impact with lower costs. Discussion: Lack of access to SRHRs information and services for WWDs is not only a violation of their right to appropriate and quality SRH care but could also undermine efforts to achieve equitable healthcare access as envisaged under SDG 3. This research is expected to generate evidence to inform local health programmes to increase access to SRHRs among WWDs by strengthening local health system capacity to provide disability-sensitive SRHRs services.
