Studies on aging and migration often note a ‘language barrier’ for older migrants when communicating in a (medical) second language (L2) context. Yet how a limited L2 proficiency impacts the aging process of migrant adults has, so far, not been systematically investigated. This question is important given that having a limited L2 proficiency may pose immediate drawbacks on one's ability to maintain independence. Through a combination of qualitative interviews and quantitative language and cognitive measures, this study investigates if and under which circumstances a ‘language barrier’ may be detrimental for the aging process of a group of older female Turkish migrants in the Netherlands. Findings suggest that a limited L2 proficiency reciprocally fuels feelings of L2 insecurity, which impacts the formation of social relationships in the L2, feelings of belonging and lower wellbeing levels. A firm embedding in an L1 network positively impacts wellbeing levels, yet results in a heavy dependence on others in L2 situations. We conclude that limited L2 skills may steer the aging process in a detrimental direction for those older migrants who lack a social support network in the L1 and cannot communicate effectively in the L2.

Cognitive advantages for bilinguals have inconsistently been observed in different populations, with different operationalisations of bilingualism, cognitive performance, and the process by which language control transfers to cognitive control. This calls for studies investigating which aspects of multilingualism drive a cognitive advantage, in which populations and under which conditions. This study reports on two cognitive tasks coupled with an extensive background questionnaire on health, wellbeing, personality, language knowledge and language use, administered to 387 older adults in the northern Netherlands, a small but highly multilingual area. Using linear mixed effects regression modeling, we find that when different languages are used frequently in different contexts, enhanced attentional control is observed. Subsequently, a PLS regression model targeting also other influential factors yielded a two-component solution whereby only more sensitive measures of language proficiency and language usage in different social contexts were predictive of cognitive performance above and beyond the contribution of age, gender, income and education. We discuss these findings in light of previous studies that try to uncover more about the nature of bilingualism and the cognitive processes that may drive an advantage. With an unusually large sample size our study advocates for a move away from dichotomous, knowledge-based operationalisations of multilingualism and offers new insights for future studies at the individual level.

In an attempt to explain first language attrition in emigrant populations, this paper investigates the explanatory power of a framework that has – until now – received little attention: the regression hypothesis (Jakobson, 1941). This hypothesis predicts that the order of attrition is the reverse of the order of acquisition. The regression hypothesis was tested in relation to the loss of morphology and syntax in Dutch immigrants in Anglophone Canada. Evidence in favor of regression was found, but mainly in the morphological domain. Syntax, on the other hand, was mostly characterized by L2 influences from English. As it is problematic to treat regression as a theory in its own right, these findings are then explained in the light of both generative and usage-based approaches, as well as the more recent Dynamic Systems Theory.

Bilingualism has been put forward as a life experience that, similar to musical training or being physically active, may boost cognitive performance and slow down age-related cognitive decline. In more recent years, bilingualism has come to be acknowledged not as a trait but as a highly individual experience where the context of use strongly modulates any cognitive effect that ensues from it (cf. van den Noort et al., 2019). In addition, modulating factors have been shown to interact in intricate ways (Pot, Keijzer and de Bot, 2018). Adding to the complexity is the fact that control processes linked to bilingualism are bidirectional—just as language control can influence cognitive control, individual differences in cognitive functioning often predict language learning outcomes and control. Indeed, Hartsuiker (2015) posited the need for a better understanding of cognitive control, language control as well as the transfer process between them. In this paper, we aim to shed light on the bidirectional and individual cognitive, social and linguistic factors in relation to bilingualism and second language learning, with a special focus on older adulthood: (1) we first show the intricate clustering of modulating individual factors as deterministic of cognitive outcomes of bilingual experiences at the older end of the lifespan; (2) we then present a meta-study of work in the emergent field of third-age language learning, the results of which are related to lifelong bilingualism; (3) objectives (1) and (2) are then combined to result in a blueprint for future work relating cognitive and social individual differences to bilingual linguistic outcomes and vice versa in the context of third-age language learning.

This study addresses a gap in the literature on executive function advantages among bilingual speakers by investigating a group of elderly, long-term, immersed bilinguals. Our participants are native Dutch speakers who emigrated to Australia as adults and have spent many years in that country. They are compared on a range of cognitive and linguistic measures to native Dutch and native English control groups. We argue that, due to the massive differences in the bilingual experience, group analyses may fall short of capturing the full picture. We argue instead for a more qualitative approach, which takes into account as detailed a picture of bilingual development, daily language habits and, in particular, code-switching habits as possible.

The study explores the effects of teacher support and student cohesiveness on foreign language (FL) learning outcomes and compares their effect with that of FL anxiety. One hundred and forty-six first-year Chinese undergraduates of Japanese, who were also learning English, participated in two surveys that were administered over a 2-month interval. Data were collected using the Foreign Language Classroom Anxiety Scale (Horwitz, Horwitz, & Cope, 1986), the Teacher Support Scale (Trickett & Moos, 2002), the Affiliation Scale (Trickett & Moos, 2002), the English Proficiency Scale, and the Japanese Proficiency Scale. It was found that (a) student cohesiveness was a positive predictor of FL proficiency, (b) teacher support, which was positively related to student cohesiveness and negatively to FL anxiety, did not show a direct relationship with FL proficiency, and (c) FL anxiety, which was negatively associated with FL proficiency, showed a better predictive power than student cohesiveness and teacher support.
