“…Connections between neurons within a network can become strengthened as that network is repeatedly engaged, which modifies the proteins and enzymes along neural synapses. Neural connectivity can increase (or decrease) as the number of postsynaptic dopamine receptors in the mesocorticolimbic system change, neurotransmitter production is modified, synapses become enlarged, and/or dendritic spines grow on the postsynaptic neuron to increase the contribution of incoming information ( Bliss et al, 2003 ; Nithianantharajah and Hannan, 2011 ; Freret et al, 2015 ; Blackburn, 2019 ; Iaccarino et al, 2020 ). Another possibility is that by engaging in tasks that require a high degree of cognitive effort, neural pathways for performing specific cognitive tasks are reorganized in a way that is more efficient and demands less resources ( Bialystok et al, 2007 ; Woumans et al, 2015 ).…”

We first provide a critical review of the existing findings on bilingualism as a contributor to cognitive reserve from moderator-mediator warranting cause-effect research conclusions. We next address the question of direct or indirect effects between bilingualism and neurocognitive protective factors influencing the associated age-related mental deficits. The existing findings support bilingualism as a predictor and as a moderator. Third, we propose cognitive reserve models of bilingualism describing analytical approaches that allow testing of these models and hypotheses related to path strength and causal relationships between predictors, moderators, and mediators. Lastly and most importantly, we suggest using large datasets available via open repositories. This can aid in the testing of theoretical models, clarifying the roles of moderators and mediators, and assessing the research viability of multi-causal paths that can influence cognitive reserve. Creating collaborative datasets to test these models would greatly advance our field and identify critical variables in the study of the bilingual aging brain.

This entry provides an overview of multilingualism and world Englishes. The entry begins with a description of the multilingual context by discussing multilingualism as a global phenomenon and consider various language hierarchies. The entry then proceeds to a discussion of code‐switching/mixing, domains of use and multilingual repertoires, which is followed by a review of research on multilingualism from a world Englishes perspective. The entry then presents data from a case study investigating the linguistic networks of a polyglot multilingual South African student, which serve to illustrate many of the points made in the entry.
