TL;DR: This article examined the role of general inhibitory control and general set shifting processes in bilingual language production in 51 native Finnish speakers with English as L2, mainly learnt after the age of 7.

TL;DR: In this article, a large-scale pre-registered randomized controlled trial (n = 255) used a 4-week adaptive working memory training with a single digit n-back task.

TL;DR: This paper examined the relationship between self-reported everyday language switching experience and the performance of early bilinguals in tasks measuring different executive functions and concluded that these results likely reflect individual differences in executive skills, and do not provide evidence for the hypothesis that language switching trains executive functions.

TL;DR: Group differences supporting theBEA hypothesis were limited only to the n-back composite, and this composite was not predicted by bilingualism-related features, and Bayesian analyses did not give consistent support for the BEA hypothesis.

TL;DR: In this paper, the authors present two externalistic adaptations of psychological placeholder essentialism, a strict externalist and a hybrid externalist view, which are experimentally testable, and conclude that lay speakers’ natural kind concepts involve a belief in an external category essence, which determines reference.
