Abstract

Fundamental advances in neuroscience have come from investigations into neuroplasticity and learning. These investigations often focus on identifying universal principles across different individuals of the same species. Increasingly, individual differences in learning success have also been observed, such that any seemingly universal principle might only be applicable to a certain extent within a particular learner. One potential source of this variation is individuals' genetic differences. Adult language learning provides a unique opportunity for understanding individual differences and genetic bases of neuroplasticity because of the large individual differences in learning success that have already been documented, and because of the body of empirical work connecting language learning and neurocognition. In this article, we review the literature on the genetic bases of neurocognition, especially studies examining polymorphisms of dopamine (DA)-related genes and procedural learning. This review leads us to hypothesize that there may be an association between DA-related genetic variation and language learning differences. If this hypothesis is supported by future empirical findings we suggest that it may point to neurogenetic markers that allow for language learning to be personalized.

  • Genetically encoded dopaminergic reception and transmission mediate the acquisition of procedural aspects of grammar.

    “A neurogenetic approach to individual differences in L2 learning is advanced by Wong et al. (2012), who specify the mediating roles of genetically encoded dopaminergic (DA) reception and transmission that underlie the acquisition of procedural aspects of grammar.”

    From Plasticity, Variability and Age in Second Language Acquisition and Bilingualism (2018) · cites this paper as Wong et al. (2012)

    The Introduction links genes encoding dopamine receptors and transporters to procedural learning and proposes that DA-related genes may be associated with variation in grammar learning. The Counter-Evidence and Other Challenges section likewise calls the gene–grammar link a hypothesis limited to some aspects of grammar learning. The claim overstates this proposed relationship as an established mediating mechanism. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Individuals with different genetic profiles may have different learning capabilities, with more variation expected in adult L2 acquisition than in L1 acquisition.

    ““it is not surprising that individuals with different genetic profiles may have different learning capabilities” (Wong et al., 2012, p. 1093), with more variation expected in adult L2 acquisition than in L1 acquisition.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
