Learning English as a second language during childhood: A \nlongitudinal case study
Bibliographic record
Abstract
Since the 1950s, hypotheses have been put forth to explain developmental behaviours \nobserved during a learner’s second language (L2) acquisition. Many of these \nhypotheses build on language transfer, which provides a basis for the explanation of \nmany phenomena that learners exhibit during the acquisition of their L2. However, \naspects of transfer have yet to be fully understood; among others, how the critical period \nfor language acquisition affects the relationship between a learner’s first language (L1) \nand L2 has yet to be unfolded. \nTransfer effects and the critical period are indeed potentially confounded when the L2 \nlearner is a child. Furthermore, three questions surrounding transfer still remain. These \nquestions are as follows: What is transferred? What are the conditions for transfer? And \nwhen does transfer occur? Further, while it is commonly observed that children are more \nproficient than adults at language learning, debates still exist as to whether or not a \ncritical period for language acquisition exists at all. In relation to this, there is also the \ndebate concerning whether children introduced to an L2 early in life behave more like a \nfirst or second language learner for that L2. \nThis thesis describes a longitudinal corpus documenting a child named Nura, who is a \nL2 learner of English with Kazakh as her L1 (also with some passive knowledge of \nChinese). More specifically, we focus on Nura’s development of singleton onsets and \nonset clusters which do not occur in her native Kazakh language. The data provides \nevidence for relatively immediate transfer effects through her early acquisition of her \nsingleton onsets and onset clusters. However, the developmental patterns of a number \nof sounds and sound combinations also point to issues in child L2 development in \ncontexts where transfer is not possible, if only for certain phonological dimensions of the \nL2.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
