Assessing Toddlers' Cross-situational Word Learning on an Online Research Platform
Bibliographic record
Abstract
Our previous work has shown that young children rapidly learn new words by tracking their co-occurrence with objects across multiple, "cross-situational" exposures on a computer screen. However, little is known about the representational status of these newly acquired words. Thus, in this study, we use a generalization test to investigate whether 2- to 3-year-olds acquire sufficiently abstract representations for the new words and extend them to different versions of the named objects. This research will help us better understand the mechanisms underlying early word learning.

How this classification was reachedexpand
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; both teacher heads agree on what is shown here.
