Effects of familiarity on mothers' talk about nouns and verbs
Bibliographic record
Abstract
Modifications mothers make when talking to young English-speaking children between the ages of 1;8 and 3;0 (average age = 2;4) about words perceived to be familiar versus unfamiliar were investigated. Nineteen mothers and their children participated in two toy play tasks; one designed to elicit talk about familiar and unfamiliar animals and the other designed to elicit talk about familiar and unfamiliar actions. It was found that mothers' talk involving unfamiliar words differed from talk involving familiar words in a number of ways. Some modifications served to highlight the unfamiliar word which could assist in segmenting the unfamiliar word and mapping it to its referent. Compared to familiar nouns and verbs, unfamiliar nouns and verbs were produced more frequently in highly salient utterance positions and were paired more consistently with a clear nonverbal referent. Familiar nouns but, not verbs, were produced in longer utterances than unfamiliar nouns which could support the child's elaboration of the lexical representation of the familiar word.

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; a candidate call from one teacher head, not a consensus.
