Hand Preference in Children’s Referential Gestures During Storytelling: Testing for Effects of Bilingualism, Language Ability, Age, and Sex
Bibliographic record
Abstract
Adults, preschool children, and infants gesture more with their right hand than with their left hand. Since gestures and speech are related in production, it is possible that this right-hand preference reflects left-hemisphere lateralization for gestures and speech. The primary purpose of the present study was to test if children between the ages of 6 and 10 years show a right-hand preference in referential gestures while telling a story. We also tested four predictors of children’s degree of right-hand preference: 1) bilingualism, 2) language proficiency, 3) age, and 4) sex. Previous studies have shown that these variables are related to the degree of speech lateralization. Twenty-five English monolingual (17 girls; M age = 8.0, SD age = 1.4), 21 French monolingual (12 girls; M age = 7.3, SD age = 1.4,) and 25 French-English bilingual (11 girls; M age = 8.5, SD age = 1.4) children watched a cartoon and told the story back. The bilinguals did this once in each language. The referential gestures were coded for handedness. Most of the participants showed a right-hand preference for gesturing. In English, none of the predictor variables was clearly related to right-hand preference. In French, the monolinguals showed a stronger right-hand preference than the bilinguals. These inconsistent findings across languages raise doubts as to whether the right-hand preference is linked to lateralization for speech.

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.
