Peri-hand space: A helping hand for faster object recognition in children.
Bibliographic record
Abstract
Visual processing is altered for stimuli located near the hands, in what is termed peri-hand space, but it is unclear whether peri-hand effects are stable across the lifespan. To investigate this, adults and 5- to 8-year-old children completed a naturalistic visual search task on a touchscreen monitor while wearing eye-tracking glasses. Upon recognizing a previously specified target image in a 12-image array, they released a pushbutton with their left index finger in order to reach out and touch the target. Participants completed the task twice, once with their right hand positioned on the monitor beside the visual array and once with their right hand positioned in their lap. Both children and adults were faster at recognizing the target when their right hand was near the array, but the magnitude of this peri-hand effect was greater in children than adults. The results are discussed in relation to the idea that object recognition may be facilitated within peri-hand space to a greater extent during childhood.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
