The Impact of Synchronized Tactile Stimulation on Joint Attention in 11-Month-Old Infants
Bibliographic record
Abstract
Infants explore the world through many combinations of sight, sound, smell, taste and touch. A recent theory known as the “intersensory redundancy hypothesis” posits that the temporal overlap of stimulation across different sense modalities drives selective attention in infancy. Social communication typically involves visual, auditory and tactile cues for infants. Although infrequently studied, rhythmic touch is thought to be inherently rewarding; if manipulated within a social context, it may be able to reinforce joint attention. Given that joint attention is fundamental to the development of social communication, this study investigated the convergent effects of visual, auditory and tactile cues on the expression of joint attention in 10 infants between 11 to 12 months of age. The addition of synchronized (but not asynchronous) tactile stimulation to natural communication cues was associated with higher performance on a joint attention measure (i.e. more frequent responses to parental requests). Implications for autism are discussed.

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.
