Análise da aquisição de comportamento verbal em uma criança dos dezoito meses aos dois anos de idade
Bibliographic record
Abstract
The purpose of the present study is to investigate the acquisition of verbal behavior in a longitudinal research with a typical development child from eighteen months of age until two years old, adopting as unit of analysis Skinner´s (1957) verbal operants.The aim of the present work is to analyze verbal responses emitted by the child and the caretakers in a natural setting in terms of verbal operants and try to identify relations between the emission of operants by caretakers and the child, investigating possible interaction patterns in the acquisition of verbal behavior.Thirty four sessions of fifteen minutes of duration were registered per week and then transcript.Data were analyzed based upon categories created from Skinner´s verbal operants (1957).Results show a rapidly increase in the emission of tact, mand, echoic and intraverbal categories of the participant after twenty months of age.This increase also happened simultaneously in the emission of the same categories of the caretaker.The most emitted category of the child was the tacts, while the most emitted category by the caretaker was the mands.

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.
