Exploitation of perceptual information by 9.5 month old infants in search tasks
Bibliographic record
Abstract
The relationship between object-knowledge and goal-directed action is critical to understanding cognitive development in the first year of life. Examining the organization of action, perception and cognition in 9.5-month-old infants, the current study first investigates the effects of manipulating perceptual information when searching for a goal-object by coordinating abi-directional detour reach around transparent, opaque and 50%-graded occluders to obtain a goal-object. Second, the study explored how changes in cognitive complexities via a manipulation to the number of hiding-locations (three-vs.five-) affect infants' problem-solving abilities. Results demonstrate infants' impressive ability to initiate a mental plan of action and subsequently execute appropriate motor actions. Infants' search benefited most when the object was visible through the occluder and some information about the occluder's solidity was provided. The findings support the lack of memory-inhibition accounts (Diamond, 1991) and shed light onto previously unexamined elements of perceptual-cognitive development during the first year of life.

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.
