Action strategies when avoiding two vertical obstacles
Bibliographic record
Abstract
Individuals inherently walk towards open spaces and avoid colliding with obstacles to reduce the risk of injury 1 . Research has demonstrated that young adults use body-scaled information to alter their movements when walking through confined spaces 2,3 . Young adults consistently require a safety margin greater than or equal to 1.3 times their shoulder width (termed Critical Point ) in order to pass through an aperture without changing their actions 2 . It is unknown as to whether individuals maintained similar body-scaled strategies when controlling their actions in situations where they are not obligated to walk through a confined space. The current study was designed to test the action strategies of young adults during an unconfined goal-directed locomotor task. The unconfined space consisted of a vertically oriented goal at the end of a 10m pathway and two vertically oriented obstacles placed half way (i.e. 5m from start) along the pathway on either side of the pathway's midline. The obstacles created an aperture that varied between 0.6-1.8 times each individuals shoulder width, but and allowed individuals to choose one of three possible pathways (middle, or around either obstacle). Individuals were instructed to walk to the goal at a natural pace and in a manner they felt was appropriate for success. No direct instructions were provided as to how to avoid the obstacles. Preliminary results indicate that young adults (N=12) chose to walk around the obstacles when the aperture was less than 1.4 times their shoulder widths (? 2 (7 ) = 58, p The ecological approach to visual perception.

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.
