Abstract
When people experience VR for the first time they reach out in an attempt to see their own hands in order to manipulate objects in the virtual environment. In the real world, the space where people are able to physically manipulate objects is referred to as peripersonal space whereas extrapersonal space is any physical area that is beyond the observer's arm's reach. Gamberini, Carlesso, Seraglia, and Craighero (2013) examined how people perform a line bisection task in VR and suggested that a tool's action consequence (i.e., the result of using a tool on an object in a virtual environment) affects how people perceive extrapersonal and peripersonal space. Gamberini et al. reported that when a tool was perceived as a "cutter" because it cut a to-be-bisected virtual line into two segments, the tool effectively extended the boundaries of peripersonal space as it allowed the observer to directly interact with lines that were in extrapersonal space. If, however, the tool was simply a "pointer" (i.e., did not break a virtual line into two segments on a line bisection task), then the separability of peripersonal and extrapersonal space remained intact.

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 it
