Abstract
The acquisition and conceptualization of spatial knowledge are important topics in human spatial cognition. At the global scale, maps are our primary graphic source of information; however, they distort the size and shape of geographic features. If a distorted reference is used and the reader assumes it to be accurate, it may inappropriately influence decision making and, possibly, the shape of our global-scale cognitive maps. This paper examines trends in perception of land area, using equal-area and non-equal-area references, as well as investigating how map-projection knowledge can influence interpretation of land area. Results from the land-area studies show that map readers attempted compensation for projection distortion only when using the Mercator projection as a reference, and only for certain regions displayed on the Mercator projection. For other reference materials there is no attempted compensation for perceived distortion, even when participants believe that the reference is distorting land area. It is also apparent that most participants have limited projection knowledge and have difficulty transferring this knowledge to other projections or to practical application tasks. Both of these findings have implications for understanding perceptual issues in map reading and for determining where distortions can be introduced at the encoding stage of cognitive map development.

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
