Tight vs. loose fit in containment events by the model compared with humans. (A) Containment 'tightness' is measured by the ratio between the length of the common border (along the internal boundary of the container) shared with the inserted object, and the length of the entire internal boundary. A ratio close to 1 (similar lengths) indicates a ‘tight’ fit, while a low ratio indicates a ‘loose’ fit (B) The judgments of ‘loose’ and ‘tight’ fit produced by the model are correlated (R² = 0.51) with the judgements of five human subjects, suggesting that the manner in which the algorithm extracts and uses boundary information from visual cues, is similar to humans’ 'tightness' judgement.
