The process by which this transformation occurs remains debated. Here, we propose a computational model\u00a0of human quantity estimation which synthesizes four general concepts established over the history of\u00a0cognitive science:\u00a0(1)\u00a0nonsymbolic quantity representations;\u00a0(2)\u00a0a general\u00a0capacity\u00a0for comparative judgment;\u00a0(3)\u00a0associative memory; and\u00a0(4) an\u00a0anchoring\u2010and\u2010adjustment mechanism.\u00a0We tested model predictions in preregistered experiments where participants estimated briefly displayed dot arrays. The model reproduced key psychophysical signatures of human quantity estimation across stimulus durations (100, 500, and 1000 ms) and replicated human calibration effects induced by exposure to veridical reference quantities. The results suggest that the psychophysics of symbolic estimation observed in humans can be explained by an extension of the evolutionarily ancient capacity for quantity discrimination.<\/jats:p>","DOI":"10.1111\/cogs.70256","type":"journal-article","created":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T17:18:21Z","timestamp":1787851101000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Quantity
