    "abstract": "Evidence suggests that general, non-mathematical knowledge\nabout the entities described in an arithmetic word problem may\ninterfere with its encoding. We used behavioral and eye-\ntracking measures to investigate how the use of specific\nquantities may foster a cardinal representation of the numbers\nmentioned in a problem, whereas other quantities may favor an\nordinal representation instead. We asked 50 pre-service\nteachers to complete a solution validity assessment task. We\ncompared participants’ gaze patterns on isomorphic problems\nto gather insights into their encoded representations. On\nproblems featuring cardinal quantities, we found that specific\nsentences describing elements relevant in a cardinal\nunderstanding of the problems but irrelevant otherwise were\nlooked at longer and were the focus of a higher number of\nbackward eye movements. Additionally, an increase in pupil\ndilation on correctly solved cardinal problems supported the\nidea that participants need to engage in a recoding process\nwhen facing semantic incongruence.",
