SFON is known to be a significant predictor of mathematical skills development. This study is the first one to implement eye-tracking to study SFON. The aim of the present research is to investigate the relations between young children’s SFON and their eye movement behaviour during memory card game. The results did not reveal significant differences between how many times participant had fixated on objects they did or did not enumerate. However, the extensive variation in the number of fixations on the enumerated objects suggests distinct enumeration strategies between subitizing- and counting-based enumeration.8enginfo:eu-repo/semantics/openAccessPsychologyEducational sciencesConference articleopenAccessfcbf3bdb-c18f-4b7d-9bb4-d55de354ce75105013565844
