“…Researchers have started to explore children's spontaneous tendency to focus on mathematical aspects other than numerosity, including number symbols (SFONS; Rathé, Torbeyns, De Smedt, & Verschaffel, 2019) and quantitative relations (SFOR; Degrande, Verschaffel, & Van Dooren, 2017;McMullen, Hannula-Sormunen, & Lehtinen, 2014). Some researchers suggested the existence of a Spontaneous Focus On Patterns (SFOP) tendency and its role in early mathematical development (Mulligan et al, 2018;Sarama & Clements, 2009;Sharir, Mashal, & Mevarech, 2015;Verschaffel et al, 2018Verschaffel et al, , 2017. The current study focuses on this SFOP concept, which can be described as the tendency to spontaneously look for, notice, or create patterns.…”
