Chrysostomou, Marilena; Pitta-Pantazi, Demetra; Tsingi, Chara; Cleanthous, Eleni; Christou, Constantinos – Educational Studies in Mathematics, 2013
Recently, a new cognitive style approach was introduced, which refers to two types of visualizers. This approach is based on neuropsychological evidence and neuroimaging results, which suggest the existence of two distinct imagery subsystems, the object and the spatial imagery subsystems. The goal of the study was twofold: first to examine a…
