| Outline of Final Research Achievements |
Some individuals automatically and involuntarily “see” mental images of numbers in spatial arrays when they think of numbers (number forms). Makioka (2009) proposed a theoretical framework called self-organizing learning account of number forms (SOLA), which argues that number forms are generated by self-organizing learning between numerical and spatial representation. This framework explains three features of number forms: (a) within-individual consistency, (b) between-individual variation, and (c) mixture of regularity and randomness.
This study aims to examine whether SOLA can explain the interaction between numerical and spatial representations in non-synaesthetes. Participants viewed pairs of numerals and reported vocally which numeral was larger. There were significant between-individual variation and irregularity in the spatial configurations induced from RT distribution. These results suggest that self-organizing learning occurs between numerical and spatial representation.
