RT journal article T1 Informal Mathematical Thinking: Invariance of the Role of Domain-General and Domain-Specific Precursors in Spain and Chile A1 Cerda, Gamal A1 Pérez, Carlos A1 Chandía, Eugenio A1 Aragón Mendizábal, Estívaliz Lorena A1 Navarro Guzmán, Francisco José Ignacio A2 Psicología K1 early numeracy K1 symbolic comparison K1 cognitive predictors K1 preschool education K1 cross-cultural study K1 structural equation modeling K1 domain-general skills K1 domain-specific skills AB This study examines how domain-general (processing speed and receptive vocabulary) and domain-specific (symbolic and non-symbolic comparison) cognitive skills contribute to early informal mathematical thinking in preschoolers. The aim was to assess the invariance of these predictive relationships across two sociocultural contexts: Chilean and Spanish samples. A total of 130 children participated, and structural equation modeling was used to estimate latent structures and test multigroup invariance. The results revealed a consistent latent structure across samples and a significant contribution of symbolic and non-symbolic comparison to early math performance, while processing speed and vocabulary showed context-specific variations. These findings indicate that although foundational mathematical competencies rely on common cognitive mechanisms, cultural and educational contexts modulate the strength of these associations. This study contributes to understanding the cognitive architecture underlying early numeracy and highlights the importance of culturally sensitive assessment and intervention strategies.
