Introduction:
The neuroconstructivist approach studies early childhood comparative development from an interdisciplinary and neuropsychological perspective in order to relate neurological architecture to cognitive functioning.
Aim:
Logical development and resistance to interference as a component of executive functions are studied comparatively in typical babies and twins born with weight discordance to analyze its effects on development, learning and behaviour control.
Subjects And Methods:
The task's resolution is registered when babies are 18, 21 and 24 months of age. Microgenetic and multivariate analysis compares, on the one hand, 48 typical babies to growth discordant twins and, on the other, 32 twins to one another.
Results:
Intergroup task resolution is similar with regard to logical development in both groups under analysis but resistance to interference is lower in growth discordant twins than in typical babies and, when twins are compared to one another, twins with lower weight show more difficulties regarding logical resolution.
Conclusion:
Twin babies show less resistance to interference than typical babies and similar but delayed in time logical functioning.
