Abstract
En este trabajo analizamos el carácter funcional del conteo en la resolución de tareas de correspondencia uno-a-uno, orden y cardinalidad. Para ello, se presentan dos situaciones, de conteo y de no-conteo, a 72 sujetos con edades comprendidas entre 4,4 y 8,3 años. Los resultados muestran que a pesar de que todos los niño son capaces de contar correctamente los conjuntos presentados, no son igualmente capaces de aprovechar la información aportada por el conteo para resolver las tareas que se les proponen. En efecto, cuanto menor es la edad de los niños, mayor es su tendencia a emplear procedimientos alternativos, como, por ejemplo la correspondencia uno-a-uno y los indicios perceptivos.
In this work we analyse the functional value of counting to solve one-to-one correspondence, order, and cardinality tasks. To this end, we presented two situations, counting and not-counting, to 72 subjects whose ages ranged from 4 years 4 months to 8 years 3 months. Results showed that in spite of children's ability to correctly count the sets proposed, they were not equally able to benefit from the quantitative information provided by counting when solving the tasks that they were presented. In efect, as children's ages decrease their inclination to employ alternative procedures increase, such as, for instance, the one-to-one correspondence and the perceptual evidence.
