ab: Summary: For more than 30 years, it has been admitted that individuals from
the age of 10 mainly retrieve the answer of simple additions from
long-term memory, at least when the sum does not exceed 10.
Nevertheless, recent studies challenge this assumption and suggest that
expert adults use fast, compacted and unconscious procedures in order
to solve very simple problems such as $3+2$. If this is true, automated
procedures should be rooted in earlier strategies and therefore
observable in their non-compacted form in children. Thus, contrary to
the dominant theoretical position, childrenâ€™s behaviors should not
reflect retrieval. This is precisely what we observed in analyzing the
responses times of a sample of 42 10-year-old children who solved
additions with operands from 1 to 9. Our results converge towards the
conclusion that 10-year-old children still use counting procedures in
order to solve non-tie problems involving operands from 2 to 4.
Moreover, these counting procedures are revealed whatever the expertise
of children, who differ only in their speed of execution. Therefore and
contrary to the dominant position in the literature according to which
childrenâ€™s strategies evolve from counting to retrieval, the key
change in development of mental addition solving appears to be a shift
from slow to quick counting procedures.
