Early Advanced Development = Higher IQ? What Studies Say

Based on five studies, the findings are that the developmental rate in infancy may not mean much.

Children with higher IQ scores (more than 140) at age 4 did not develop more quickly than others during infancy. 

Precocious preschooler readers do not necessarily have extraordinary reading abilities and related skills in their middle elementary school years. Moreover, some highly intelligent children do not read early and some precocious readers are of average or even subnormal intelligence.

Mathematics ability in preschool years does predict math achievement through to age 15, and growth in mathematical ability between age 54 months and first grade is an even stronger predictor of adolescent mathematics achievement.
