IQ heritability increases during early childhood, but it is unclear whether it stabilizes thereafter. [14] A 1996 statement by the American Psychological Association gave about 0.45 for children and about .75 during and after adolescence . [ 15 ]

A 2012 study of more than 6,000 Brits born in 1958 found a link between high IQ in childhood and the use of ... that reading from an early age increases both verbal and nonverbal (e.g. reasoning ...
When IQ testing was first created, Lewis Terman and other early developers of IQ tests noticed that most child IQ scores come out to approximately the same number regardless of testing procedure. Variability in scores can occur when the same individual takes the same test more than once.
A recent theory suggests that early childhood stress may affect the developing brain and cause negative effects. [47] Exposure to violence in childhood has been associated with lower school grades [48] and lower IQ in children of all races. [49]
