Approximately 10% of babies worldwide are born prematurely — before 37 weeks of gestation. For parents of preterm infants, particularly those born very early, a pressing question is: how will prematurity affect my child’s cognitive development? Research spanning decades and tens of thousands of preterm-born individuals now provides a clear, …
Can You Actually Increase Your IQ? What the Research Shows
Few questions in psychology generate as much debate as whether intelligence is fixed or malleable. The idea that IQ is set in stone — hardwired by genetics and sealed by early childhood — persists in popular culture, but the scientific picture is considerably more nuanced. Decades of research show that …
