Age-Specific Changes in IQ:
Impact of Childhood IQ on Later Life:
Research indicates that while childhood IQ tends to be relatively stable and predictive of various adult outcomes, significant changes can occur, particularly in relation to mental health. Declines in IQ during childhood are linked to higher risks of psychotic symptoms and schizophrenia. Additionally, higher childhood IQ is associated with better health outcomes and lower mortality rates in adulthood. Understanding these dynamics can help in early identification and intervention for at-risk individuals.
