Childhood Theta Brainwave Activity Predicts IQ at Age 18
Resting brain activity observed during early childhood, specifically in the theta frequency band, has been found to predict cognitive outcomes and IQ at age 18, according to a study published in Developmental Cognitive Neuroscience. The research, conducted on a sample of 202 children, suggests that variations in resting brain activity during critical developmental periods can provide insights into long-term cognitive trajectories. The study also found that experiences like institutional rearing and the timing of foster care placement had significant effects on cognitive development, with resting theta power acting as a mediator between these experiences and long-term cognitive outcomes. However, further research is needed to understand the underlying mechanisms behind these associations.
