Research suggests that a young child’s brainwave activity at rest may predict their intelligence later in life.
A follow up study done in the United States and Germany to the famous Romanian study, (early 2000’s) has shown for the first time, that a child’s upbringing may impact their brainwave power capacity years down the road. It claims that an individual’s resting brain behavior remains fairly stable throughout life, even though there is a fluctuation in power as we age. But what is in question is how the resting brain activity in early childhood is manifested and understood.
As a typical healthy child grows to age 10, a resting brain activity has fewer lower frequency or slower wave forms and a higher amount of faster brain waves or higher-frequency waves.
When lower frequency brain waves are found during the rest it is often associated with “neural pruning”, a way the brain makes stronger neural connections through reducing unnecessary ones. This important step makes the brain more efficient at different mental tasks and critical to a child’s cognitive development. Too much, too little or too long in the pruning stage can be harmful to a child’s brain. It is thought that a lack of emotional support along with not enough cognitive stimulation at an early age, will show up in less cognitive development, which may possibly be impacted by the neural pruning process.
An assessment of IQ of 202, 18-year-olds enrolled in the Bucharest study, showed those with the lowest test scores tended to also have the slower brainwaves as toddlers. These findings along with others, suggested a correlation to longer-term cognitive changes later in life.
The Bucharest Early Intervention Project (BEIP) stands as a groundbreaking study that has transformed our understanding of early childhood development and its long-term impact on cognitive abilities. The study delved into the brain wave activity of toddlers and its potential in predicting IQ at 18 years of age. Over the course of several decades, BEIP explored the cognitive abilities of children raised in foster care, institutionalized settings, and home care, revealing crucial insights into the effects of early life experiences on future intelligence.
The Bucharest Early Intervention Project (BEIP):
The BEIP was initiated in the early 2000s with the primary goal of investigating the effects of early institutionalization on children’s cognitive development. Researchers focused on children from Romanian orphanages, where they experienced either institutional care or were placed into foster care. The study followed these children from toddlerhood to early adulthood, gathering an extensive dataset of brain wave activity and cognitive assessments at various stages of their lives.
Findings of the BEIP:
-
Brain Wave Activity Predicting IQ: One of the most intriguing findings of the BEIP was the potential of brain wave activity in toddlers to predict their IQ at 18 years of age. Using electroencephalogram (EEG) recordings, researchers identified distinct patterns of brain waves in children who eventually displayed higher IQ scores at 18. This discovery highlighted the significance of early neural development in shaping later cognitive abilities.
-
Institutionalization vs. Foster Care: Comparing the cognitive abilities of children raised in institutionalized settings with those in foster care revealed stark differences. Children placed in foster care showed notable improvements in IQ scores and cognitive functions compared to their counterparts in institutions. The enriched and nurturing environment provided by foster care played a critical role in mitigating the detrimental effects of early institutionalization.
-
Home Care’s Advantage: Perhaps the most compelling revelation was the superior cognitive development of children who grew up in home care environments from an early age. These children demonstrated higher IQ scores and sharper cognitive skills, emphasizing the crucial role of stable and supportive family environments during the early formative years.
Current Understanding and Implications: Over the years, the BEIP findings have paved the way for a deeper comprehension of the neurobiological underpinnings of intelligence and the long-lasting effects of early experiences. The study’s longitudinal nature allowed researchers to recognize the brain’s remarkable plasticity during early childhood, as well as its vulnerability to adverse environments.
Today, we have a more profound appreciation for the importance of early interventions and the significance of stable caregiving in fostering optimal brain development. The BEIP has also highlighted the necessity of policies aimed at improving the quality of institutional care and supporting vulnerable families to provide nurturing environments for their children.
While the correlation between toddler brain wave activity and IQ at 18 is evident, we still need more research. It is essential to note that intelligence is a complex trait influenced by various factors, including genetics, nutrition, education, and environmental experiences beyond early childhood.
Unearthing essential insights into the relationship between early childhood experiences and cognitive development is an important area of study. Findings have underscored the need for investment in early childhood education and the creation of supportive environments for children, particularly those at risk of adverse experiences. As we continue to build upon the knowledge gleaned from this monumental study, we have the opportunity to shape brighter futures for the next generation, one brain wave at a time.
