Normal IQ Level of Children
Understanding Childhood IQ Levels
Average IQ Scores in Children
The average IQ score for children is typically around 100, which is considered the median score on standardized IQ tests. This is supported by research where children with an average IQ had a mean score of approximately 100.8. This score represents the central point of the IQ scale, where most children fall within the range of 85 to 115, which is considered the normal range for IQ scores.
IQ Variations Based on Environment
Environmental factors play a significant role in the IQ levels of children. Studies have shown that children growing up in orphanages tend to have lower IQ scores compared to those raised in family settings. Specifically, children in orphanages had an average IQ of 84, while their peers in family environments had an average IQ of 104, indicating a 20-point difference. This suggests that the environment, including the quality of care and stimulation, can significantly impact a child's intellectual development.
Influence of Socioeconomic Status
Socioeconomic status (SES) also influences children's IQ scores. Research indicates a positive correlation between SES and IQ, with children from middle or upper-class families often scoring higher on IQ tests. This is attributed to greater verbal stimulation and encouragement of language skills in higher SES families. The correlation between parental IQ and child IQ further supports the influence of both genetic and environmental factors on intelligence.
IQ Stability and Changes Over Time
While IQ is generally stable, certain conditions can lead to changes over time. For instance, children born preterm have shown a decline in IQ scores from childhood to adolescence, even in the absence of clear neurological damage. This decline is associated with specific brain regions, such as the parietal and temporal lobes. This highlights the potential for IQ changes due to subtle brain abnormalities that may not be immediately apparent.
Impact of Learning Disabilities
Children with learning disabilities (LD) often have IQ scores within the low-average to high-average range but exhibit specific cognitive deficits. These deficits are evident in areas such as number comprehension, arithmetic skills, and working memory, which are not solely explained by their IQ scores. This indicates that while IQ provides a general measure of cognitive ability, it does not capture all aspects of intellectual functioning, especially in children with LD.
Parental Reactions to IQ Scores
Parents' reactions to their children's IQ scores can vary significantly. Parents of children with average IQ scores (mean IQ = 100.8) often have less accurate memories of the test results and experience fewer positive consequences compared to parents of children with above-average IQ scores (mean IQ = 130.0). This suggests that psychological support may be beneficial for parents of children with average IQ scores to help them better understand and support their child's development.
Conclusion
The normal IQ level for children typically falls within the range of 85 to 115, with an average around 100. Environmental factors, socioeconomic status, and specific conditions such as preterm birth or learning disabilities can influence these scores. Understanding these influences can help in providing better support and interventions to optimize children's intellectual development.
