NEW MODEL OF IQ DEVELOPMENT ACCOUNTS FOR WAYS THAT EVEN SMALL ENVIRONMENTAL CHANGES CAN HAVE A BIG IMPACT, WHILE STILL CREDITING THE INFLUENCE OF GENES
Implications for Enrichment Programs for School-Aged Children
WASHINGTON - A new mathematical model could help explain how certain environments can trigger changes in a person's IQ as well as the relative influence of genes and the environment on IQ by exploring how internal and external factors might interact. The model helps explain the puzzling finding that IQ scores have risen over time and suggests a larger environmental role in IQ than previously thought. The model and an extensive discussion appear in the April issue of Psychological Review, published by the American Psychological Association (APA).
