In this study, typically developing students were tested for their IQ and working memory at 5 years old and again when they were 11 years old. They were also tested on their academic attainments in reading, spelling and maths.

Findings and Educational Implications

The findings revealed that a child’s success in all aspects of learning is down to how good their working memory is regardless of IQ score. Critically, working memory at the start of formal education is a more powerful predictor of subsequent academic success than IQ in the early years.

This unique finding is important as it addresses Read the rest of this entry »
