Developmental psychologist says more standardised diagnostic criteria are needed, general cognitive impairments have to be taken into account
Preterm children do not suffer from dyscalculia more often than healthy full term children.
Dr Julia Jäkel, a developmental psychologist from Bochum, and her colleague Prof Dr Dieter Wolke from the University of Warwick, UK proved this thesis to be true in their analyses - thus refuting previous scientific studies.
Unlike other studies, the researchers took the children's IQ into consideration.
Dyscalculia in preterm children often impossible to diagnose
Preterm children often have cognitive deficits; they find solving complex tasks particularly difficult. However, dyscalculia is as rare in those children as in their healthy term born peers.
In order to assess specific mathematics deficiencies, children in Germany undergo a number of tests. If their result falls below a specific cut off value in maths, whilst their general cognitive skills (IQ) are normal, the diagnosis is "maths learning disorder" or "dyscalculia". But because preterm children frequently have general cognitive problems, they are impossible to be diagnosed with current criteria; consequently, they do not receive the required tuition in maths.
Julia Jäkel thus argues for internationally standardised criteria which would allow diagnosing dyscalculia in children with mild cognitive impairments.
