Studies investigating the relationship between Turner syndrome and math
learning disability have used a wide variation of tasks designed to test various
aspects of mathematical competencies. Although these studies have revealed much
about the math deficits common to Turner syndrome, their diversity makes
comparisons between individual studies difficult. As a result, the consistency of
outcomes among these diverse measures remains unknown.
The overarching aim of
this review is to provide a systematic meta-analysis of the differences in math
and number performance between females with Turner syndrome and age-matched
neurotypical peers. METHOD: We provide a meta-analysis of behavioral performance
in Turner syndrome relative to age-matched neurotypical populations on
assessments of math and number aptitude. In total, 112 comparisons collected
across 17 studies were included. RESULTS: Although 54% of all statistical
comparisons in our analyses failed to reject the null hypothesis, our results
indicate that meaningful group differences exist on all comparisons except those
that do not require explicit calculation. INTERPRETATION: Taken together, these
results help elucidate our current understanding of math and number weaknesses in
Turner syndrome, while highlighting specific topics that require further
investigation.
