On the relationship between mathematics and visuospatial processing in Turner syndrome

Area of Science:

• Neuroscience
• Developmental Psychology
• Genetics

Background:

• Turner syndrome (TS) commonly presents with intact overall IQ but deficits in math and visuospatial reasoning.
• Disparities exist in how visuospatial domains relate to mathematical abilities in individuals with TS.
• Longitudinal data are needed to understand the evolving relationship between visuospatial skills and math performance in TS.

Purpose of the Study:

• To longitudinally investigate visuospatial processing and its relationship to math performance in adolescent girls with TS.
• To compare these relationships in girls with TS versus age-matched healthy controls.
• To identify specific visuospatial domains that may underlie math deficits in TS.

Main Methods:

• A 4-year longitudinal study involving annual assessments of math and visuospatial tests.
• Inclusion of adolescent girls with TS and age-matched healthy controls.
• Application of linear mixed effects modeling to analyze the time-dependent relationships.

Main Results:

• Math performance was significantly associated with visual tracking, visual-motor coordination, and figure-ground processing in girls with TS.
• These specific visuospatial domains appear uniquely affected by TS.
• Performance differences in math and visuospatial tests between girls with TS and controls remained stable throughout the study period.

Conclusions:

• Specific visuospatial deficits, including visual tracking, visual-motor coordination, and figure-ground processing, are linked to math performance in Turner syndrome.
• These findings highlight the critical role of visuospatial skills in early math development for individuals with TS.
• The stable nature of these deficits suggests a need for targeted interventions to improve math education in children with TS.
