Visual but not spatial working memory deficit in children with spina bifida

Area of Science:

• Neuroscience
• Developmental Psychology
• Cognitive Science

Background:

• Spina bifida is a complex congenital condition affecting neural development.
• Understanding cognitive profiles in spina bifida is crucial for targeted interventions.
• Visuospatial working memory is a key cognitive function often impacted by neurological conditions.

Purpose of the Study:

• To investigate visuospatial working memory abilities in children with spina bifida.
• To compare performance between children with spina bifida and typically developing controls.
• To explore the specific components of visuospatial working memory affected by spina bifida.

Main Methods:

• Assessment of 20 children with spina bifida and 20 controls.
• Utilized a battery of visuospatial working memory tests.
• Included forward and backward Corsi tests and a novel 'House Visual Span' test.

Main Results:

• Children with spina bifida performed comparably to controls on general visuospatial and Corsi tests.
• Significant impairment was observed in the 'House Visual Span' test for the spina bifida group.
• The 'House Visual Span' test assesses discrimination between visual targets and lures, requiring specific visual processing.

Conclusions:

• Results support a distinction between visual and spatial components within working memory.
• Children with spina bifida may have specific deficits in visual processing rather than general visuospatial working memory capacity.
• Findings contribute to refining working memory models and understanding cognitive sequelae of spina bifida.
