[Results of visual perception tests in prematurely born children of pre-school age (author's transl)]
Insights
Prematurely born children, especially those small for gestational age, show significant visual-perceptual deficits compared to full-term peers. Birth weight and oxygen levels did not correlate with these visual-perceptual challenges.
Area of Science:
- Developmental Psychology
- Pediatric Neurology
- Visual Perception Studies
Context:
- Premature birth presents risks for neurodevelopmental outcomes.
- Visual-perceptual skills are crucial for preschool development and academic success.
- Previous research indicates potential long-term effects of prematurity on cognitive functions.
Purpose:
- To assess visual-perceptual abilities in preschool-aged children born prematurely.
- To compare visual-perceptual skills between premature and full-term infants.
- To investigate the relationship between prematurity factors (birth weight, small for date status, oxygen use) and visual-perceptual development.
Summary:
- Thirty-two prematurely born preschool children were evaluated using the FROSTIG developmental tests of visual perception.
- No significant differences were found between different premature groups, nor a correlation between postnatal oxygen and visual abilities.
- Significant differences in visual-perceptual abilities were observed when comparing premature children to full-term controls, with notable deficits in "small for date" infants.
Impact:
- Highlights significant visual-perceptual deficits in prematurely born children, particularly those small for gestational age.
- Suggests the need for targeted early interventions for visual-perceptual development in at-risk premature populations.
- Informs therapeutic strategies for improving developmental outcomes in children affected by prematurity.
Abstract:
Taking into account the criterions "birth weight", "small for date" (birth weight in relation to gestational age), "perinatal complications", "normal delivery" and "oxygen post partum" 32 children of pre-school age, who had been prematurely born tested with the following variables of the FROSTIG developmental tests of visual perception: visuo-motor coordination, figure-ground discrimination, perceptual constancy, space perception and perception of spacial relations. There were not significant differences between the premature-groups. No relations could be found between the quantity of O2 post partum and the tested abilities. After comparing the test subjects and a group of full-term born controls significant differences could be established. The different abilities were not related to the birth weight. Extensive deficits were observed in the "small for date" born prematures. The results are discussed with regard to their therapeutic relevance.
