Insights

Extremely low birth weight (ELBW) children showed poorer visuospatial skills than term peers at age 6. The Test of Visuospatial Construction (TVSC) effectively identifies these differences, aiding early intervention for preterm children.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Pediatrics

Background:

  • Visuospatial skills are crucial for cognitive development.
  • Preterm birth, particularly extremely low birth weight (ELBW), is associated with increased risk of neurodevelopmental challenges.
  • Assessing visuospatial abilities in young children requires validated, motor-independent measures.

Purpose of the Study:

  • To evaluate the validity of the Test of Visuospatial Construction (TVSC) in assessing visuospatial skills in preschool and kindergarten-aged children.
  • To compare visuospatial performance between extremely low birth weight (ELBW), late preterm (LPT), and term-born children.
  • To determine if the TVSC can detect differences in visuospatial construction abilities related to birth weight status and track developmental changes.

Main Methods:

  • The Test of Visuospatial Construction (TVSC) was administered to 355 preschoolers and 265 kindergartners.
  • Participants included extremely low birth weight (ELBW), late preterm (LPT), and term-born children.
  • Statistical analyses included correlations with other cognitive tests and one-way ANOVAs to compare group performance at ages 3 and 6.

Main Results:

  • The TVSC demonstrated weak-to-moderate correlations with established measures of cognitive and visuospatial abilities.
  • At age 3, ELBW children performed significantly worse than term children on the TVSC (p=.044, d=-0.43).
  • By age 6, both ELBW and LPT children performed significantly worse than term children, with larger effect sizes observed compared to age 3. Differences between LPT and term children present at age 3 diminished by age 6.

Conclusions:

  • The TVSC shows preliminary validity as a measure of visuospatial construction in young children.
  • The TVSC can identify neurodevelopmental impairments in visuospatial skills among preterm-born children.
  • Findings support the use of the TVSC for early detection and intervention planning in at-risk populations.
