Separating twins in the classroom can lead to more internalizing problems and lower reading scores, particularly for identical twins. Early separation shows more significant behavioral issues.

Area of Science:

  • Developmental Psychology
  • Educational Psychology
  • Twin Studies

Background:

  • Classroom placement for twins is a common parental and educational decision.
  • Previous research on twin separation in schools is limited.
  • Understanding the impact on twins' development is crucial for educational practices.

Purpose of the Study:

  • To investigate the effects of classroom separation on twins' behavior, academic progress, and reading abilities.
  • To compare outcomes for twins separated at different stages.
  • To examine differences between monozygotic and dizygotic twins regarding separation effects.

Main Methods:

  • Longitudinal study (E-risk Study) of a nationally-representative twin sample.
  • Assessment at ages 5 and 7.

  • Comparison of three groups: always together, always separated, separated between ages 5 and 7.
  • Main Results:

    • Twins separated by age 7 showed more internalizing problems and lower reading scores compared to non-separated twins.
    • Early separation (by age 7) was associated with significantly more internalizing problems.
    • Identical (monozygotic) twins exhibited more negative effects from separation than fraternal (dizygotic) twins.

    Conclusions:

    • Classroom separation can negatively impact twins' emotional well-being and academic performance.
    • The timing and type of twin pair (MZ vs. DZ) influence the effects of separation.
    • Findings inform school policies and support strategies for twins and their families.
