The factor structure of the Lateral Preference Schedule (LPS) differs in preadolescents compared to adults. The original six-factor solution was not replicated, highlighting the need for caution when using the LPS with younger individuals.

Area of Science:

  • Psychology
  • Developmental Psychology
  • Psychometrics

Background:

  • The Lateral Preference Schedule (LPS) is a tool used to assess laterality.
  • Previous research established a six-factor structure for the LPS in adult samples.

Purpose of the Study:

  • To investigate the stability of the Lateral Preference Schedule's (LPS) factor structure in preadolescents.
  • To determine if the factor structure observed in adults is maintained in a younger population.

Main Methods:

  • A sample of 568 preadolescents was analyzed.
  • Factor analysis was employed to examine the LPS factor structure.
  • The results were compared to the original adult standardization sample.

Main Results:

Related Experiment Videos

  • The factor analysis of the preadolescent sample yielded four factors, not the six reported for adults.
  • The original six-factor structure of the LPS was not maintained in this preadolescent cohort.

Conclusions:

  • The factor structure of the Lateral Preference Schedule (LPS) is not stable across age groups.
  • Caution is advised when applying the six-factor solution of the LPS to preadolescent samples.
  • Further research may be needed to validate the LPS for use in pediatric populations.
