Insights

This study examined Wisconsin Card Sorting Test (WCST) performance in Turkish children aged 8-11. Results show cognitive skills improve with age, particularly reducing perseverative errors around age 10.

Area of Science:

  • Developmental psychology
  • Neuropsychology
  • Cognitive science

Background:

  • Executive functions are crucial for cognitive development.
  • The Wisconsin Card Sorting Test (WCST) is a key tool for assessing executive functions.
  • Understanding developmental trajectories of executive functions in diverse populations is important.

Purpose of the Study:

  • To investigate age-related changes in executive functions using a computerized WCST in Turkish children.
  • To identify specific developmental trends in WCST performance components.
  • To explore the influence of parental education on children's WCST performance.

Main Methods:

  • A computerized version of the Wisconsin Card Sorting Test was administered.
  • 449 Turkish children aged 8 to 11 years participated.
  • Statistical analyses examined age and parental education effects.

Main Results:

  • WCST performance significantly improved with age in children.
  • Distinct developmental patterns were observed across different WCST components.
  • A notable decrease in perseverative errors occurred around age 10.
  • Maternal education level was the strongest predictor of WCST performance.

Conclusions:

  • Executive functions, as measured by the WCST, show significant development during middle childhood.
  • Perseverative tendencies are particularly sensitive to developmental changes around age 10.
  • Maternal education plays a significant role in supporting children's cognitive development and executive function performance.
