Summary
This study established standard values for a modified Stroop test, revealing significant age-related changes in cognitive flexibility and attention. Optimal performance in this selective attention task was observed in 16-17 year olds.
Area of Science:
- Cognitive Psychology
- Neuroscience
- Developmental Psychology
Context:
- The original Stroop test, a measure of selective attention and cognitive flexibility, is challenging for children with developmental disorders due to its length.
- A modified Stroop test with reduced stimuli (72) was developed for clinical use.
Purpose:
- To establish normative data for the modified Stroop test in children and adults aged 6-20.
- To investigate developmental trajectories of the interference effect within this age range.
Summary:
- Two hundred eighty-one typically developing individuals (6-20 years) were assessed using the modified Stroop test.
- Simple regression analysis examined age-related changes in Incongruent Color Naming (ICN), ICN--Color Naming (CN), and ICN/CN indices.
- Significant age-related improvements were found, with peak performance between 16-17 years.
Impact:
- Provides normative data essential for the clinical application of the modified Stroop test.
- Suggests that late-maturing brain regions or functional systems underpin performance on interference tasks.
- Offers insights into the developmental maturation of cognitive control mechanisms.
