Insights
This study examined the Stroop paradigm in Brazilian children aged 7-10. Younger children were slower and more susceptible to interference, indicating developmental changes in processing speed and attention.
Area of Science:
- Neuroscience
- Developmental Psychology
Background:
- The Stroop paradigm assesses interference susceptibility, linked to frontal lobe function.
- Stroop performance evolves developmentally.
- Limited research exists on the Stroop paradigm within Brazilian populations.
Purpose of the Study:
- Investigate Stroop paradigm performance in Brazilian children.
- Analyze the effect of age on Stroop performance in this demographic.
Main Methods:
- Utilized the Victoria version of the Stroop test.
- Sample comprised 119 children aged 7 to 10 years.
Main Results:
- Brazilian children's Stroop performance mirrored international findings.
- Younger children (7-10 years) exhibited slower naming times and increased susceptibility to interference compared to older children.
- A positive correlation was found between age and naming time; a negative correlation between age and errors in maximal interference.
Conclusions:
- Age significantly impacts Stroop performance in children.
- Developmental changes in information processing speed and attention selectivity explain the observed age effects.
Background:
The Stroop paradigm evaluates susceptibility to interference and is sensitive to dysfunction in frontal lobes. Performance in the Stroop changes along the development. Despite its usefulness in research and clinical settings, there are few studies with Brazilian samples.
Objective:
This study investigates the performance and age effect on Stroop paradigm of Brazilian children.
Method:
A sample of 119 children, aged from 7 to 10 years, was submitted to the Victoria version of Stroop.
Results:
The pattern of results observed was similar to that observed in foreign studies with adults and children. Younger children were overall slower than older ones (positive correlation between age and naming time). Also, younger children showed more susceptible to interference than older ones (negative correlation between age and number of errors for the maximal interference condition).
Conclusion:
There was an age effect explained in terms of developmental changes in information processing velocity and attention selectivity.
