Neurocognitive Correlates of Rumination Risk in Children: Comparing Competing Model Predictions in a Clinically...

Area of Science:

• Psychology
• Neuroscience
• Developmental Psychology

Background:

• Rumination is a cognitive pattern associated with negative affect and psychopathology.
• Existing models of rumination primarily focus on adults, with limited research on youth.
• Executive functions, including working memory updating, inhibition, and shifting, are crucial for cognitive control.

Purpose of the Study:

• To extend conceptual models of rumination to preadolescent youth.
• To clarify how working memory updating, inhibition, and shifting relate to rumination in children.
• To investigate differential neurocognitive predictions for sadness and anger rumination.

Main Methods:

• A sample of 159 preadolescent youth (aged 8-13), oversampled for ADHD and psychopathology, completed self-report rumination measures.
• Participants underwent computerized neurocognitive tasks assessing executive functions: working memory updating, inhibition, and shifting.
• Multiple regression analyses were used to examine unique associations between sadness and anger rumination and executive functions, controlling for each other.

Main Results:

• Sadness rumination was significantly associated with poorer working memory updating (β = -0.18, p = 0.046) and shifting abilities (β = 0.20, p = 0.03).
• Anger rumination was associated with better working memory updating (β = 0.20, p = 0.03) but not inhibition or shifting.
• No significant associations were found between sadness rumination and inhibition, or anger rumination and inhibition or shifting.

Conclusions:

• The findings suggest developmental differences in the neurocognitive correlates of rumination in youth compared to adults.
• Executive function correlates of responding to negative emotions in children are affect-specific.
• Sadness rumination is linked to difficulties in cognitive flexibility and updating, while anger rumination may involve enhanced maintenance of negative thoughts.
