Negative affectivity, effortful control, and attention to threat-relevant stimuli

Area of Science:

• Psychology
• Developmental Psychology
• Clinical Psychology

Background:

• Temperament significantly influences psychopathology risk.
• Negative affectivity (NA) is linked to anxiety and depression, but underlying mechanisms require further investigation.
• Interactions between reactive temperament, effortful control (EC), and cognitive factors like attentional bias are potential mechanisms.

Purpose of the Study:

• To investigate the relationship between high NA, low EC, and attentional bias toward threat in children.
• To test if EC moderates the association between NA and attentional bias.

Main Methods:

• A sample of 104 children (4th-12th graders) with high or low trait NA and EC was selected.
• Participants completed a dot probe detection task to assess attentional bias to threat stimuli.

Main Results:

• Effortful control (EC) moderated the link between negative affectivity (NA) and attentional bias.
• An attentional bias toward threat was observed exclusively in children with high NA and low EC.
• This pattern was consistent across different grade levels and ages.

Conclusions:

• Low effortful control (EC) exacerbates the effect of high negative affectivity (NA) on attentional bias.
• Findings highlight the critical role of effortful control in modulating threat-related cognitive biases in children.
• Understanding these temperament-emotion-cognition interactions is crucial for psychopathology risk assessment.
