Plasticity in attention: implications for stress response in children

Area of Science:

• Psychology
• Child Psychiatry
• Cognitive Neuroscience

Background:

• Attention bias is a proposed factor in anxiety development and maintenance.
• Empirical evidence for a causal link between attention bias and anxiety is limited, particularly in children.

Purpose of the Study:

• To investigate if inducing an attentional bias can alter stress vulnerability in children.
• To examine the causal relationship between attentional bias and anxiety in a pediatric population.

Main Methods:

• Twenty-six children (7-12 years) were randomly assigned to either threat-avoidance or threat-attention training.
• Participants underwent stress induction post-training.
• Changes in attentional bias, depression, and anxiety were measured.

Main Results:

• Threat-attention training successfully induced attentional vigilance to threat.
• Threat-avoidance training was ineffective in altering attentional bias.
• Both groups showed increased depression post-stress; only the threat-attention group reported increased anxiety.

Conclusions:

• Biased attentional responses to threat can specifically influence anxiety development in children under stress.
• This study provides preliminary evidence for a causal role of attention bias in childhood anxiety.
