Attentional Control and Suppressing Negative Thought Intrusions in Pathological Worry

Area of Science:

• Cognitive Psychology
• Neuroscience
• Clinical Psychology

Background:

• Adaptive behavior requires efficient filtering of irrelevant information, a key aspect of attentional control.
• Difficulties in ignoring irrelevant stimuli are linked to dispositional differences in worry.
• High worriers exhibit core deficits in attentional control.

Purpose of the Study:

• To investigate the relationship between trait worry and attentional control deficits.
• To examine the correlation between attentional control deficits and the suppression of negative thought intrusions.
• To assess the efficacy of cognitive training in improving attentional control and reducing worry intrusions.

Main Methods:

• Two studies were conducted involving participants assessed for trait worry and attentional control.
• A flanker task was employed as a cognitive training intervention to enhance attentional control.
• Worry assessment tasks were used to measure the suppression of negative thought intrusions.

Main Results:

• Fundamental difficulties in ignoring irrelevant material were associated with trait propensity to worry.
• Deficits in attentional control correlated with challenges in suppressing negative thought intrusions.
• Cognitive training showed limited effectiveness, but improvements in attentional control correlated with better suppression of worry intrusions.

Conclusions:

• The inability to control worry-related thought intrusions is linked to a general deficiency in attentional control.
• Trait worry is associated with fundamental deficits in ignoring irrelevant information.
• Findings suggest a core attentional control deficit underlies difficulties in managing worry.
