Daily worry impacts cognitive processing, especially with ambiguous information. Engaging in worry increases negative thoughts, disrupting cognitive function for both worriers and non-worriers.

Area of Science:

  • Cognitive Psychology
  • Clinical Psychology
  • Neuroscience

Background:

  • Daily worry is common and may affect cognitive functions.
  • Previous research suggests a link between worry and altered cognitive processing.

Purpose of the Study:

  • To investigate if daily worry level predicts cognitive processing differences.
  • To determine if negative thoughts mediate the relationship between worry and cognitive disruption.

Main Methods:

  • Study 1: Compared cognitive categorization task performance between high-worry individuals and non-worriers under varying ambiguity levels.
  • Study 2: Examined the effect of induced worry (15-minute worry period) versus a relaxed state (mind-wandering) on cognitive processing in both worriers and non-worriers.

Main Results:

  • Worriers showed impaired performance on ambiguous categorization tasks compared to non-worriers.
  • Induced worry disrupted cognitive processing in non-worriers to a similar extent as observed in high-worriers.
  • Reducing worry (O-worry condition) lessened cognitive disruption in worriers.

Conclusions:

  • Daily worry level is a significant predictor of cognitive processing differences.
  • Negative thoughts associated with worry are the mechanism driving these cognitive disruptions.
  • Cognitive processing changes linked to worry are observable in both habitual worriers and non-worriers under induced worry conditions.
