Using spreading activation to understand repetitive negative thinking

Area of Science:

• Cognitive Psychology
• Clinical Psychology
• Neuroscience

Background:

• Repetitive negative thinking (RNT) is linked to anxiety and depression.
• Previous RNT research relied on self-report, missing underlying mechanisms.
• A negatively biased semantic network is a potential RNT maintenance factor.

Purpose of the Study:

• To investigate if RNT is maintained by a negatively biased semantic network.
• To assess state RNT using a modified free association task.
• To determine if semantic retrieval patterns reflect RNT tendencies.

Main Methods:

• Participants completed a modified free association task with valenced cue words.
• State RNT was measured by the length of consecutive negative word associations (chains).
• Trait RNT and negative affect were assessed via self-report measures.

Main Results:

• Negative response chain length positively predicted trait RNT and negative affect.
• This association was significant only for positive cue words.
• Semantic retrieval patterns, specifically negative association chains, reflect RNT.

Conclusions:

• RNT tendencies are observable in semantic retrieval processes.
• A modified free association task can assess state RNT without self-report.
• Findings suggest a link between semantic networks and the persistence of maladaptive thoughts.
