Conscious intrusion of threat information via unconscious priming in anxiety

Preferential processing of threat has been implicated in the development and perpetuation of anxiety. We investigated threat processing and anxiety using a subliminal priming paradigm. People with high or low trait anxiety viewed masked, briefly presented words, and then took an exclusion-completion test in which threeletter stems were to be completed without using recently perceived words. Completion rates were greater for words viewed subliminally compared to a baseline estimate. In addition, unconscious priming was greater for threat than for neutral words in the high-trait-anxiety group, and for neutral than for threat words in the low-trait-anxiety group. Enhanced unconscious priming of threat completions among anxious individuals may model intrusions in anxiety, when unconscious processing breaks into consciousness in the form of threat-related intrusive thoughts.
