Key result
High cardiac interoceptive awareness is linked to greater attention interference from negative emotional stimuli.
Why the study?
Individuals with high cardiac interoceptive awareness experience emotions more intensely, and whether this emotional experience arises from biases in attention remained to be investigated.
Does high cardiac interoceptive awareness alter attention processing of emotional stimuli in an emotional Stroop task compared to regular cardiac interoceptive awareness?
Cross-Sectional
Does high cardiac interoceptive awareness alter attention processing of emotional stimuli in an emotional Stroop task compared to regular cardiac interoceptive awareness?
Individuals with high cardiac interoceptive awareness exhibit automatic vigilance and attention interference for negative emotional stimuli, which may interfere with cognitive processing.

High cardiac interoceptive awareness was associated with negative emotional interference; hypothesis-generating for attentional bias and requires prospective validation.
Previous research has shown that individuals with good perception of cardiac signals, referred to as cardiac interoceptive awareness, experience emotions more intensely. To investigate if emotional experience in high cardiac interoceptive awareness arises from biases in attention, we compared the performance of participants with high versus regular cardiac interoceptive awareness in an emotional Stroop task. Participants with high cardiac interoceptive awareness showed attention interference for negative words, whereas participants with regular cardiac interoceptive awareness showed attention facilitation for positive words. Our data provide further evidence for the emotion information process associated with cardiac interoceptive awareness. The results support the notion that better access to cardiac changes accompanying negative emotional conditions results in automatic vigilance for negative information and may interfere with cognitive processing.

Werner et al. (2014) conducted a cross-sectional in Cardiac interoceptive awareness. High cardiac interoceptive awareness vs. Regular cardiac interoceptive awareness was evaluated on Performance in an emotional Stroop task (attention interference and facilitation). High cardiac interoceptive awareness resulted in attention interference for negative words, whereas regular awareness showed facilitation for positive words in an emotional Stroop task.
