Attentional Bias Among High and Low Ruminators: Eye Tracking Study in a Non-Clinical Population

Rumination, which can be studied through its associated attentional biases, and is a part of the RDoC Negative Valence Systems constructs of Loss, has been proposed as a key transdiagnostic feature in depression. The current study uses eye tracking measurements to explore how different levels of brooding and reflection rumination interact with attentional biases in a non-clinical sample of high and low ruminators. Methodology: 123 adults were administered questionnaires of rumination, depression and participated in passive viewing task in which they watched sets of angry, happy, sad and neutral faces, while their eye movements were tracked. Findings indicate greater sustained attention toward sad and angry faces and away from happy faces among non-clinical individuals with high levels of brooding rumination, even when controlling for depression scores. The study adds further evidence that brooding rumination and attentional biases to negative stimuli are associated with one another. Behavioral parameters such as attention bias to help us to distinguish high ruminators among non-clinical sample.
