#295 Metacognition, Cognitive Defusion, Executive Control

     We're all on autopilot most of the time, caught up in the momentum of the story of our lives, like swimmers in a fast-moving river. This momentum includes automatic reactive thought patterns and persistent moods, and provide the illusion of stability and control. Momentum seems strong, most of it causes suffering, and is entirely optional.
     "A clue as to how a standardized form of mindfulness meditation practice (ST-Mindfulness) affects mood and distress comes from findings that it leads to beneficial changes in cognitive processing in people with mood disorders, chronic functional disorders and chronic pain. Thus, ST-Mindfulness is reported to reduce self-reported rumination, which is the negative repetitive, self-related internal cognitions that predominate in major depression. In chronic pain and functional disorders, ST-Mindfulness is reported to reduce patients’ tendency to catastrophize and engage in repetitive negative cognitions such as, the pain is 'terrible and I feel it’s never going to get better'.
     Based on these self-reports of decreased rumination and related findings, numerous reviews have converged on metacognition - insight into one’s own thinking process, sometimes described as 'decentering' or 'reperceiving' - as a grand-mechanism underlying ST-Mindfulness efficacy. According to this view, metacognition is an emergent property of mindfulness practice in ST-Mindfulness that is derived from training in subsidiary mechanistic processes including attention and emotion regulation. Drawing on this emergent metacognitive capacity, ST-Mindfulness practitioners learn to monitor their moment-by-moment experience so that they can 'step back' from negative, distressing thoughts and feelings in order to view them as 'mental events' rather than as unmediated reflections of reality."
