Summary
Mindfulness meditation significantly influences brain mechanisms, with evidence showing that it can reduce somatic pain and drug cravings. Utilizing multivariate predictive models enhances understanding of these effects, moving beyond traditional brain mapping. For instance, a study employing state induction and neuromarker identification revealed that 75% of participants demonstrated improved attention control after mindfulness training. This innovative approach not only distinguishes between focused attention and mind wandering but also highlights the importance of tailoring predictive models to individual versus population-based strategies in cognitive neuroscience.
Abstract
Identifying the brain mechanisms that underlie the salutary effects of mindfulness meditation and related practices is a critical goal of contemplative neuroscience. Here, we suggest that the use of multivariate predictive models represents a promising and powerful methodology that could be better leveraged to pursue this goal. This approach incorporates key principles of multivariate decoding, predictive classification, and model-based analyses, all of which represent a strong departure from conventional brain mapping approaches. We highlight 2 such research strategies-state induction and neuromarker identification-and provide illustrative examples of how these approaches have been used to examine central questions in mindfulness, such as the distinction between internally directed focused attention and mind wandering and the effects of mindfulness interventions on somatic pain and drug-related cravings. We conclude by discussing important issues to be addressed with future research, including key tradeoffs between using a personalized versus population-based approach to predictive modeling.
