Modern food environments interact with human biology to promote reward-related eating through associative learning, specifically operant conditioning. Standard weight-loss diets that rely on dietary restriction have shown little long-term benefit and may be counterproductive because they do not directly target the habit-based reward-related eating cultivated by positive and negative reinforcement. Mindfulness training that targets reward-based learning may help rewire the eating process. Teaching patients to act on intrinsic rewards—such as enjoying healthy eating, not overeating, and self-compassion—rather than extrinsic rewards like weighing oneself, offers a promising new direction for improving individuals' relationship with food.

Meditation practices, which have shown therapeutic benefits for conditions like depression, pain, addiction, and anxiety, have been studied with neuroimaging over the past decade. However, existing neuroscientific models are based on small, heterogeneous datasets, limiting generalizability and replicability. The ENIGMA-Meditation consortium is the first worldwide collaborative effort to conduct systematic meta- and mega-analyses of globally distributed neuroimaging data using standardized methods. This framework aims to improve statistical power and address multidomain heterogeneity in meditation practice types, experience, and experimental design. The consortium will generate rigorous neuroscientific insights into the mechanisms underlying meditation's therapeutic effects on psychological and cognitive attributes.

The observer effect—the idea that observing a phenomenon changes it—is often seen as a problem to control, but this paper argues it should be actively studied and used. Mindfulness practices, which cultivate present-moment, nonjudgmental awareness, are proposed as a way to account for and intentionally harness this effect. In research, mindfulness training may help participants give more precise self-reports by reducing reactive biases. Evidence suggests mindfulness improves interoceptive awareness and reduces automatic judgment, potentially increasing measurement validity. Clinically, therapies often aim to make unconscious patterns observable; mindfulness cultivates meta-awareness, allowing individuals to observe cravings or anxiety without reactivity, facilitating psychological change. The paper proposes developing an observer-effect index to code observer influence.
