Mindfulness, cognition, and long-term meditators: Toward a science of advanced meditation

Mindfulness meditation is a form of mental training rooted in ancient wisdom traditions and is focused on cultivating a non-judgmental stance toward present-moment awareness. Here, we synthesize cognitive-behavioral effects in long-term meditators (LTMs) resulting from diverse and prolonged meditation practices. Preliminary evidence suggests that LTMs exhibit increased cognitive-sensory integration and decoupling of affective processes, as demonstrated in enhanced interoceptive awareness, reduced negative affective pain perception, and more rational decision-making. Additionally, LTMs may experience more emotional neutrality, self-boundary dissolution, and less normative self-awareness. Neuroimaging findings include increased bottom-up activation, particularly within the salience network (interoception, pain, affect), and reduced connectivity between the executive (dorsolateral prefrontal cortex) and salience (dorsal anterior cingulate cortex) networks (reduced pain). Research also displayed reduced amygdala activation to fear (reduced negative affect), increased temporoparietal junction activation (pre-reflective experiential processes, empathy), and altered midline default-mode network activation, which is associated with emotional neutrality and pre-reflective experiential processes, such as non-ordinary states of consciousness. Methodological limitations, specifically heterogeneous predictor variables, restrict the interpretation of trait effects, temporal dynamics in cognitive processing, and the unique influences of meditative activities. These limitations indicate the need for a unified research framework and a systematic neurophenomenological investigation of advanced meditation—through the study of unfolding states, stages, and endpoints in meditative development. In summary, LTMs display a distinct neurophenomenological gestalt of mindfulness, wherein meditative expertise is reflected in altered general brain processing, potentially enhanced cognitive integration, increased cognitive flexibility and self-regulation, and heightened non-dual awareness—signifying a potentially important form of embodied cognition.
