Voluntary attention cannot be sustained for long periods, leading to a decline in perceptual sensitivity called the vigilance decrement. Training involving meditation practice—about 5 hours daily for 3 months—improved sustained attention. Participants were randomly assigned to receive training first or serve as waiting-list controls. Training improved visual discrimination, linked to increases in perceptual sensitivity and vigilance during sustained visual attention. These results suggest that perceptual improvements reduce the resource demand of target discrimination, making it easier to sustain voluntary attention.

Three months of intensive meditation training in an isolated retreat setting improved sustained self-regulatory control, measured by a response inhibition task, and adaptive socioemotional functioning, a latent factor combining measures of attachment, mindfulness, empathy, personality traits, emotion regulation, depression, anxiety, and well-being. A wait-list control group showed no improvement until they underwent the same training. Gains in both self-regulation and adaptive functioning were sustained at a 5-month follow-up. Dynamic modeling indicated that improvements in self-regulation drove later changes in adaptive functioning, supporting the Buddhist claim that enhanced self-regulation is a precursor to emotional well-being.

Intensive meditation training produces replicable changes in brainwave activity. In a controlled study, participants who practiced focused attention meditation for three months showed reduced beta-band power over anterior and posterior scalp regions during meditation, compared to a wait-list group that later received identical training. Individual alpha frequency also decreased across both retreats, and the decrease was directly related to the amount of meditation practice. These longitudinal changes in brain oscillatory activity help explain how meditation may support long-term improvements in attention and cognition.
