Intensive meditation training reduces the attentional blink—a phenomenon where a second target in a rapid stream is often missed when it appears shortly after a first target. Three months of daily mental practice led to a smaller attentional blink and decreased brain-resource allocation to the first target, measured by a smaller P3b brain potential. Individuals with the largest reduction in resource allocation to the first target showed the greatest improvement in detecting the second target. These findings indicate that mental training enhances control over limited attentional resources and supports lifelong brain plasticity.
Three months of intensive meditation training improved the ability to sustain attention, as measured by dichotic listening task performance and electroencephalography. Training reduced variability in attentional processing of target tones, shown by enhanced theta-band phase consistency of neural responses over anterior brain areas and reduced reaction time variability. Individuals with the greatest increase in neural response consistency showed the largest decrease in behavioral response variability. Reduced variability in neural processing also occurred for unattended deviant tones, suggesting meditation affects both distracter and target processing, possibly by enhancing entrainment of neuronal oscillations to sensory input rhythms.
Non-dual meditation, which aims to reduce maladaptive patterns by recognizing their transient nature, can downregulate automatic perceptual habits. EEG recordings from expert Buddhist practitioners and novices during Open Presence (OP) and Focused Attention (FA) meditation, plus a control state, showed increased gamma oscillatory power during both meditation states in experts. An interaction between states and groups emerged in the Mismatch Negativity (MMN) amplitude, with the MMN increasing during FA compared to OP in experts, while the opposite pattern occurred at the Late Frontal Negativity (LFN) latency. This suggests OP involves increased sensory monitoring and reduced perceptual inferences relative to FA.
