Objective:
To determine whether emotional stability distinguishes how experienced and novice meditators react to visual stimuli.
Design:
PARTICIPANTS practiced concentrative meditation and then responded to visual stimuli while continuing to meditate.
Participants:
Ten experienced and 10 novice meditators responded to sequences of visual stimuli after concentrative meditation.
Results:
As predicted, both groups had increased parasympathetic activities during concentrative meditation. Experienced meditators had increased low-frequency electroencephalography (EEG) rhythms in response to visual stimulation, whereas novices had increased high-frequency EEG rhythms. Correlational analyses revealed that novice meditators changed from a meditative state to a nonrelaxed state when the visual stimuli were presented, whereas experienced meditators maintained the meditative state.
Conclusion:
The study provides evidence that regular concentrative meditation can improve emotional stability and that recording physiologic responses to visual stimuli can be a good method for identifying the effects of long-term concentrative meditation practice.

The Role of Exercise in Stress Management
Regular physical activity is essential for reducing stress and promoting cardiovascular health. Exercise strengthens the heart, enhances blood flow, keeps blood vessels flexible, and helps lower blood pressure, all of which reduce the body's stress response. Research shows that adults who exercise regularly have nearly half the...
