The neuroscience of empathy has relied on a simplified affective/cognitive dichotomy that cannot explain recent data from naturalistic and intergroup studies. Drawing on phenomenological philosophy, a new neuro-phenomenological account breaks through this dichotomy, emphasizing empathy as dynamic, subjective, and piecemeal. The graded empathy hypothesis postulates that attending to others' expressions always facilitates empathy, but the level of empathic experience varies parametrically with one's social interest in the observed other, such as through intergroup or interpersonal cues. This framework integrates neuroscience with phenomenology to offer a more accurate perspective for real-life experimentation.
Meditators from three traditions (Vipassana, Himalayan Yoga, Isha Shoonya) show higher gamma brainwave amplitude in the parieto-occipital region (60-110 Hz) compared to non-meditators, both during meditation and during instructed mind-wandering. This gamma activity increases with more meditation experience and is not due to eye or muscle artifacts. Vipassana practitioners also show higher alpha activity (7-11 Hz) than all other groups, while Himalayan Yoga practitioners show lower alpha activity (10-11 Hz) specifically during meditation. The findings indicate that meditation practice is associated with changes in gamma frequency EEG activity common across different meditation styles.
