Abstract
Imagination-based loving-kindness meditation (ibLKM), a new method that combines blessing and imagination developed from the scriptures of Zhiyi, has recently been proposed. The current study aims to examine one of the possible effects of this method through an empirical research approach: the enhancement of responses to pain. In the present study, 59 participants in three groups practiced ibLKM, focused attention meditation (FAM), and watched an unrelated video, respectively. Electroencephalography (EEG) data were recorded from participants who were presented with painful and non-painful pictures before and after meditation practices. Participants were asked to judge whether the stimulus was a painful picture or a non-painful picture. Event-related potential (ERP) analyses revealed that the LPP amplitudes over the central-parietal area elicited by the painful pictures were significantly more positive than those before the meditation practices in the ibLKM and FAM groups. The P3 amplitudes over the central-parietal area were significantly more positive in the posttest than in the pretest when viewing painful pictures in the FAM group. In contrast, in the ibLKM, the P3 amplitudes were not significantly different in the pretest and posttest when viewing painful pictures. These results suggested that ibLKM and FAM temporarily enhance responses to pain in different ways.
