描述（由申请人提供）：本项目将研究两种不同形式的冥想训练对情绪调节方面的影响。一种形式的冥想是专门设计来激发和提高同情和爱心的品质。另一种形式的冥想正念冥想据说可以改变一个人与他/她的情绪的关系，这样这个人就不那么认同他们，他们也不太可能坚持下去。这个项目的一个主要目标是调查这些形式的心理训练对情绪反应和调节的影响。这一目标将通过两个主要样本的调查来实现：1。接受为期8周的正念减压（MBSR）标准化计划的个人，其中包括慈爱和同情的训练;专家冥想者，每天至少冥想30分钟，持续10年，包括慈爱/同情和正念冥想。在后一组参与者中，我们将在三种情况下进行评估：在没有冥想的情况下进行初始测试;在10小时的同情/慈爱冥想练习后进行密集的一天;在10小时的正念冥想练习后进行密集的一天。对正念减压疗法组的评估将是纵向的，因为我们可以在培训之前和之后获得评估。MBSR组还将包括4个月的随访期。我们还将使用一个高度结构化的，非常匹配的对照组作为MBSR组，我们称之为健康增强计划（HEP），该计划在接触时间，日常实践，班级结构等方面进行匹配，但这并不包括正念或慈爱/同情的成分。这些样本中的每一个参与者都将在为期两天的实验室中进行测试，以评估慈爱/同情冥想和正念冥想对描绘人类痛苦的情感图片的反应和恢复的影响。将使用惊吓和面部肌电图测量外周生理反应性和恢复，并使用功能性磁共振成像（fMRI）评估与反应性和恢复相关的神经回路。我们还将研究这些不同形式的冥想对皮质醇对特里尔社会压力任务（TSST）的反应的影响，并研究冥想练习产生的大脑变化与TSST反应变化之间的关系。最后，还将评估在本项目和项目2和3中获得的措施之间的关系。

DESCRIPTION (provided by applicant): This project will examine the impact of two different forms of meditation training on aspects of emotion regulation. One form of meditation is specifically designed to prime and enhance qualities of compassion and loving kindness. Another form of meditation-mindfulness meditation-is said to alter an individual's relationship with his/her emotions so that the individual is less identified with them and they are less likely to perseverate. A major goal of this project is to investigate the impact of these forms of mental training on emotional reactivity and regulation. This goal will be realized by the investigation of two primary samples: 1. Individuals undergoing a standardized program of 8 weeks of mindfulness-based stress reduction (MBSR) that includes training in loving-kindness and compassion; and 2. individuals who are expert meditators with daily meditation practices of at least 30 minutes/day for 10 years that include both lovingkindness/ compassion and mindfulness meditation. Among this latter group of participants, we will conduct assessments on three occasions: an initial testing session without preceding meditation; after an intensive day of 10 hours of practice of compassion/loving-kindness meditation; and after an intensive day of 10 hours of practice of mindfulness meditation. Assessment of the MBSR group will be longitudinal since we can obtain assessments before and after the training is presented. A four-month follow-up period will also be included for the MBSR group. We will also use a highly structured, very well-matched comparison group for the MBSR group, one that we have termed the Health Enhancement Program (HEP) that is matched on hours of contact, daily practice, class structure etc., but that does not include a mindfulness or lovingkindness/compassion component. Participants from each of these samples will be tested in laboratorysessions conducted over the course of two days to assess the impact of loving-kindness/compassion meditation and mindfulness meditation on reactivity to and recovery from emotional pictures that depict human suffering. Peripheral physiological reactivity and recovery will be measured with startle and facial electromyography and the neural circuitry associated with reactivity and recovery will be assessed with functional magnetic resonance imaging (fMRI). We will also investigate the impact of these different forms of meditation on cortisol reactivity to the Trier Social Stress Task (TSST) and examine relations between changes in the brain produced by the meditation practices and changes in response to the TSST. Finally, relations between measures obtained in this project and in Projects 2 and 3 will also be assessed.
