Scientific interest in mindfulness has grown exponentially in the past decade but, until now, it has typically been approached from a clinical perspective. This volume is the first to take a social-psychological approach to mindfulness research. It provides theoretical and methodological guidance for researchers across disciplines who are interested in the field and discusses fundamental processes in mindfulness, including its effect on emotion regulation, executive control, automatic and deliberative processing, and its relationship to self-construal and self-identity. It also considers mindfulness in the context of a series of applied domains, exploring its links with compassion and prosocial behaviour, the experience of awe in everyday life, health behavior, romantic relationship functioning, and prejudice and ingroup bias.
