Long-established rituals in preexisting cultural groups have been linked to the cultural evolution of group cooperation. We tested the prediction that novel rituals-arbitrary hand and body gestures enacted in a stereotypical and repeated fashion-can inculcate intergroup bias in newly formed groups. In four experiments, participants practiced novel rituals at home for 1 week (Experiments 1, 2, a...

Three experiments explored the impact of mourning rituals after losses – of loved ones, lovers, and lotteries – on mitigating grief. Participants who were directed to reflect on past rituals or who were assigned to complete novel rituals after experiencing losses reported lower levels of grief. Increased feelings of control after rituals mediated the link between use of rituals and reduced grie...

Previous research by Rachman and de Silva (1978, Behaviour Research and Therapy, 16, 233-248) and by Salkovskis and Harrison (1984, Behaviour Research and Therapy, 22, 549-552) has shown that abnormal and normal obsessions are similar in content. The present study examined whether the same is true for abnormal and normal rituals. A sample of normal subjects (N = 150) were asked about their idio...

This study proposes that performative rituals-that is, verbal and physical acts that reiterate prior uses-enabled medieval women and men to negotiate the dangers and difficulties of conception and childbirth. It analyzes the rituals implicated in charms, prayers, amulets, and prayer rolls and traces the circulation of such rituals within medieval English society. Manuscript records from the Ang...

Religion and ritual have been characterized as costly ways for conditional cooperators to signal their type, and thus identify and interact with one another. But an effective signal may be prohibitively expensive: if the cost of participation is too small, freeriders may send the signal and behave selfishly later. However, if the ritual reveals only the average level of signaling in a group, fr...

OBJECTIVE Family rituals are associated with adaptive functioning in pediatric illness, including quality of life (QoL). This article explores the role of family cohesion and hope as mediators of this association in children with cancer and their parents. METHODS Portuguese children with cancer (N = 389), on- and off-treatment, and one of their parents completed self-report measures. Structur...
