This chapter reviews various ethnographic and psychological studies of dreaming and hypothesizes about the relationship between institutionalized forms of trance and the use of dreams. Results show that societies with institutionalized forms of trance are more likely to use dreams to seek and control supernatural powers.

This book investigates possession and possession-trance. While the author focuses on a case study of Haiti, there are also a handful of cross cultural tests performed. Results suggest that societal complexity is associated with belief in possession-trance, rather than possession alone.

This chapter examines the presence of oaths and autonomic ordeals in relation to various socioeconomic variables. Several hypotheses are presented, all are supported.

This study examines correlates of trance and possession in pre-industrial societies. Results suggest that the presence of trance/possession is associated with subsistence, number of jurisdictional levels, and community decision-making.

The main premise of the present study is to investigate the relationship between monotheism and dependence nurturance during early childhood and adulthood. Terry notes the human need to explain and understand the world, and theorizes that this understanding derives from personal experience, learned information, and supernatural explanation. Terry tests the hypothesis that supernatural explanations (monothestic beliefs) will be formulated if individuals cannot depend on their own experiences and/or others to reduce uncertainty (a result of independence training).

The complex set of beliefs and practices in which the cult of the guardian spirit consisted is examined.

The expressed purpose of the present publication is to provide a typology of institutionalized dissociational states on a world-wide basis, using biological, situational, and cultural parameters. The study is comprised of field work, literature review, ethnographic research, and cross-cultural statistical analysis. The researchers use these findings to aid in the construction of cross-cultural theory, and to provide a platform for further work on dissociational states to continue.

This study examines correlates of possession trance among cultures in sub-Saharan Africa. Several variables were tested (including community organization, marriage form, family form, and settlement pattern) but only a few were related to possession trance. Results indicate that the presence of slavery, stratification, and role and structure differentiation are significantly associated with possession trance.

This article offers a detailed analysis of neurophysiological processes involved in altered states of consciousness. Cross-cultural hypotheses concerning altered states of consciousness are tested.

This article offers a detailed analysis of neuropsychopsiological processes involved in altered states of consciousness (ASC) in order to design and evaluate a psychophysiological model of trance states. Cross-cultural hypotheses concerning ASC are tested.
