This study examines the relationship between satisfaction of early oral and dependence needs and concern with affection in adulthood. Data showed significant support for an association between the satisfaction of early oral needs (but not the satisfaction of dependence needs) and concern for affection in adulthood.

This article expands on Buss's (1989) study of the differences in male and female mate preferences in Western folktale characters by adding non-Western data. The new results show support for Buss's original findings.

This study examines different sources of marital stability. Authors find that subsistence dependence between partners provides marital stability and where subsistence dependence is not important, romantic love substitutes as a source of marriage stability.

This study explores the relationship between property ownership, pair bonding, and sex as predictors of romantic jealousy. The results of an unpublished cross-cultural study are presented in support of the theory.

This paper presents research on the factors that promote romantic love as a basis for marriage in non-industrial societies. After a discussion of the previous literature on romantic love in ethnographic societies, the authors used the SCCS, EA, and data from eHRAF to create a data set of 109 cultures and then utilized multiple ordinal regression to test the relationship between different types of families and post-marital residence practices and the importance of romantic love in marriage. The findings show that monogamy is significantly correlated with romantic love, while nuclear family organization and neolocal post-marital residence are not significantly correlated. The presence of polygyny is found to lower the probability of romantic love being a basis for marriage. These findings contradict previous research, which found a relationship between non-neolocal post-marital residence and the presence of romantic love in marriage.

The authors of this exploratory study tested predictions from five different theoretical models for the evolution of ethnoscientific expertise. They claim support for three of the models. They then compared cultural variables and their five models to three different knowledge domains: conceptual (unable to be easily observed), motor (easily observable), and medicinal. Their results indicate that their cultural transmission model is associated with the motor knowledge domain and that their proprietary knowledge model is associated with the medicinal knowledge domain.

This book examines population growth rate and its correlates by testing 274 hypotheses (derived from multiple theories) with an 18-society sample. Forty-one of these hypotheses were significant at the .05 level, leading the author to accept these relationships as reflective of the real world. The 274 hypotheses are grouped into 51 broader hypotheses, and marked by (*) where relationships are significant as designated by the author or by significance p < 0.05.

Based on work by Rosenblatt (1966), this article tests a hypothesis relating sexual freedom to romantic love. Findings suggest a relationship between premarital and extramarital sexual permissiveness equality for women and men and romantic love.

This article uses factor analysis to identify the key variables underlying the many cross-cultural associations reported by Textor (1967). Twelve factors are identified.

The present study aims to assess the reliability of Simmons' (1937) database of 109 variables coded for 71 societies. Simmons' data was evaluated against matching societies and variables from Murdock's (1967) Ethnographic Atlas. The ultimate purpose of Rudmin's analysis is to identify the features of societies that are correlated with the private ownership of property. To do so, Simmons' reliable variables are tested against four measures of property ownership, two from Simmons and two from Murdock. Rudmin discusses results and speculates why certain clusters of societal variables correlate with private property ownership.
