Acerbi, Kendal, and Tehrani examine the relationship between population size and cultural complexity as measured by a non-technological cultural domain: folktales. Three measures of complexity for folktales are analyzed, 1) number of tale types, 2) number of narrative motifs, and 3) number of traits in variants of two international folktales. Findings suggest that the relationship between cultural complexity and population may depend on the domain, as different domains vary in cultural maintenance and transmission.

The myths, legends, and folktales of nearby groups tend to more alike than those of more distant groups. Three competing models attempt to explain this distribution of cultural traits: (1) vertical transmission, (2) horizontal transmission, and (3) independent innovation. The authors examine 18 Arctic hunter-gatherer groups to quantify the extent to which geographic distance, cultural ancestry, and effective population size predict overlap in folktale inventories.

This study investigates the strategic mode of competition in both games of strategy and folk talkes. Various significant relationships between games of strategy, folktales, social complexity, and child rearing variables are observed.

This book chapter tests new and pre-existing theories (Horton, Field, Bacon et al.) for the cause of variation in drinking across cultures. Folktale content is used to test psychological variables more directly than has been done previously. Folktale content is analyzed programmatically with an acknowledged error level of up to one-third. Results lend support to Field's 1962 theory that loose social organization facilitates drinking.

This book chapter (4) follows up suggestions from a previous chapter (3) by McClelland et.al. that in non-solidary societies heavy drinking is associated with conflict about personal power and alcohol provides a way of acting out impulses aimed at impacting others. Support was found for this theory using an analysis of words in folktales.

This study documents the phenomenon of the 'femme fatale' (a dangerous woman) and 'status fatale' (a dangerous man) cross-culturally. The 'femme fatale' motif is practically universal. Data supports the idea that emotional involvement, rather than sexual gratification, was the primary motivation for seeking out a stranger of the opposite sex. A literature review is provided.

Using a psychoanalytic-materialist approach, the author examines the possible effects of environmental unpredictability on the prevalence of unprovoked aggression by characters in folktales.

The authors compare language phylogenies and spatial distributions with folktale frequencies of Indo-European peoples in order to reconstruct their cultural transmission. A stronger association is found between folktale frequency and language phylogeny than has been proposed in earlier literature studies, indicating that vertical transmission is more influential on folktale distribution than horizontal transmission through spatial proximity. Finally, the frequencies of certain folktales appear to trace the ancestral divergences of Indo-European languages to a much deeper level than previously though, suggesting that folktales are representative of broader features of culture, rather than recent literary inventions.

This study examines aggression in folktales in relation to child socialization variables. The author suggests that punishment for aggression and aggression anxiety are related to how aggression is portrayed in folktales. Hypotheses are supported.

The authors of the present study investigate the psychological correlates of heavy drinking by using thematic content of folktales as a reflection of the cognitive processes of people in a given society. Subsequently, thematic variables are compared to ethnographic ratings in order to better understand how and if thought and reality correlate. Results are examined in the context of previous findings by other researchers, namely D. Horton (1943).
