Games and enculturation: A cross-cultural analysis of games and values in Austronesia

While most animals play, only humans play games. As animal play serves to teach offspring important life-skills in a safe scenario, human games might, in similar ways, teach important culturally relevant skills. Humans in all cultures play games; however, it is not clear whether variation in the characteristics of games across cultural groups is related to group-level attributes. Here we investigate specifically whether the cooperativeness of games covaries with socio-ecological differences across cultural groups. We hypothesize that cultural groups that engage in frequent inter-group conflict, cooperative sustenance acquisition, or that have less stratified social structures, might more frequently play cooperative games as compared to groups that do not share these characteristics. To test these hypotheses, we gathered data from the ethnographic record on 25 ethnolinguistic groups in the Austronesian language family. We show that cultural groups with higher levels of inter-group conflict and cooperative land-based hunting play cooperative games more frequently than other groups. Additionally, cultural groups with higher levels of intra-group conflict play competitive games more frequently than other groups. These findings indicate that games are not randomly distributed among cultures, but rather relate to the socio-ecological settings of the cultural groups that practice them. We argue that games serve as training grounds for group-specific norms and values and thereby have an important function in enculturation during childhood. Moreover, games might server an important role in the maintenance of cultural diversity.Introduction Children’s play Games Possible drivers of cooperative goal structures - Interdependence in foraging. - Intra- and inter-group conflict.

The Austronesian game taxonomy: A cross-cultural dataset of historical games

Humans in most cultures around the world play rule-based games, yet research on the content and structure of these games is limited. Previous studies investigating rule-based games across cultures have either focused on a small handful of cultures, thus limiting the generalizability of findings, or used cross-cultural databases from which the raw data are not accessible, thus limiting the transparency, applicability, and replicability of research findings. Furthermore, games have long been defined as competitive interactions, thereby blinding researchers to the cross-cultural variation in the cooperativeness of rule-based games. The current dataset provides ethnographic, historic information on games played in cultural groups in the Austronesian language family. These game descriptions (Ngames = 907) are available and codeable for researchers interested in games. We also develop a unique typology of the cooperativeness of the goal structure of games and apply this typology to the dataset. Researchers are encouraged to use this dataset to examine cross-cultural variation in the cooperativeness of games and further our understanding of human cultural behaviour on a larger scale.Background and summary Methods - Defining games. - Defining the goal structure of games Search criteria and methodology - eHRAF - Pulotu - American Anthropologist - The Journal of the Polynesian Society - Additional sources Data records - Variable definitions - Descriptive statistics of games Technical validation - Cultural group identifiers - Record linkage - Filtering and coding of games - Austronesian language phylogeny Research opportunitie

Playing a cooperative game promotes preschoolers’ sharing with third-parties, but not social inclusion

This study examined the effect of gaming context on young children’s prosocial behaviors. Dyads of 4- to 5-year-old children (N = 96) played the same game cooperatively, competitively, or solitarily. After playing the game for a total of ten minutes, sharing with and social inclusion of uninvolved third-parties as well as free play with previous co-players was observed. Children shared less with third-parties after playing the game competitively than after playing it cooperatively. Playing a solitary game resulted in intermediate levels of sharing. The structure of the game did not differentially impact measures of social inclusion or free play

Adult instruction limits children’s flexibility in moral decision making

Children’s moral behavior is guided, in part, by adults teaching children how to treat others. However, when circumstances change, such instructions may become either unhelpful or limiting. In the current study, 48 dyads of 5-year-olds played a collaborative game and either (a) received an instruction by an adult to share the spoils of the game equally, (b) did not receive any instruction (but still chose to share equally), or (c) agreed between themselves on a rule to share equally. Afterward, each child played with a new partner who was needier or worked harder in his or her collaboration and so plausibly deserved more than just half of the spoils. Results showed that children who were instructed by an adult shared less with their more deserving partner than children who did not receive any instruction. Thus, moral instruction by adults may, in some circumstances, make children more rigid in their moral decisions

Allogromiid foraminifera and gromiids from under the Ross Ice Shelf: morphological and molecular diversity

Allogromiid foraminifera and gromiids constitute an important but poorly known component of the meiobenthos in high-latitude marine settings. Here, we present a first report on the diversity of these protists, together with an account of co-occurring invertebrate taxa, in a sample of sea floor sediment from a water depth of 923 m under the Ross Ice Shelf. Light microscopy of sieved sediment yielded 14 allogromiid foraminifera and three Gromia spp. morphotypes. We also obtained 36 partial small subunit rDNA sequences of allogromiids, including 19 sequences of individual isolates and 17 sequences from environmental DNA samples. Phylogenetic analyses of the obtained sequences identified 18 phylotypes, of which seven were closely related to previously sequenced allogromiids, while 11 represented new lineages. Our results demonstrate that a rich meiofaunal assemblage is present under the Ross Ice Shelf, 12 km from the open ocean. Molecular phylogenetic analyses of these allogromiid foraminifera point to the endemic character of the Ross Ice Shelf assemblage; however, more extensive sampling of the molecular diversity of this group of foraminifera in the Antarctic deep sea is necessary to confirm this conclusion
