Grateful Expectations: Cultural Differences in the Curvilinear Association between Age and Gratitude

Recent research suggests that the association between age and gratitude might be curvilinear—despite gratitude ostensibly being higher in middle-age, it might be lower in older adulthood. It is unclear if this curvilinear pattern of age differences in gratitude is found in other samples and whether its manifestation depends on contextual (i.e., national/cultural) characteristics. The current study examined cultural variation in the curvilinear effect of age on gratitude in a sample of over 4.5 million participants from 88 countries. Participants from countries with lower levels of human development, a shorter-term orientation, and higher levels of indulgence reported higher levels of gratitude. Cultural moderation effects were very small, suggesting that curvilinear effects of age on gratitude may be relatively comparable across cultures.

The Cultural Evolution of Language

Language is one of only a handful of human cultural systems that is both unique to our species, and universal. This chapter will focus on the cultural evolution of language, situating this alongside the phylogenetic and developmental timescales which also feed into the evolution of language. The chapter begins by outlining the relationship between the emergence of human language and the language faculty and the more rapid, ongoing processes of language change, which are often framed as predominantly cultural. In particular, previous work has emphasised how these timescales interact, and how cultural factors in particular shape which aspects of language exhibit broad cross-cultural variation or stability. This is followed by detailed evidence for this relationship from three domains, focusing on the role of cultural evolution in language as observed in natural language (both historical corpora and cross linguistic data), the cultural evolution of language in agent-based models, and finally, experimental studies of the cultural evolution of language. We conclude that the study of the cultural evolution of language forms an important data-rich model for the study of the evolution of cultural systems more generally, while also providing key insights into the specific dynamics of this uniquely human behaviour.

Awer Honey-Hunting Culture With Greater Honeyguides in Coastal Kenya

The remarkable mutualism between humans and greater honeyguides (Indicator indicator) is known still to thrive in only a few places in Africa. Here, we report on the honey-hunting culture of the marginalised Awer people in Kenya, historically a hunter-gatherer culture who today practise a mixed economy including significant amounts of foraging for wild foods. As part of a larger effort to document cross-cultural honey-hunting traditions in Africa, we interviewed six Awer honey-hunters to document their cultural practices. The interviewees reported that they depend on wild honey as a source of income, and that they readily seek the cooperation of honeyguides. Honey-hunting skills and the calls/whistles used to communicate with honeyguides are learnt from their fathers and other elders in village. The best time to honey-hunt is in the months following the big rains (August–December), when interviewees go out honey-hunting once a week on average. Honeyguides are not actively rewarded with wax, as it is believed that once a bird is fed it will not cooperate again for some time, and therefore after the honey harvest is complete, all remaining wax comb is buried. Honey-hunting practices are declining in this region, which interviewees attributed to drought and a lack of interest by the youth. These findings expand our understanding of how human-honeyguide mutualism persists across a range of human cultural variation.

Translating authorial presence

Of increasing interest in cross-linguistic variation in academic discourse is the way in which writers use first-person pronouns (FPPs) to promote their agency. While research has shown that language specific socio-cultural, rhetorical and lexico-grammatical factors impact levels of self-concealment vs. self-promotion, less attention has been paid to the ways in which translated texts are sensitive to these discoursal traditions. We address this gap by analyzing frequency, rhetorical use, and grammatical form of FPPs in a corpus of research article (RA) abstracts in biology written by Russian and international researchers in two peer-reviewed bilingual journals. Three subcorpora were analyzed: (i) L1 Russian abstracts; (ii) the same abstracts translated into English; (iii) abstracts by international biologists in English from the same journals. The FPP tokens were identified and their frequency, rhetorical use, and forms were compared. The results show significant differences between the corpora which supports previous findings on cross-cultural variation in authorial presence in research genres. The results also suggest that the translation not only transfers L1 linguistic code but also adds a stronger emphasis on author agency. Implications for translating RAs into English as an exercise in linguistic, cognitive, and pragmatic equivalence as well as for accommodating discourse conventions of English as a lingua franca of science are explored.

Universalities and cultural specificities of finger counting and montring: evidence from Amazon Tsimane’ people

Despite variety of cultures, our shared biology and the universality of finger counting suggests that numbers are embodied. Another lines of research show that numerical cognition might be bound to what our bodies are able to do. Differences in finger counting are apparent even within Western cultures. Relatively few indigenous cultures have been systematically analyzed in terms of traditional finger counting and montring (i.e., communicating numbers with fingers) routines. Even fewer studies used the same protocols across cultures, allowing for a systematic comparison of indigenous and Western finger counting routines. We analyze the finger counting and montring routines of Tsimane’ (N = 121), an indiginous people living in the Bolivian Amazon rainforest, depending on handedness, education level, and exposure to mainstream, industrialised Bolivian culture. Tsimane' routines are compared with those of German and British participants. Tsimane’ reveal a greater variation in finger counting and montring routines, which seems to be modified by their education level. We outline a framework on how different factors might affect cross-cultural and within-cultural variation in finger counting.

What is the expected human childhood? Insights from evolutionary anthropology

In psychological research, there are often assumptions about the conditions that children expect to encounter during their development. These assumptions shape prevailing ideas about the experiences that children are capable of adjusting to, and whether their responses are viewed as impairments or adaptations. Specifically, the expected childhood is often depicted as nurturing and safe, and characterized by high levels of caregiver investment. Here, we synthesize evidence from history, anthropology, and primatology to challenge this view. We integrate the findings of systematic reviews, meta-analyses, and cross-cultural investigations on three forms of threat (infanticide, violent conflict, and predation) and three forms of deprivation (social, cognitive, and nutritional) that children have faced throughout human evolution. Our results show that mean levels of threat and deprivation were higher than is typical in industrialized societies, and that our species has experienced much variation in the levels of these adversities across space and time. These conditions likely favored a high degree of phenotypic plasticity, or the ability to tailor development to different conditions. This body of evidence has implications for recognizing developmental adaptations to adversity, for cultural variation in responses to adverse experiences, and for definitions of adversity and deprivation as deviation from the expected human childhood.

Mexican Emotional Speech Database Based on Semantic, Frequency, Familiarity, Concreteness, and Cultural Shaping of Affective Prosody

In this paper, the Mexican Emotional Speech Database (MESD) that contains single-word emotional utterances for anger, disgust, fear, happiness, neutral and sadness with adult (male and female) and child voices is described. To validate the emotional prosody of the uttered words, a cubic Support Vector Machines classifier was trained on the basis of prosodic, spectral and voice quality features for each case study: (1) male adult, (2) female adult and (3) child. In addition, cultural, semantic, and linguistic shaping of emotional expression was assessed by statistical analysis. This study was registered at BioMed Central and is part of the implementation of a published study protocol. Mean emotional classification accuracies yielded 93.3%, 89.4% and 83.3% for male, female and child utterances respectively. Statistical analysis emphasized the shaping of emotional prosodies by semantic and linguistic features. A cultural variation in emotional expression was highlighted by comparing the MESD with the INTERFACE for Castilian Spanish database. The MESD provides reliable content for linguistic emotional prosody shaped by the Mexican cultural environment. In order to facilitate further investigations, a corpus controlled for linguistic features and emotional semantics, as well as one containing words repeated across voices and emotions are provided. The MESD is made freely available.

Cultural Variation in Aggressive Behavior: A Cross-Cultural Comparison of Students’ Exposure to Bullying Across 32 Countries

Introduction. The prevalence rates of bullying vary significantly across countries and continents. Specifically, UNESCO estimates that the prevalence rates vary from 22.8% (Central America) to 48.2% (Sub-Saharan Africa). Recently, these differences among countries and regions have been attributed to culture- and country-level variables. Thus, the first purpose of this study is to examine the comparability of bullying in schools across countries. Secondly, a cross-cultural comparison of the latent mean scores of bullying is implemented. Method. The data of 286,481 adolescent students (M=15.78, SD=0.29) from 32 countries were analyzed using multilevel confirmatory factor analyses (MLCFA) and multigroup factor alignment. Results. Results indicated that the meaning of bullying is equivalent within and between cultures. However, cross-cultural differences in bullying are apparent. East Asian countries have the lowest latent means of bullying, while Southeast Asian countries have the highest means. Anglo-Saxon, Eastern European, Mediterranean, South American, and Middle East countries displayed rather higher scores. Discussion and Conclusion. These findings underscore the existence of cross-cultural differential responding in bullying measures. Further, the implicit role of culture as an important variable that determines the rates of bullying is underscored.
