Ecogeography of group size suggests differences in drivers of sociality among cooperatively breeding fairywrens

Cooperatively breeding species exhibit a range of social behaviors associated with different costs and benefits to group-living, often in association with different environmental conditions. For example, species in which collective-care of offspring reduces the cost of reproduction are more common in harsh environments (true cooperative breeding), while species that collectively defend resources are present in benign environments (family-living). Here, we examine whether environment also shapes sociality within cooperatively-breeding species. We illustrate that Purple-backed Fairywrens, which primarily gain intrinsic, or collective-care benefits, have larger groups in hot, dry environments and smaller groups in cool, wet environments, whereas Superb Fairywrens which primarily gain extrinsic, or resource defense benefits, exhibit the opposite trend. We suggest differences in the costs and benefits of sociality contribute to these opposing ecogeographic patterns, demonstrating that comparisons of intraspecific patterns of social variation across species can provide insight into how ecology shapes transitions between social systems.

Regional variation in British English voice quality

This study considers regional variation of voice quality in two varieties of British English – Southern Standard British English and West Yorkshire English. A comparison of voice quality profiles for three closely related but not identical northern varieties within West Yorkshire is also considered. Our findings do not contradict the small subset of previous research which explored regional and/or social variation in voice quality in British English insofar as regionality may play a small role in a speaker’s voice quality profile. However, factors such as social standing and identity could perhaps be even more relevant. Even when considering homogeneous groups of speakers, it is not the case that there is a cohesive voice quality profile that can be attached to every speaker within the group. The reason for this, we argue, is the speaker-specificity inherent in voice quality.

Das laienlinguistische Konzept von Variation.

The following article consists of three parts: First, the context in which speakers live is sketched phenomenologically. These life-worlds are described as language-worlds, since language, according to the premise, is apriori and thus directly relevant. Subsequently, the focus is on the speakers as actors within the language-worlds. A cognitive-realistic model is presented to describe their lay-linguistic knowledge, the center of what is called epistemicon. Based on this, the third part of the article outlines an empirical study that surveys the linguistic laypersons’ knowledge on variation. It can be shown that although knowledge of regional variation is most abundant, aspects of functional and social variation also play a role. The final diagnosis is that the conceptualization of variation is fundamental to the linguistic worlds of linguistic laypersons.

Tam pam pam pam and mi – fa – sol: constituting musical instructions through multimodal interaction in orchestra rehearsals

Using multimodal (inter)action/conversation analysis, the present contribution inventories the repertoire of higher-level actions that constitute musical instruction in orchestra rehearsals. The study describes the modal complexity of the instructional actions as built from a varied combination of speech, gesture, gaze, vocalizing and body posture/movement. A high modal intensity of speech and vocalizing is explained with recourse to their contextually useful modal reaches. While some modes, like vocalizing and body posture appear to be action-specific, others turn out to be pervasive default modes. Besides modal intensity, the study also attends to the transitioning between higher-level actions through gaze and the role of the score as frozen action. The analyses help demystify orchestra rehearsals as a special type of professional communicative interaction, which builds on a rich multimodal texture motivated by recurring instructional functions. The methodological rationale demonstrated will be suited to exploring the social variation of instructional interaction in orchestra rehearsals.

Yawning Is More Contagious in Pregnant Than Nulliparous Women

Contrary to spontaneous yawning, which is widespread in vertebrates and probably evolutionary ancient, contagious yawning—yawning triggered by others’ yawns—is considered an evolutionarily recent phenomenon, found in species characterized by complex sociality. Whether the social asymmetry observed in the occurrence of contagious yawning is related to social and emotional attachment and may therefore reflect emotional contagion is a subject of debate. In this study we assessed whether yawn contagion was enhanced in pregnant women, a cohort of subjects who develop prenatal emotional attachment in preparation for parental care, via hormonal and neurobiological changes. We predicted that if yawn contagion underlies social and emotional attachment, pregnant women would be more likely to contagiously yawn than nonpregnant, nulliparous women of reproductive age. We gathered data in two different settings. In the experimental setting, 49 women were exposed to video stimuli of newborns either yawning or moving their mouth (control) and we video-recorded the women during repeated trials to measure their yawning response. In the naturalistic setting, 131 women were observed in a social environment and their yawning response was recorded. We tested the factors influencing the yawning response, including the reproductive status (pregnant vs. not pregnant). In both settings, yawn contagion occurred significantly more in pregnant than nonpregnant women. By showing that pregnant women were most likely to respond to others’ yawns, our results support the hypothesis that the social variation observed in yawn contagion may be influenced by emotional attachment and that yawning in highly social species might have been coopted for emotional contagion during evolution.

A-prefixing in Linguistic Atlas Project data

This paper discusses the linguistic, social, and geographic distribution of a-prefixing data in the Linguistic Atlas Project (LAP) of North America. Over 3800 instances of the a-prefix were extracted for analysis from the LAP interview data of 1527 speakers from across the United States, collected between 1931 and 2006. While the LAP a-prefix data do not generally deviate from patterns observed in the sociolinguistic literature, they do offer a more nuanced picture of infrequent prefixed forms, including uncommon constructions and verbs that appear as a-prefixed forms less frequently. A-prefixers in LAP tended to be white men, although it should be noted that between 30-47% of the female speakers in four of the surveyed LAP projects also used this feature. The geographic distribution of the feature suggests that the a-prefix is not Southern so much as it is Eastern, with pockets of lesser and greater usage as one moves westward across the country. Additionally, this paper casts the a-prefix as a rural phenomenon, rather than as a strictly Southern one, which opens the door to discussions of the feature as a means of indexing participation in (or affinity for) a rural lifestyle. Overall, this paper demonstrates that LAP data are a tremendous resource and a key piece of the puzzle of understanding regional and social variation.

The development of locative relative markers

The accessibility hierarchy was first proposed by Keenan & Comrie (1977) to describe the cross-linguistic distribution of relative markers in terms of likelihood of relativization of different syntactic roles. The hierarchy is also commonly believed to reflect constraints on possible changes in the domain of relativization. For example, the hierarchy predicts that locative relatives that develop into general relativizers should expand their functional range in a step-by-step fashion from lower to higher roles. In this paper, we revise existing claims about the diachrony of locative relatives. In doing so, we survey known cases of locative relatives that develop into general relativizers and we also discuss data from linguistic variation in non-standard varieties in European languages, with a focus on social variation in Italian. As we argue, data from Italian suggests that another possible cline of development of locative relatives should be acknowledged, that is, locative > concern > subject.

Human social organization during the Late Pleistocene: Beyond the nomadic-egalitarian model

Many researchers assume that until 10-12,000 years ago, humans lived in small, mobile, relatively egalitarian bands composed mostly of kin. This “nomadic-egalitarian model” informs evolutionary explanations of behavior and our understanding of how contemporary societies differ from those of our evolutionary past. Here, we synthesize research challenging this model and propose an alternative, the diverse histories model, to replace it. We outline the limitations of using recent foragers as models of Late Pleistocene societies and the considerable social variation among foragers commonly considered small-scale, mobile, and egalitarian. We review ethnographic and archaeological findings covering 34 world regions showing that non-agricultural peoples often live in groups that are more sedentary, unequal, large, politically stratified, and capable of large-scale cooperation and resource management than is normally assumed. These characteristics are not restricted to extant Holocene hunter-gatherers but, as suggested by archaeological findings from 27 Middle Stone Age sites, likely characterized societies throughout the Late Pleistocene (until c. 130 ka), if not earlier. These findings have implications for how we understand human psychological adaptations and the broad trajectory of human history.

That’s Cool. Computational Sociolinguistic Methods for Investigating Individual Lexico-grammatical Variation

The present study deals with variation in the use of lexico-grammatical patterns and emphasizes the need to embrace individual variation. Targeting the pattern that’s adj (as in that’s right, that’s nice or that’s okay) as a case study, we use a tailor-made Python script to systematically retrieve grammatical and semantic information about all instances of this construction in BNC2014 as well as sociolinguistic information enabling us to study social and individual lexico-grammatical variation among speakers who have used this pattern. The dataset amounts to 4,394 tokens produced by 445 speakers using 159 adjective types in 931 conversations. Using detailed descriptive statistics and mixed-effects regression models, we show that while the choice of some adjectives is partly determined by social variables, situational and especially individual variation is rampant overall. Adopting a cognitive-linguistic perspective and relying on the notion of entrenchment, we interpret these findings as reflecting individual speakers' routines. We argue that computational sociolinguistics is in an ideal position to contribute to the data-driven investigation of individual lexico-grammatical variation and encourage computational sociolinguists to grab this opportunity. For the routines of individual speakers ultimately both underlie and compromise systematic social variation and trigger and steer well-known types of language change including grammaticalization, pragmaticalization and change by invited inference.

Research of Intra-generational Heterogeneity in the Life Course Paradigm

The article discusses methodological issues how to explore and interpret intra-cohort and intragenerational variability within the theoretical framework of the life-course paradigm. Starting with an assumption that social variation within one generation and its permanence over the time should be explained as a sociological fact, we propose methodological guidelines how to approach the topic of intragenerational variability in the analysis of narratives of family histories. To demonstrate how to analyse and read empirical data, we present three life stories of women, born in 1936, who migrated to Klaipėda Region, Lithuania, after World War II. The narrative analysis, supported with demographical data, shows how the early experience of socialization is eventually translated into ethnic differences and solidifies the structure of intragenerational variability.
