Abstract Certain historical processes and sign language ideologies have led to the dissemination of American Sign Language (ASL) signs throughout Southeast Asia via deaf education projects, international development interventions, and tourism, notably in Cambodia and Indonesia. These ideologies normalized attempts to develop standardised sign systems based on national spoken languages and the introduction of signs from foreign sign languages, especially ASL. This history has shaped and mobilized ideas among deaf sign language users about language contact, the spread of hegemonic national sign languages, and the vitality of sign languages outside of the US and western Europe. Some of these ideologies manifest in deaf signers’ concerns about the vitality of what are often perceived to be non-hegemonic sign languages (e.g., sign languages that are not ASL, Auslan, or BSL) and language practices. By examining discourses and practices in the context of encounters between deaf tourists and deaf leaders in Bali, this article approaches larger questions about the territorialization of sign languages, linguistic boundaries, language contact, and sign language vitality.

This article investigates how Arabic texts reached multilingual audiences in North India in the eighteenth century. Drawing on a remarkable treatise on translating the Qur’an into Persian by the Delhi intellectual Shāh Walī-Allāh (d. 1176/1762), it argues that so-called “interlinear” translations functioned to preserve the sound of Arabic utterances as well as their meaning. By anchoring another language to Arabic utterances, these translations also reified symbolic hierarchies between Arabic and languages used to translate it. Walī-Allāh’s understanding of translatability was closely tied up with notions of Qur’anic structure (naẓm) and the sonic qualities of the Arabic language, but also informed by a sensitivity to linguistic difference in the multilingual society he lived in.

This paper focuses on the verbal inflection chain of Siyuewu Khroskyabs, a Gyalrongic language (Trans-Himalayan). Siyuewu Khroskyabs goes against two general typological tendencies: first, as an SOV language, it shows an overwhelming preference for prefixes, which is rarely reported typologically; second, the inflectional prefixes in the outer slots are older than those in the inner slots, which is the reverse case of most languages. In this paper, I will first identify distinct historical layers within the inflectional prefixes, and then focus on two of the prefixes, də- ‘even’ and ɕə- ‘q’ whose evolutionary pathways are relatively clear. The essential part of the hypotheses is that the prefixes originate from enclitics which could be attached to the end of a preverbal chain, originally loosely attached to the verb stem. The preverbal chain later became tightly attached to the verbal stem and eventually became a part of it as a chain of prefixes. As a result, the original enclitics are reanalysed as prefixes. The integration of preverbal morphemes is responsible for the prefixing preference in Modern Siyuewu Khroskyabs. However, despite this superficial prefixing preference, Siyuewu Khroskyabs underlyingly favours postposed morphemes. By following the general suffixing tendency, this language finally managed to create a typologically rare, overwhelmingly prefixing verbal template. 1 Introduction 1.1 The suffixing preference 1.2 Correlation between affix age and position 1.3 The betrayal of Khroskyabs 2 The prefixing preference of Siyuewu Khroskyabs 3 Morphophonology of the Khroskyabs inflectional chain 3.1 Autonomous markers in the first slots (R-1, R-2, IRR-2) 3.1.1 Orientational prefixes 3.1.2 Negative markers 3.1.3 Interrogative â 3.2 Non-autonomous markers (R-1, R-2, IRR-1, IRR-2) 3.2.1 Inverse marker 3.2.2 Interrogative â 3.2.3 Irrealis â 3.2.4 HL tone conditional 3.3 Prefixes undergoing fusion (R-3 and IRR-3) 3.3.1 Sensory râ 3.3.2 Attenuative imperative ^o- 3.3.3 Conditional zâ 3.4 Wordhood of the Siyuewu verb 4 The historical layers of the Siyuewu inflectional chain 4.1 Degree of fusion and compatibility 4.2 Productivity and usage constraints 4.2.1 Orientational prefixes 4.2.2 Negative prefixes 4.2.3 â- ‘Q’ and ‘Q’ 4.2.4 Conditional markers and the irrealis category 4.2.5 Productive prefixes 4.2.6 Summary 4.3 Cross-Gyalrongic comparison 4.3.1 Orientational prefixes 4.3.2 Interrogative â 4.3.3 Irrealis â 4.3.4 Negative prefixes 4.3.5 Inverse marker 4.3.6 Attenuative imperative ^mo- 4.4 Identification of the historical layers 5 How prefixes are integrated 5.1 da- ‘even’ and =da ‘also, even’ 5.2 ‘Q’ and ‘Q’ 5.3 Integration of da- ‘even’ 5.3.1 Semantic narrowing from =da ‘also, even’ to da- ‘even’ 5.3.2 Simplification of double verb construction and clitic reassignment 5.4 Integration of ‘Q’ 5.5 An alternative hypothesis 6 Discussion and conclusion

Summary Can preverbal infants utilize logical reasoning such as disjunctive inference? This logical operation requires keeping two alternatives open (A or B), until one of them is eliminated (if not A), allowing the inference: B is true. We presented to 10-month-old infants an ambiguous situation in which a female voice was paired with two faces. Subsequently, one of the two faces was presented with the voice of a male. We measured infants' preference for the correct face when both faces and the initial voice were presented again. Infant pupillary response was measured and utilized as an indicator of cognitive load at the critical moment of disjunctive inference. We controlled for other possible explanations in three additional experiments. Our results show that 10-month-olds can correctly deploy disjunction and negation to disambiguate scenes, suggesting that disjunctive inference does not rely on linguistic constructs. Highlights • 10-month-old infants have no logical operators in their lexicon • Nevertheless, they can use logical deduction in case of an ambiguous situation • They correctly deduce which faces and voices are paired through disjunctive inference • Infants' performance in this task can be followed by measuring their pupil dilation Biological Science, Neuroscience, Cognitive neuroscience, Behavioral Neuroscience Graphical abstract

Abstract Sound patterns in heritage languages are often highly variable, potentially with influences from majority languages. Yet, the core phonological system of the heritage language tends to remain stable. This article considers variation in the phonetic and phonological patterns of /r/ in American Norwegian heritage language speakers from neighboring communities in western Wisconsin, in the Upper Midwestern United States. Drawing on acoustic data from speakers born between 1879 and 1957, I examine the distribution of four rhotic allophones, including an English-like approximant, over time. These data reveal an increase of approximants that is structured within the Norwegian phonological system and its processes. Furthermore, analyzing these changes with the proposed modular framework provides clarity for how heritage language sound systems do and do not change under contact and contributes to our understanding of the asymmetric phonetic and phonological heritage language patterns.

It is known that, although the level of light is the primary determinant of pupil size, cognitive factors can also affect pupil diameter. It has been demonstrated that photographs of the sun produce pupil constriction independently of their luminance and other low-level features, suggesting that high-level visual processing may also modulate pupil response. Here, we measure pupil response to artistic paintings of the sun, moon, or containing a uniform lighting, that, being mediated by the artist's interpretation of reality and his technical rendering, require an even higher level of interpretation compared with photographs. We also study how chromatic content and spatial layout affect the results by presenting grey-scale and inverted versions of each painting. Finally, we assess directly with a categorization test how subjective image interpretation affects pupil response. We find that paintings with the sun elicit a smaller pupil size than paintings with the moon, or paintings containing no visible light source. The effect produced by sun paintings is reduced by disrupting contextual information, such as by removing color or manipulating the relations between paintings features that make more difficult to identify the source of light. Finally, and more importantly, pupil diameter changes according to observers' interpretation of the scene represented in the same stimulus. In conclusion, results show that the subcortical pupillary response to light is modulated by subjective interpretation of luminous objects, suggesting the involvement of cortical systems in charge of cognitive processes, such as attention, object recognition, familiarity, memory, and imagination.

AbstractPeter Godfrey-Smith’s Metazoa and Joseph LeDoux’s The Deep History of Ourselves present radically different big pictures regarding the nature, evolution and distribution of consciousness in animals. In this essay review, I discuss the motivations behind these big pictures and try to steer a course between them.

Historians tend to view public health as a quintessentially modern phenomenon, enabled by the emergence of representative democracies, centralised bureaucracies and advanced biomedicine. While social, urban and religious historians have begun chipping away at the entrenched dichotomy between pre/modernity that this view implies, evidence for community prophylactics in earlier eras also emerges from a group of somewhat unexpected sources, namely military manuals. Texts composed for (and often by) army leaders in medieval Latin Europe, East Rome (Byzantium) and other premodern civilisations reflect the topicality of population-level preventative healthcare well before the nineteenth century, thereby broadening the path for historicising public health from a transregional and even global perspective. Moreover, at least throughout the Mediterranean world, military manuals also attest the enduring appeal of Hippocratic and Galenic prophylactics and how that medical tradition continued for centuries to shape the routines and material culture of vulnerable communities such as armies.
