Abstract
Development tests are widely used in the scope of cross-cultural and comparative research to support intervention studies and health care projects concerning early childhood development. Therefore, it is crucial to use culturally sensitive assessment tools. A culturally adapted version of the German development test FREDI 0-3 (Maehler, Cartschau, & Rohleder, 2016) was used to assess a German (n = 405) and an Indian (n = 2075) sample of children between ten and thirty-two months. Measurement invariance indicates psychometric equivalence of a construct across groups and is a prerequisite for test applications in a cross-cultural setting. Confirmatory factor analyses for single cohorts per age group and multi-group measurement invariance analyses were used to examine the data equivalence of the test across groups. Weak measurement invariance could be established across both groups in all four age groups (10-14; 15-21; 22-26; 27-32 months) suggesting that the development factor was measured in the same way in both groups and accounted similarly for performance differences in the developmental subdomains for the German and the Indian sample. However, scalar and strict measurement invariance were violated in almost all group comparisons suggesting differences in scale difficulty and reliability across the German and the Indian sample. This suggests that a culture-sensitive adaptation process like it was carried out within this project is necessary but not sufficient in order to create a culturally comparable development test. It is essential to always carry out measurement invariance testing to determine the psychometric equivalence of the test and additionally reduce linguistic and cultural bias through an adaption process based on empirical proven methodological principles.

Abstract
Caretakers tend to repeat themselves when speaking to children, either to clarify their message or to redirect wandering attention. This repetition also appears to support language learning. For example, words that are heard more frequently tend to be produced earlier by young children. However, pure repetition only goes so far; some variation between utterances is necessary to support acquisition of a fully productive grammar. When individual words or morphemes are repeated, but embedded in different lexical and syntactic contexts, the child has more information about how these forms may be used and combined. Corpus analysis has shown that these partial repetitions frequently occur in clusters, which have been coined variation sets. More recent research has introduced algorithms that can extract these variation sets automatically from corpora with the goal of measuring their relative prevalence across ages and languages. Longitudinal analyses have revealed that rates of variation sets tend to decrease as children get older. We extend this research in several ways. First, we consider a maximally diverse sample of languages, both genealogically and geographically, to test the generalizability of developmental trends. Second, we compare multiple levels of repetition, both words and morphemes, to account for typological differences in how information is encoded. Third, we consider several additional measures of development to account for deficiencies in age as a measure of linguistic aptitude. Fourth, we examine whether the levels of repetition found in child-surrounding speech is greater or less than what would have been expected by chance. This analysis produced a new measure, redundancy, which captures how repetitive speech is on average given how repeititive it could have been. Fifth, we compare rates of repetition in child-surrounding and adult-directed speech to test whether variation sets are especially prevalent in child-surrounding speech. We find that (1) some languages show increases in repetition over development, (2) true estimates of variation sets are generally lower than or equal to random baselines, (3) these patterns are largely convergent across developmental indices, and (4) adult-directed speech is reliably less redundant, though in some cases more repetitive, than child-surrounding speech. These results are discussed with respect to features of the corpora, typological properties of the languages, and differential rates of change in repetition and redundancy over children's development.

Abstract
The outstanding property of human language is its diversity, and yet acquisition data is only available for three percent of the world's 6000+ spoken languages. Due to the rapid pace of language loss, it may not be possible to document how children acquire half of the world's indigenous languages in as little as two decades. This loss permanently diminishes the scope of acquisition theory by removing its empirical base. In the face of pervasive language loss, the question of how best to document the language of the last children to acquire indigenous languages assumes critical importance. A collaborative effort by researchers is required to identify the most efficient procedures for documenting children's language, and share them worldwide. This paper makes the case for documenting diversity and outlines steps needed to accomplish this goal.

Abstract
This article introduces the LITMUS-MAIN (Language Impairment Testing in Multilingual Settings-MAIN) and motivates the adaptation of this instrument into Chinese languages and language pairs involving a Chinese language, namely Cantonese, Mandarin, Kam, Urdu. We propose that these new adapted protocols not only contribute to the theoretical discussion on story grammar and widen the evidential base of MAIN to include more languages in studying bilinguals, they also offer new methods of assessing language development in young children that have the potential to tease apart the effects of language impairment and bilingualism and improve the identification of Developmental Language Disorder. These new protocols are the first tools to be designed for the dual assessment of language skills in these particular languages, in particular narrative skills in bilingual children speaking these languages. By catering to under-researched languages and over-looked groups of bilingual children, these new tools could improve the clinical management for certain bilingual ethnic minority children such as Urdu-Cantonese and Kam-Mandarin bilinguals, as well as promote the study of these groups and their acquisition issues. Advances in understanding the theoretical and acquisition issues in childhood bilingualism can also be made possible using these new tools.

Abstract
Many Western industrialized nations have high levels of ethnic diversity but to date there are very few studies which investigate prelinguistic and early language development in infants from ethnic minority backgrounds. This study tracked the development of infant communicative gestures from 10 to 12 months (n = 59) in three culturally distinct groups in the United Kingdom and measured their relationship, along with maternal utterance frequency and responsiveness, to vocabulary development at 12 and 18 months. No significant differences were found in infant gesture development and maternal responsiveness across the groups, but relationships were identified between gesture, maternal responsiveness, and vocabulary development.

Abstract
Recent theoretical work in developmental psychology suggests that humans are predisposed to align their mental states with those of other individuals. One way this manifests is in cooperative communication; that is, intentional communication aimed at aligning individuals' mental states with respect to events in their shared environment. This idea has received strong empirical support. The purpose of this paper is to extend this account by proposing an integrative model of the biobehavioral dynamics of cooperative communication. Our formulation is based on active inference. Active inference suggests that action-perception cycles operate to minimize uncertainty and optimize an individual's internal model of the world. We propose that humans are characterized by an evolved adaptive prior belief that their mental states are aligned with, or similar to, those of conspecifics (i.e., that 'we are the same sort of creature, inhabiting the same sort of niche'). The use of cooperative communication emerges as the principal means to gather evidence for this belief, allowing for the development of a shared narrative that is used to disambiguate interactants' (hidden and inferred) mental states. Thus, by using cooperative communication, individuals effectively attune to a hermeneutic niche composed, in part, of others' mental states; and, reciprocally, attune the niche to their own ends via epistemic niche construction. This means that niche construction enables features of the niche to encode precise, reliable cues about the deontic or shared value of certain action policies (e.g., the utility of using communicative constructions to disambiguate mental states, given expectations about shared prior beliefs). In turn, the alignment of mental states (prior beliefs) enables the emergence of a novel, contextualizing scale of cultural dynamics that encompasses the actions and mental states of the ensemble of interactants and their shared environment. The dynamics of this contextualizing layer of cultural organization feedback, across scales, to constrain the variability of the prior expectations of the individuals who constitute it. Our theory additionally builds upon the active inference literature by introducing a new set of neurobiologically plausible computational hypotheses for cooperative communication. We conclude with directions for future research.

Abstract
This study analyzes how others engage rural and urban Mozambican infants during naturalistic observations, and how the proportion of time spent in different engagements relates to infants' language development over the second year of life. Using an extended version of Bakeman and Adamson's (1984) categorization of infant engagement, we investigated to what extent a detailed analysis of infant engagement can contribute to our understanding of vocabulary development in natural settings. In addition, we explored how the different infant engagements relate to vocabulary size, and how these differ between the two communities. Results show that rural infants spend significantly more time in forms of solitary engagement, whereas urban infants spend more time in forms of triadic joint engagement. In regard to correlations with reported productive vocabulary, we find that dyadic persons engagement (i.e. interactions not about concrete objects) has positive correlations with vocabulary measures in both rural and urban communities. In addition, we find that triadic coordinated joint attention has a positive relationship with vocabulary in the urban community, but a contrasting negative correlation with vocabulary in the rural community. These similarities and differences are explained, based upon the parenting beliefs and socialization practices of different prototypical learning environments. Overall, this study concludes that the extended categorization provides a valuable contribution to the analysis of infant engagement and their relation to language acquisition, especially for analyzing naturalistic observations as compared to semi-structured studies. Moreover, with respect to vocabulary development, Mozambican infants appear to benefit strongest from dyadic Persons engagement, while they do not necessarily benefit from joint attention, as tends to be the case for children from industrial, developed communities.

Abstract
This article focuses on the development of forms of vitality play, a recently described type of play, and links it to the development of symbolic play, one of the most studied types of play in developmental psychology. Two adult-infant dyads were videotaped longitudinally during in-house free play meetings every 15 days during the third year of life. Convergence technique was applied in order to accelerate the longitudinal study. A total of 17h 48min were registered in 28 sessions. An observational code with categories of forms of vitality play (a non-figurative play frame in which child and adult play together with the dynamics of their own movements and sounds in a repetition-variation form), symbolic play, and categories of combined patterns of both types of play was applied. The rate of each play was calculated for different age periods. Forms of vitality play is present at a constant rate during the third year of life. Symbolic play flourishes during this period. Combined play patterns are not the most frequent but are present from the beginning to the end of the third year. We suggest that FoVP favours intimate and intersubjective experiences essential to the understanding and the development of the interpersonal world; that it can be thought of as a good runway for the development of symbolic play; and that it prepares the child to participate in the temporal arts that belong to his culture.

Abstract
A quantitative analysis of a trans-generational, conversational corpus of Chintang (Tibeto-Burman) speakers with community-wide bilingualism in Nepali (Indo-European) reveals that children show more code-switching into Nepali than older speakers. This confirms earlier proposals in the literature that code-switching in bilingual children decreases when they gain proficiency in their dominant language, especially in vocabulary. Contradicting expectations from other studies, our corpus data also reveal that for adults, multi-word insertions of Nepali into Chintang are just as likely to undergo full syntactic integration as single-word insertions. Speakers of younger generations show less syntactic integration. We propose that this reflects a change between generations, from strongly asymmetrical, Chintang-dominated bilingualism in older generations to more balanced bilingualism where Chintang and Nepali operate as clearly separate systems in younger generations. This change is likely to have been triggered by the increase of Nepali presence over the past few decades.
