Prof Alan Rumsey

Australian National University
Chief Investigator and Project Head

Alan Rumsey is an Emeritus Professor of Anthropology at Australian National University. His research focuses on relationships between language and other aspects of culture and social life, based on fieldwork in the Kimberley region of Western Australia and the Ku Waru region in the Western Highlands of Papua New Guinea. Since 2013 he and Francesca Merlan have been studying Ku Waru children’s language socialisation. In this project they build on that work through the study of the interplay between speech and other bodily modes of communication. The new research will be based on their existing transcribed video recordings of interactions involving children between the ages of two and five, and also on new fieldwork focusing on interactions involving infants.

Lourdes de León is Professor of Linguistics and Anthropology at the Centro de Investigaciones y Estudios Superiores en Antropología Social in Mexico. Most of her research focuses on community learning, first language acquisition, and language socialization of the Mayan language Tzotzi, encompassing all stages of life. She conducts field research among the Tzotzil Mayan people in the highlands of Chiapas and other indigenous regions of Mexico. In the BLS project, she will investigate multimodal aspects of language socialisation based on ordinary interactions involving Tzotzil children.

Prof John Haviland

University of California, San Diego
Partner Investigator

John Haviland, UCSD Anthropology, studies the social life of languages including Tzotzil (Mayan), Paman languages in Australia, and a first generation sign language in Chiapas.  His publications include several grammatical sketches, and range over topics from gossip in Zinacantán, the demise of a language (and its last speaker) in Queensland, and the (dis)honorifics of avoidance languages, to gesture, and the emergence of grammar and language ideology. His research in this project investigates coexpressive modalities in the emerging sociolinguistic skills of young children who speak Tzotzil, sometimes while mastering an emerging sign language in their household, and those of a pair of twin children growing up trilingually (in English, Italian, and Spanish) over the first 4 years of their lives.

Prof Elinor Ochs

University of California, Los Angeles
Partner Investigator

Elinor Ochs is Distinguished Research Professor at the University of California, Los Angeles. Through ethnographic fieldwork conducted in diverse locations including Madagascar, Western Samoa, Italy, and the United States, she explores how linguistic and cultural practices shape human life. Her interdisciplinary research lies at the intersection of linguistics, anthropology, and psychology. Through her work on children–caregiver interactions in Samoa, as well as her collaborative work with Bambi B. Schieffelin, she co-developed language socialization as a field of enquiry. In the current project, she explores how the home life of families is shaped multimodally through culturally and situationally organised social interactions such as family dinners.

A/Prof Tamar Kremer-Sadlik

University of California, Los Angeles
Informal Participant

Tamar Kremer-Sadlik researches the dynamics of family life, focusing on how socio-cultural beliefs shape family relationships and everyday routines. Her work explores the interplay between local cultural perspectives on family, work, childhood, parenting, and ethics, and how these influence the daily experiences of family members. By drawing on an interdisciplinary approach, including linguistic and psychological anthropology, sociology, and psychology, she investigates the impact of cultural norms and preferences embedded in institutional policies and public discourse on child-rearing, time allocation, social engagement, and family decision-making. In this project, she will investigate food-sharing practices and interaction during family dinners.

Prof Marjorie Harness Goodwin

University of California, Los Angeles
Informal Participant

Marjorie Harness Goodwin is a Distinguished Research Professor at the University of California, Los Angeles. Much of her research focuses on the lived and embodied practices through which human beings construct their social, cultural and cognitive worlds. She investigates how children in peer groups across various US settings and social classes elaborate and dispute their notions of moral behavior as they play together on the street and on the playground, looking at gossip, games, and forms of social exclusion. Her work with middle class American families investigates how family members use touch, gesture, and prosody in conjunction with talk to establish, maintain, and negotiate intimate social relationships, orchestrate activities through directives, and engage in playful explorations of the world.

DR Sara Ciesielski

Informal Participant


Sara Ciesielski completed her PhD at the University of Melbourne, focusing on how children in the Solu-Khumbu region of Nepal learn the Sherpa language and culture. Her child-centered approach provides an account of children’s development of culture through language that is sensitive to children’s individual differences and culturally shaped patterns of interaction. In the BLS project, she will investigate multimodal aspects of Sherpa language socialisation: the ways that body position, movement, and gesture flow into directives from caregivers to children and from children to caregivers.
