Rose’s research is mainly on the syntax of IKalanga and Setswana, both spoken in Botswana. Over the past few years she has extended her research interests to Khoesan languages and she has a few publications based on ǁGana, a Khoesan language from New Xade, Botswana. She also conducts social and ethnological based researches in the areas of language and gender as well as language attitudes. Rose is the Editor of Marang Journal of Language and Literature.

Naledi’s research interests include experimental linguistics, language processing, comprehension and acquisition. More specifically, her work focuses on mental processes that occur during language processing. She does research on English and Setswana, the official and national languages of Botswana.

Naledi sits on the Editorial Board of Marang Journal of Language and Literature, is a Board Member of the African Psycholinguistics Association (APsA), a Language Champion for the Oxford University Press – Setswana Living Dictionary, and is an Alternative Member of the University of Botswana’s Social and Behavioural Institutional Review Board (research ethics committee).

Christina Samuelsson
Professor: Karolinska Institute, Stockholm

Christina has long standing research within language disorders in children, and she has specialised in prosody and phonology. She is also active in the European network on research in child language disorders, EUCLDIS. Currently Christina’s research regards interaction involving people with communicative disabilities. The focus is on describing and facilitating communication for children with language impairment, people with aphasia and people with dementia.

Christina is currently involved in adapting two assessment tools to measure language development in Swedish, Sesotho and Setswana speaking children from 8 to 36 months. The project focuses on linguistic production and gesture development as well as on language comprehension. She is also running a project on early lexical development and development of gestures in children with cochlear implants and children with DLD.

Katie Alcock
DPhil (Experimental Psychology)
Senior Lecturer: Psychology, Lancaster University

Katie’s research interests include language development, the cognitive psychology and neuropsychology of language, and the influence of health and disease on neuropsychological development. Her research experience is in two main areas:

  • What makes children different from each other in learning language? I look at child-originating differences (especially motor control and cognitive abilities) and external-originating differences (including SES and the language that children are learning). Research in this strand includes highly-cited work on motor control and language development, work on developmental language disorders, and construction of Communicative Development Inventories which enable researchers to collect accurate information about children’s language development.
  • What health factors impact on children’s development? Here I look in particular at health factors that are common in developing countries, including malnutrition and parasitic infections, as well as neurological conditions arising from cerebral malaria, and also at the impact of interventions designed to alleviate these factors. Research in this area always has to include the development of cognitive and language tests to assess children’s abilities, and the consideration of the effects of culture and schooling on children’s development.


Michelle White
Postdoctoral Fellow: Center for Multilingualism in Society across the Lifespan, Oslo University

Michelle’s research interests lie in how young children acquire language(s) and what affects this acquisition. Her previous research involved exploring language development in conjunction with working memory and executive function. More Recently, she has become involved in developing parental questionnaires that can be used to assess very young children’s language development, especially when a child is learning more than one language.
