The Child Language Lab studies the process of early child language acquisition, focusing especially on phonology and morpho-syntax. This includes studies of children acquiring Australian English as their native language as well children being raised bilingually, early child second language acquisition, children with hearing loss,  and children with language delay (SLI). 

Lab Director Katherine Demuth elected as new Fellow of the Academy of the Social Sciences of Australia

Distinguished Professor Katherine Demuth ASSA Fellow

Congratulations to lab director, Distinguished Professor Katherine Demuth, who was announced this week as a new Fellow of the Academy of the Social Sciences in Australia. Katherine Demuth, a world leader in linguistic research, is passionate about the importance of theoretically driven empirical evidence for understanding both the structure of languages and how children learn them. This is evidenced in her ground breaking psycholinguistic research on child language acquisition, and the implications this has for understanding language development in bilinguals, those with hearing loss, and those with specific language impairment/language delay. Professor Demuth's professional values align strongly with those of the Academy, and she is honoured to be joining others as a newly elected Fellow.
