It was about one and a half years ago that I finally I arrived where I had always wanted to be and do what I had always wanted-- teach students, support small language communities and conduct research on African languages on my doorstep. The University of Cape Town and my new colleagues welcomed my efforts to establish the Centre for African Language Diversity-- CALDi as well as The African Language Archive-- TALA and I was recently appointed the Mellon Research Chair: African Language Diversity this initiative. The main aim of CALDi is to train young African scholars in descriptive linguistics and open up space for research into African languages at UCT with the hopes of countering the dominance of African linguistics outside the continent. It has been a great challenge for which my whole career has been a form of preparation...Read more
The Cambridge Handbook of Communication Disorders examines the full range of developmental and acquired communication disorders and provides the most up-to-date and comprehensive guide to the epidemiology, aetiology and clinical features of these disorders.
Children often listen to speech in noisy environments, where they must use prior knowledge to help them interpret the intended signal. The present experiment compares school-aged children's and adults' use of one such form of prior knowledge, as demonstrated in the perceptual restoration effect. Children, like adults, perform better when speech is intermittently replaced with noise than when it is replaced with silence, suggesting that children are able to make use of prior knowledge to help them restore interrupted signals. Despite this fact, children appear to be more affected by acoustic signal disruptions than are adult listeners, suggesting they will experience greater difficulty in noisy environments.
