Speech perception precedes, indexes, and is changed by language acquisition. What is exceptional about human infants is not their sophisticated speech perception (for animals perceive human speech similarly) but their use of speech to regulate linguistic attention and bootstrap language. Using a new validated measure, language specific speech perception (discrimination ability for native minus non-native speech sounds), we can ascertain children's distribution of resources in linguistic tasks.

What is exceptional about human infants is not their sophisticated speech perception (for animals perceive human speech similarly) but their use of speech to regulate linguistic attention and bootstrap language. Using a new validated measure, language specific speech perception (discrimination ability for native minus non-native speech sounds), we can ascertain children's distribution of resources in linguistic tasks. This measure will be used in conjunction with a raft of experimental psycholinguistic techniques to investigate speech perception bases of phoneme perception, tone perception, word meaning, reading, and their vestiges in adulthood, to arrive at a dynamic new conception of language development.

High resolution warm ocean records from laminated sediment. This project will produce environmental records during ocean warming events in the geologic past to reveal processes associated with warm oceans similar to those anticipated in the coming century. New Australian technology allows investigation of sediment records at unprecedented time resolution providing insight into processes operating on societally relevant time scales of decades to centuries. This work will open an archive of climat ....High resolution warm ocean records from laminated sediment. This project will produce environmental records during ocean warming events in the geologic past to reveal processes associated with warm oceans similar to those anticipated in the coming century. New Australian technology allows investigation of sediment records at unprecedented time resolution providing insight into processes operating on societally relevant time scales of decades to centuries. This work will open an archive of climate information revealing feedback, thresholds and tipping points from past events previously inaccessible because of technical and conceptual limitations. It will provide critical inputs into models predicting future climate and to illuminate the risks and compensating feedbacks occurring with warming.
