Elderly speech perception in noise. This project adopts an innovative approach to understand problems that elderly people have in recognising speech in noise. Using a detailed computational (glimpsing) model, measures of auditory and visual information and novel priming methods, the project aims to determine precisely what processing is carried out in the early stages of perception. Quantifying and systematically varying input information and measuring perceptual processing are essential for pi ....Elderly speech perception in noise. This project adopts an innovative approach to understand problems that elderly people have in recognising speech in noise. Using a detailed computational (glimpsing) model, measures of auditory and visual information and novel priming methods, the project aims to determine precisely what processing is carried out in the early stages of perception. Quantifying and systematically varying input information and measuring perceptual processing are essential for pinpointing where speech perception problems arise and provide a foundation for evaluating remediation and training. This research aims to contribute to theories of speech recognition and has practical application for speech assessment.Read moreRead less
Attention please! Selective attention and human associative learning. Selective attention allows us to pick useful pieces of information out of the mass of stimulation that we're faced with every moment. This project investigates how what we've previously learnt about the significance of events influences whether we'll pick them out as useful in future, and how this might be impaired by old age or mental disorder.
Speech production in the developing brain. This project aims to study how children acquire language. Speech is arguably the most complicated action that humans can perform, yet is acquired with apparent ease in the pre-school years. The brain mechanisms of speech production have rarely been studied in children due to methodological and technical challenges. This project will address this gap using an articulographic setup for measuring speech movements concurrently with scanning of brain activit ....Speech production in the developing brain. This project aims to study how children acquire language. Speech is arguably the most complicated action that humans can perform, yet is acquired with apparent ease in the pre-school years. The brain mechanisms of speech production have rarely been studied in children due to methodological and technical challenges. This project will address this gap using an articulographic setup for measuring speech movements concurrently with scanning of brain activity in a customised paediatric brain imaging system. The results are expected to help explain why most children acquire speech easily and smoothly and why this process can be more difficult for others.Read moreRead less
Investigating the characteristics of older adults' conversation behaviour. The project aims to determine the factors that negatively impact older adults’ ability to engage in conversation. This is an important health issue; conversations are essential for communicating needs and maintaining social links; reduced social engagement leads to serious health problems and anticipates cognitive decline. The project will compile profiles of older adults' auditory-visual conversation behavior and indices ....Investigating the characteristics of older adults' conversation behaviour. The project aims to determine the factors that negatively impact older adults’ ability to engage in conversation. This is an important health issue; conversations are essential for communicating needs and maintaining social links; reduced social engagement leads to serious health problems and anticipates cognitive decline. The project will compile profiles of older adults' auditory-visual conversation behavior and indices of perceptual, cognitive and social skills. A path model will link these data to ratings of social engagement and satisfaction. By identifying factors leading to low ranked conversations, evidence-based guidelines can be developed for older adults and their carers to enhance communication and improve health and well-being.Read moreRead less
Comprehending text: A natural laboratory for investigating cognitive ageing. This project aims to determine whether the cognitive processes required for reading comprehension change in old age. Reading is a complex skill that requires precise co-ordination of perception, cognition and attention but appears relatively immune to age-related declines that impair performance in other complex cognitive tasks. Sophisticated eye tracking and electrophysiological studies will be analysed to specify how ....Comprehending text: A natural laboratory for investigating cognitive ageing. This project aims to determine whether the cognitive processes required for reading comprehension change in old age. Reading is a complex skill that requires precise co-ordination of perception, cognition and attention but appears relatively immune to age-related declines that impair performance in other complex cognitive tasks. Sophisticated eye tracking and electrophysiological studies will be analysed to specify how older adults adapt to the sensory and neural impairments associated with age. The outcomes will advance theories of cognitive ageing and reading comprehension and contribute to development of novel interventions to predict and enrich cognitive capacities in old age.Read moreRead less
The seeds of literacy in infancy: empirical specification of the acoustic determinants of language acquisition. Reading is one of the most difficult skills we learn, and while the process is largely forgotten by adults, any minor difficulty can have lasting effects. This project will follow speech, vocabulary and reading in infants at or not at risk for dyslexia from six months to five years with implications for parent-child interaction and language delay intervention.
