Book Description
Aims: Aims of this doctoral thesis were to 1) investigate the effects of a unilateral hearing loss (UHL) in adults and children examining several auditory abilities such as localising sound, recognising speech in noise and self-perception of hearing disability in daily life contexts due to this condition, 2) measure cortical auditory evoked potentials (CAEPs) elicited by speech sounds to explore the effects of UHL on brain responses, 3) compare group performance between normal hearing controls and the study group for behavioural and electrophysiological measures, 4) examine auditory function over time in a child with single sided deafness who received a cochlear implant and 5) monitor the pattern of change over time in an adult who had a sudden onset of single side deafness after acoustic neuroma removal and to determine the impact of his hearing device use on auditory function. Methods: Auditory skills were assessed using tests of sound localisation, spatial speech perception in noise, and self-ratings of auditory abilities (abbreviated 7-item version of Listening Inventory for Education, LIFE-7 NZ; Speech, Spatial and Qualities of Hearing questionnaire, SSQ; and Auditory Behaviour in Everyday Life, ABEL). CAEPs in noise (+5 dB signal to noise ratio) elicited by consonant-vowel naturally produced speech sounds were recorded. Performance of children and adults with UHL were compared with normal hearing participants' results. Results: Adults and children with UHL had major, statistically significant difficulties compared to controls recognising speech in noise even when the signal was directed to the good ear, with difficulties more evident for children. Sound localisation was affected by UHL for both adults and children, however there was greater variability in children, particularly for the right ear. Adults and children reported higher levels of hearing difficulties in everyday life listening situations compared to controls. Activities which require concentration and attention were reported as the most challenging (indicating high listening effort). Brain responses showed differential changes as a function of the age. Adults with a right ear hearing loss (left ear stimulus presentation, to the better ear) showed a more symmetric hemisphere activity (N1 response) across all stimuli. CAEPs for adults with a left ear hearing loss were similar to normal hearing controls as these participants showed larger activity for electrodes located over the hemisphere contralateral to the stimulated ear (right ear presentation). Normal hearing children showed a left hemisphere dominance (P1 cortical response) regardless of the ear of stimulus presentation, and larger responses at frontal and central locations. Children with UHL did not show this dominance. Overall, for left ear UHL, P1 responses were smaller compared to right ear UHL. N250 responses were larger frontally in normal hearing children, whereas children with left ear UHL had more symmetric CAEP activity. Conclusions: People with UHL have a range of listening difficulties such as localising sound in the horizontal plane and recognising speech in noise. Children and adults and the children's parents reported difficulties in different contexts. Questionnaire data indicated that the ability to recognise speech in different contexts and spatial hearing were perceived as most affected by a UHL for adults. Children reported difficulties in school settings mainly for noisy situations. Participants with UHL reported higher levels of need for concentration or attention during listening activities. CAEPs showed changes within the auditory cortex for children and adults. Atypical responses were observed for both groups compared to normal hearing individuals. CAEPs would be a useful tool for assessing auditory cortical function in people with UHL, providing information about the status of the neural encoding of the auditory signals to support the behavioural evidence for auditory difficulties in this population.

Book Description
Understanding Developmental Disorders of Auditory Processing, Language and Literacy Across Languages Auditory processing disorders, reading and writing disorders, language disorders, and other related disorders - these disorders seem distinct among one another from historical and professional practice perspectives but more and more research suggests that they in fact overlap in many ways including clinical presentations, suspected underlying causes, diagnostic criteria, and re/habilitation strategies. On January 4-7, 2012, the conference Global Conference on Disorders in Auditory Processing, Literacy, Language & Related Sciences (APLL 2012) was held in The Hong Kong Institute of Education. This was the world’s first platform for interdisciplinary discussions and collaborations on ways we can better serve children who suffer from the above closely related disorders through future research. Due to the huge success of APLL2012, to promote continuous discussions of the conference theme, the conference organizing committee decided to invite scholars, scientists, and practitioners to contribute their work to the eleventh volume in the Research on Sociocultural Influences on Motivation and Learning research monograph series. This volume is focused on issues in typical and disordered developments in auditory processing, literacy, and language across different cultural and linguistic contexts in Asia, Europe and North America. The contributors of this volume offer insightful theoretical and practical ideas to shape future directions in research, assessment, intervention, and education. This is an intriguing and inspiring volume for students, researchers, and practitioners in the fields of speech-language pathology, audiology, developmental psychology, educational psychology, neuropsychology, and other related disciplines. By bringing in respective leaders in the fields, we hope that this book will open new windows to promote advancements in related research initiatives, continuing cross disciplinary discussions and collaborations on ways that we can better service individuals suffer from these closely related disorders through future research.

Book Description
This book takes a comprehensive look at the basic principles underlying central auditory processing disorders (CAPD) and the screening, assessment, and management of these disorders in school-age children. It focuses on the practical application of scientific theory in an easy to read, clinically applicable format. It also includes step-by-step assessment tips, normative data, methods of test interpretation, development and implementation of management plans, and integration of central auditory information. Learning and communication profiles are also included to provide a comprehensive picture of CAPD assessment and management.
