Abstract:
As the title of the thesis indicates, this study intends to investigate the phonological disorders elicited in the speech samples of eight Iraqi children diagnosed with autistic disorders.The purpose of the work is to tackle the field of autism in Iraq by virtue of the shortage of studies in this area, especially in the speech disorders of Iraqi autistic children. The work also aims to contribute to the field of autism within the field of phonology in Iraqi Arabic autistic samples for the first time. The third aim to achieve in this thesis is to capture the most common phonological processes that are noted in the speech samples of the participants using two models. The first model is Clark, Yallop and Fletchers (2007) generative phonological rules, in which an attempt is made to apply the phonological rules to the speech of the autistic. Optimality - theoretical model is also approached to form specific constraint restrictions to allow certain unified representations.Phonemic substitution, elision and assimilation are the most prevalent phonological processes that are observed in the speech of the participants, and they are discussed with their results and conclusions according to both models in the study.The present thesis is comprised of five chapters. The First Chapter displays the preliminaries of the study with the methodology of the experimental design and information about the eight participants as well as how the data is collected and recordings are conducted for them . Chapter Two, then, introduces the literature review of Autism and Autism Spectrum Disorders (ASD) with their symptoms, causes, diagnosis and the most relative cognitive theories. Phonology of Iraqi Arabic (IA) and the most common developmental phonological processes are also matters of concern.All recordings are transcribed using phonemic transcription and disorders are categorized according to the most common ones that are elicited in the speech samples. The work, then, describes and analyzes the three elicited phonological processes using both generative phonological rules and optimality theoretical model in Chapter three and Four. Finally, the general conclusions of the overall work with some recommendations and suggestions for certain needed studies to confirm these findings are presented in Chapter five.ivThe most prominent outcomes of this study are the following : 1 - The linguistic performance of the autistic subjects is phonologically impaired.2 - The most dominant developmental phonological processes elicited in the speech of the subjects are phonemic substitution(60.226%), elision (21.392%) and assimilation (18.380%).3 - Processes that are related to phonemic substitution and elision cover both vocalic and consonantal segments.4 - All consonants are confronted to assimilation, and they are all exhibited either to regressive or progressive assimilation.5 - The data that is collected for this study fits both the generative models that are implemented, i.e. the generative phonological rules and the OT candidate screening model.6 - Concerning the analysis of phonemic substitution and elision via OT model, it is found that a competition occurs between certain faithfulness constraints with regard to both vowels and consonants. Specific faithfulness constraints are also elicited within the OT analysis for assimilation.
