Using assistive technology software to compensate for writing and reading impairments in aphasia
Background: Aphasia is a language impairment affecting approximately one third of people after stroke. It can disrupt speaking, comprehension, reading and writing. This thesis concerned people with aphasia (PWA) with spelling and writing impairments (some also had reading difficulties) but relatively preserved speech and comprehension.
Aims:
1. Consider the evidence for writing treatment interventions with a systematic review of the literature;
2. Conduct a pilot study testing the acceptability of a compensatory narrative writing treatment intervention using assistive technology (AT) software;
3. Report an empirical study which designed, delivered and evaluated a program to train ten PWA to operate two mainstream AT packages (Dragon NaturallySpeaking™, a voice recognition software (VRS) to support writing via dictation, and ClaroRead™, supporting reading via auditory processing). The study tested whether: a) AT could be used to produce functional narrative writing, b) reading support promoted writing success c) the intervention could be customised to suit individual goals.
Methods:
1. Systematic literature review
Electronic databases were searched; 53 papers meeting inclusion criteria were identified. Data were extracted, papers were critically appraised and their findings described.
2. Pilot
Ten week AT training with two PWA to test acceptability of the intervention, design training schedule and materials, and test quantitative assessments and qualitative data collection methods for the main study
3. Main study
Design and setting: Small group study with mixed methods, repeated measures design. Assessments and AT training in participants’ homes or at City, University of London.
Participants: Ten participants meeting eligibility criteria (over 18 years old, medically stable, no significant cognitive impairment, aphasia due to stroke, presenting with acquired dysgraphia) were recruited via convenience sampling. They were not receiving speech and language therapy, had no marked evidence of neuromuscular, structural or motor-speech impairments, nor self-reported history of developmental dyslexia.
Measures and procedure. Participants received 7-10 one-hour individual training sessions. Screening (language, cognition) and diagnostic (single word writing, single word reading) assessments took place at T1 (first baseline). Outcome measures (narrative writing, reading comprehension, quality of life, mood) were taken at T1 and repeated at T2 (second baseline), T3 (end of intervention) and T4 (three month follow up). Participant observation occurred throughout training; qualitative semi-structured interviews, a social participation assessment and cognitive monitoring took place at T2, T3 and T4.
Results:
1. Systematic literature review
Writing treatments were effective but often focused on single word production and seldom tested functional generalisation. Most were single case or small case series studies with remediatory goals; few used qualitative methodologies or investigated the impact of reading deficits. All narrative writing therapies were delivered via technology.
2. Pilot
The intervention was acceptable to participants. Training schedule and materials were created and refined; quantitative outcome measures were finalised; emphasis on participant observation was increased.
3. Main study: Keyboard narrative writing was significantly improved by AT (Friedman’s χ² (3) = 8.27, p = .041), as was keyboard reading comprehension (Friedman’s χ² (3) = 21.07, p < .001), indicating compensatory effects of both AT. There was no change over time in pen and paper assessments of writing or reading, indicating no remediatory effect. A wide range of written genres were produced. Social network size significantly increased. There were no significant changes in mood or quality of life. Individual success rates varied; diagnostic and observation data suggested contributing factors were attitude, creativity, preserved speech production skills, spectrum of other aphasic traits, therapeutic goals, and cognition.
Conclusion: The compensatory customisable AT training was acceptable to eight of ten participants, and resulted in significantly improved narrative writing performance.
Implications: Compensatory AT interventions serve as a useful adjunct to remediatory spelling interventions, and are particularly useful for supporting functional narrative writing
Auditory comprehension: from the voice up to the single word level
Auditory comprehension, the ability to understand spoken language, consists of a
number of different auditory processing skills. In the five studies presented in this
thesis I investigated both intact and impaired auditory comprehension at different
levels: voice versus phoneme perception, as well as single word auditory
comprehension in terms of phonemic and semantic content.
In the first study, using sounds from different continua of ‘male’-/pæ/ to ‘female’-/tæ/
and ‘male’-/tæ/ to ‘female’-/pæ/, healthy participants (n=18) showed that phonemes
are categorised faster than voice, in contradistinction with the common hypothesis that
voice information is stripped away (or normalised) to access phonemic content.
Furthermore, reverse correlation analysis suggests that gender and phoneme are
processed on the basis of different perceptual representations. A follow-up study (same
paradigm) in stroke patients (n=25, right or left hemispheric brain lesions, both with
and without aphasia) showed that lesions of the right frontal cortex (likely ventral
inferior frontal gyrus) leads to systematic voice perception deficits while left
hemispheric lesions can elicit both voice and phoneme deficits. Together these results
show that phoneme processing is lateralized while voice information processing
requires both hemispheres. Furthermore, this suggests that commencing Speech and
Language Therapy at a low level of acoustic processing/voice perception may be an
appropriate method in the treatment of phoneme perception impairments.
A longitudinal case study (CF) of crossed aphasia (rare acquired communication
impairment secondary to lesion ipsilateral to the dominant hand) is then presented
alongside a mini-review of the literature. Extensive clinical investigation showed that
CF presented with word-finding difficulties related to impaired auditory phonological
analysis, while functional Magnetic Resonance Imaging (fMRI) analyses showed right
hemispheric lateralization of language functions (reading, repetition and verb
generation). These results, together with the co-morbidity analysis from the mini-review,
suggest that crossed aphasia can be explained by developmental disorders
which cause partial right lateralization shift of language processes. Interestingly, in CF
this process did not affect voice lateralization and information processing, suggesting
partial segregation of voice and speech processing.
In the last two studies, auditory comprehension was examined at the single word level
using a word-picture matching task with congruent (correct target) and incongruent
(semantic, phonological and unrelated foils) conditions. fMRI in healthy participants
(n=16) revealed a key role of the pars triangularis (phonological processing), the left
angular gyrus (semantic incongruency) and the left precuneus (semantic relatedness)
in this task – regions typically associated via the arcuate fasciculus and often impaired
in aphasia. Further investigation of stroke patients on the same task (n=15) suggested
that the connections between the angular gyrus and the pars triangularis serve a
fundamental role in semantic processing. The quality of a published word-picture
matching task was also investigated, with results questioning the clinical relevance of
this task as an assessment tool.
Finally, a pilot study looking at the effect of a computer-assisted auditory
comprehension therapy (React2©) in 6 stroke patients (vs. 6 healthy controls and 6
stroke patients without therapy) is presented. Results show that the more therapy
patients carry out the more improvement is seen in the semantic processing of single
nouns. However, these results need to be reproduced on a larger scale in order to
generalise any outcomes.
Overall, the findings from these studies present new insight into, as well as extending
on, current cognitive and neuroanatomical models of voice perception, speech
perception and single word auditory comprehension. A combinatorial approach to
cognitive and neuroanatomical models is proposed in order to further research, and
thus improve clinical care, into impaired auditory comprehension
Learning Disabilities
Learning disabilities are a heterogeneous group of disorders characterized by failure to acquire, retrieve, and use information competently. These disorders have a multifactorial aetiology and are most common and severe in children, especially when comorbid with other chronic health conditions. This book provides current and comprehensive information about learning disorders, including information on neurobiology, assessment, clinical features, and treatment. Chapters cover such topics as historical research and hypotheses of learning disorders, neuropsychological assessment and counselling, characteristics of specific disorders such as autism and ADHD, evidence-based treatment strategies and assistive technologies, and much more
Advances in Primary Progressive Aphasia
Primary progressive aphasia is a clinical syndrome that includes a group of neurodegenerative disorders characterized by progressive language impairment. Our knowledge about this disorder has evolved significantly in recent years. Notably, correlations between clinical findings and pathology have improved, and main clinical, neuroimaging, and genetic features have been described. Furthermore, primary progressive aphasia is a good model for the study of brain–behavior relationships, and has contributed to the knowledge of the neural basis of language functioning. However, there are many open questions remaining. For instance, classification into three variants (non-fluent, semantic, and logopenic) is under debate; further data about epidemiology and natural history of the diseases are needed; and, as in other neurodegenerative disorders, successful therapies are lacking. The Guest Editors expect that this book can be very useful for scholars
Testing a Structural Equation Model of Language-based Cognitive Fitness
The normative development of language is often taken for granted, yet problems with language development can result in stress for the individual and family. A challenge with these language development problems lies within the contemporary education system, which assumes that children have appropriate skills when they begin school. The purpose of the study was to test a theoretical model of language readiness known as language-based cognitive fitness, which includes measures associated with structural concepts of language involving receptive language, expressive language, spontaneous narrative speech, and writing fluency. The sample included children from a private school who received an extensive battery of tests at admission and annually thereafter. Scores from a variety of cognitive measures were used in a structural equation modeling framework to test the model. Results demonstrated language-based cognitive fitness to be an interplay of verbal reasoning abilities, visual synthesis, and active analysis broadly representing receptive language, expressive language, spontaneous narrative expression, and writing fluency. Verbal reasoning, visual synthesis, and active analysis explained 91% of the variance in achievement. Implications for positive social change include an improved understanding for those who work with children\u27s language development, specifically of the language structures responsible for language deficits and how these relate to overall cognitive fitness; interventions can be provided to help children more quickly make up language deficits
Supporting a Foundation Phase learner presenting with specific learning difficulties in building resilience : A transdisciplinary approach
Abstract : Inclusive Education departs from the notion that diversity and uniqueness in learners should be supported holistically. Literature, however, points to the challenges that support and its support structures within an inclusive environment face. One such challenge which is the focus of this study, is how learners presenting with various disabilities, in this case particularly Specific Learning Difficulties (SpLD), are integrated and included with learners who do not face the same challenges in the same mainstream classroom environment and show signs of developing resilience despite the challenges their specific learning difficulties present. Research further suggests an eco-systems approach as an attempt to gain deeper insight into the term resilience by considering the resources in the learner’s immediate environments. Research from different fields point to the value of the early childhood phase as a crucial phase in establishing a lifelong foundation for learning, fraught with challenges such as SpLD. Detection and prevention of possible SpLD in learners during this crucial time-period of their developmental process, is thus vital. Literature proposes for these resources to be strengthened and that the implementation of a transdisciplinary approach may be feasible as this approach requires of members from various disciplines to share their roles in supporting learners presenting with SpLD. The transdisciplinary approach is regarded as family-centred and invites parents, care-givers, guardians to collaborate with other role-players in putting necessary interventions in place, taking the entire ecosystem of the development of the learner and its ability to bounce back from setbacks into consideration. The purpose of this study was to explore and describe how a transdisciplinary approach supported a Foundation Phase learner presenting with SpLD, in building resilience within an inclusive learning environment by eliciting relevant school staff, internal therapists and parents/caregivers/guardians’ opinion on how the transdisciplinary approach was implemented; and how the identified learner benefited from its implementation. A qualitative case study design was implemented which included purposively selected participants in accordance with the aim of the study. Data was collected through individual and focus-group interviews. Collected data was analysed through thematic content analysis. xii Findings revealed that the identified learner was not the only one who benefited from the implementation of the transdisciplinary approach but the manner in which it was implemented brought about various enablers for team members to support him and build his resilience. Enablers for team members included supportive communication; collaborative sharing; team-member involvement (as especially from his mother) and trust as well as commitment. Enablers for the learner comprised strong relationships; structure; a sense of control and motivation. In addition to these enablers, findings revealed that this particular remedial school also experienced some challenges in the implementation of the transdisciplinary approach such as time- constraints and impractical suggestions for classroom interventions. Findings also indicated possible challenges that may hinder the successful implementation of a transdisciplinary approach within a mainstream environment such as lack of finances; large class sizes and overwhelmed teachers; uninvolved parents and unnoticed learning challenges.M.Ed.

El acceso y uso de métodos, herramientas y habilidades específicas que los educadores generales de Educación Secundaria griegos tienen para el proceso de enseñanza-aprendizaje del alumnado con necesidades educativas especiales
The modern school, called to operate according to the principles of inclusive education
by including students with special educational needs, forms new training needs for
teachers. In this paper, the opinions and educational needs of the Secondary Education
teachers of the Kavala region are investigated regarding the inclusion of students with
special educational needs in the general school. To implement the research, the mixed
approach was used, i.e. a combination of quantitative and qualitative research methods.
The sample of the quantitative research consisted of 339 teachers who filled out a
questionnaire while the data collected were processed and analyzed with descriptive and
inductive statistics. The sample of the qualitative research consisted of directors of
secondary schools who gave an interview giving their experiences.
Among the most important results of the study is the positive opinion of the majority of
teachers regarding the inclusion of students with special educational needs in the
general school. In addition, the necessity of training, and indeed with a mandatory nature,
of all teachers in the field of Special Education is evident, while their insufficient
preparation during their undergraduate studies in the relevant field is highlighted.
Regarding the content of the training programs, the teachers wish to be trained primarily
in behavioral problems and in the thematic section "Management of students with special
educational needs in the general school". In addition, in-school training and distance
training using new technologies are equally preferred, while the training is chosen to be
conducted within school hours and before the start or after the end of the school year.
Furthermore, teachers mainly choose experiential educational techniques. Finally, the
primary motivation for participating in Special Education training programs is the
connection between theory and practice.
The conclusions drawn from the findings of this research can be used in the planning
and organization of training programs for secondary school teachers in the field of special
educational needs.La escuela moderna, llamada a funcionar según los principios de la educación
inclusiva al incluir a los alumnos con necesidades educativas especiales, configura
nuevas necesidades de formación para los docentes. En este artículo, se investigan las
opiniones y necesidades educativas de los profesores de Educación Secundaria de la
región de Kavala con respecto a la inclusión de estudiantes con necesidades educativas
especiales en la escuela general. Para implementar la investigación, se utilizó el
enfoque mixto, es decir, una combinación de métodos de investigación cuantitativos y
cualitativos. La muestra de la investigación cuantitativa estuvo conformada por 339
docentes quienes llenaron un cuestionario mientras que los datos recolectados fueron
procesados y analizados con estadística descriptiva e inductiva. La muestra de la
investigación cualitativa estuvo conformada por directores de escuelas secundarias
quienes dieron una entrevista relatando sus experiencias.
Entre los resultados más importantes del estudio se encuentra la opinión positiva
de la mayoría de los docentes respecto a la inclusión de los alumnos con necesidades
educativas especiales en la escuela general. Además, se evidencia la necesidad de
formación, y de hecho con carácter obligatorio, de todos los docentes en el campo de la
Educación Especial, al tiempo que se destaca su insuficiente preparación durante sus
estudios de pregrado en el campo correspondiente. En cuanto al contenido de los
programas de formación, los docentes desean formarse principalmente en problemas
de conducta y en el apartado temático “Gestión de alumnos con necesidades educativas
especiales en la escuela general”. Además, se prefiere igualmente la formación
presencial y la formación a distancia utilizando las nuevas tecnologías, eligiendo que la
formación se realice dentro del horario lectivo y antes del inicio o después de la
finalización del curso escolar. Además, los profesores eligen principalmente técnicas
educativas experienciales. Finalmente, la principal motivación para participar en los
programas de formación de Educación Especial es la conexión entre la teoría y la
práctica.
Las conclusiones extraídas de los resultados de esta investigación pueden
utilizarse en la planificación y organización de programas de formación para profesores
de secundaria en el campo de las necesidades educativas especiales
Analisi della scrittura in corsivo durante l'apprendimento e l'influenza dell'et\ue0, del genere e della lingua madre
Le difficolt\ue0 nella scrittura rappresentano una causa comune di scarso rendimento scolastico e di bassa autostima. Oggigiorno, questo problema \ue8 particolarmente importante a causa dell\u2019utilizzo sempre pi\uf9 intensivo delle tecnologie moderne nella vita quotidiana e nelle scuole. Sin dalle scuole elementari, infatti, i bambini stanno incrementando l\u2019uso di tablet e dita a discapito dei classici fogli e penna, rendendo sempre pi\uf9 difficoltoso l\u2019apprendimento del corsivo.
In questo contesto, l\u2019analisi della grafia rappresenta un importante strumento per la valutazione di metodi di insegnamento al fine di esaminarne l\u2019efficacia nella prevenzione della disgrafia. Scopo della presente tesi \ue8 stato quello di analizzare i parametri qualitativi e quantitativi estratti da scritture acquisite mediante tavoletta digitale, al fine di valutare le differenze nell\u2019apprendimento del corsivo in relazione al metodo di insegnamento applicato. In particolare, \ue8 stata eseguita un\u2019analisi comparativa tra il metodo tradizionale di insegnamento del corsivo ed il metodo Terzi esaminando le grafie di 40 bambini, seguiti dalla prima alla quinta elementare, in due classi parallele nelle quali sono stati applicati i due metodi. Gli strumenti di analisi sviluppati hanno permesso di evidenziare le caratteristiche quantitative e qualitative delle grafie e la loro relazione con la scolarizzazione e col metodo di insegnamento seguito.
L\u2019approccio metodologico sviluppato si \ue8 dimostrato adatto a stimare le abilit\ue0 di scrittura e promettente ai fini dell\u2019identificazione precoce della disgrafia nell\u2019infanzia. Inoltre, queste metodologie sono state utilizzate per indagare l\u2019influenza del genere, dell\u2019et\ue0 e della madrelingua sui parametri cinematici della grafia.Handwriting difficulties represent a common cause of underachievement in children education and low self-esteem. Nowadays a new problem arises due to the growing use of modern technologies in daily life and in the school. In fact, primary-school children are increasingly using tablet and fingers rather than classic paper and pencil so that cursive writing is becoming difficult to learn properly and achieve correctly.
In this context, the analysis of handwriting represents an important tool for the evaluation of a teaching method to assess its efficacy in preventing dysgraphia. The aim of this thesis was the qualitative and quantitative analysis of handwriting acquired by using digital tablet in order to assess the differences of achievement of cursive related to different teaching methods. A comparative analysis between the traditional handwriting teaching method and the alternative Terzi's approach in 40 pupils, from the first to the last year of the primary school, was performed. The results highlighted that both quantitative and qualitative features of cursive handwriting depended on the teaching approach.
The developed methodologic approach proved to be a suitable tool for handwriting assessment and for the early identification of dysgraphia. Furthermore, the tool was used to investigate the influence on the kinematic parameters of handwriting by gender, age and mother-tongue
