A number of studies have reported that many children with Autism Spectrum Condition (ASC) experience unusual responses to sensory stimuli, however it is argued that there is a lack of conceptual understanding regarding this phenomenon and an underdeveloped evidence base regarding appropriate support for these responses within an educational context. Despite this, practitioners from a range of professions are called upon to offer consultation, advice and intervention. Therefore, the present study sought to qualitatively explore the experiences of these professionals with regards to the sensory needs of children with ASC within an educational setting. An exploratory single-embedded case study design was adopted. Two Specialist Teachers, two Educational Psychologists (specialists in ASC) and two Occupational Therapists were recruited opportunistically and individual semi-structured interviews were conducted with each participant, resulting in six interviews. Each interview was audio recorded and transcribed verbatim. Interview data were analysed using thematic analysis and the findings presented as three thematic maps according to research question. Six organising themes were identified for Research Question 1: conceptualisations, assessment, defining unusual sensory responses, pragmatism, impact at school and professionals’ roles. Three organising themes arose from the data for Research Question 2: interventions, differences between special and mainstream, and efficacy. The data from the interviews yielded two organising themes for Research Question 3: barriers and facilitators. The study extends conceptual understanding by presenting a proposed Interactive Factors Framework (IFF) for unusual sensory responses in children with ASC. A number of recommendations for supporting children with ASC and unusual sensory responses within educational settings are also proposed. Implications for professionals supporting the sensory needs of children with ASC are discussed with reference to the pragmatic issues involved in translating a developing evidence base into practice.

Children with Autism Spectrum Disorders (ASD) have deficits in communication and delays in language development, but there have been few studies of their vocabulary. This study compared longitudinal parent report data from the MCDI collected for 49 children with ASD over three years with data from the MCDI norms. It focused on three aspects of lexical development: (1) change in lexical composition as evident in percentage of predicates/nominals; (2) order of emergence for predicate types and (3) predictive value of lexical variables for later grammatical development. ASD Groups were matched to typically developing group norms on total MCDI scores for each comparison. Subsequent analysis indicated: (1) no differences in the percentages of predicates/nominals for the two groups at 3 time points; and, (2) virtually identical orders of emergence for different predicate types with the exception of three meaning type categories—quantitative predicates, cognitive/affective predicates and predicates involving causal acts to change experiential states. Cognitive/affective predicates were found to come in somewhat later in ASD groups while quantitative predicates and predicates involving changes in experiential states came in earlier in ASD groups. This study also found (3) that lexical variables, especially number of predicates, strongly predicted grammatical complexity one year later, a process common in typical language development. The study concludes that lexical development in ASD follows the normal course, albeit later and more slowly. It also suggests that communication deficits in this population are rooted in challenges with social acts rather than from an inability to match meanings to words. / Medicine, Faculty of / Audiology and Speech Sciences, School of / Graduate

Heightened levels of stress are observed in mothers of children with autism spectrum disorders (ASD), yet little is known about the relationship between stress and coping in mothers of children recently diagnosed with an ASD. The objectives of this study were to determine the levels of maternal stress, identify coping strategies used by mothers, examine the relationship between stress and coping, and ascertain whether coping mediated the relationship between ASD symptom severity and subsequent maternal stress. Data on 128 mothers of children who had received a diagnosis of ASD in the last four months were examined. Results indicated that mothers presented with elevated levels of stress. With regards to coping, escape-avoidance and confrontive coping were positively correlated with stress, while seeking social support was negatively correlated with stress. Confrontive coping did not mediate the relationship between ASD symptom severity and maternal stress. Results confirm previous findings, while underscoring the importance of helping mothers understand the relationship between the coping strategies they adopt and the subsequent stress they experience.

Siblings of children who have been diagnosed with autism can play important roles in the lives of their brothers or sisters. Previous literature shows that siblings can effectively change behavior and can increase play interactions. Furthermore, the use of preferred materials may enhance social interactions between the siblings. The purpose of this study was to determine, the effects that material preferences and choices have on sibling social bids and cooperative play during a sibling training program. There were two main objectives. The first objective was to evaluate the effects of teaching with the high preference toy of the neuro-typical sibling during sibling training. The second objective was to determine if the training would produce different effects across four different toy conditions. Measures included social bids made by each of the siblings and cooperative play. Results indicate that teaching with the neuro-typical siblings' high preference toy during sibling training can be an effective method to increase social bids and cooperative play. The results of this study are discussed in the contexts of preference and choice selections, physical environments, motor skills, carry over effects, and participations based on gender.

Previous research has shown that early and intensive behavioral interventions are an effective treatment for young children with autism resulting meaningful gains that can maintain over time. For behavioral treatments to be effective, service providers need to be competently trained in behavioral interventions through staff training. The purpose of the current study was to replicate and extend previous research by employing a more rigorous research design, and including measures of teaching units, and staff and child affect measures. The trainee was taught 150 skills. Training methods included descriptions, modeling, practice, and feedback. Results showed that the trainee acquired all skills while maintaining an increasing number of teaching units. Child and staff also maintained favorable affect as training progressed. In addition, staff reported the training as very effective and highly satisfactory. This shows that comprehensive training packages that comprise a large set of skills in real life treatment settings can result in benefits for the staff and children.

Children diagnosed with autism exhibit deficits in communication that impact their ability to control their immediate environment. Recent research on mand training has been criticized for producing a limited number of mand topographies over a long span of time with limited generalization to novel environments. There is a body of research, however, that successfully establishes larger repertoires. Training parents as change agents may mediate generalization by teaching under naturally maintaining contingencies. Additional effects of parent training may reduce parent reports of stress, increase favorable quality of parent-child interactions, and increase reports of parental self-efficacy. The current study evaluated the effects of a generalized training framework to teach parents how to target generalized mands and expand their child’s communicative topographies. The effects of the training were evaluated using a non-concurrent multiple baseline across participants and skills. Results indicated that parents were able to effectively teach their child to mand for a variety of items and events and to substantially increase the number of different mand topographies and expand the topographies the child emitted. Parents were observed to have higher overall confidence and lower overall stress following intervention. The current study builds on previous research on generalized teaching strategies for parents that are effective in teaching a variety of responses to the child.

Clinically significant motor impairment affects 50-100% of those with Autism Spectrum Disorder (ASD). Although not included in the diagnostic criteria, research suggests that motor impairments appear during infancy, precipitate the onset and progression of classical autistic symptomology, and are associated with the severity of autist deficits. Presently, few studies directly address motor impairment in ASD. In those that do, physical education, exercise, and exergaming interventions have been found to enhance motor skill proficiency. Little is known about the effect of unstructured physical activity on motor skills in children with autism. Thus, this pilot study sought to examine the impact of unstructured, one-on-one, physically active play on motor skill proficiency as defined by the Test of Gross Motor Development-2 (TGMD-2) in autistic children between ages 3 and 10. Twenty, one-on-one, 60-minute play-based physical activity sessions were administered over a 10-week period (2x/week). The physical activity environment was arranged according to the North Carolina Treatment and Education of Autistic and Related Communications Handicapped Children (TEACCH) guidelines. Session structure precluded skill teaching and sought to elicit gross and fine motor activity within physical activity opportunity stations, but without regard to type or intensity of activity. A comparison of pre-and post-intervention TGMD-2 scores captured motor skill outcomes. Findings suggest that unstructured physically active play is not sufficient to improve global motor skill competency in young children with autism. However, active play fostered significant improvements in two in running skill scores. The TGMD-2 is designed to assess those skills that would foster participation in physical education and recreational settings. Improved running may advance play-abilities and support other forms of activity. Future research should consider using assessments more sensitive to acute changes in motor skill efficacy, measurement of time spent in physically active play, and qualitative analysis of parent-perceived outcome and improvement.

I detta arbete undersöks teorin att flickor diagnostiseras senare än pojkar, och vad detta möjligen har för konsekvenser på fritidshemmet, både för personal, övriga elever och de elever med autism. Varför och vilka möjliga skillnader det finns som kan påverka diagnostiseringen för flickor. Syftet med arbetet är att besvara följande frågeställningar; • Hur visar sig diagnosen autism hos flickor? • Finns det skillnader i diagnosen mellan flickor och pojkar? • Vilka konsekvenser får detta för flickorna på fritidshemmet? Arbetet beskriver vidare om vilka konsekvenserna blir på fritidshemmet både för fritidshemmet och eleven själv. Resultatet visar att flickor med autism på fritidshem är ett område som tidigare inte är utforskat i större utsträckning. För att besvara dessa frågeställningar har pedagoger med erfarenhet deltagit i vår undersökning, som arbetar i skolverksamhet och personer med erfarenhet av flickor med autism utöver skolverksamhet. En del av de informanter som deltog kände att de inte hade tillräckligt med kunskap om flickor med autism, och/eller flickor med autism på fritidshemmet. Resultatet visar även att flickor med autism som inte får stöd riskerar utveckla psykisk ohälsa som exempelvis ångest och depression.

The high prevalence of autism spectrum disorder (ASD) results in large costs to individuals, families, and society. Among diagnosed individuals, restrictive and repetitive behaviors (RRBs) correlate with functional impairments substantially impacting wellbeing but remain less studied than social and communication deficits. Brain resting-state functional connectivity (fc) measures intrinsic, potentially RRB-associated neural dynamics. Here, whole-brain (WB), and iterated seed-based (SB)fc guided by the preceding WBfc and a priori hypotheses was performed. Combined results were used to model a brain network beginning with qualitative assessment of its potential functional association with RRBs. Once rigorously defined, the network was used to inform construction of a dynamical systems model of brain activity hypothesized to correlate with RRB severity. Qualitative model behavior tracked expectations of real cortical activity in RRB presentation. Model numerical output was found to correlate with behavioral measures of RRBs to a significantly greater degree than the underlying brain connectivity values themselves did. Some summary measures of model output were also found to correlate significantly, though near threshold, with severity measures in the other two ASD core deficit domains, and particularly, far more extensively than should be expected given the underlying brain connectivity values themselves were apparently effectively wholly uncorrelated with the measures. Significant findings are: (1) dynamical modeling of brain activity can identify significant correlations with symptom manifestation that fc alone cannot; (2) dynamical modeling of brain activity could potentially increase understanding of ASD’s extensive heterogeneity across symptom domains; (3) extensive overlap between the constructed network and known RRB-implicated brain divisions was identified, with cerebellum, increasingly implicated in distributed neocortical functional differences in RRBs in humans and animal models, centrally connected to multiple such divisions; (4) further overlap is found via striatal circuitry, implicated in multiple RRB-like behaviors previously, and forming at least 1/3 of the functional basis for the network’s hypothetical relationship with RRBs; (5) ASD-associated angular gyrus, PFC, ACC overlap was found. This successful tandem application of fc, dynamical modeling, and neurocognitive network theory illustrates the need for broad theoretical approaches in illuminating ASD heterogeneity and the neurocognitive underpinnings of specific ASD presentations. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2021. / FAU Electronic Theses and Dissertations Collection

This study analyzes the experiences of stigmatization and emotion work through the interview responses of eight parents of children with autism. Developing from Goffman’s theories of direct stigma and associative stigma this research integrates Hochschild’s emotion work as a way that parents respond to the stigmatization that they encounter. The results of this study indicate that some parents of children with autism perform suppressive emotion work in the way they respond to stigmatization and obstacles that occur when raising a child with special needs. In addition, stigma occurs in interactions with close friends and family members, creating issues of boundary-crossing. Parents of children with autism respond to stigma by educating those closest to them and normalizing the experiences of themselves and their child. In order to cope with the hardships of stigma, some parents also work to advocate, problem-solve, and build community beyond their immediate relationships.
