Purpose Children with Autism Spectrum Disorder (ASD) show reduced attention to social stimuli. The reasons for these impairments are still being debated by researchers. The aim of this study is to analyse if reduced attention towards social stimuli is determined by initial underlying difficulties in the control of visual attention. Among the variables that could produce these difficulties, the authors considered geometric complexity and typology of geometric figures. Design/methodology/approach To test this hypothesis, in this paper, an eye-tracker paradigm was used for assessing visual exploration and recognition memory towards geometric figures (curved vs rectilinear) with two levels of geometric complexity (low and high) in 17 children with ASD matched with 17 children with typical development (TD). Findings The results showed that the ASD group seemed indifferent to both the geometric complexity and the typology of figures (curved and rectilinear), whereas the TD group showed higher performances with highly complex and curved geometric figures than with low complex and rectilinear geometric figures. Research limitations/implications Because of the chosen research approach, the research results may lack generalizability. Therefore, researchers are encouraged to test the proposed hypotheses further. Practical implications This paper includes implications upon the presence of an unspecified visual attention deficit that is present from the early stages of the processing of stimuli. Social implications The understanding of this deficit from the early stages of the processing of stimuli can help educators to intervene at an early stage when disturbances in social relationships are starting. Originality/value This study contributes to understanding the presence of dysfunctional perceptual antecedents that could determine general difficulties in paying attention to social stimuli in ASD subjects.

AbstractIndividuals with autism spectrum disorder (ASD) have been found to view social scenes differently compared to typically developing (TD) peers, but results can vary depending on context and age. We used eye-tracking in children and adults (age 6–63) to assess allocation of visual attention in a dynamic social orientation paradigm previously used only in younger children. The ASD group (n = 94) looked less at the actor’s face compared to TD (n = 38) when they were engaged in activity (mean percentage of looking time, ASD = 30.7% vs TD = 34.9%; Cohen’s d = 0.56; p value < 0.03) or looking at a moving toy (24.5% vs 33.2%; d = 0.65; p value < 0.001). Findings indicate that there are qualitative differences in allocation of visual attention to social stimuli across ages in ASD.ClinicalTrials.gov identifier: NCT02668991.

AbstractThe assessment of autism spectrum disorder (ASD) is based on semi-structured procedures addressed to children and caregivers. Such methods rely on the evaluation of behavioural symptoms rather than on the objective evaluation of psychophysiological underpinnings. Advances in research provided evidence of modern procedures for the early assessment of ASD, involving both machine learning (ML) techniques and biomarkers, as eye movements (EM) towards social stimuli. This systematic review provides a comprehensive discussion of 11 papers regarding the early assessment of ASD based on ML techniques and children’s social visual attention (SVA). Evidences suggest ML as a relevant technique for the early assessment of ASD, which might represent a valid biomarker-based procedure to objectively make diagnosis. Limitations and future directions are discussed.

Purpose Although individuals with an autism spectrum disorder (ASD) represent a small proportion of forensic psychiatric patients as a group they present with specific difficulties and needs. There is also evidence that if detained individuals with an ASD experience particular difficulties within custodial environments as a result of a mismatch between the difficulties associated with their ASD and the environmental demands. The purpose of this paper is to explore the experience of individuals with an ASD admitted to a high secure psychiatric care (HSPC) hospital. Design/methodology/approach Using both a semi-structured interview and a quality of life self-report measure (the Lancashire Quality of Life Profile) the experiences and views of seven patients with an ASD detained in one HSPC hospital were qualitatively explored. Findings Whilst a diverse range of negative and positive aspects of being within HSPC were identified by patients interviewed, those with prison experience thought HSPC was a less stressful environment with more therapeutic opportunities. As a group, patients with an ASD reported a similar or significantly better quality of life in many domains (global, leisure, financial and living situation) compared to other detained forensic patient groups. Practical implications Although most patients with an ASD interviewed reported positive experiences, there are a number of practical improvements that could be made within the hospital to reduce experienced stress levels and perhaps improve therapeutic outcomes. Originality/value Within the context of the Department of Health's autism strategy (2010) and subsequent update think autism (2014), the survey highlights continued ASD awareness training for staff as important. In responding to the risks and needs of individuals with an ASD in HSPC there is further support for the development of an ASD specialist service.

Purpose Patients with autism spectrum disorder (ASD) present with specific assessment, specific difficulties, needs and therapeutic issues and therefore are a challenging group for forensic services. Given the challenge that individuals with ASD present to forensic services, the suggested increase in the number of this group within this setting and the relatively little amount of research which suggests they face a number of difficulties within the prison environment, the purpose of this paper is to identify and review all the studies which have been carried out investigating any aspect of ASD in relation to secure hospital settings. Design/methodology/approach Seven internet-based bibliographic databases were used for the present review. The review followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. Findings A total of 12 studies were included in this review; 3 looked at the prevalence of ASD in secure psychiatric hospitals. One study evaluated the clinical utility of the AQ screening tool to assess self-reported autistic traits in secure psychiatric settings. Three explored any type of characteristics of patients with ASD detained in secure psychiatric hospitals. One study investigated the experiences or quality of life of patients with an ASD detained in secure psychiatric care. Two studies investigated awareness, knowledge and/or views regarding patients with ASD held by staff working within secure psychiatric hospitals. Lastly, three studies (one of which was also included in the prevalence category above) looked at the effectiveness of interventions or treatment of patients with ASD in secure psychiatric hospitals. Clinical recommendations and future research directions are discussed. Originality/value To the author’s knowledge, this is the first review to explore what research has been carried out looking specifically at patients with ASD in relation to secure forensic settings.

AbstractIn this study we investigate whether persons with autism spectrum disorder (ASD) perceive social images differently than control participants (CON) in a graded perception task in which stimuli emerged from noise before dissipating into noise again. We presented either social stimuli (humans) or non-social stimuli (objects or animals). ASD were slower to recognize images during their emergence, but as fast as CON when indicating the dissipation of the image irrespective of its content. Social stimuli were recognized faster and remained discernable longer in both diagnostic groups. Thus, ASD participants show a largely intact preference for the processing of social images. An exploratory analysis of response subsets reveals subtle differences between groups that could be investigated in future studies.

Social attention deficits represent a central impairment of patients suffering from autism spectrum disorder (ASD), but the nature of such deficits remains controversial. We compared visual attention regarding social (faces) vs. non-social stimuli (objects), in an ecological diagnostic context, in 46 children and adolescents divided in two groups: ASD (N = 23) and typical neurodevelopment (TD) (N = 23), matched for chronological age and intellectual performance. Eye-tracking measures of visual scanning, while exploring and describing scenes from three different tasks from the Autism Diagnostic Observation Schedule (ADOS), were analyzed: “Description of a Picture,” “Cartoons,” and “Telling a Story from a Book.” Our analyses revealed a three-way interaction between Group, Task, and Social vs. Object Stimuli. We found a striking main effect of group and a task dependence of attentional allocation: while the TD attended first and longer to faces, ASD participants became similar to TD when they were asked to look at pictures while telling a story. Our results suggest that social attention allocation is task dependent, raising the question whether spontaneous attention deficits can be rescued by guiding goal-directed actions.

Several recent studies have demonstrated reduced visual aftereffects, particularly to social stimuli, in autism spectrum disorder (ASD). This putative impairment of the adaptive mechanism in ASD has been put forward as a possible explanation for some of the core social problems experienced by children with ASD (e.g., facial emotion or identity recognition). We addressed this claim in children with ASD and typically developing children by using an established methodology and morphed auditory stimulus set for eliciting robust aftereffects to vocal expressions and phonemes. Although children with ASD were significantly worse at categorizing the vocal expressions compared with the control stimuli (phoneme categorization), aftereffect sizes in both tasks were identical in the two participant groups. Our finding suggests that the adaptation mechanism is not universally impaired in ASD and is therefore not an explanation for the social perception difficulties in ASD.

PurposeAutism spectrum disorder (ASD) is an exclusion criterion for one of the two attachment disorders in the DSM 5. However, previous findings indicate that ASD and attachment disorder are unrelated conditions and may co-occur. The purpose of this paper is to explore the diagnostic assessment of an adolescent male with ASD, intellectual disability (ID), severe challenging behaviour and a suspected attachment disorder.Design/methodology/approachCase study methodology was chosen because of its suitability in the exploration of complex clinical phenomena where prior knowledge is sparse.FindingsIt was possible to identify symptoms of attachment disorder in a case involving ASD, ID, anxiety and severe challenging behaviour. The Disturbances of Attachment Interview was particularly useful in this assessment, as was assessment of ASD symptoms and developmental history. Differentiating the two attachment disorders proved challenging.Research limitations/implicationsThere is a need for further research in ASD and attachment disorders not limited by current diagnostic categories.Practical implicationsCo-occurring symptoms of attachment disorder may be identified in individuals with ASD and ID, and exploration of these symptoms in assessments of children and adolescents with ASD/ID and challenging behaviour may be beneficial.Originality/valueThe study adds to previous findings on attachment disorder in ASD, demonstrating that identification of attachment disorder is possible even in the presence of a highly complex clinical picture involving severe challenging behaviour. It may also assist other clinicians in identifying and making more accurate assessment of attachment disorder in ASD and ID.
