The effects of item preference and token reinforcement on sharing behavior exhibited by children with autism spectrum disorder / Caitlin GILLEY in Research in Autism Spectrum Disorders, 8-11 (November 2014)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 8-11 (November 2014) . - p.1425-1433 Titre : The effects of item preference and token reinforcement on sharing behavior exhibited by children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Caitlin GILLEY, Auteur ; Joel E. RINGDAHL, Auteur Article en page(s) : p.1425-1433 Langues : Anglais (eng) Mots-clés : Social skills  Autism spectrum disorder  Children  Token economy  Item preference  Sharing Index. décimale : PER Périodiques Résumé : The current studies evaluated variables affecting sharing exhibited by children with autism spectrum disorder. Study 1 evaluated the effects of manipulating item preference on the level of assistance needed to exhibit sharing behavior for 4 children with autism. Item preference clearly affected 2 participants’ percentage of independent sharing. Preference did not have as clear of an effect for a third participant. However, sharing a high-preference item generally required a higher level of prompting (e.g., vocal prompts) to share. The fourth participant's percentage of independent sharing was not influenced by preference, and his independent sharing behavior was similar across item preference. Study 2 assessed the effectiveness of a token reinforcement procedure as an intervention designed to increase independent sharing of high-preference items for the two participants who did not independently share those items during Study 1. Independent sharing increased for both participants when the token procedure was in place and decreased when it was removed.

A comparison of measures for assessing the level and nature of intelligence in verbal children and adults with autism spectrum disorder / Kimberly E. BODNER in Research in Autism Spectrum Disorders, 8-11 (November 2014)

The RPM measures ‘fluid intelligence’, an area for which it has been argued that persons with ASD have a relative strength. Given that measures of intelligence are used for establishing clinical diagnoses, for making educational decisions, and for group-matching in research studies, continued examination of this contention is warranted. In the current study, verbal children with ASD performed moderately better on the RPM than on the Wechsler scales; children without ASD received higher percentile scores on the Wechsler than on the RPM. Adults with and without ASD received higher percentile scores on the Wechsler than the RPM. Results suggest that the RPM and Wechsler scales measure different aspects of cognitive abilities in verbal individuals with ASD. For the verbal children and adults with ASD in the current study, the RPM and Wechsler scales have unique contributions that must be considered in context when establishing a baseline of cognitive function. The results of this investigation highlight the importance of thoughtfully selecting appropriate measures of intelligence consistent with clinical, educational, and research purposes, especially for verbal children and adults with ASD.

Given the importance of DTT in comprehensive interventions, evaluating procedures to increase social responsiveness and approach during DTT are warranted. The effect of antecedent strategies on social avoidance during DTT in two children with ASD was examined. A pairing procedure in which one therapist removed demands and paired social interaction with access to preferred toys and activities was compared to a demand procedure in which a therapist presented instructions. Social approach was higher and social avoidance was lower in sessions with the pairing therapist compared to the non-pairing therapist during the Pairing Intervention and during post-pairing demand sessions.

Impact of DSM-5 on epidemiology of Autism Spectrum Disorder / Luke Y. TSAI in Research in Autism Spectrum Disorders, 8-11 (November 2014)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 8-11 (November 2014) . - p.1454-1470 Titre : Impact of DSM-5 on epidemiology of Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Luke Y. TSAI, Auteur Article en page(s) : p.1454-1470 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder  Autistic Disorder  Pervasive developmental disorder  DSM-5  Epidemiology  Prevalence Index. décimale : PER Périodiques Résumé : This paper extensively and comprehensively reviews the literature on epidemiology of autism focusing on the prevalence rates of Autistic Disorder (AD) and Autism Spectrum Disorder (ASD), and the potential negative impact of DSM-5 ASD on future ASD prevalence studies. Between 1966 and 2013, there are 72 published prevalence studies of AD and 61 published studies of ASD. The AD has a broad range of prevalence rates and has shown a trend of increasing rates over time. But there are also some evidences showing that the increase seems to have leveled off. The current prevalence of AD is estimated in the range of 10–30 per 10,000 people (i.e., 1 in 1000 to 1 in 333). The ASD also has a wide range of prevalence rates with a median rate of 69.5 per 10,000 people (1 in 144). When the prevalence rates are subdivided into several sub-ranges (e.g., 10–20, 20–40, etc. per 10,000), it is difficult to pick a particular sub-range to represent the prevalence of ASD. The present review notes that several recent studies comparing the utility of DSM-IV/DSM-IV-TR ASD and the DSM-5 ASD have reported that about 9–54% of DSM-IV ASD cases do not qualify for the DSM-5 ASD. Suggestions of research designs for future ASD prevalence studies are offered.

Results indicate that the Clinical ASD group scored lower on the Externalizing Problems composite, Aggression, and Conduct Problems scales than did the No-ASD group whereas the Non-clinical ASD group did not differ from the other two groups except on the Conduct Problem scale. Further, the Clinical ASD group significantly scored lower than the other two groups the Adaptive Skills composite. The scores of the Clinical ASD group on the Social Skills and Leadership scales were lower than those in the No-ASD group, but not those in the Non-clinical ASD group. Results suggest that the frequent comorbid behavioral problems and higher adaptive skills of children in a non-clinical population, compared to a clinical population could mask their core ASD symptoms, resulting in a delay for caretakers to seek appropriate services for these children.

Exploring the persuasive writing skills of students with high-functioning autism spectrum disorder / Heather M. BROWN in Research in Autism Spectrum Disorders, 8-11 (November 2014)

Most previous studies of students with HFASD have combined individuals with linguistic impairments (HF-ALI) and individuals without linguistic impairments (HF-ALN) into a single group. The current study was the first to compare the persuasive writing of students with HF-ALN with controls, without confounding the effects of language ability and autism on writing achievement, and while considering possible cognitive underpinnings of their writing skills. Twenty-five students with HF-ALN and 22 typically developing controls completed measures of oral language, nonverbal IQ, social responsiveness, theory of mind, integrative processing and persuasive writing. The persuasive texts were coded on 19 variables across six categories: productivity, grammatical complexity, lexical diversity, cohesiveness, writing conventions, and overall quality. The texts were reliably different between groups across measures of productivity, syntactic complexity, lexical complexity and persuasive quality. Specifically, the texts of students with HF-ALN scored lower on overall quality (d = ?0.6 SD), contained shorter and simpler sentences (d = ?1.0), and had less repetition of content words (d = ?0.8 SD). For the HF-ALN group, integrative processing, language ability and age predicted 77% of the variance in persuasive quality.

Results One-fourth (25.8%) experienced chronic abdominal pain (duration ?3 months) at baseline, persisting at one-year follow-up for 86.7%. New onset pain occurred for 23.8% of those without baseline pain. Anxiety, SOR, and chronic abdominal pain were associated at baseline. SOR significantly predicted new onset pain, but neither anxiety nor SOR were predictors of pain remission. Conclusions Abdominal pain appears to be common and persistent among children with ASD. The relations among SOR, anxiety and abdominal pain offer information about potential underlying mechanisms.

This work has mainly focused on dyadic relationships in the family (especially parent–child reciprocal effects). In the present study, we extended a systems perspective in autism family research to a triad involving the child with autism, their mother, and a sibling, and also adopted a longitudinal design. Mothers from 60 families of children with autism reported on their own depression, and the behavior problems and pro-social behavior of their child with autism and a sibling. Results from longitudinal regression models suggested that earlier levels of maternal depression and sibling pro-social behavior did not have an independent effect on the behavior problems or pro-social behavior of children with autism 2.5–3 years later. Earlier levels of sibling behavior problems were associated with increased behavior problems of the child with autism 2.5–3 years later. Although replication is required, these are the first data to suggest that outcomes for children with autism may be affected by their siblings’ psychological adjustment. The methodology of longitudinal family systems analysis of triadic relationships has important research and practical implications.

The relationship between autism quotient, anxiety, and internet addiction / Michela ROMANO in Research in Autism Spectrum Disorders, 8-11 (November 2014)

Ninety participants were given a range of psychometric assessments to determine their level of problematic internet usage (Internet Addiction Test), autism traits (Autism Quotient Scale), depression (Beck Depression Inventory), and anxiety (Speilberger Trait Anxiety Scale). Significant associations were found between both autism, and anxiety, and internet addiction. However, the association between autism traits and internet addiction was moderated by high level for anxiety, such that individuals with high numbers of autism traits showed less evidence of internet addiction if they also displayed high levels of anxiety. It is suggested that the presence of anxiety in these individuals alters the function that internet behavior serves, and makes internet addiction less likely.

Specifically, caregivers of people with ASDs have been observed to have more somatic symptoms, poorer self-perceived general health, poorer social functioning and altered immune and endocrine systems. Various positive variables including emotional intelligence (EI) have been found to protect health in several populations, but no studies have previously analyzed the effect of EI in caregivers of people with ASDs. The present study aimed to analyze the association of the three components of EI (attention, clarity and repair) with self-reported health and cortisol awakening response (CAR) in caregivers of offspring with ASD. Attention was negatively associated and clarity positively associated with self-reported health. Clarity and repair were associated with a lower magnitude of CAR, estimated by the area under the curve with respect to ground (AUCg). Moreover, CAR AUCg was a mediator in the association of clarity and repair with self-perceived general health. These results confirm that EI components have different effects on health in caregivers of people with ASDs. EI should be included as a target of interventions to improve health in this population.

The present study hypothesized that the magnitude of the other-race effect shall be reduced in individuals with ASD owing to their inattention to faces since infancy. Using a sequential face discrimination task, we tested the other-race effect of 18 ASD (mean age = 7.5 years) and 13 age-matched typically developing (TD) children (mean age = 7.6 years). The stimuli were cropped Asian and African faces, each with four levels of difficulty: easy (change identity), medium (replaced eyes), hard-eye (widen eye spacing), and hard-mouth (moved up mouth). The TD children showed a significant own-race advantage such that the best performance was found in the Asian easy condition. The ASD children did not exhibit such advantage at all. Moreover, ASD children showed the highest error rates in the hard-eye condition instead of the hard-mouth condition, indicating insensitivity to eyes region. In sum, our findings support the hypothesis that the other-race effect is reduced in ASD children, reflecting an incomplete development of an expert face system.

Developmental assessments were conducted at 6, 12, 24 months, and 3 years, with blinded “clinical best-estimate” expert diagnosis at age 3. HR infants were enrolled based only on familial risk. LR infants, from community sources, had no first- or second-degree ASD relatives. All infants were born at 36–42 weeks, weighing ?2500 g, with no identifiable neurological, genetic, or severe sensory/motor disorders. Analytic phase I: semi-parametric group-based modeling to identify distinct developmental trajectories (n = 680; 487 HR; 193 LR); phase II: Trajectory membership in relation to 3-year diagnosis (n = 424; 310 HR; 114 LR). Three distinct trajectories emerged (1) inclining; (2) stable-average; (3) declining; trajectory membership predicted diagnosis (?2 = 99.40; p lt; .001). Most ASD cases were in stable-average (50.6%) or declining trajectories (33.8%); most non-ASD-HR infants were in inclining (51.9%) or stable-average (40.3%) trajectories. The majority of LR controls were in the inclining trajectory (78.9%). Within the declining trajectory, over half had ASD (57.8%), but 40% were non-ASD-HR infants. Declining/plateauing raw scores were associated with, but not exclusive to, ASD. Findings underscore the importance of monitoring the emergence of ASD symptoms and overall development in high-risk children. Evidence of developmental slowing or decline may be associated not only with ASD, but with other suboptimal outcomes, warranting careful clinical follow-up.

To better understand the relationships among these neural and behavioral abnormalities, we examined cortical connectivity which was indicated by theta coherence during tasks of facial emotion recognition in 18 children with ASD and 18 typically developing (TD) children who were between 6 and 18 years of age. We found that the children with ASD had general impairment in recognizing facial emotions, after controlling for response bias. Additionally, we found that the TD children demonstrated significant modulation of right frontal theta coherence in response to emotional faces compared to neutral faces, whereas children with ASD did not exhibit any modulation of theta coherence. The extent of modulation of theta coherence to emotions was further found to be related to the severity of social impairments in ASD. Our findings of a general impairment in facial emotion recognition and the involvement of disordered cortical connectivity in social deficits in children with ASD have shed light for future exploration of interventions regarding emotional processing and social functioning in ASD.

Stereotyped and repetitive behaviors are also present. Along with these core symptoms, a number of co-occurring problems such as aggression are present. The present study reviewed papers that describe various characteristics of aggressive behaviors among persons with ASD. The preponderance of studies involved children who were male. Aggression was more severe in males. Where the maintaining variables were studied, tangible and escape, and some core aspects of ASD such as cognitive rigidity and poor social and communication skills, were associated with aggression. The implication of these data and other characteristics of this challenging behavior are discussed.

Early intervention for autism: Who provides treatment and in what settings / Johnny L. MATSON in Research in Autism Spectrum Disorders, 8-11 (November 2014)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 8-11 (November 2014) . - p.1585-1590 Titre : Early intervention for autism: Who provides treatment and in what settings Type de document : Texte imprimé et/ou numérique Auteurs : Johnny L.

KONST, Auteur Article en page(s) : p.1585-1590 Langues : Anglais (eng) Mots-clés : Autism  Early intervention  Parents  Applied behavior analysis  Treatment Index. décimale : PER Périodiques Résumé : Early intensive interventions have become popular. Thus, not surprisingly, the amount of research surrounding this topic has increased and evolved rapidly. The persons providing treatment, the settings in which treatment is provided, and the methods used have varied considerably. This paper reviews current trends. For example, 20–40 h of therapy weekly has consistently characterized the literature. Conversely, the role of parents has transformed as they have increasingly become co-therapists. One major concern is that little effort has been put into the transition from these intensive programs to educational settings. These factors and related parameters are reviewed and the implications are discussed.

Assisting students with autism to actively perform collaborative walking activity with their peers using dance pads combined with preferred environmental stimulation / Ching-Hsiang SHIH in Research in Autism Spectrum Disorders, 8-11 (November 2014)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 8-11 (November 2014) . - p.1591-1596 Titre : Assisting students with autism to actively perform collaborative walking activity with their peers using dance pads combined with preferred environmental stimulation Type de document : Texte imprimé et/ou numérique Auteurs : Ching-Hsiang SHIH, Auteur ; Man-Ling CHANG, Auteur ; Shu-Hui WANG, Auteur ; Chang-Lu TSENG, Auteur Article en page(s) : p.1591-1596 Langues : Anglais (eng) Mots-clés : ASD  FPPDP  Dance pad  Collaborative walking activity Index. décimale : PER Périodiques Résumé : The purpose of this study was to provide students with autism spectrum disorders (ASDs) the opportunity to cooperate with their peers. This experiment was designed so that students with ASD and their partners were required to perform the collaborative walking activity using dance pads combined with preferred stimulation. With the foot-pressing position detection program (FPPDP) software, standard dance pads could be used as foot-pressing position detectors to detect participants’ collaborative walking activities. An ABAB design was adopted in this experiment, where A represented baseline phases, and B represented intervention phases. The experimental results show that the participants increased their willingness to perform the assigned task and the actual amount of collaborative walking activity also increased during the intervention phases compared to the baseline phases. Practical and developmental implications of the findings are discussed.

Normative sample of the PEAK relational training system: Direct training module and subsequent comparisons to individuals with autism / Mark R. DIXON in Research in Autism Spectrum Disorders, 8-11 (November 2014)

ROWSEY, Auteur Article en page(s) : p.1597-1606 Langues : Anglais (eng) Mots-clés : PEAK  Language  Cognition  Autism  Normative data Index. décimale : PER Périodiques Résumé : The present data provide a normative sample of the PEAK: direct training module assessment and a subsequent comparison to individuals with autism. Altogether, 206 typically developing participants and 94 participants with autism took part in the study. For the normative sample, there was a strong relationship between PEAK total score and age (r = .659, p lt; .01), and a cubic regression provided a strong fit for the data (R2 = .821, t = 18.51, p lt; .01). The results from the autism sample suggest that there was no significant correlation between PEAK total score and age (r = .021, p = .861), and that PEAK total scores for the autism group were significantly lower than the normative sample (t(275) = 10.63, p lt; .001). The data suggest that PEAK may be especially useful as an assessment and curriculum guide for individuals with autism, and future research should be conducted on the increasingly complex topographies of human language and cognition that PEAK affords clinicians.

Inflectional morphology in high-functioning autism: Evidence for speeded grammatical processing / Matthew WALENSKI in Research in Autism Spectrum Disorders, 8-11 (November 2014)

MOSTOFSKY, Auteur ; Michael T. ULLMAN, Auteur Article en page(s) : p.1607-1621 Langues : Anglais (eng) Mots-clés : Autism  Language  Morphology  Past tense  Procedural memory  Basal-ganglia Index. décimale : PER Périodiques Résumé : Autism is characterized by language and communication deficits. We investigated grammatical and lexical processes in high-functioning autism by contrasting the production of regular and irregular past-tense forms. Boys with autism and typically developing control boys did not differ in accuracy or error rates. However, boys with autism were significantly faster than controls at producing rule-governed past-tenses (slip-slipped, plim-plimmed, bring-bringed), though not lexically dependent past-tenses (bring-brought, squeeze-squeezed, splim-splam). This pattern mirrors previous findings from Tourette syndrome attributed to abnormalities of frontal/basal-ganglia circuits that underlie grammar. We suggest a similar abnormality underlying language in autism. Importantly, even when children with autism show apparently normal language (e.g., in accuracy or with diagnostic instruments), processes and/or brain structures subserving language may be atypical in the disorder.
