The effects of tact training on stereotypic vocalizations in children with autism

This study was a systematic extension of Karmali, Greer, Nuzzulo-Gomez, Ross, and Rivera-Valdes (2005) and Ahearn, Clark, MacDonald, and Chung (2007). We investigated the effects of a tact correction procedure on stereotypic vocalizations in 4 children diagnosed with autism who ranged in age from 6 to 16 years. Participants had limited vocal verbal repertoires and were primarily dependent on prompts for the emission of appropriate vocalizations. A multiple-baseline design across participants was used. Data were collected on instances of stereotypic vocalizations and independent tacts during baseline conditions and on instances of stereotypic vocalizations, independent tacts, and echoic-tacts during intervention. Procedural integrity and social validity data were also obtained. The results indicated a decrease in stereotypic vocalizations for 3 of the 4 participants and a slight increase in appropriate vocal verbal behavior (i.e., tacting) for all participants. The study provides support for the use of tact correction procedures to decrease stereotypic vocalizations and increase appropriate vocalizations in children with autism.     

The effects of listener training on the emergence of tact and mand signs by individuals with intellectual disabilities

The purpose of the current study was to assess whether individuals with intellectual disabilities would emit untrained speaker responses (i.e., signed tacts and mands) after being taught listener behaviors. Listener relations were trained via an automated matching-to-sample (MTS) procedure. Following mastery, the emergence of signed tacts, generalized tacts, and mands was tested. All participants met criterion in listener relations training and showed the emergence of almost all relations. Results suggest that teaching listener relations first, through MTS tasks, is a viable way to produce emergence of speaker relations.     

Companion animals in families of children with autism spectrum disorder: Lessons learned from caregivers.

Companion animals (i.e., pets) have been increasingly recognized for the roles they play in families, including those with children with Autism Spectrum Disorder (ASD). This cross-sectional study explored the unique functions of companion animals within families with a child with ASD. Phenomenology was used to analyze the responses of participants (N = 338) who responded to a survey offered through the Interactive Autism Network. The study initially focused on dogs; however, the analysis was forced to expand to other species due to the data provided by participants. Seven major themes emerged: bonding and benefits, learning opportunities, barriers, grief, fit (match of family characteristics with those of the companion animal), safety, and alternative animals. Successful fit between companion animals and families was often described as necessary for beneficial functions. Barriers included necessary cost and time, as well as required supervision of interactions to enhance safety of the children and animals.     

Emergent Intraverbal and Reverse Intraverbal Behavior Following Listener Training in Children with Autism Spectrum Disorder

We evaluated whether intraverbal and reverse intraverbal behavior emerged following listener training in children with autism spectrum disorder (ASD). Six participants were each taught three sets of three “when?” questions in listener training. A multiple baseline design across behaviors (stimulus sets) was used to assess the effects of listener training. Results showed that intraverbal behavior emerged following listener training for five out of six participants. One participant received additional listener training and intraverbal training before intraverbal behavior emerged. Furthermore, reverse intraverbal responding occurred across all three sets of questions for three of the six participants. Establishing listener behavior may be a pathway for emergent intraverbal and reverse intraverbal responding in children with ASD. Future research could examine what skill repertoire may facilitate such transfer.     

The white native speaker and inequality regimes in the private English language school

Private English language schools market the language as a tool that helps one connect with others from different cultures. Despite their promotion of English aiding in intercultural communication, these institutions may believe that only the white native speaker is the ideal teacher of the language. This valuing of the white native speaker can consequently act as an organisational inequality regime that marginalises nonwhite teachers. Using qualitative interviews with 10 nonwhite instructors working in schools in Toronto, Canada, this article investigates the ways in which these teachers experience the inequality regime of the white native speaker at work. The findings indicate that the teachers experience this inequality regime as a series of microaggressions that involve space, competence and customer desire. The article concludes with suggestions to dismantle inequality regimes in private institutions.     

Two decades of serving children with autism in the People’s Republic of China: achievements and challenges of a state‐run mental health center

This article presents the results of research conducted at the first place where autism was diagnosed in China, the Nanjing Child Mental Health Research Center. The purpose was to examine the development of service provision for children with autism in this state‐run medical institution. Specifically, the specific intervention model for autism, factors influencing the development of this model and how structural and organizational features of the institution impact on the implementation of that model are examined. Results indicate: (1) the importance of family involvement in intervention due to limited services in China; (2) the challenges of providing educational services at a medical institution during the reform period. The implications of these services in contemporary China are significant to consider as an important way to address the rights of individuals with disabilities to have equal opportunities in society, beginning with early education.     

Under-detection of autism among First Nations children in British Columbia,Canada

This article shows that First Nations children diagnosed with autism in British Columbia, Canada are under-represented in publications regarding autism and the prevalence thereof, and that this group appears to be under-detected. The aim of this review of publications regarding autism and aboriginal populations in Canada and other countries is to examine possible explanations. The research review results suggest that possible reasons for under-detection of autism among aboriginal populations, and consequently First Nations peoples, can be diagnostic substitution and symptom presentation, ethnic or cultural, area of residence or the impact of historical oppression and discrimination.     

The embodied becoming of autism and childhood: a storytelling methodology

In this article I explore a methodology of storytelling as a means of bringing together research around autism and childhood in a new way, as a site of the embodied becoming of autism and childhood. Through reflection on an ethnographic story of embodiment, the body is explored as a site of knowledge production that contests its dominantly storied subjectivation as a ‘disordered’ child. Storytelling is used to experiment with a line of flight from the autistic-child-research assemblage into new spaces of potential and possibility where the becomings of bodies within the collision of autism and childhood can be celebrated.     

More on the ontological status of autism and double empathy

This response to Milton’s recent article on the ontological status of autism and double empathy also explores, through the lens of ‘double empathy’ and ‘theory of mind’, the issues of relationality and interaction that researchers in the fields of cognitive neuroscience and psychology hardly acknowledge. I go on to consider Wittgenstein’s criteriological view of mind, propose a synthesis of theory to describe autism, and suggest that public criteria of a non-autistic ontology enable many autistic people to eventually develop the understanding of other (non-autistic) minds that, in turn, enables them to survive, and even thrive.     

Positioning,strategizing, and charming: how students with autism construct identities in relation to disability

Contrary to views that young people with the label of autism are incapable of engaging in collective cultural practice, this article examines how they construct identities through social interactions to belong, compete, and participate. In a multi-sited ethnography of high school students with disabilities, we focused on two students as they move across contexts of school, debate team, and home. Over two years of interviews and participant observation, these students demonstrated nuanced efforts to distance themselves from the ‘autistic’ label. These acts of positioning illuminated how they negotiate identities with the knowledge their interactions shape how people perceive their participation in different contexts. By following them across informal and formal environments, we could see how they transition across multiple social worlds and appreciate the combined power these contexts have on youth identity.     

Dialect stabilization and speaker awareness in non‐native varieties of English1

Research on indigenized non‐native varieties of English has aimed to distinguish these varieties from individual second language learning in structural and social terms ( B. Kachru 1983 ; Platt, Weber and Ho 1984 ; Cheshire 1991 ) ; however, quantitative evidence of this divergence remains scarce. Through an analysis of a range of Indian English speakers in a contact situation in the United States, this study distinguishes developing dialect features from second language learning features and explores the concomitant emergence of dialect consciousness. First, an implicational analysis shows that some non‐standard variables (past marking, copula use, agreement) exhibit a second language learning cline while others (articles) form a more stable, incipient non‐standard system shared to some extent by all speakers; a multivariate analysis suggests that both sets of variables are governed by proficiency levels. Next, the explanatory scope of proficiency is assessed by examining the use of selected phonological variants (rhoticity, l‐velarization, aspiration). The use of these features resembles native‐like style‐shifting, as it appears to be more sensitive to speakers’ attitudinal stances than to proficiency levels. This points to the importance of understanding emerging speaker awareness and perceptions of stigma, risk, and value in new varieties of English.     

Using a lag schedule to increase variability of verbal responding in an individual with autism

Research has shown that reinforcing novel behaviors can increase the number of different ways that an individual behaves (Goetz & Baer, 1973; Pryor, Haag, & O'Reilly, 1969). However, it was not until more recently that researchers began to consider variability to be a reinforceable operant in and of itself (Neuringer, 2002). More specifically, Neuringer suggested that variability can be taught using a Lag x schedule of reinforcement, in which x refers to the number of previous responses from which the current response must differ in order for reinforcement to occur (Page & Neuringer, 1985). The purpose of the present study was to extend one of the first studies of a Lag x schedule on verbal responses with human subjects (Lee, McComas, & Jawor, 2002), by increasing the lag criteria while attempting to address some of methodological limitations of the study. The participant was a 7-year-old male with autism. A changing criterion design was used and results showed that 3 novel responses were acquired and varied according to the lag schedule of reinforcement.     

A qualitative investigation of risk and protective factors for interpersonal violence in adults on the autism spectrum

Abstract

Individuals on the autism spectrum are at an increased risk of experiencing violence. This study sought to understand the opinions of adults on the spectrum regarding potential risk and protective factors for interpersonal violence. Twenty-two adults (12 men; 18 to 53 years of age) participated in semi-structured qualitative interviews. Interviews were recorded, transcribed, and analysed. The results of the qualitative analysis identified individual and contextual risk and protective factors. Protective themes focused on individual needs (awareness of the self and the environment, interpersonal knowledge/skills, skill building strategies) and supportive contexts (benefits of a trusted person, advocates, fostering acceptance and inclusion). There is a need for strategies to decrease the vulnerability to, and the impact of, interpersonal violence. Individuals on the spectrum have the capacity to provide important information regarding safety promotion and risk factors for interpersonal violence, and their expertise should play a role in guiding efforts that promote safety.     

Spirituality in Latino families of children with autism spectrum disorder

Research on Latino parents of children with intellectual and developmental disabilities (IDD) suggests that these parents often use spirituality to conceptualize and to cope with their child’s diagnosis. However, there are no studies that examine religion among Latino parents of children with autism spectrum disorders (ASD). The current study explores how Latino parents of children with ASD incorporate spirituality into their conceptualizations of their child’s disability. In the current study, 34 Latina mothers of children with ASD were interviewed about autism-related services, family characteristics, and cultural beliefs including spiritual beliefs. Thematic analysis of the transcribed interview data relating to spiritual beliefs was conducted for the present study. Most mothers endorsed beliefs that their child with a disability was a message from God. Within this theme, mothers reported beliefs that their child was a blessing from God, a test from God, a sign from God or that the parent was special. Other parents believed that having a child with a disability was not an act of God, but related to biomedical factors, and another group of parents was unsure about the spiritual meaning of their child with a disability. Lastly, some mothers reported that their larger cultural group believed that having a child with a disability was a punishment or a negative sign from God but they markedly rejected that conception. These findings suggest that providers working with Latino families of children with ASD should acknowledge the importance of spirituality for these families.     

The effects of strength training on memory in older adults

The authors examined whether resistance training has an effect on working memory span. Participants included 210 community-residing older adults with at least one disability from the Strong for Life program, a randomized controlled trial that examined the effects of home-based resistance exercise. Memory was assessed with the WAIS backward digit span at baseline and 3 and 6 months into the intervention. Although there were no differences between the experimental treatment and control groups in average levels of memory change, within the treatment group change in resistance level during the intervention was a significant predictor of memory change, controlling for age, education, sex, and disability level. The results suggest that strength training can benefit memory among older adults, especially when using higher resistance levels.     

The effects of respiratory-muscle training on exercise in older women

This research examined the effects of respiratory-muscle (RM) training on RM function and exercise performance in older women. Twenty-six women (60-69 yr of age) were assessed for spirometry, RM strength (maximal inspiratory and expiratory pressure), inspiratory-muscle endurance, and walking performance to a perceived exertion rating of "hard." They were randomly allocated to a threshold RM training group (RMT) or a nonexercising control group (CON) for 8 wk.After training, the 22% (inspiratory) and 30% (expiratory) improvements in RM strength in the RMT group were significantly higher than in the CON group (p < .05). The RMT group also displayed several significant performance improvements, including improved within-group treadmill performance time (12%) and reductions in submaximal heart rate (5%), percentage of maximum voluntary ventilation (16%), and perceived exertion for breathing (8%). RM training appears to improve RM function in older women. Furthermore, these improvements appear to be related to improved submaximal exercise performance.     

The effects of regulation on public sector labor relations: Theory and evidence

This paper assesses the effects of public sector collective bargaining laws on employee unionization, the bargaining process and bargaining outcomes, including pay, benefits and nonmonetary aspects of employment. Although several specific effects — positive and negative, direct and indirect — of regulation in this area have been reported by researchers, most studies do not deal adequately with the issues of model specification or simultaneity, thus calling their validity into question. The helpful comments of Professors John T. Delaney, Craig Olson, and Donna Sockell are gratefully acknowledged.     

The effects of high- and moderate-resistance training on muscle function in the elderly

The purpose of this study was to investigate the effects of a 12-week resistance-training program on muscle strength and mass in older adults. Thirty-three inactive participants (60-74 years old) were assigned to 1 of 3 groups: high-resistance training (HT), moderate-resistance training (MT), and control. After the training period, both HT and MT significantly increased 1-RM body strength, the peak torque of knee extensors and flexors, and the midthigh cross-sectional area of the total muscle. In addition, both HT and MT significantly decreased the abdominal circumference. HT was more effective in increasing 1-RM strength, muscle mass, and peak knee-flexor torque than was MT. These data suggest that muscle strength and mass can be improved in the elderly with both high- and moderate-intensity resistance training, but high-resistance training can lead to greater strength gains and hypertrophy than can moderate-resistance training.     

The Effects of Deprivation, Presession Exposure, and Preferences on Teaching Manding to Children with Autism

The effects of at least 23-hr deprivation, 5-min presession exposure, and individual preference on the acquisition of mands were investigated in these studies. Two boys who were 2.5 years old and diagnosed with autism participated in the studies. Preference assessments were conducted to identify preference levels of various toys. Toys of various preferences were then assigned to either a 23-hr deprivation or 5-min presession exposure condition for mand training. Both deprivation and preference level affected acquisition of mands. Implications for teaching children to mand are discussed.
