Differences in social communication are common in highly verbal autistic adolescents and can interfere with development of friendships as well as lead to other co-occurring challenges. The purpose of this initial study was to assess whether targeted areas of social communication would improve following the implementation of a manualized social communication package with parent participation and school coordination. Autistic adolescents who demonstrated challenges with social communication participated in this study in the context of a rigorous concurrent multiple baseline experimental design.

The pathogenesis of Alzheimer's disease (AD) is primarily driven by brain accumulation of the amyloid-β-42 (Aβ42) peptide generated from the amyloid-β precursor protein (APP) via cleavages by β- and γ-secretase. γ-Secretase is a prime drug target for AD; however, its brain regional expression and distribution remain largely unknown. Here, we are aimed at developing molecular imaging tools for visualizing γ-secretase.

Purpose: Castration-resistant prostate cancer (CRPC) is the most common cause of death in men. The effectiveness of HDAC inhibitors has been demonstrated by preclinical models, but not in clinical studies, probably due to the ineffectively accumulation of HDACI in prostate cancer cells. The purpose of this work was to evaluate effects of a novel HDACI (CN133) on CRPC xenograft model and 22Rv1 cells, and develops methods, PET/CT imaging, to detect the therapeutic effects of CN133 on this cancer.

Children with autism spectrum disorder demonstrate challenges in socialization that can interfere with their participation in common childhood activities and can persist or worsen if not addressed. The purpose of this study was to assess whether individualized education program (IEP) social goals could be targeted by a supervised paraprofessional during a short-term inclusive summer camp program. Data were collected using a concurrent multiple baseline design across four children.

Increasing numbers of individuals with Autism Spectrum Disorder (ASD) are entering postsecondary education; however, many report feeling lonely and isolated. These difficulties with socialization have been found to impact students' academic success, involvement within the university, and overall well being. Therefore, the purpose of this study was to assess, within the context of a multiple-baseline across participants design, whether a structured social planning intervention would increase social integration for college students with ASD.

Research has demonstrated that incorporating restricted interests of an individual with autism into recess activities is effective at increasing socialization with typically developing peers. However, certain activity contexts may alter the reinforcing influence of the restricted repetitive behaviors (RRBs) depending on an individual's history in that activity. Using an alternating treatment design, this study examined whether an individual's history with an activity affected socialization.

Recent research suggests that children with autism spectrum disorder (ASD) may now be reliably identified in later infancy, highlighting the need for empirically-validated interventions for infants and toddlers with early symptoms of ASD. Using a multiple baseline design across 15- to 21-month-old toddlers, this study implemented a brief, parent-mediated, Pivotal Response Treatment program, focusing on improving expressive communication. The results indicated that verbal communication improved as a consequence of the intervention, with concomitant improvements in untreated areas for all participants.

The literature suggests that many individuals diagnosed with Autism Spectrum Disorder (ASD) experience challenges with recognizing and describing emotions in others, which may result in difficulties with the verbal expression of empathy during communication. Thus, there is a need for intervention techniques targeting this area. Using a multiple baseline across participants design, this study examined the effectiveness of a video-feedback intervention with a visual framework component to improve verbal empathetic statements and questions during conversation for adults with ASD.

Empirical studies have documented a variety of social abnormalities in infancy that indicate risk for later social and behavioral difficulties. There is very little research illustrating the presence of such behavioral vulnerabilities with frequent repeated measures, and the feasibility of designing interventions for improving social engagement in infants under one year of age. In the context of a multiple baseline research design, three young infants, ages 4, 7, and 9 months referred for concerns about social engagement were assessed for affect, social interest, eye contact avoidance, and response to name.

An important line of research relates to whether school personnel, such as paraprofessionals, who are present during unstructured social periods, such as lunch-recess, could successfully implement interventions to improve socialization between students with ASD and their typical peers in a group setting. Therefore, within the context of a multiple baseline across participants design, we assessed whether training paraprofessionals to provide social interventions would enhance social development in students with ASD in a group setting. Results showed that paraprofessionals who were not providing any social opportunities during baseline were able to meet fidelity of implementation following a brief training.

There has been a dramatic rise in the number of children being diagnosed with autism spectrum disorders (ASD), which has led to increased attention paid to assessment and intervention issues. This manuscript agrees with Camarata (2014) that the evidence base for early assessment and intervention should be expanded. However, it disagrees with Warren et al.

Individuals with autism spectrum disorders often exhibit difficulties with reciprocal social conversation, engaging in limited verbal exchanges, even when language structures are intact. This study employed a multiple baseline design to examine the effectiveness of a self-management intervention targeting (1) on-topic responsiveness to a conversational partner; (2) expansion of the conversational topic; and (3) on-topic question asking. Results demonstrated improved reciprocal social conversation through elaborated responses and on-topic question asking, which generalized and maintained.

Social initiations make up a core deficit for children with autism spectrum disorder (ASD). In particular, initiated questions during social interactions are often minimal or absent in this population. In the context of a multiple baseline design, the efficacy of using the motivational procedures of Pivotal Response Treatment to increase social question-asking for three young children with autism was assessed.

Prescription medications are commonly used for children with autism spectrum disorder (ASD), however, there is little research regarding how the effect of medication is monitored across settings once prescribed. The present study addressed this issue for children with ASD in school by administering a questionnaire to teachers of students with ASD who were and were not being given medication. Specifically, the questionnaire assessed the teachers' knowledge about whether the child was being given medication, and whether behavior changes or side effects were being communicated in any way to the child's family and prescribing physician.

There has been a paucity of research on effective social interventions for adolescents with autism spectrum disorders (ASD) in inclusive high school settings. The literature, however, suggests that incorporating the student with ASD's special interests into activities may help improve their socialization with typical peers. Within the context of a multiple baseline across participants design, we implemented lunchtime activities incorporating the adolescent with ASD's preferred interests that were similar to ongoing activities already available at the schools.

Verbal initiations, such as questions, are essential components of social conversation often lacking in children with autism. Building on research showing that single questions can be taught in isolation, this study used a multiple baseline design to investigate whether a self-management intervention was effective for teaching concurrent acquisition and discrimination of three social questions in the context of conversation. Following intervention, participants rapidly increased their appropriate use of all three questions in a conversational context and maintained these gains over time.

Children with Asperger's Disorder often have difficulty with peer relationships and socialization. The current study assessed whether peer social interactions would improve in school settings if an intervention was designed that incorporated the children with Asperger's interests. Three children who were fully-included in regular education classes but did not interact with peers prior to intervention participated in this research.

The literature suggests that adolescents with ASD typically are not socially engaged during unstructured school activities and do not initiate social activities with typically developing peers. This study assessed whether implementing socialization opportunities in the form of lunch clubs based around aspects of the adolescents with ASD's perseverative interests would promote positive direct and generalized social interaction between the target adolescent and their typically developing peers. A repeated measures multiple baseline experimental design (with two reversals) was implemented across participants.

Social engagement by children with autism spectrum disorder (ASD) in unstructured school settings generally occurs at very low levels, if at all. Although many interventions improve peer socialization, generalization and maintenance of such gains when interventions are faded are typically low. The present study employed a multiple baseline design across participants to target generalization in the absence of interventionists in elementary school children with ASD at recess.

The social vulnerabilities associated with young children with autism are recognized as important intervention targets due to their influence on subsequent development. Current research suggests that interventions that combine motivational and social components can create meaningful changes in social functioning. Simultaneously, it is hypothesized that parent delivery of such strategies can invoke increases in these core social behaviors and parent engagement.
