Experimentally Induced Increases in Early Gesture Lead to Increases in Spoken Vocabulary

Differences in vocabulary that children bring with them to school can be traced back to the gestures they produced at the age of 1;2, which, in turn, can be traced back to the gestures their parents produced at the same age (Rowe & Goldin-Meadow, 2009a Rowe, M. L. & Goldin-Meadow, S. (2009a). Differences in early gesture explain SES disparities in child vocabulary size at school entry. Science, 323, 951–953.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). We ask here whether child gesture can be experimentally increased and, if so, whether the increases lead to increases in spoken vocabulary. Fifteen children aged 1;5 participated in an 8-week at-home intervention study (6 weekly training sessions plus follow-up 2 weeks later) in which all were exposed to object words, but only some were told to point at the named objects. Before each training session and at follow-up, children interacted naturally with caregivers to establish a baseline against which changes in communication were measured. Children who were told to gesture increased the number of gesture meanings they conveyed, not only during training but also during interactions with caregivers. These experimentally induced increases in gesture led to larger spoken repertoires at follow-up.     

Family Stress and Adjustment as Perceived by Parents of Children with Autism or Down Syndrome: Implications for Intervention

ABSTRACT

This study examined stress and adjustment in parents of three groups of families: those with an autistic child, those with a Down syndrome child, and those with only developmentally normal children. A total of 54 families participated, with 18 representing each group. Parents of autistic children generally reported more family stress and adjustment problems than parents of children with Down Syndrome who, in turn, reported more stress and adjustment problems than parents of developmentally normal children. Although parents of disabled children reported more stress associated with caring for their child, they generally showed resilience in adjusting to the presence of a severely disabled family member. Implications for family intervention are discussed.

Relationship Quality as a Moderator of Anxiety in Siblings of Children Diagnosed with Autism Spectrum Disorders or Down Syndrome

The purpose of this study was to examine typically-developing adolescents’ perceived relationship quality with their developmentally-disabled sibling, specifically siblings diagnosed with an autism spectrum disorder (ASD) or Down syndrome (DS). The 119 eleven through seventeen-year-old adolescent participants (M = 13.32, SD = 1.90) completed an online survey that assessed demographics, sibling relationship quality, and anxiety. Results showed that siblings of children with DS have a greater overall sibling relationship quality than do siblings of children with an ASD. Results further indicated that reporting more negative interchanges within the sibling relationship was related to higher levels of anxiety regardless of sibling disability type. Lastly, sibling relationship quality moderated the relation between sibling disability type and anxiety. These findings promote greater understanding of the sibling dynamic in families with children with developmental disabilities and suggest the need for establishing more research and greater clinical evaluation in this area. Furthermore, the current study suggests that therapeutic intervention to address the sibling relationship quality within children diagnosed with ASDs and their typically-developing siblings would be beneficial in order to increase social support within the relationship as well as decrease the amount of negative interchanges within the sibling relationship. Results also suggested that decreasing the amount of negative interchanges within the sibling relationship may decrease the level of anxiety the typically-developing sibling reports.     

Antecedent Selection: Comparing Simplified and Typical Verbal Antecedents for Children with Autism

This study measured the differential effects of simplified and typical verbal antecedents on acquisition of picture discriminations for four preschool children with autism. During baseline probes, participants emitted no correct selection responses to pictures of common stimuli during either simplified or typical verbal antecedent conditions. Using an adapted alternating treatments design during training, instructors presented a simplified verbal antecedent (i.e., “Give me car”) or a typical verbal antecedent (i.e., “One of these is a car. Which one is it?”), and differentially reinforced participants’ correct selection responses given the target picture and two non-targets. Results showed that one participant emitted more correct responses during simplified than typical verbal antecedent conditions, one participant emitted more correct responses during typical than simple verbal antecedent conditions, and there was no clear difference for the other two participants.

Learning,Attention, Writing,and Processing Speed in Typical Children and Children with ADHD,Autism, Anxiety,Depression, and Oppositional-Defiant Disorder

Learning, attention, graphomotor, and processing speed scores were analyzed in 149 typical control children and 886 clinical children with normal intelligence. Nonsignificant differences were found between control children and children with anxiety, depression, and oppositional-defiant disorder. Control children performed better than children with ADHD and autism in all areas. Children with ADHD and autism did not differ, except that children with ADHD had greater learning problems. Attention, graphomotor, and speed weaknesses were likely to coexist, the majority of children with autism and ADHD had weaknesses in all three areas, and these scores contributed significantly to the prediction of academic achievement.     

Cost Comparison of Early Intensive Behavioral Intervention and Special Education for Children with Autism

The financial implications of the increased prevalence of autism, though rarely discussed, will be extremely important to society. We compared the costs associated with 18 years of special education to the costs associated with the implementation of an average of 3 years of Discrete Trial Training as an Early Intensive Behavioral Intervention (EIBI) in an effort to minimize the need for special education. Our results indicate that the state of Texas would save $208,500 per child across eighteen years of education with EIBI. When applied to the conservative estimate of 10,000 children with autism in Texas, the State would save a total of $2.09 billion with EIBI. Implications for taxpayers, policymakers, and treatment are discussed.     

Stories of Life Transition: Subjective Well-Being and Ego Development in Parents of Children with Down Syndrome

Eighty-seven parents of children with Down Syndrome (DS; 63 women, 24 men) wrote narratives about finding out that their child had DS and completed questionnaire measures of subjective well-being (SWB) and stress-related growth and completed the Sentence Completion Test as a measure of ego development. Forty-two of these individuals participated in a follow-up 2 years later. Foreshadowing and happy endings in the stories were related to heightened SWB at both time periods. Evidence of accommodative change—actively experiencing a paradigmatic shift—was related to stress-related growth and ego development at both time periods. A high sense of closure and accommodation in the stories was associated with the highest levels of stress-related growth. Implications for research on well-being and personal growth are discussed.     

Early Negative Affect Predicts Anxiety, not Autism, in Preschool Boys with Fragile X Syndrome

Children with fragile X syndrome (FXS) face high risk for anxiety disorders, yet no studies have explored FXS as a high-risk sample for investigating early manifestations of anxiety outcomes. Negative affect is one of the most salient predictors of problem behaviors and has been associated with both anxiety and autistic outcomes in clinical and non-clinical pediatric samples. In light of the high comorbidity between autism and anxiety within FXS, the present study investigates the relationship between longitudinal trajectories of negative affect (between 8 and 71 months) and severity of anxiety and autistic outcomes in young males with FXS (n?=?25). Multilevel models indicated associations between elevated anxiety and higher fear and sadness, lower soothability, and steeper longitudinal increases in approach. Autistic outcomes were unrelated to negative affect. These findings suggest early negative affect differentially predicts anxiety, not autistic symptoms, within FXS. Future research is warranted to determine the specificity of the relationship between negative affect and anxiety, as well as to explore potential moderators. Characterizing the relationship between early negative affect and anxiety within FXS may inform etiology and treatment considerations specific to children with FXS, as well as lend insight into precursors of anxiety disorders in other clinical groups and community samples.

Spoken and gestural production in a naming task by young children with Down syndrome

Lexical production in children with Down syndrome (DS) was investigated by examining spoken naming accuracy and the use of spontaneous gestures in a picture naming task. Fifteen children with DS (range 3.8-8.3 years) were compared to typically developing children (TD), matched for chronological age and developmental age (range 2.6-4.3 years). Relative to TD children, children with DS were less accurate in speech (producing a greater number of unintelligible answers), yet they produced more gestures overall and of these a significantly higher percentage of iconic gestures. Furthermore, the iconic gestures produced by children with DS accompanied by incorrect or no speech often expressed a concept similar to that of the target word, suggesting deeper conceptual knowledge relative to that expressed only in speech.     

Autism,Attachment and Parenting: A Comparison of Children with Autism Spectrum Disorder,Mental Retardation,Language Disorder,and Non-clinical Children

Children with Autism Spectrum Disorder (ASD) have severe and pervasive impairments in the development of social interaction, which may affect the attachment relationship with their parents and may have an impact on parenting. In the current investigation 89 families with young children (mean age 26.5 months) were involved, who were diagnosed as ASD, mentally retarded (MR), or language delayed (LD), or part of a non-clinical comparison group. Attachment security was observed with the Brief Attachment Screening Questionnaire, and several parental self-report questionnaires assessed the parenting style, parental efficacy, parental experiences of daily hassles, social support, and psychological problems. Children with ASD were rated as less secure compared to the other clinical and normal comparison groups. Parents of non-clinical children reported higher levels of authoritative parenting than parents in the ASD group and in the total clinical group, and they also received less social support. Parents of children with ASD coped remarkably well with the challenges of raising a child with ASD.     

Breaking Difficult News in a Cross-cultural Setting: a Qualitative Study about Latina Mothers of Children with Down Syndrome

Giving difficult news to patients represents a common dilemma for health care professionals. Based on three decades of research, various authors have proposed guidelines outlining the ideal setting, delivery, and timing. Existing publications focus on patients of European descent and may not be applicable in cross-cultural settings. We explored perceptions of Spanish-speaking mothers who have a child with Down syndrome and how they preferred to receive the news of their child's diagnosis. We conducted semi-structured qualitative interviews (n?=?14), which were coded and analyzed by thematic networks to identify common themes. Six significant themes emerged: Cultural Belief System, Communication, Support/Lack of Support, Feelings Engendered, Medical Issues, and Medical System. One overarching theme of mother-child bonding encompassed all sub-themes. The mothers desired the news in a more positive, balanced light and with more complete explanations about the condition. Mothers felt excluded from the diagnostic process and wanted to be better informed about the need for diagnostic studies. Participants used religious beliefs to explain the reason for their child's condition. Many factors influenced Latina mothers' ability to bond initially with their children with Down syndrome. Ideally, these factors should be acknowledged during informing interviews to assist Latino families in adjustment.     

The Early Presentation of Dementia in People with Down Syndrome: a Systematic Review of Longitudinal Studies

Adults with Down syndrome (DS) are at a very high risk of developing early onset Alzheimer’s disease (AD) due to trisomy of chromosome 21. AD is preceded by a prolonged prodromal “pre-clinical” phase presenting with clinical features that do not fulfil the diagnostic criteria for AD. It is important to clinically characterise this prodromal stage to help early detection of the disease as neuropathology of AD is almost universal by the fifth decade in DS. There is a lack of knowledge of the trajectory of decline associated with the onset of dementia in this population and early signs may be overlooked or misdiagnosed, negatively affecting the quality of life of those affected and the use of early pharmacological or psychosocial interventions. The objective of this systematic review is to evaluate the published literature on longitudinal data in order to identify the cognitive and behavioural changes occurring during the prodromal and early stages of AD in this population. Fifteen peer-reviewed articles met the inclusion criteria, including a total number of 831 participants, with the duration between baseline and follow up varying from 1 year to 47 years. Results suggest that, compared to the general population for which short-term (episodic) memory loss is the most common indicator associated with the onset of AD, in people with DS, executive dysfunction and Behavioural and Psychological Symptoms of Dementia (BPSD) are commonly observed during pre-clinical and early stages and may precede memory loss. The review highlights the importance of using a broad spectrum of assessments in the context of heterogeneity of symptoms. Theoretical and practical implications are discussed, as well as the need for further research.     

Effects of a Genetic Counseling Model on Mothers of Children with Down Syndrome: A Brazilian Pilot Study

Down syndrome occurs in approximately 1:600 live births. Genetic counseling is indicated for these families and may be beneficial for adaptation to the challenges that accompany by this diagnosis. Although the basic counseling goals are similar, there are many models of genetic counseling practiced around the world. The aim of this article is to report the results of a pilot study that evaluated the level of satisfaction with a model of service delivery of genetic counseling practiced in Brazil, the knowledge assimilated about Down syndrome and whether this process resulted in a feeling of well-being and psychological support. Thirty mothers of under 6-month-old children with Down syndrome were interviewed after having two sessions of genetic counseling in a public healthcare service within a period of 30 days. A semi-structured questionnaire was developed by the researchers to collect identification, socioeconomic and demographic data and to assess the client’s satisfaction with the model of genetic counseling. Data were collected using both open and closed questions. The reported level of satisfaction was high. The knowledge assimilated about Down syndrome after only two sessions was considered technically vague by raters in 44 % of cases. Most mothers (96.7 %) reported that genetic counseling was beneficial and provided psychological support. The model was considered satisfactory, but further research is needed to identify ways to improve knowledge retention by this population. These results highlight the utility of referring families for genetic counseling when there is a suspicion of a diagnosis of Down syndrome.     

Anxiety, Sensory Over-Responsivity, and Gastrointestinal Problems in Children with Autism Spectrum Disorders

Children with autism spectrum disorders (ASD) experience high rates of anxiety, sensory processing problems, and gastrointestinal (GI) problems; however, the associations among these symptoms in children with ASD have not been previously examined. The current study examined bivariate and multivariate relations among anxiety, sensory over-responsivity, and chronic GI problems in a sample of 2,973 children with ASD enrolled in the Autism Treatment Network (ages 2–17 years, 81.6 % male). Twenty-four percent of the sample experienced at least one type of chronic GI problem (constipation, abdominal pain, bloating, diarrhea, and/or nausea lasting three or more months). Children with each type of GI problem had significantly higher rates of both anxiety and sensory over-responsivity. Sensory over-responsivity and anxiety were highly associated, and each provided unique contributions to the prediction of chronic GI problems in logistic regression analyses. The results indicate that anxiety, sensory over-responsivity and GI problems are possibly interrelated phenomenon for children with ASD, and may have common underlying mechanisms.
