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.     

Joint Attention and Attachment in Toddlers with Autism

Joint attention is often referred to as a triadic relation between self, other and object. Young children with autism show deficiencies in the use of joint attention behaviors. Individual differences may be expected, and they may be determined by the children’s cognitive development or the characteristics of the relationship of the child with the caregiver. Although most joint attention skills develop under the age of three, most studies of joint attention in children with autism involved children older than 3 years of age, due to difficulties in diagnosing autism under this age. In this study we investigated joint attention behaviors of 78 young children (mean age 25.7 months, SD 6.1) with autism spectrum disorders (n = 20), other developmental delays (n = 18), and typically developing children (n = 40). Following the pertinent literature and confirmed by factor analysis, two types of joint attention behaviors were distinguished, Basic Joint Attention (BJA) and Associated Joint Attention (AJA). We found that cognitive delays and autistic symptoms—but not attachment insecurity or disorganization—were related to less joint attention. Already at the age of 2 years, children with more autistic symptoms show less joint attention, even after controlling for developmental level.     

Gestural overlap in consonant clusters: effects on the fluent speech of stuttering and non-stuttering subjects

This study was designed to investigate if persons who stutter differ from persons who do not stutter in the coproduction of different types of consonant clusters, as measured in the number of dysfluencies and incorrect speech productions, in speech reaction times and in word durations. Based on the Gestural Phonology Model of Browman and Goldstein, two types of consonant clusters were formed: homorganic and heterorganic clusters, both intra-syllabic (CVCC) and inter-syllabic (CVC#CVC). Overall, the results indicated that homorganic clusters elicited more incorrect speech productions and longer reaction times than the heterorganic clusters, but there was no difference between the homorganic and the heterorganic clusters in the word duration data. Persons who stutter showed a higher percentage dysfluencies and a higher percentage incorrect speech productions than PWNS but there were no main group effects in reaction times and word durations. However, there was a significant three-way interaction effect between group, cluster type and cluster place: homorganic clusters elicited longer reaction times than heterorganic clusters, but only in the inter-syllabic condition and only for persons who stutter. These results suggest that the production of two consonants with the same place of articulation across a syllable boundary puts higher demands on motor planning and/or initiation than producing the same cluster at the end of a syllable, in particular for PWS. The findings are discussed in light of current theories on speech motor control in stuttering. EDUCATIONAL OBJECTIVES: The reader will be able to describe: (1) the effect of gestural overlap between consonant clusters on speech reaction time and word duration of people who do and do not stutter and be able to (2) identify the literature in the field of gestural overlap between consonant clusters.     

A cross-cultural, long-term outcome evaluation of the ISTAR Comprehensive Stuttering Program across Dutch and Canadian adults who stutter

There is a need to evaluate the effectiveness of stuttering treatment programs delivered in domestic and international contexts and to determine if treatment delivered internationally is culturally sensitive. Evaluation of the effectiveness of the ISTAR Comprehensive Stuttering Program (CSP) within and across client groups from the Netherlands and Canada revealed generally positive results. At 2 years post-treatment both groups were maintaining statistically significant reductions in stuttering frequency and improvements in attitudes, confidence, and perceptions as measured by the Revised Communication Attitude Inventory (S24), Perceptions of Stuttering Inventory (PSI), and the approach scale of the Self-Efficacy Scaling by Adult Stutterers (SESAS). Data pooled across the groups on these measures gave evidence of a global treatment effect with standardized effect sizes ranging from typical to larger than typical in the behavioural sciences. Only two differences between the groups emerged: differences in speech rate and perception of self. Given that these groups represent two distinct cultures, differences were discussed in terms of whether they could be due to cultural, methodological, or other variables. Overall, results suggest that, the CSP appears to be similarly effective in both cultures and thus, sufficiently sensitive to the culture of Dutch adults who stutter.

Educational objectives: The reader will be able to (a) describe a methodology that can be used in a clinical setting to evaluate the long-term effectiveness of stuttering treatment with adults, (b) describe some of the challenges in developing a model of clinically meaningful outcome, (c) explain the rationale for the need for cross-cultural investigations of treatment outcome, and (d) summarize speech and self-report results of the cross-cultural evaluation of an integrated stuttering treatment program.     

The costs of doing two things at once for young and older adults: talking while walking,finger tapping,and ignoring speech or noise

Young and older adults provided language samples in response to questions while walking, finger tapping, and ignoring speech or noise. The language samples were scored on 3 dimensions: fluency, complexity, and content. The hypothesis that working memory limitations affect speech production by older adults was tested by comparing baseline samples with those produced while the participants were performing the concurrent tasks. There were baseline differences: Older adults' speech was less fluent and less complex than young adults' speech. Young adults adopted a different strategy in response to the dual-task demands than older adults: They reduced sentence length and grammatical complexity. In contrast, older adults shifted to a reduced speech rate in the dual-task conditions.     

Song copying by humpback whales: themes and variations

Male humpback whales (Megaptera novaeangliae) produce long, structured sequences of sound underwater, commonly called songs. Humpbacks progressively modify their songs over time in ways that suggest that individuals are copying song elements that they hear being used by other singers. Little is known about the factors that determine how whales learn from their auditory experiences. Song learning in birds is better understood and appears to be constrained by stable core attributes such as species-specific sound repertoires and song syntax. To clarify whether similar constraints exist for song learning by humpbacks, we analyzed changes over 14 years in the sounds used by humpback whales singing in Hawaiian waters. We found that although the properties of individual sounds within songs are quite variable over time, the overall distribution of certain acoustic features within the repertoire appears to be stable. In particular, our findings suggest that species-specific constraints on temporal features of song sounds determine song form, whereas spectral variability allows whales to flexibly adapt song elements.Electronic Supplementary Material Supplementary material is available for this article at .     

Political Obligation,Dirty Hands and Torture; A Moral Evaluation

The example of a political leader who has to decide whether he would allow the torture of a suspect in order to get information about a ticking bomb has become notorious in ethical discussions concerning the tension between moral principles and political necessity. The relation between these notions must be made as clear as possible before a sincere moral evaluation of ticking bomb situations can be given. The first section of this article considers whether the concept of political obligation is different from moral and legal obligations or whether it is a special kind of moral obligation. In the second section, the idea that the dirty hands problem confronts us with the ambiguities of moral life is rejected because it would imply an untenable moral paradox. The thesis that is developed is, namely, if there is such a thing as political necessity, it must be some form of moral obligation. The third section analyses the concept of political necessity and concludes that it cannot overrule basic moral principles and that the international legal prohibition of torture must be considered to be a categorical imperative. In the last section, these ideas concerning political and moral necessity are brought in against the defence of torture, which should be tolerated in the ‘War on Terror’. There it will be argued that the use of the ticking bomb argument not only supports a highly hypocrite political practice but is also deceptive as a moral and political argument.     

Extending Corporate Social Responsibility Research to the Human Resource Management and Organizational Behavior Domains: A Look to the Future

Although issues of corporate social responsibility (CSR) have become an important topic of research, there have been few studies on this topic conducted in the fields of human resource (HR) management and organizational behavior (OB). To address this gap, we edited a special issue of Personnel Psychology that explicitly focuses attention on CSR in the HR/OB domains. In this introductory editorial, we synthesize and extend the four articles published in the special issue. We also address issues relating to the conceptualization and measurement of CSR, the application of microlevel theories to CSR, and the practical and methodological implications of research in this domain. Finally, we provide suggestions for future research linking CSR with some of the most frequently studied topics in HR/OB. We propose that a focus on HR/OB will improve our understanding of the antecedents and consequences of CSR and also benefit HR/OB in terms of bridging the science–practice and micro–macro gaps.
