Associations Between Positive Development in Late Adolescence and Social, Health, and Behavioral Outcomes in Young Adulthood

Little is known about positive development across the transition from adolescence to young adulthood. The purpose of this paper was to use longitudinal data from a large community sample, the Australian Temperament Project, to investigate prospective associations between positive development at age 19?C20?years and changes in social, health, and behavioral outcomes at 23?C24?years. Data from 890 young adults (61.7% women) were analyzed using path analysis. Emotional health, physical well-being, friendship quality, reduced antisocial behavior, and positive development in young adulthood were predicted by higher levels of positive development in late adolescence, after controlling for baseline levels of respective outcomes, gender, and family socioeconomic status. Parent relationship quality and alcohol use were not significantly predicted. Based on these findings, interventions promoting positive development during adolescence should be investigated as a potential means of yielding positive social, health, and behavioral consequences well into young adulthood.     

EFFECTS OF NONCONTINGENT MUSIC ON VOCAL STEREOTYPY AND TOY MANIPULATION IN CHILDREN WITH AUTISM SPECTRUM DISORDERS

Noncontingent music has been shown to reduce engagement in vocal stereotypy in children with autism spectrum disorders, but its effects on appropriate collateral behavior remain unknown. Given that noncontingent music is typically implemented during periods of free play, clinicians may be concerned with the effects of the intervention on toy manipulation. Thus, we examined the immediate and subsequent effects of noncontingent music on engagement in vocal stereotypy and toy manipulation in four children with autism spectrum disorders by using a three‐component multiple schedule combined with a multi‐element design. The results suggest that noncontingent music (i) reduced immediate engagement in vocal stereotypy for three of four participants, (ii) never increased subsequent engagement in vocal stereotypy, and (iii) produced idiosyncratic effects on immediate and subsequent engagement in toy manipulation for two participants. The clinical implications of the results are discussed in terms of improving the treatment of vocal stereotypy using noncontingent music. Copyright © 2012 John Wiley & Sons, Ltd.     

Putting families in the center: family perspectives on decision making and ADHD and implications for ADHD care

Objective: To examine components of family-centered care in families' stories about treatment decision making for their child with ADHD. Method: Twenty-eight families participated in qualitative interviews that addressed families' perspectives on (a) the treatment decision-making process, (b) the cause and impact of their child's symptoms, and (c) treatment goals and preferences. Results: The majority of families preferred to be primary or shared decision makers regarding treatment decisions. Families' perspectives on the cause of the child's symptoms varied and often were not consistent with a biomedical framework. Families described multiple areas of impairment on child, family relationships, and family functioning. Perspectives toward evidence-based treatments were mixed, with families also expressing interest in and pursuing interventions not delineated in current treatment guidelines. Conclusion: These findings reinforce the importance of eliciting families' perspectives and involving these important stakeholders in shared decision making as critical components of family-centered care for children with ADHD.     

Robert Ulanowicz and the Possibility of a Theology of Evolution

In A Third Window Robert Ulanowicz exposes the explanatory weaknesses of both classical and statistical methods in scientific inquiry. His book, however, does much more than that. While being completely grounded in empirical science, it also outlines a worldview, or a metaphysics, that renders intelligible the fact of chance and emergent novelty. Ulanowicz establishes his position by comparing his ??third window?? onto nature with two others conventional scientific approaches. The purpose of this essay is to point out the value of Ulanowicz??s approach for improving the quality of conversation between science and theology.     

Learning without representational change: development of numerical estimation in individuals with Williams syndrome

Experience engenders learning, but not all learning involves representational change. In this paper, we provide a dramatic case study of the distinction between learning and representational change. Specifically, we examined long‐ and short‐term changes in representations of numeric magnitudes by asking individuals with Williams syndrome (WS) and typically developing (TD) children to estimate the position of numbers on a number line. As with TD children, accuracy of WS children's numerical estimates improved with age (Experiment 1) and feedback (Experiment 2). Both long‐ and short‐term changes in estimates of WS individuals, however, followed an atypical developmental trajectory: as TD children gained in age and experience, increases in accuracy were accompanied by a logarithmic‐to‐linear shift in estimates of numerical magnitudes, whereas in WS individuals, accuracy increased but logarithmic estimation patterns persisted well into adulthood and after extensive training. These findings suggest that development of numerical estimation in WS is both arrested and atypical.     

Motor proficiency and emotional/behavioural disturbance in autism and Asperger's disorder: another piece of the neurological puzzle?

The relationship of motor proficiency with emotional/behavioural disturbance, autistic symptoms and communication disturbance was investigated in children diagnosed with autism and Asperger's disorder (AD). The Movement Assessment Battery for Children was used as a measure of motor impairment, and the Developmental Behavioural Checklist was used as a measure of emotional/behavioural disturbance in the following groups: AD (n?=?22), high functioning autism (HFA) (n?=?23), LFA (n?=?8) and typically developing children (n?=?20). The HFA group had more difficulty with motor items, such as ball skills and balance, than did the AD group. There were significant positive correlations between impairments in motor proficiency (in particular ball skills and balance) and emotional/behavioural disturbance, autistic symptoms and communication disturbance. These findings are consistent with the hypothesis that there are qualitative and quantitative differences in the motor profile between autism and AD. In addition, the association between motor proficiency impairment and emotional/behavioural disturbance in autism and AD emphasizes the importance for screening of co-occurring emotional/behavioural symptoms in individuals with motor difficulties. These findings have implications for the potential use of adjunct motor measures in the diagnosis and definition of autism spectrum disorders.     

Contributions of the striatum to learning, motivation, and performance: an associative account

It has long been recognized that the striatum is composed of distinct functional sub-units that are part of multiple cortico-striatal-thalamic circuits. Contemporary research has focused on the contribution of striatal sub-regions to three main phenomena: learning of associations between stimuli, actions and rewards; selection between competing response alternatives; and motivational modulation of motor behavior. Recent proposals have argued for a functional division of the striatum along these lines, attributing, for example, learning to one region and performance to another. Here, we consider empirical data from human and animal studies, as well as theoretical notions from both the psychological and computational literatures, and conclude that striatal sub-regions instead differ most clearly in terms of the associations being encoded in each region.
