Sleep problems of parents of typically developing children and parents of children with autism

Few researchers have investigated the relation of children's sleep problems to their parents' sleep problems. Children with autism have been reported to evidence greater sleep problems than do typically developing children (C. D. Hoffman, D. P. Sweeney, J. E. Gilliam, & M. C. Lopez-Wagner, 2006; P. G. William, L. L. Sears, & A. Allard, 2004). In the present study, parents (N = 106) of children independently diagnosed with autism (4-16 years of age; M= 8.20 years, SD = 2.69 years) reported greater sleep problems for themselves than did parents (N = 168) of typically developing children (4-15 years of age; M = 8.62 years, SD = 3.28 years). Children's sleep problems were related to parents' sleep problems for both groups; in the autism group, children's level of symptomatology was not related to their parents' sleep. The authors suggest areas for further research on the sleep problems of children and their parents, the potential interaction of these problems with children's symptomatic behavior, and the relations of these factors to child, parent, and family functioning.     

Political skill as neutralizer of felt accountability—job tension effects on job performance ratings: A longitudinal investigation

This study examined the effects of felt accountability, political skill, and job tension on job performance ratings. Specifically, we hypothesized that felt accountability would lead to higher (lower) job performance ratings when coupled with high (low) levels of political skill, and that these relationships would be mediated by job tension. Data were gathered at multiple times over a one-year period (i.e., baseline performance, attitudinal variables one month later, supervisor reports of subordinate performance six months and one year after baseline performance was measured). Strong support was shown for the total effects model, whereby political skill moderated felt accountability—job performance ratings, felt accountability—job tension, and job tension—job performance ratings relationships. However, more focused analyses demonstrated that political skill most strongly moderated the job tension—job performance ratings linkage. Implications, strengths and limitations, and directions for future research are provided.     

Mainland Chinese and Canadian adolescents’ judgments and reasoning about the fairness of democratic and other forms of government

This study examined the judgments and reasoning of adolescents (ages 12–19 years) from three sites in urban and rural China (n = 270) and in an urban Canadian comparison sample (n = 72), about the fairness of various forms of democratic and non-democratic government. Adolescents from both China and Canada preferred democratic forms of government, such as representative or direct democracy, to non-democratic systems, such as a meritocracy and an oligarchy of the wealthy, at all ages. Adolescents appealed to fundamental democratic principles, such as representation, voice, and majority rule, to justify their judgments. Similar age-related patterns in judgments and reasoning were found across cultures and across diverse settings within China.     

The double-anchoring theory of lightness perception: a comment on Bressan (2006)

Recently, a double-anchoring theory (DAT) of lightness perception was proposed (P. Bressan, 2006), which offers explanations for all the data explained by the original anchoring theory (A. Gilchrist et al., 1999), as well as a number of additional lightness phenomena. Consequently, DAT can account for an unprecedented range of empirical results, potentially explaining everything from the basic simultaneous contrast display to subtle variations of the Gelb effect. In this comment, the authors raised 4 concerns that demonstrate serious theoretical and empirical difficulties for DAT.     

Representation and execution of vocal motor programs for expert singing of tonal melodies

Three experiments were conducted to study motor programs used by expert singers to produce short tonal melodies. Each experiment involved a response-priming procedure in which singers prepared to sing a primary melody but on 50% of trials had to switch and sing a different (secondary) melody instead. In Experiment 1, secondary melodies in the same key as the primary melody were easier to produce than secondary melodies in a different key. Experiment 2 showed that it was the initial note rather than key per se that affected production of secondary melodies. In Experiment 3, secondary melodies involving exact transpositions were easier to sing than secondary melodies with a different contour than the primary melody. Also, switches between the keys of C and G were easier than those between C and E. Taken together, these results suggest that the initial note of a melody may be the most important element in the motor program, that key is represented in a hierarchical form, and that melodic contour is represented as a series of exact semitone offsets.     

Size and reversal learning in the beagle dog as a measure of executive function and inhibitory control in aging

Several studies converge on the idea that executive processes age earlier than other cognitive processes. As part of a larger effort to investigate age-related changes in executive processes in the dog, inhibitory control was measured in young, middle-aged, old, and senior dogs using size discrimination learning and reversal procedures. Compared to young and middle-aged dogs, old and senior dogs were impaired on both the initial learning of the size task and the reversal of original reward contingencies. Impaired performance in the two aged groups was characterized as a delay in learning the correct stimulus-reward contingencies and, among the senior dogs in particular, an increase in perseverative responding. These separate patterns of reversal impairments in the old and senior dogs may reflect different rates of aging in subregions of the frontal cortex.     

Bipolar disorder in children and adolescents

There is increased recognition that bipolar disorder has an early age of onset. The prevalence of bipolar disorder in prepubertal children has not been determined, however the prevalence in adolescence is approximately 1%. Bipolar disorder in children poses a diagnostic challenge since the symptoms may differ from those in late adolescence and adulthood. Comorbid disorders, such as attention-deficit/hyperactivity disorder, further complicate both the diagnosis and course of the disorder. There is increasing evidence of the chronicity and severity of this disorder in youths. Bipolar disorder significantly disrupts a child's psychosocial development including impairments in academic functioning, family functioning, and relationship with peers. Although this disorder has significant morbidity in children and adolescents, there is a paucity of controlled studies to assess the efficacy and safety of mood stabilizers in the treatment of this disorder in youths. The treatment literature consists largely of case studies, retrospective chart reviews, and open-label studies. There is a compelling need for double-blind, placebo-controlled trials to determine whether commonly used medications to treat this disorder are significantly superior to placebo. Since many children in clinical practice require more than one psychotropic medication to adequately manage this disorder, studies of combination treatments are warranted. This review will provide an overview of the literature of bipolar disorder in children and adolescents, including discussion of the prevalence, diagnosis, epidemiology, course of the illness, and treatment issues.     

Factor structure of the Wechsler Adult Intelligence Scale-III in schizophrenia

This report examines and compares the factor structure of the new edition of the Wechsler Adult Intelligence Scale (WAIS-III) in a sample of chronic schizophrenia and schizoaffective disorder outpatients (n = 120) and an age-matched sample of individuals drawn from the WAIS-III standardization sample (n = 200). Exploratory and confirmatory factor analyses similar to those reported by the developers of the scale suggested that a model of WAIS-III performance with correlated factors for verbal comprehension, perceptual organization, working memory, and processing speed fit the data from the schizophrenia sample as well as it fit the nonclinical comparison sample and fit the data from both samples better than alternative models.     

The Greensboro Child Response Initiative: A Trauma-Informed,Mental Health–Law Enforcement Model for Children Exposed to Violence

This article evaluates a trauma-informed, mental health–law enforcement intervention model called the Greensboro Child Response Initiative (CRI). CRI is a community-coordinated response to mitigate the development of traumatic stress symptoms in children exposed to violence, with the goals of decreasing mental health symptoms and other negative outcomes. Results from a quasi-experimental study indicated that caregivers appreciate the quick follow-up and support by CRI advocates and police reported seeing CRI as a critical component of their responses to calls for service related to families and children. Police line-ups and training provided by CRI increased levels of empathy and awareness of child trauma. Monthly stakeholder meetings promoted an informed victim response and increased communication and networking opportunities among community providers and law enforcement. Results suggest that CRI is a promising community-based early intervention, and implications and suggestions are provided for replicability.     

Does Coaching Matter? A Multilevel Model Linking Managerial Coaching Skill and Frequency to Sales Goal Attainment

Managerial coaching is a process of feedback provision, behavioral modeling, and goal setting with subordinates to improve their performance and address their personal challenges. Despite the popularity of coaching as a management practice, the impact of coaching on objective measures of performance remains unclear. To this end, we tested a multilevel model linking managerial coaching frequency and skill to the sales goal attainment of 1,246 sales representatives in 136 teams within a pharmaceuticals organization over a year. Managers’ coaching skill, which was evaluated in the context of a training exercise, was directly related to the annual sales goal attainment of the sales representatives that they supervised. This effect was partially mediated by team‐level role clarity, as predicted by feedback intervention theory and goal setting theory. In addition, coaching skill had a cross‐level moderating effect on the relationship between coaching frequency and sales goal attainment; coaching frequency had a negative effect on goal attainment when coaching skill was low. We discuss the implications of this finding for coaching research and practice. Overall, our results demonstrate the clear theoretical and practical importance of effective managerial coaching by drawing on multisource and multilevel measurements with a predictive design.
