This commentary on Livingstone and Smith (2014) suggests that more attention should be paid to a set of hypotheses about technology that contrasts with those that have animated much of the current research interest: (a) That the digital environment is no more perilous and perhaps less perilous than other offline environments youth inhabit; (b)…

Psychologists and psychiatrists have long been aware that individuals differ in their response to environmental stressors. It is equally apparent that whilst positive or corrective environmental factors help some individuals, others seem to benefit little, if at all. To make the matters even more interesting (at least for a researcher who is…

There have long been suggestions that reduced levels of empathy are associated with an increased risk for antisocial behavior (e.g., Miller & Eisenberg, 1988). The article by Rhee and colleagues on typically developing children (Rhee et al., 2012) is important because it is one of the few studies to longitudinally examine the relationship…

In the current issue of this journal, Rapee (2013) reports that the incidence of internalizing disorders was reduced as a result of a brief parent centered intervention amongst adolescents who as young children were characterized with the temperament of behavioral inhibition (BI). The intervention was administered when children were 3 to 5 years…

In this commentary, Martin Holtmann, discusses Doehnert and colleagues' article in this issue (Doehnert et al., 2013). Holtmann comments that the article illustrates the value of longitudinal electrophysiological and experimental approaches to disentangle different pathways underlying the phenotype of ADHD, and points out that their…

Many researchers have attempted to uncover the precise contribution of fathers to childrearing in relation to both young and older children's development during the past five decades (Lamb, 1975), including during the infancy period (Parke & O'Leary. S, 1975). However, few have been able to isolate precise mechanisms by which specific types of…

In their analysis of the accumulated data from the clinically ascertained Simons Simplex Collection (SSC), Hus et al. (2013) provide a large-scale clinical replication of previously reported associations (see Constantino, Hudziak & Todd, 2003) between quantitative autistic traits [as measured by the Social Responsiveness Scale (SRS)] and…

The Social Responsiveness Scale (SRS) is currently being used in clinical and genetic studies of autism as both a screener and as a quantitative measure of autistic traits. This article assesses the influence of nonspecific factors on SRS scores to aid researchers in their interpretations of these scores. In their commentary, Constantino and…

This randomized clinical trial of methylphenidate in children with intellectual disability (ID) by Simonoff et al. (2013) advances the field in several ways useful to clinicians. The large ("N" = 122) widely representative sample more definitively confirms findings previously reported from smaller studies and studies with a differently…

The commentary by Arnold (2013) raises a number of interesting issues and speculations about the action of methylphenidate in children with intellectual disability (ID) and associated neurodevelopmental disorders, such as autism spectrum disorders. In our article (Simonoff et al., 2013), we were careful to stick closely to the statistical analysis…

Children with Specific Language Impairment (SLI) find it effortful to learn to talk and these difficulties can be persistent. Given the importance of language to human behaviour, it is not surprising to find that language difficulties are a risk factor for associated difficulties in other aspects of children's development. This article asks…

The preceding article by Hawton and colleagues reporting on a prospective study of adolescents presenting with self-harm to Accident and Emergency departments (A&E) is one of the largest epidemiological studies to examine the long-term outcomes of self-harm in children and adolescents. After a median of 6 years nearly 30% re-presented to A&E with…

Most people have 23 pairs of chromosomes; one set from the mother and one from the father. However, nondisjunction errors during meiosis can lead to a case of trisomy, where there are three rather than two chromosomes. Although such events are not uncommon, they are usually lethal, and account for a high proportion of spontaneous abortions. There…

Impairments in social communication are the core diagnostic features of autism spectrum disorders (ASD). In the past two decades findings from important clinical research studies have translated into improvements in understanding and practice, for example leading to a reduction in the age at which autism is commonly first recognised and diagnosed…

The last 50 years have witnessed enormous strides in the measurement and classification of child and adolescent psychiatric disorders. Debates about whether we should continue to depend upon a categorical nosology still continue, but we argue that, despite the absence of clear dividing lines between psychiatric disorders and normality and ubiquity…
