Callous-unemotional (CU) traits are associated with severe conduct problems (CP) in youth. Causal theories for CU traits focus on emotion processing deficits that interfere with empathy development. However, though CU traits are consistently associated with deficits in affective empathy (i.e., emotional reactivity), the association between CU…

Deviant behavior is detrimental to adolescents, and parental monitoring is necessary to forestall this act. Consequently, this study investigated the influence of parental monitoring on adolescents' deviant behavior as expressed by married adults in the Ilorin metropolis. This study also investigated moderating variables, including gender, age,…

Smith-Magenis syndrome (SMS) is a genetic syndrome most often caused by a deletion on chromosome 17 or more rarely by a mutation in the retinoic acid-induced 1 gene. The aim of this study was to investigate the Developmental Behavior Checklist (DBC) profile of persons with SMS and the associations between behavioural and emotional problems, age,…

Using a dataset involving 415 individuals with irritability, aggression, agitation and self-injury (IAAS) behaviors from the fragile X syndrome (FXS) FORWARD database, we describe the psychopharmacologic management of IAAS and features of the population of persons with FXS treated with drug therapy for IAAS. Among those with FXS exhibiting IAAS,…

Restricted interests are an established diagnostic symptom of autism spectrum disorder. While there is considerable evidence that these interests have maladaptive consequences, they also provide a range of benefits. This article introduces a new instrument, the Survey of Favorite Interests and Activities, and uses it to examine the nature of…

Basic perspective taking and mentalizing abilities develop in childhood, but recent studies indicate that the use of social perspective taking to guide decisions and actions has a prolonged development that continues throughout adolescence. Here, we aimed to replicate this research and investigate the hypotheses that individual differences in…

This study compared sibling interactions between 24-month-old children and their older sibling with ASD (high-risk; n = 24) with 24-month-old children and their typically developing older sibling (low-risk; n = 32). First, high-risk sibling pairs showed lower levels of positive behaviour and younger siblings of children with ASD imitated their…

Background: Behaviour problems are most common in people with intellectual disabilities. Nature of behaviour problems can vary depending upon the age, sex and intellectual level (IQ). Objectives: This study examined the distribution of behaviour problems across intellectual disability categories and their association with IQ age and sex in…

The school is a period of intensive development of the child, the child's socialization, creation and formation of attitudes, opinions and behavior patterns and others. During this period, the child comes in part from the protective environment of their parents and enters the world of social relations and interactions. Through interactions with…

The current study was a 7-year follow-up of 74 6-12 year old children with Pervasive Developmental Disorder-Not Otherwise Specified. We examined the rates and 7 year stability of comorbid psychiatric diagnoses as ascertained with the Diagnostic Interview Schedule for Children: Parent version at ages 6-12 and again at ages 12-20. Also, we examined…

Callous-unemotional (CU) behavior has been linked to behavior problems in children and adolescents. However, few studies have examined whether CU behavior in "early childhood" predicts behavior problems or CU behavior in "late childhood". This study examined whether indicators of CU behavior at ages 2-4 predicted aggression,…

This research examined whether following social and physical aggression trajectories across Grades 3-12 predicted psychological maladjustment. Teachers rated participants' (n = 287, 138 boys) aggressive behavior at the end of each school year. Following the 12th grade, psychosocial outcomes were measured: rule-breaking behaviors, internalizing…

Kindergarten retention is a popular practice for children who are considered unready for primary school. However, past research has not yet succeeded to find consistent, strong empirical evidence supporting the practice. In the current study, kindergarten repeaters' development in nine psychosocial domains is compared with that of equally at risk…

Daily living skills standard scores on the Vineland Adaptive Behavior Scales-2nd edition were examined in 417 adolescents from the Simons Simplex Collection. All participants had at least average intelligence and a diagnosis of autism spectrum disorder. Descriptive statistics and binary logistic regressions were used to examine the prevalence and…

Peace studies and peace education are multifaceted processes focusing on diverse audiences from children in elementary grades to those involved in political negotiations at the highest levels. This paper addresses the foundational importance of including conflict embedded in adult-child relationships in peace education. It conceptually grounds…
