Extinction of fear requires learning that anticipated aversive events no longer occur. Animal models reveal that sustained phosphorylation of the extracellular signal-regulated kinase (Erk) in hippocampal CA1 neurons plays an important role in this process. However, the key signals triggering and regulating the activity of Erk are not known. By…

Emotional support from classmates and teachers is a powerful protective factor in averting or reducing student mental health problems. Yet, longitudinal evidence indicates that there is decreased support from these groups as students advance to higher grade levels, a change that may be linked to diminishing mental health. This study followed 2,616…

Defeat and entrapment are psychological constructs that have played a central role in evolutionary accounts of depression. These concepts have since been implicated in theoretical accounts of anxiety disorders and suicidality. The current article reports on a systematic review of the existing research investigating the links among defeat,…

Background: The link between aggression and mental disorders has been the focus of diverse studies in persons with and without intellectual disabilities (ID). Because of discrepancies in the finding of studies in persons with ID to date, and because of differences in research design, instruments used and the population studied, more research is…

This article presents a review of the Children's Measure of Obsessive-Compulsive Symptoms (CMOCS), a self-report screening measure of obsessive and compulsive thoughts and behaviors in children and adolescents aged 8 through 19 years. Obsessive-compulsive disorder (OCD) is estimated to affect 1% to 3% of the population over their lifetime. The…

Background: Heightened error and conflict monitoring are considered central mechanisms in obsessive-compulsive disorder (OCD) and are associated with anterior cingulate cortex (ACC) function. Pediatric obsessive-compulsive patients provide an opportunity to investigate the development of this area and its associations with psychopathology.…

This waitlist-controlled study investigates the impact of a group-based cognitive-behavioral therapy with family involvement (CBT-F) on observed mother and child behaviors in children with obsessive-compulsive disorder (OCD). Forty-four children and adolescents with OCD and their mothers were observed during family discussions before and after…

Objective: Behavioral inhibition (BI) in early childhood is associated with increased risk for anxiety. The present research examines BI alongside family environment factors, specifically maternal negativity and overinvolvement, maternal anxiety, and mother-child attachment, with a view to providing a broader understanding of the development of…

Aim: The cognitive and psychiatric aspects of adult movement disorders are well established, but specific behavioural profiles for paediatric movement disorders have not been delineated. Knowledge of non-motor phenotypes may guide treatment and determine which symptoms are suggestive of a specific movement disorder and which indicate medication…

This book contains a compilation of papers presented at the International Psychological Applications Conference and Trends (InPACT) 2021, organized by the World Institute for Advanced Research and Science (W.I.A.R.S.), that this year has been converted into a fully Virtual Conference as a result of the ongoing Coronavirus (COVID 19) pandemic.…

Aims: To compare the usefulness of DSM IV and ICD-10 DCR criteria in clinic children presenting with the symptoms of inattention and hyperactivity-impulsivity. Methods: 62 children (54 boys and 8 girls) participated in the study. Children were assessed on Kiddie schedule for affective disorders and schizophrenia--present and lifetime version and…

The objective of the current study was to evaluate a proposed restrictive inattentive type of Attention Deficit Hyperactivity Disorder (ADHD) by comparing clinical correlates among youths with ADHD inattentive type (ADHD-I) as a function of the number of hyperactivity symptoms presented (none vs. 3 or less) and controls (individuals without ADHD).…

This paper outlines a way for thinking about continuity and change in childhood anxiety symptoms. Considerations for a model of continuity and change in anxious emotion are discussed first. Then, a perspective which may resolve inconsistencies across studies on the stability of childhood anxiety problems overtime is presented. The perspective…

Background: Little is known about changes in the prevalence of psychiatric disorders between childhood and adolescence, and adolescence and adulthood. Methods: We reviewed papers reporting prevalence rates of psychiatric disorders separately for childhood, adolescence, and early adulthood. Both longitudinal and cross-sectional papers published in…

Background: Anxiety disorders are often present at preschool age. Research on older children and studies contrasting preschoolers with high versus low behavioral inhibition (BI) highlight several risk factors, but these have not been investigated in community samples of young children. Child, parent, and peer factors at age 4 were therefore…
