For many children and their families, the period of time between Thanksgiving and the New Year is marked with great cheer, delicious home-cooked meals and exciting road trips to visit family and friends. But families affected by attention deficit disorder (ADD) can often miss out on the joys of the holiday season if the condition is not managed…

In this study we examined parent and teacher agreement at the item level of the newly revised Child Behavior Checklist/1??5 (CBCL/1??5) and Caregiver?Teacher Report Form/1??5 (CTRF/1??5) in 505 preschool children from low-income and predominantly African American families. Parents generally rated more children as having problem behaviors than did…

Mothers' emotion talk, children's emotion talk, and children's understanding of emotion were examined in 50 mother-child dyads at 41 months. Language measures included total emotion words, unique emotion words, labels, explanations, and different types of explanations. Children's emotion understanding was assessed for labeling, situation, and…

The aim of this article is to introduce readers to an alternative way of applying U-shaped functions to understand development, especially cognitive development. In classical developmental applications, age is the abscissa; that is, in the fundamental equation B = f(A), some behavioral variable (B) plots as a U-shaped or inverted U-shaped function…

The articles in this collection consider one very interesting puzzle of development: U-shaped developmental functions. At some point during development, an organism might exhibit what seems like a regression from its expected developmental trajectory and, according to continuity models of development, this is aberrant. In this special issue,…

Background: Associations between early mother-child mutually responsive orientation (MRO) and children's conscience have been previously established, but the mechanisms accounting for those links are not understood. We examined three such mediational mechanisms: (a) the child's enhanced enjoyment of interactions with the mother, (b) increased…

The occurrence of developmental regression in autism is one of the more puzzling features of this disorder. Although several studies have documented the validity of parental reports of regression using home videos, accumulating data suggest that most children who demonstrate regression also demonstrated previous, subtle, developmental differences.…

Early detection of developmental and behavioral/mental health problems is greatly facilitated when quality instruments are deployed. This article describes how to identify accurate measures and presents standards for screening tests. Included is a table delineating accurate tools for primary care: typically those relying on information from…

The types of non-maternal child care received by more than 1000 U.S. children were examined from birth to 54 months and related to family selection factors and to child outcomes. Individual children tended to experience a variety of different types of care and not to fit into clear patterns of either stable care types or progressive patterns of…

This is a report of an 11-year-old, prepubertal boy with acute-onset urinary urgency and frequency, obsessions and compulsions related to urination, severe mood lability, inattention, impulsivity, hyperactivity, and intermittent periods of immobilization. Fever, cough, otitis, and sinusitis preceded neuropsychiatric symptoms. Antistreptolysin O…

The skills, social impairments and challenging behaviours of a total population of 166 children, with severe intellectual disabilities and/or autism, were assessed through interview with the main carers, when the children were under 15 years old (time 1). Twelve years later, 141 of these individuals were re-assessed, using the same measures (time…

In this study, we investigated the relationships between rapid naming of letters, digits and colours, and reading ability and executive function. We gave fifty-six grade three and four children rapid automatised naming tasks using letters and digits as stimuli, executive function measures including the Stroop task, a working memory task and the…

Research has shown that self-evaluation can have positive effects on children's behavior and academic performance. Components of self-evaluation that have not been fully examined include the accuracy and sensitivity of students' ratings before and after training, as well as the effects of accuracy training on performance. Four students exhibiting…

A functional analysis was performed on a five-year-old nonverbal Autistic female with severe self-injurious behaviors. The self-injurious behaviors (hand-to-head, hand-to-jaw, hand-to-face) and loud vocalizations were targeted. Two types of sessions, enriched environment and instructor controlled preferred stimuli, were alternated throughout the…

A recent national survey on the expulsion of preschool children from child care centers reports that centers with access to mental health consultation have lower rates of expulsion than centers without access to classroom-based behavioral consultation. This article uses a series of vignettes from a composite case study to illustrate in…
