Developmental dyscalculia is a learning disability that affects the acquisition of knowledge about numbers and arithmetic. It is widely assumed that numeracy is rooted on the "number sense", a core ability to grasp numerical quantities that humans share with other animals and deploy spontaneously at birth. To probe the links between number sense…

The early years of childhood are critical for optimal development of a variety of skills. The accurate and efficient identification of potential delays in, or issues with child development, is essential in identifying those children most in need of early intervention services. Screening procedures are designed to identify children who appear at…

This study investigated the childhood autism rating scale (CARS) as a tool for ASD diagnoses for 2-year-old (n = 376) and 4-year-old (n = 230) children referred for possible autism. The cut-off score to distinguish autistic disorder from PDD-NOS was 32 in the 2-year-old sample (consistent with Lord in "J Child Psychol Psychiatry Allied…

Behavioral insomnias of childhood (BIC) and sleep disordered breathing (SDB) disorders cause disrupted and/or inefficient sleep. Left untreated in early childhood, both conditions increase the risk of compromised development, particularly in the areas of behavior, cognition, and growth. This systematic review determined whether and how current…

Reports such as this typically begin with a statistic designed to highlight a problem. The girls and boys to whom this edition of "The State of the World's Children" is dedicated are not problems. Rather, each is a sister, brother or friend who has a favourite dish, song or game; a daughter or son with dreams and the desire to fulfil…

Purpose: Comparing children's skills across and within domains of development has become a standard in providing early intervention services. Profiling a child's strengths and challenges can help in making decisions regarding eligibility, diagnosis, and intervention. Profiling is particularly important for children who are not yet talking, due to…

Attention-deficit/hyperactivity disorder (ADHD) is a neuro-behavioural disorder that presents frequently in paediatric and mental health settings. Children with ADHD present with symptoms of hyperactivity, inattention, distractibility and impulsivity. The purpose of this paper is to provide clinicians with a summary of contemporary issues relevant…

Research on the language development of internationally adopted children has increased substantially in the past few years, with a variety of methods used to measure language abilities in this population, including parent and teacher reports, norm-referenced tests, conversational and narrative language samples, and other procedures. These…

The awareness and knowledge of developmental milestones among health practitioners need to be enhanced to better enable early identification and intervention with children who have delays in development, intellectual deficit, and developmental disabilities and are residents in low-and middle-income countries. To meet this end, a simple one-page…

When developmental concerns arise in children, a clinical assessment focuses on the child's developmental profile to achieve three goals (1) determine diagnosis, (2) develop interventions, and (3) evaluate progress. Parents often have needs during this time that are not addressed by professionals because of the exclusive focus on the child during…

As part of the Combating Autism Act of 2006, the members of the Interagency Autism Coordinating Committee (IACC) are required to develop an annual "Summary of Advances" to describe each year's top advances in autism spectrum disorder (ASD) research. These advances represent significant progress in the early diagnosis of ASD, understanding the…

Rich with clinical insights, this volume reviews the state of the science of identifying and treating autism spectrum disorders (ASD) in very young children. Leading authorities examine critical research issues and present innovative approaches to assessing social, cognitive, adaptive, communication, and sensory-motor impairments in the first two…

Presents the theoretical background for the concept of mastery motivation and describes three characteristics of mastery motivation in toddlers: behavioral manifestations in multiple domains, developmental changes in those manifestations, and the influence of the socializing environment. Implications for assessment of individual differences and…

Responding to disruptive or troubled pupils with emotional and behavioural difficulties (EBD) remains a highly topical issue. The challenges these children present relate to wider issues of continuing political concern: the perceived declining discipline in schools; school and social exclusion; the limits to inclusion for children with special…

The "Ages and Stages Questionnaires," a parent-completed developmental monitoring system, is described, and various strategies for using the system to identify young children with developmental delays are compared. Strategies include mail-out, home visit, on-site (completed by either parent with assistance from service provider),…
