Spatial categorization has a long history in the research of infant cognition and perception. Many conclusions are drawn from the approach wherein infants are habituated to examples of a spatial category X and then display an attention recovery (i.e., dishabituation) to a contrasting category Y. However, the distinction infants make between X and…

Two experiments investigated how preschoolers judge whether learning has occurred. Experiment 1 showed that 3- and 4-year-olds used an individual's ability to demonstrate knowledge to judge whether he/she had learned something, regardless of that individual's claim about whether he/she had learned. Experiment 2 considered whether children…

Given the centrality of both parent-child attachment and emotion regulation in children's development and adjustment, it is important to evaluate the relations between these constructs. This article discusses conceptual and empirical links between attachment and emotion regulation in middle childhood, highlights progress and challenges in the…

Contrary to the substantial amount of research on infant, preschool, adolescent, and adult attachment, middle childhood has long been neglected by the international attachment research community.

In this brief essay, I comment on the constellation of papers published in the current issue. I argue that it represents the new beginning of the new era for the journal, driven by several considerations. Among these, three are key. First, the collection of articles in this issue is explicitly concerned with the multivariate and multidisciplinary…

This practical book provides pre- and inservice teachers with an understanding of how math can be learned through play.

Teaching and learning are intricately linked to social and behavioral factors of human development, including cognition, motivation, social interaction, and communication. Psychological science can also provide key insights on effective instruction,…

Purpose: From a psycholinguistic perspective, the quality of the stored word form in the phonological input lexicon, as well as its effective retrieval from the phonological output lexicon, is of great importance in lexical processing. This study aimed at gaining a deeper understanding of (a)typical word form processing in primary school children.…

Otitis Media (OM) is an important global issue that can have a long-lasting impact on a child's life. There is no easy fix! For a family who has a child with OM, the ramifications can be short term and have minimal consequences, or they can be very complex and involve medical, educational, behavioural and wellbeing issues, and may even be…

Early intervention has been established as efficacious in addressing developmental delays in young children with autism spectrum disorder. Evidence that caregiver-implemented interventions are feasible and effective for young children with autism spectrum disorder is emerging, yet research suggests there are barriers to enrollment in clinical…

Prevention and amelioration of the myriad effects of toxic stress on child development is a significant public health concern. Scalable programmes to address this concern are lacking. Attachment Vitamins (AV) is a novel universal prevention programme for parents of young children that is trauma-informed and addresses toxic stress within a…

Children from low-income backgrounds are less likely to have economically successful role models and mentors in their own families and neighborhoods, and are more likely to spend time with media. In this article, Melissa Kearney and Phillip Levine review the theoretical and empirical evidence on how these external forces can influence children's…

Research Findings: Kindergarten Entry Assessments (KEAs) -- assessment tools used at the beginning of kindergarten to provide educators with a snapshot of children's readiness for school -- are increasingly being adopted by states across the country. The purpose of this study is to examine the implementation of North Carolina's KEA through…
