Researchers from different disciplines (e.g., physiological, psychological, philosophical) have investigated motivation using multiple approaches. For example, in physiology (the scientific study of the normal function in living systems such as biology), researchers may use "electrical and chemical stimulation of the brain, the recording of…

This edition of "The State of the World's Children" report examines children, food and nutrition. It seeks to deepen understanding around the causes and consequences of children's malnutrition in all its forms and to highlight how governments, business, families and other stakeholders can best respond. Chapter 1 examines the changing…

Crosscutting concepts such as "scale, proportion, and quantity" are recognised by U.S. science standards as a potential vehicle for students to integrate their scientific and mathematical knowledge; yet, U.S. students and adults trail their international peers in scale and measurement estimation. Culturally based knowledge of scale such…

This paper examines how early childhood policy initiatives in the United Kingdom and internationally currently reflect neoliberal concerns with school readiness in the development of human capital and what diverse theoretical perspectives might offer. The focus is a project involving a group of early childhood academics from one university and a…

Designing instruments for children and youth that result in reliable and valid data requires consideration beyond calculating grade-level equivalence of the text. Very little methodological research has been conducted on the survey response processes of children and youth and there are no comprehensive guidelines informing instrument development…

Disagreements between theorists and their collaborators are as old as the field of psychology itself. The most well-known example of a professional relationship marked by diverging viewpoints in psychology is that of Sigmund Freud and Carl Jung. Theoretical disagreements between them were resolved by Jung's creation of a new theory. In this…

Larry Schaefer's history of civility is a succinct summary of the implicit and evolving definitions of civility over 2500 years of civilization. Beginning with the Romans and the root word "civitas," meaning the rights and duties of citizenship, civility appears in classical literature as integral to the roots of democracy in the context…

This commentary discusses the articles that comprise this special issue on attachment in middle childhood. Central to this discussion is the distinction between verbal, strategic, and conscious responses to questionnaires as compared to verbal and nonverbal, automatic and largely unconscious responses to interviews. Both methods have been…

Interpretations of Vygotsky's texts have generally focused on the intellectual aspects of children's development, including his theory of play. This article presents a reinterpretation of Vygotsky's theory of play and draws on this theory of art to include emotions as an important part of children's play. I will argue that in play, children's…

Infants perceive intonation contrasts early in development in contrast to lexical stress but similarly to lexical pitch accent. Previous studies have mostly focused on pitch height/direction contrasts; however, languages use a variety of pitch features to signal meaning, including differences in pitch timing. In this study, we investigate infants'…

Various theorists have argued for the importance of a developmental approach to studying typical development (Karmiloff-Smith, 1998; Lerner, 1996; Lerner & Hood, 1986; Masten & Cicchetti, 2010; Overton, 2014; Overton & Lerner, 2012, 2014), and there are reasons to believe that this issue is even more critical to the study of…

As individuals and adult educators we consistently face an array of what seem to be increasingly complex challenges. These run the gamut from battling poverty and illness with their deleterious and deadly effects, to acquiring literacy and workplace competencies and to building expertise in communication, collaboration and innovation. And we live…

Reading comprehension is based on the efficient accomplishment of several cognitive processes at the word, sentence, and text level. To the extent that each of these processes contributes to reading comprehension, it can cause reading difficulties if it is deficient. To identify individual sources of reading difficulties, tools are required that…

The origins and development of our geometric intuitions have been debated for millennia. The present study links children's developing intuitions about the properties of planar triangles to their developing abilities to read purely geometric maps. Six-year-old children are limited when navigating by maps that depict only the sides of a triangle in…

Previous research has found that when children engage in social and moral transgressions, they take steps to either remedy or explain their behavior. However, no prior systematic investigation has examined the strategies children employ to 'correct' their behavior in future situations. The present study employed a domain theory lens to investigate…
