It has been 20 years since Bever's (1982) and Strauss and Stavy's (1982) books on U-shaped functions in human development were published. The three target articles in this issue describe several old and new U-shaped functions and new theoretical explanations for their existence. In this article, the authors will comment on two aspects of U-shaped…

Background: Debates about the developmental origins of adult face processing could be directly addressed if a clear infant neural marker could be identified. Previous research with infants remains open to criticism regarding the control stimuli employed. Methods: We recorded ERPs from adults and 3-month-old infants while they watched faces and…

Inagaki and Hatano (2002) have argued that young children initially understand biological phenomena in terms of vitalism, a mode of construal in which "life" or "life-force" is the central causal-explanatory concept. This study investigated the development of vitalistic reasoning in young children's concepts of life, the human body and death.…

We present findings based on several of our recent studies that have shown that father engagement has significant effects on children's cognition and language at 24 and 36 months and their social and emotional development at 24, 36 months, and pre-Kindergarten. These studies are guided by the Dynamics of Paternal Influences on Children over the…

Socioeconomic status (SES) is associated with childhood cognitive achievement. In previous research we found that this association shows neural specificity; specifically we found that groups of low and middle SES children differed disproportionately in perisylvian/language and prefrontal/executive abilities relative to other neurocognitive…

This year's "Report Card" breaks new ground by providing "The Children's Agenda", which details the top ten high-priority, high-impact actions California policymakers should take to reverse the declining status of children. It's clear any sound plan to revitalize the state must prioritize children's development. California's history backs this up,…

Filling a tremendous need, this is the first graduate-level child development text written specifically for future educators. The volume provides a solid understanding of major theories of development, focusing on how each has informed research and practice in educational contexts. Topics include the impact of biology and early experiences on the…

An instrument to measure teachers' instructional practices, the Instructional Practice Questionnaire, was developed and validated in three phases. The questionnaires focused on three domains of instructional practices: cognitive, interpersonal, and interpersonal. First, an initial questionnaire was developed for a pilot study, and data were…

Over the course of development, the ability to switch between different tasks on the basis of feedback cues increases profoundly, but the role of performance monitoring remains unclear. Heart rate indexes can provide critical information about how individuals monitor feedback cues indicating that performance should be adjusted. In this study,…

There is considerable interest in the potential non-musical cognitive and academic benefits of music listening and instruction to children. This report describes three lines of research relevant to this issue, namely, the effects of: (1) focused music listening on subsequent task performance (the Mozart effect); (2) music instruction; and (3)…

Background: Longitudinal pediatric neuroimaging studies have demonstrated increasing volumes of white matter and regionally-specific inverted U shaped developmental trajectories of gray matter volumes during childhood and adolescence. Studies of monozygotic and dyzygotic twins during this developmental period allow exploration of genetic and…

Cognitive impairment has long been associated with the natural history of HIV among vertically infected children. In children, HIV may have a direct or indirect impact on the developing brain, may lead to global or highly specific consequences, and may be responsible for minor cognitive consequences or, conversely, long-term and severe disability.…

This report summarizes findings from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development as effect sizes for exclusive maternal care and--for children in child care--type, quality, and quantity of care. Children (n = 1,261) were recruited at birth and assessed at 15, 24, 36, and 54 months.…

This paper discusses the relationship between Lev Vygotsky's zone of proximal development and cooperative learning. Vygotsky (1896-1934), a Russian psychologist, formulated a theory that children first develop lower mental functions such as simple perceptions, associative learning, and involuntary attention; then, through social interactions with…

The prevailing view of secrets as undesirable or unhealthy is challenged in this exploration of the meaning and significance of secrecy. As a crucial dimension of human development, secrets lead to a child's awareness of inner space and external worlds. This in turn leads to the development of a sense of self, personal responsibility, autonomy,…
