In recent years, the research on teasing and bullying has grown dramatically and is coupled with a rise in the development of intervention programs targeted to teachers, principals, and parents. Ultimately the goal of these programs is to reduce or eliminate teasing and bullying within school settings. The aim of this project is to clarify how…

The authors used a dynamic systems theoretical approach to examine intraindividual variability in emotional responses during the transitional period of adolescence. Longitudinal diary data were collected regarding conflicts between 17 teenage girls and their mothers over a period of a year. The results revealed a reversed u-shaped relation between…

This study investigates whether preschool-aged children show consistent patterns of behaviour in conflicts with their siblings. Consistency was assessed at the nomothetic (i.e., group), idiographic (i.e., individual), and idiosyncratic (i.e., consistent patterns that differed from the norm) levels. We examined conflicts between 19 2-year-old and…

Research has supported the existence of distinct behavioral patterns, demographic correlates, and etiologic mechanisms for aggressive (AGG) versus nonaggressive but delinquent (DEL) antisocial behavior. Though behavioral genetic studies have the potential to further crystallize these dimensions, inconsistent results have limited their…

Data from 154 interviews with students in grades 3 to 13 were analyzed to suggest a developmental progression of conceptual understanding associated with the sample space for two ordinary six-sided dice tossed simultaneously. The model was then considered in the light of responses to an extension task involving three six-sided dice with four sides…

During two decades of observing and leading middle school choral rehearsals, the author has observed that teachers frequently repeat exactly the warm-ups they present to their young adolescent choirs at every rehearsal. If teachers know one thing about middle school students, they know that they are constantly changing--physically, intellectually,…

Infant sleep is a major source of concern for many parents. The aims of this longitudinal study were to assess: (a) the development of sleep patterns among infants, (b) the development of maternal cognitions regarding infant sleep, and (c) the relations between these domains during the 1st year of life. Eighty-five mothers were recruited during…

During childhood and adolescence, increases in heritability and decreases in shared environmental influences have typically been found for cognitive abilities. A sample of more than 2,500 pairs of twins from the Twins Early Development Study was used to investigate whether a similar pattern would be found for science performance from 9 to 12…

According to Piaget, 5- or 6-year-old children gradually acquire the concept of time based on events (Piaget, 1969). In his experiment of investigating children's time concepts, Piaget found that children of these ages were able to place pictures based on sequential events with some errors; the younger children made more errors. The National…

A connection between servant leadership and constructive developmental theory is proposed. A theoretical framework is offered that examines the subject and object relationship for servant leaders at progressive stages of meaning making, showing how the way leaders make meaning of service evolves with their constructive development. The framework…

Over the past several years and to the delight of many child care center directors, the early childhood field has received funding to educate individuals working in child care classrooms to support professional development systems. However, not everyone receiving these educational opportunities to support their professional development embraces…

Researchers have hypothesized that over the life course, criminal offending varies with problems in other domains, including life failure and physical and mental health. To examine this issue, the authors use data from the Cambridge Study in Delinquent Development, a prospective longitudinal survey of 411 South London males first studied at age 8…

Traditionally early brain insult (EBI) has been considered to have better outcome than later injury, consistent with the notion that the young brain is flexible and able to reorganize. Recent research findings question this view, suggesting that EBI might lead to poorer outcome than brain insult at any other age. Exploring this early vulnerability…

Teaching sign language--to deaf or other children with special needs or to hearing children with hard-of-hearing family members--is not new. Teaching sign language to typically developing children has become increasingly popular since the publication of "Baby Signs"[R] (Goodwyn & Acredolo, 1996), now in its third edition. Attention to signing with…

Couples can improve their marriages by implementing relationship building skills they learn while participating in a marriage education program. This study addresses how marriages improved as a result of participating in the marriage education program, Married and Loving It![R] and what specific components of the learning experience facilitated…
