In this short contribution I introduce myself to the readership of the "International Journal of Developmental Science" by describing some high points in my scientific career, leading up to a major change in my perspective on the proper way to conduct empirical research in developmental science.

What we're thinking about behaviorally challenging students and what we're doing to them requires a fresh look. When schools believe that parental discipline explains a child's misbehavior, educators are less likely to consider different explanations for the misbehavior and the full range of interventions that could be implemented at school. And…

In addition to his pioneering studies on prenatal development of social responses in the mallard, Gilbert Gottlieb made important theoretical contributions to the study of the evolution of behavior. This tribute to Gottlieb presents his early view that prenatal behavioral development is the product of evolution and his revision of this view in his…

The process of making meaning is a core determinant of human experience. Understanding this process, developmentally, is a vital part of integral counseling. In this article, the authors introduce the concept of ego development stages as increasingly complex and flexible systems of meaning making. An understanding of ego development stages can…

Gottlieb used naturalistic observations of normally occurring events in the life history of individuals for the purpose of discovering the role of experience in the development of species-typical behaviors. His research revealed the impact of self-generated experiences (particularly those experiences that were self-stimulated) in the establishment…

Gilbert Gottlieb's formative role in establishing a science of experimental behavioral embryology is described. His experimental program on the development of species identification served as a model for developmental psychobiologists seeking alternatives to the nature-nurture dichotomies prevalent in the 20th century. Two of the major concepts…

Describes a project-based situation in mathematics with 12- and 13-year-old students in 2 schools in Edinburgh, Scotland. The main theme of the project, its results, and afterthoughts are presented to illustrate differences in the behavior and attitudes between students in the last year of primary school and those in the first year of secondary…

Discusses five Montessori insights about children's development as they relate to family and school life: independence and autonomy, community and socialization, interest in culture and morality, preadolescents' apprenticeship for adulthood, and adult acceptance of the evidence of change. Notes that underlying dynamics of home and school are alike…

Three case histories elucidate a discussion of the developmental nature of the behaviors of juvenile male sexual offenders. The sexual assault cycle is defined in the stages of negative self-image, predicting rejection, isolation, fantasies, planning the offense, and committing the offense. Tools for treating the offender are outlined. (Author/JDD)

One of the most important skills of professionals who work with young children is the ability to assess developmental functioning through informal observation. This skill serves as the foundation for screening or identifying children in need of developmental services, conducting play-based developmental assessments, and helping parents to…

This article defines, provides a rationale for, and describes the implementation of a classroom management level system in a middle school program for students with severe behavior disorders. The system is a motivational plan for behavioral improvement based upon a graduated series of levels with increasing student responsibility and privileges.…

Notes that "Loveys," or transitional comfort objects, are an important prop in some children's emotional and intellectual development. Provides developmental information, and describes types of children who typically use loveys, challenges to child care programs when the object comes to school, and how children give up their attachments.…

For the individual, gender difference falls along the feminine-masculine continuum with strong neurodevelopmental influences at various points throughout the lifespan. Neurodevelopmental influences are conceptualized in a vector model of sex difference. Vector attributes, direction and magnitude, are influenced initially by differences in levels…

Describes a classroom management approach called developmental discipline that incorporates observation with knowledge of the individual child, situation, and child development to guide appropriate behavior. Discusses factors associated with behavior problems and how teachers can work with parents to apply developmental discipline techniques and…
