Researchers have noted the need, particularly when working with young people, to examine positive processes of development and how they can be considered protective factors of child development under adverse conditions. This study aims to investigate whether high levels of hope and life satisfaction during childhood are associated with a reduced…

Individuation in relation to father and mother is one of the key developmental tasks of adolescence, and has been conceptualized as gaining autonomy while maintaining relatedness to parents. Research on high-conflict, divorced and step-families suggests that specific stressors in these family types may compromise successful individuation by…

In this paper, we review findings from Project Competence on the nature of personality development from middle childhood through the early adult years and place these findings in the context of current research on temperament and personality traits. In a series of studies using data drawn from the Project Competence longitudinal project, we have…

Analysis of 65 children over a 4-year period on tests of operational and causal thinking offers support for Piaget's notion of stage progression. In kindergarten and grade one, the majority of children in this longitudinal study were between preoperational and the achievement stage of operational thought. By grade two, the majority had attained…

This longitudinal study investigated the relationship of stress arising from medical problems of newborns to parent-infant interaction through the infant's first year. Significant interactive differences between full term and premature infants were found in feeding situations during the neonatal period and in floor play at eight months. The sample…

In this study an attempt was made to obtain a developmental dimension for estimating longitudinal development on the basis of cross-sectional data. To check the validity of this approach, the cross-sectional data were compared with true longitudinal data. Forty-three public school children were given a series of conservation tasks in four…
