Background: The research reported in this article was commissioned by a consortium of inner-city schools located in central England. It was commissioned in response to the consortium's concerns regarding increasing referrals of negative pupil behaviour amongst its secondary school pupils in Key Stage 3 (ages 11-14), resulting in temporary and…

For pairs of full siblings, half-siblings, and cousins, analyzed maternal ratings of children's behavior problems at three times between ages 4 and 10. Found that nonshared environmental influences were substantial at each age but did not contribute to continuities in children's problem behaviors. Results favor a liability model that relates…

The conceptualizations of morphogenic processes suggested by systems theorists provide a useful framework for describing growth and development in complex adaptive self-directing organisms. These processes involve changes in (1) a system's structure, state, or functioning; (2) discontinuities in development; and (3) at least two kinds of…

Noting that humans develop according to a genetically encoded timeline and that departure from the timeline limits human potential, this book provides an illustrated practical guide to intervention to help children's bodies work as they should, to nurture children along their developmental timeline, to help children learn "from the inside…

This longitudinal study used repeated measures analysis of variance (RM ANOVA) and latent growth curve modeling to examine behavior change in 228 elementary school students over grades 1, 2, and 3 who varied in risk status. Of particular interest were the developmental trajectories for behaviors along four dimensions as rated yearly by teachers on…
