Peer rejection, temperament, and cortisol activity in preschoolers.

In this study, we examined a model that describes both direct and indirect pathways between children's temperament and activity of the hypothalamic-pituitary-adrenal (HPA) axis when children are in peer-group settings. We hypothesize that in peer-group settings both shy, inhibited and exuberant, undercontrolled children would exhibit higher cortisol levels, but these associations would operate through different pathways. Sociometric measures of peer rejection, salivary cortisol, and teacher reports of temperament were collected on 82 preschoolers.

Experimental studies of welfare reform and children.

Even prior to passage of federal welfare reform, many demonstration programs anticipated key features of the 1996 law, such as "work-first" strategies, time limits on welfare receipt, and financial incentives to work. Over the past decade, 10 experimental evaluations of these programs have extended their studies to examine the impacts on children. This article provides a synthesis of findings from the first seven of these studies to release results concerning child impacts.
