Children who observed a very generous adult model sharing, later shared more than those who observed a very stingy model. The effects of vicarious reinforcement on the amount shared, delivered by either the experimenter or the model alone, were also demonstrated. (Authors)

Describes recent attempts to integrate developmental perspectives in research involving infant and child psychopathology. Definitions are offered, and various methods to foster the growth of developmental psychopathology are presented. (Author/RH)

In a naturalistic behavioral stdy, it was found that prematures have significantly more endogenous smiling than full-term newborns. (Authors)

Recent reports using a classical behavior genetic research design in which twin data are combined with a measured characteristic of their shared family environment have made striking claims about estimating environmental influences on behavior with genetic effects controlled. Such claims are overstated for two related reasons. First, when a…

This study examined reactions of 1-year-olds and young 2-year-olds to being controlled by mothers. Mothers' supportive behavior predicted children's willing compliance. However, contrary to research with older children, defiance was also associated with variables linked to maternal competence, specifically, mothers' supportive behavior,…

Presents a description of a neonatal monitoring system and the studies used in its validation. (SDH)

An actometer is a modified self-winding calendar watch which records acceleration and deceleration of movements with a significant component" in the same plane as the face of the watch. Actometers tested in this study were not reliable. (Author/MB)

Reviews parent-child interaction studies, the major source of information about the socialization process of the child. Deals fully with observation studies--naturalistic observation and experimentally arranged interaction in the laboratory--but also draws on interview and questionnaire methods for comparison. (WY)

Study investigated the effects of a response-produced intense-noise stimulus (punishment) on the extinction of children's hitting behavior. (Author)

Results indicate that there is no simple relationship between type of observer present and children's aggressive responding following exposure to an aggressive model. (Authors)

Although dissociations in children's responses are sometimes about "getting it right" for an experimenter, they might also often reflect differences between conscious and subconscious processing that are not geared to correct performance. Research with adults also reveals many cases of dissociation, and adults can more easily be subjected to…
