Children with conduct problems, irrespective of the(More)
A behaviorally-uninhibited temperament, callous-unemotional (CU) features, and harsh parenting have been associated with specific patterns of aggressive behavior in older children and adolescents.

On alternating days, adult male Long-Evans rats implanted with bilateral cannulas in the nucleus accumbens received intracerebral injections of testosterone in a water-soluble cyclodextrin inclusion complex (0.125, 0.25, or 0.5 microg/0.5 microl saline) or saline immediately prior to being confined for 30 min to 1 of 2 compartments of a place-preference(More)
This study investigated interactions between children's temperament and parenting styles in their association with measures of guilt and empathy. Participants were 87 predominantly Caucasian, middle-class mothers and their children between the ages of 3 and 5 (M = 4.39, SD = .51). Children nominated by their preschool teachers as being behaviorally(More)
