The effort by developmental psychopathologists to understand the etiology of antisocial behavior has resulted in several significant findings. First, aggressive behavior is highly stable from early childhood into adolescence and adulthood. Second, parental factors including rearing practices and parental psychopathology, are correlated with childhood behavior problems. It was the aim of the present study to examine the correlates and stability of aggressive behavior in a sample of toddlers from low income families. Eight-nine mother-child dyads (52 boys and 37 girls) were observed in laboratory assessments when the child was 18- and 24-months old. Frequency and pervasiveness of aggression were coded from videotapes. Familial criminality, maternal depressive symptomatology, child noncompliance, and difficult child temperament were examined as contributors to the prediction of aggression in toddlers. Stability of aggression was moderate, especially for aggression occurring in low-stress situations. While there were few sex differences in the frequency and stability of aggression, there were marked differences in the correlates and predictors of aggression. Gender-specific, interactional models of the development of aggression are proposed.This study was supported by grants to Daniel Shaw and Joan Vondra from the following organizations within the University of Pittsburgh: the Mental Health Clinical Research Center for Affective Disorders, the Office of Child Development, the School of Education in conjunction with the Buhl Foundation, and the Faculty of Arts and Sciences. Portions of this paper were presented at the Meeting for the Society for Life History Research, Philadelphia, April 1992. The authors would like to acknowledge the contribution of Julie Alley, Jodi Chusta, and Kevin Cosley for their invaluable assistance in behavioral coding. Special thanks is given to the mothers and children who participated in this research.  相似文献

Current family therapy has as its basis the concept of the family as a system. Systems theory has developed a set of explanations that are frequently functional in nature; they are often applied as though they assume that within a system a common goal is worked towards as in biological systems. For example, the concept of homeostasis is used in much the same way as Cannon (1929) used it to describe the mechanisms of stability within biological systems such as body temperature regulation. Here all the components of the system co-operate to maintain body temperature within certain limits. This functional assumption of a common aim amongst components of a system to achieve balance should be compared with a pluralist systems analysis which does not assume such commonality of goals. For example, a pluralist analysis could highlight the conflict inherent amongst different subsystems when one subsystem has more power than the other. At a theoretical level it can be seen that family systems theory has restricted itself to a limited set of assumptions about the explanatory concepts it uses. An analysis of women's psychology which has emerged through the developments of feminist therapy can enrich the theory and practice of family therapists.  相似文献

Property     
This paper first reviews material dealing with the question of whether possession and related behaviours are innately determined or secondary. It is considered that the significance of property-related behaviour can best be understood by reference to its ontogenesis, and to the social context, and to the intentions of the actor. Some relevant material is reviewed, and it is proposed that some forms of acquisition and possession of property may be limited to societies with a high degree of role flexibility and mobility and have to do with the building and maintenance of self-respect.  相似文献
