This study of the stability of parent behaviors toward toddlers over a 3-week period used both aggregated and nonaggregated data. Comparison of stability correlations indicated higher stabilities for aggregated scores, with the level of stability increasing as scores from additional single sessions were aggregated. (PCB)

Discusses implications of a study of middle-class infants seen in the Ainsworth strange situation at 12.5 and 19.5 months; the investigation produced results inconsistent with the corpus of previous findings. (Author/RH)

Focuses on systems theory as the paradigm underlying family therapy and considers the implications of this framework for conceptions of the individual, the study of parent-child interaction, and new research formulations and areas of study. Considers trends in the developmental field that move toward such formulations. (RH)

Asserts (1) that contrary to Waters, findings affirm the importance of viewing mother-infant attachment as a dynamic relationship, responsive to family conditions, and (2) that these findings are consistent with those of other researchers. (Author/RH)

Multiple discriminant function analysis was conducted with data from Strange Situations. Results enable researchers to obtain attachment classifications directly from scores on interactive behavior and crying during reunion episodes. (PCB)

Suggests that designing home-based interventions as longitudinal development research (rather than outcome evaluation) can provide valuable knowledge about ecological factors that affect the development of competence in parents and children and about effective ways to support families. (Author/MP)

Notes that Rothbaum et al. (2001) integrate more than 200 studies conducted in 2 countries over 4 stages of development. Maintains that their method of integrating studies provides a promising way to overcome some of the most vexing methodological difficulties of cross-cultural research. (Author/KB)

Suggests that dominance can be defined as asymmetry in predictability in social variables of importance, and bidirectionality as symmetrical predictability. Procedures which address the concepts of cyclicity within a person and synchronicity between people and which assess asymmetry and symmetry in social interaction are discussed. (Author/RH)
