Findings indicated that (1) when siblings were 24-months-old, their social-emotional behavior displayed some concordance, and maternal behavior was stable with all siblings; (2) significant concordance in siblings' social-emotional behavior was conditioned by stability of maternal behavior; and (3) quality of infant-mother attachment at 12 months…

Previously published data on infants aged 12 and 13 months who were observed in the Strange Situation with their mothers and fathers were reanalyzed using a component process approach. (PCB)

Characteristic patterns of infant-parent relationships were examined in a sample of Black infants presumed to be at low risk for psychopathological development. Infant responses toward parents and a stranger in a structured laboratory play session were analyzed to determine normative patterns of Black infant-parent attachments. Infant exploratory…

This article outlines a strategy for studying early social relationships in relatively simple animal model systems. It describes some of the differences in approach between neuroscientists and human developmentalists in dealing with the same research problems. (BN)

This paper outlines several properties of internal representational models (IRMs) and offers terminology that may help to differentiate the models. Properties of IRMs include focus, memory systems, content, cognitive function, "metastructure," quality of attachment, behavioral strategies, and attitude toward attachment. An IRM focuses on…

Discusses observations of sets of infant twins, aged 6 to 24 months, as they interacted with one another and with an unfamiliar peer. Assesses quality of infant-mother attachment. Finds twins are more likely to react with one another than with a peer. Results are discussed in relation to early peer relationships and attachment. (Author/RWB)

But within that common background, men tend to marry women slightly below themselves, a phenomenon known in sociology as the marriage gradient. To determine the extent to which students are comfortable with unequal relationships and traditional and…

Four studies involving 40 pigtail monkeys are described in which relatively short separation experiences in infancy were associated with evidence of persistent changes in social behavioral function (less sociability, fewer close friends) and immunological function (suppression of lymphocyte proliferation) up to 6 years later.
