Data showed that the majority of low-birth-weight twins and singletons had secure attachments, indicating that the propensity to form a secure attachment is a very robust phenomenon. Twinship did not affect infants' attachment classification. Contrary to the prediction that mothers in the insecure group would consistently obtain lowest ratings,…

Findings suggest that infant temperament affects the manner in which security or insecurity is expressed, but does not determine whether an infant develops a secure or insecure attachment to parent. (PCB)

This article attempts to illustrate the value of a psychobiological approach to the study of a particular behavior; in this case, vocalization of infant primates following loss of the mother. (PCB)

No differences were found in mother-infant attachment between nonadopted and intraracial adopted subjects or between intraracial and interracial adopted subjects. Suggests that the higher incidence of psychological problems found among adoptees in middle childhood and adolescence cannot be explained in terms of insecure attachment relationships…

Results suggest that various aspects of Strange Situation behavior are related to both maternal and infant temperament, and that maternal temperament is a predictor of attachment security, particularly for Type A mother-avoidant infants. (Author/RH)

Results from this study of 110 low-risk, middle-class infants showed that a significantly greater proportion of infants whose mothers worked full-time outside the home were assigned to the category "insecure-avoidant" than infants whose mothers remained in the home throughout their children's first year of life. (PCB)

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)

Examines child's representation of self in connection with child-mother attachment in a sample of 52 white, middle-class children aged six years. Results indicate that significant, albeit modest, connections between attachment and the self were established; further, specific patterns of self-perceptions were related to particular patterns of…

The role played by neuroembryological forces in shaping brain development is well documented in Nowakowski's (1987) article. Additional mechanisms whereby experience may influence brain structure and function are outlined. Several routes exist by which postnatal experiential influences may produce long-term alterations in behavior and…

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…

Examines 2,000 Strange Situation classifications obtained in eight different countries. Differences and similarities between distributions in classifications of samples are investigated using correspondence analysis. Substantial intracultural differences are established; data also suggest a pattern of cross-cultural differences. (Author/RWB)

The relation between resumption of full-time employment by mothers of infants, and subsequent infant-mother and infant-father attachments, was examined. No relation emerged between maternal work status and the quality of infants' attachments to their mothers. (PCB)

Classifications of the quality of infant-mother and infant-father attachments were made for 59 children at 12 and 20 months of age using the Ainsworth strange situation paradigm. Stability of attachments from 12 to 20 months was examined in four groups defined by maternal employment status. (Author/RH)

Findings indicated that attachment-related affect may reflect an affect continuum that underlies certain mother- and stranger-directed behaviors in the Strange Situation. However, not all aspects of reunion behavior can be predicted by prior separation reactions. (Author/RH)

Infants whose mothers were supportive of their autonomy displayed greater task-oriented persistence and competence during play than did infants of more controlling mothers; securely attached and avoidant infants tended to exhibit greater persistence at tasks than anxious-ambivalent babies, and ambivalent babies were the most negative in affect.…
