The general proposition of attachment theory is that attachment is grounded in an independent, biologically based system. The quality of primary attachment relationships strongly influences a child's early personality organization, particularly the concept of self and others. The theory emphasizes the primary status and biological function of…

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…

To assess the validity of attachment scores derived from the Ainsworth "strange situation", 56 1-year-olds and 79 2-year-olds accompaned by either the mother, the father, or a brief acquaintance were studied. Proximity to the adult, duration of play, crying, activity, and the incidence of looks and distance bids were measured. (Author/CS)

This study identifies elements in the attachment behaviors of 7-month infants which predict the quality of their attachment to their mothers at 13 months. At 7 months 147 infants were observed (and videotaped) during a free play period with their mothers present, during a separation from their mothers and then during a reunion period. At 13 months…

This longitudinal study of 10 infants in a day care nursery traces the development of recognition and attachment to a primary caregiver from approximately 3 1/2 months of age (shortly after enrollment in the program) through the end of the first year. Monthly assessments of about 10 minutes each, on two successive days, were made of the infant's…

Critically evaluates knowledge about relations between early interaction, the "strange situation," and later social behavior in normal and atypical infants including premature infants, abused or neglected infants, and the infants of depressed mothers. Attributes equivocal relations between early interaction behaviors and later attachment…

Social behaviors of 10- and 12-month-old infants were studied as a function of experimental context (home and laboratory) and experimental history (home rearing and day care). Results suggested that the experimental context influenced infant social behaviors. No differences attributable to rearing condition as a main effect were found. (Author/SB)

A twin analysis was applied to infants' social behavior in standardized situations that permitted the comparison of social responding to mother and a stranger in different contexts. Twenty-one identical twin pairs and twenty-five fraternal twin pairs were observed in their homes using time-sampled observations of specific behaviors. (Author/SS)

Customarily, several parent figures rear black infants. The effects of this practice on infant-parent attachments have not been studied even though they provide the chance to test the attachment theory contention that infants form a primary attachment when several attachment figures are available. To study this issue, 21 male and 16 female black…

The applicability of the Strange Situation procedure and the ABC typology for Japanese infants is discussed by examining data from studies in which the Strange Situation procedure was performed with Japanese infants. Findings of a study conducted in Sapporo, Japan, are discussed and their implications are pointed out. The discussion concludes that…

The purpose of this study was to investigate the relationship between infants' attachment to mother and mothers' responsiveness to behaviors of her infant. Twenty-four male and 24 female 12-month-old infants and their mothers were videotaped at a laboratory in the Ainsworth-Wittig strange situation and in a series of subsequent situations designed…

This study examined the differential effects of sex of parent, sex of child, and sex of stranger on infant behavior in a stranger-separation situation. Year-old infants (16 males and 19 females) from middle-class families were observed and videotaped twice, at one-week intervals, in a modification of Ainsworth's laboratory stranger and separation…

Disputes claims concerning the association between strange-situation behavior around 12-20 months of age and subsequent child performance. Maintains studies have precluded causal inferences about the direction and nature of effects, finding associations only when the quality of care received was stable, thus, precluding inferences about the…

Children classified as securely attached at 12 months interacted faster and more smoothly with the stranger than did avoidantly-attached peers. Microanalyses revealed different styles of interaction. Failure feedback increased efforts of securely-attached and decreased efforts of insecurely-attached children. After failure, securely-attached…
