Mothers read stories to their children (N = 41) aged between 3.3 years and 5.11 years old, and children then completed two false-belief tasks. One year later, mothers read a story to 37 of those children who were also given four tasks to assess their advanced understanding of mental states. Mothers' early use of cognitive verbs in picture-book…

Reviews Bell and Ainsworth's 1972 study and suggests that their main conclusion, that maternal responding implied a reduction in infant crying, was not supported by their data. (JMB)

Cites evidence from the Bell-Ainsworth paper and from other studies which supports the interpretation that Gewirtz and Boyd claims was unjustified. (JMB)

This report describes a method for objectively assessing the style of mother-infant interaction without regard to the specific content of the interaction. Application of this method to systematic observations made of 45 mother-infant dyads revealed sex and parity effects. (Author/JMB)

Examined associations between mothers' and trained observers' Attachment Q-Set (AQS) sorts for preschoolers and assessed mother-observer concordance in relation to observers' confidence about how representative the behavior they witnessed was of the domain of AQS items. Found that mothers' and observers' sorts were significantly intercorrelated;…

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)

Demonstrated that time sampling is inaccurate for estimating durations or frequencies of behaviors. Also concluded that (1) individual or group differences can change depending on whether time sampling or continuous sampling is used; and (2) error rates are high when bout lengths of behaviors are short or when interval length is long.

An analysis using data drawn from Nancy Bayley's Berkeley Growth Study is performed for didactic purposes to illustrate the use of structural equation modeling on a child development data set. Alternatives to standard latent factor approaches are demonstrated for use in research situations in which the subject-to-variable ratio is less than…

Aimed (1) to determine whether a time sampling, frequency-count procedure for assessing mother-infant interaction could capture a set of theoretically important dimensions, and (2) to chronicle both ability and change within the mother-infant relationship. A total of 74 dyads were observed when infants were 1, 3, and 9 months of age. (Author/RH)

Develops a methodology for studying emotion socialization and examines the synchrony of mother and infant expressions to determine whether "instruction" in display rules is underway in early infancy and what the short-term effects of such instruction on infant expression might be. Sixty dyads were videotaped during play and reunion after brief…

The relation between maternal presence and infant's vocalization depended upon the infant's state: when the infant was in the active awake state, he vocalized less in the presence of the mother than when alone, thus indicating that the majority of early vocalizations are associated with a non-social situation.

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)

Uses structural equation modeling to combine traditional ideas from repeated-measures ANOVA with some traditional ideas from longitudinal factor analysis. The model describes a latent growth curve model that permits the estimation of parameters representing individual and group dynamics. (Author/RH)
