Maternal sensitivity in interactions with their 2-month-old infants in Rio de Janeiro - Brazil.

This paper reports on a study of maternal sensitivity in 22 primiparous women and their infants from Rio de Janeiro, Brazil. Sociodemographic risk was assessed through an interview, and videotaped naturalistic home observations were used to assess maternal sensitivity, and its relation with warmth, verbal and physical engagement, and camera awareness. A K-means cluster analysis was performed to examine patterns of risk in relation to maternal sensitivity.

Maternal sensitivity in mother-infant interactions in Rio de Janeiro - Brazil.

This article reports on a study of maternal sensitivity in 22 primiparous women and their infants from Rio de Janeiro, Brazil. Two semi-structured interviews were conducted, as well as videotaped naturalistic home observations of the dyads. A K-means cluster analysis was performed to examine patterns of risk in relation to maternal sensitivity.

Different kinds of infants' smiles in the first six months and contingency to maternal affective behavior.

Infants' smiling is considered an expression of affection, and an index of cognitive and socio-emotional development. Despite research advances in this area, there is much to explore on the ontogeny of smiling, its meaning and the context in which it is manifested early in life. This study aimed at: (a) investigating smiling patterns in these different developmental moments in early infancy, (b) analyzing patterns of association between babies' smiles and their mothers' affective behaviors, and (c) verifying whether babies can answer contingently, with smiles, to mothers' affective behaviors.

Self-recognition and self-regulation: the relationship with socialization trajectories and children's sex.

The initial process of self development involves interaction with others and the establishment of relationships taking different paths depending on the socio-cultural context. Self-recognition and self-regulation are considered manifestations of this development between 18 and 24 months of age. This study aimed at analyzing the relationship between these two aspects, maternal beliefs about autonomy and relatedness, as well as identifying differences between boys and girls in this developmental stage.

The ontogenesis of smiling and its association with mothers' affective behaviors: A longitudinal study.

Two babies were observed from their third week to their sixth month of life. Our goals in the study were: to investigate developmental changes in smiling patterns; to analyze the smiling patterns observed in the presence of mother's affective behaviors, and to verify whether the babies can answer contingently, with smiles, to mothers' affective behaviors. The babies and their mothers were videotaped at home.
