Reunion Patterns in the Still‐Face Paradigm as Predicted by Maternal Sensitivity and Dyadic Coordination

Previous studies have suggested that the reunion episode of the still‐face procedure has the potential to reveal the regulatory resources of the mother–infant dyad that appear to be predictive of future adaptation. Nevertheless, differences across dyads with respect to these resources have received little attention, as also have the factors that are responsible for such differences. This study addresses this gap in the literature by testing whether the dyad reunion patterns can be predicted by the mothers' sensitivity assessed 3 months earlier, and by the contingent degree of the matched states in the play episode. Three dyadic patterns were identified through cluster analysis, which were characterized by playful, neutrally matched, and disrupted interactions. Multinomial logistic regression shows that the mothers' sensitivity predicts membership to the playful group, and the matched states in the play episode predict membership to the neutrally matched and disrupted groups. These findings show that the vulnerability to disrupt an ongoing interaction after a temporary perturbation is seen for only some dyads; moreover, they support the view of early regulatory development as a multidetermined achievement. Overall, these findings have important theoretical implications related to the identification of early regulatory difficulties as precursors of later developmental outcomes.     

The Pointing–Vocal Coupling Progression in the First Half of the Second Year of Life

This study investigated the development of the pointing–vocal coupling system. We were interested in the infants’ behavior to attune prosody with pointing intentions. Twenty‐five children were involved at 12, 15, and 18 months of age in an experimental procedure devised to elicit imperative and declarative pointing. Pointing, vocality associated with pointing, and the prosody of that vocality were analyzed. A significant increase in the coupling of pointing and vocality was observed from 12 to 15 months, and in the ability to differentiate prosody with respect to the intention of the gesture from 15 to 18 months. Also, the infants who pointed declaratively at 12 months were likely to couple declarative pointing with vocality at 15 months, and the infants who coupled at 15 months were likely to differentiate prosody by the pointing intention at 18 months. Results suggest that the match between prosody and pointing intentions emerges gradually during the first half of the second year of life. They also show a relationship between earlier and later pointing–vocal coupling, and a role for declarative communication in promoting that progression. Overall, our study supports the view of intentional communication as a time‐based and context‐based developmental process.     

Households and Territory. The Location of the Population of Rome in Relation to Housing Supply Characteristics

This study forms part of a general programme of research aimed at evaluating the quality of life in Rome. In particular, we have wished to analyse the way in which housing quality, measured with indicators of housing structure and utilization, intersects with the quality of urban livability, measured here only with indicators of social background, homogeneity and hardship referring to subjects living in the individual segments of the city. Groups of territorial areas, homogeneous by housing typology, were identified using multivariate data analysis and it was thus shown how particular typologies of household respond to this supply. From this emerged a particular model of development of the city in concentric bands, within which the originally differentiated households have tended over time to assume homogeneous characteristics.     

Developmental Trajectories for Mother–Infant Coregulation in the Second Year of Life

Ten dyads were observed biweekly from 10 to 24 months of infant age while playing together at home with a set of toys. The aim was to examine whether mother–infant coregulation changes over the second year of the infant’s life and whether there are individual differences in that process. Normative trends as well as variability between and within dyads were tested using a multilevel modeling technique. We found that unilateral coregulation, in which only the mother was actively involved in play, largely prevailed at the beginning of the year and then decreased linearly, while symmetrical patterns, implying that the infant was also involved, were for the most part absent at the beginning but then increased rapidly, overtaking unilateral from the middle of the year on and becoming predominant by the end. In particular, symmetrical episodes of shared affect and shared action increased first and then decreased, being replaced by shared language. Variability in data was significant between the dyads, with some dyads advancing toward symmetrical coregulation at an earlier age and more rapidly than the others. It was also significant within the dyads, as the increase in symmetrical coregulation unfolded in a quite irregular manner across the sessions, unlike the decrease in unilateral. Results are discussed with reference to a view of joint attention development as a gradual and complex process.
