Acesso em: .https://repositorio.ufpa.br/handle/2011/18651This study was based on Heidi Keller’s theoretical framework of Parental Investment Model, which indicates six parental systems – primary care, body contact, body stimulation, face-to-face exchange and narrative envelope – and three interaction mechanisms – attention, contingency and warmth and which are independent of each other and the predominance of one or the other depends on the culture and socioeconomic characteristics. The goals of this work was to characterize the parental investment of dyads mother-baby of lower socioeconomic class (CEB) and middle-class (CEM) of the city of Belém and the conversational style used in verbal emissions by the mothers during verbal interaction with your babies. The participants in the study were 20 mothers (nine of CEB and 11 of CEM). The mean age of mothers of CEB was 24,5, most had the elementary school (77,8%) and secondary (22,2%), complete or not, have monthly income less than mothers of another group and living in outlying areas. The mean age of mothers of CEM was 30,7, most had the undergraduated school (63,3%) and living in central areas. Have been observed and recorded mother-baby interactions in bathing and exchange sessions, at the home of the dyad, for later analysis and transcription of verbal behavior with the Transana 2.41. The results indicated that mothers of CEB gave more emphasis to proximal parental practices during their interactions, but also have submitted distal practices but less frequently. Mothers of CEM gave emphasis to practices echance independence and interdependence. As interaction mechanisms, it was noted that the mothers of both groups were more contingents for positive signals of baby than negatives, characteristic of societies that prioritize the independence and autonomy of the subject; however, showed more warmth to respond to positive signals compared to the tives. In relation to the conversational style, mothers of CEB have used more frequently directive style, and mothers of CEM, used both styles with nearby frequencies These findings indicate a pattern interdependent for CEB and a pattern autonomous-relationade for CEM.that both groups showed parental practices that enhance independence and interdependence presenting a pattern that fosters the development of children’s autonomous–relational selvesAcesso AbertoAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Investimento parentalParantal investimentInteração mãe-bebêCaracterísticas sociodemográficasMother-baby interactionSociodemographic characteristicsDissertaçãoCNPQ::CIENCIAS HUMANAS::PSICOLOGIAProcessos Comportamentais ComplexosECOETOLOGIAPSICOLOGIA EXPERIMENTAL
