This document discusses and analyzes the theoretical implications as of developmental psychology, relating to variables that are essential for the study of socialization, such as parental ethno-theories and the context of the mother-child interaction, from the specificity of a cultural context. A relevant subject for psychology is approached, focusing on subjects of cultural, trans-cultural, and developmental psychology. Parental beliefs, conflict resolution strategies, and cultural orientation were assessed in two Costa Rican samples, a rural (n=14) and an urban (n=14). 28 mothers and their pre-school children were assessed in three interaction episodes (free play and two scenario conflict situations). Collectivis Scale (Yamaguchi, 1984), Family Allocentrism Scale (Lay & others, 1998) and Socialization Goals Inventory (Harwood, 1992) plus a semi-structured interview were applied. Interdependent cultural orientation among Costa Rican mothers and differences among zone were tested. Despite an interdependent cultural orientation, urban and rural samples showed certain variability concerning interactive compenents, parental beliefs and cultural values related to conflict resolution and conflict resolution styles. Results allow to detail certain cultural specific values concernin parenting, interaction patterns, parental beliefs and social values related to conflict resolution.
