Análisis de los procesos de interacción en díadas Madre-Hijo/a con VIH e historia de maltrato infantil: Una aplicación de la ley de igualación

The objective is to analyze the mother-child dyadic interaction processes under the formulations of the matching law and to determine if these functions are sensitive to conditions of abuse and history of maternal HIV, in a sample of 22 dyads: five with maternal HIV, 10 with behavior problems and history of child abuse and seven control dyads. The dyads were recorded during mother-child interaction sessions under two conditions: ludic and academic activity. The adjustments of the interactions were evaluated according to the equation of strict matching, generalized matching and the hyperbolic function. Abusive dyads and maternal HIV showed a tendency to undermatch, a greater tendency to bias towards prosocial behavior and dyadic interactions characterized by developing in poor environments of extraneous reinforcement with less effectiveness of social reinforcement compared to control dyads. These results indicate that vulnerability conditions are moderators of mother-child interactive processes.
