This study evaluates the effect that two experiences of political socialization had on different psychosocial and psychopolitical variables (social dominance orientation, right-wing authoritarianism, attitudes towards equality, socially conscious behaviour, empathy, attitude towards unfair behaviour by authorities, sociopolitical participation) in children in the city of Córdoba (Argentina). Specifically, it analyses the effect of participation in a social organization that promotes citizen education (Study 1), and participation in the Alternative Political Socialization Programme (APSP) (Study 2) created for this research. Likewise, a comparative analysis of both experiences was performed (Study 3). Children aged 10 and 11 participated in the experiences. A quasi-experimental design was used with a pre-and post-test, along with a quasi-control group. The results suggest a significant effect in the variables studied based on participation in these experiences, with differences according to the kind of programme. The study underscores the importance of designing alternative political socialization mechanisms geared at citizen training in childhood.
