“…This second line of research suggests that core values and identities are acquired at an early age and remain relatively stable during the life cycle (Sapiro, 2004). A growing body of research indeed proposes that political attitudes and behaviors are shaped early in life, for example, through socialization within families, schools, peer groups, participation in community projects and youth associations (Jennings and Niemi, 1981;Flanagan and Sherrod, 1998;Hahn, 1998;Jennings and Stoker, this issue;Niemi and Junn, 1998;Oswald and Schmid, 1998;Yates and Youniss, 1999;Galston, 2001;Torney-Purta et al, 2001;. Of course, changes in attitudes do occur during adulthood as well (Sigel, 1989a), partly as a result of job experiences (Kohn and Schooler, 1982), family transitions (Lesthaeghe and Moors, 2001) or period effects, but in general these changes do not tend to interfere with the basic pattern established early in the life cycle.…”
