The study examines the phenomenon of adolescents' idolization of pop singers. Male and female adolescents from three age groups (ages 10-11, 13-14, and 16-17) were compared with regard to the intensity of idolization, its behavioral manifestations, causes for selecting the idol, and reliance for knowledge on the idol. The results of self-reports indicated that the phenomenon of idolization, expressed especially in worshipping and modeling, is strongest in the youngest age group and decreases in intensity with age. Also, it was found that girls idolize singers more than boys. The youngest age group, especially girls, rely on singers with regard to knowledge concerning personal matters. These findings were explained within the frameworks of gender differences, adolescence characteristics, and youth culture development.
