Most of the current theoretical research on adolescence is based on past studies in which risks and opportunities are different from those faced by teenagers nowadays. After a brief description of the main characteristics of the present times, the author offers an hypothesis on the impact of postmodern "scenarios" on identity development in adolescence. She underlines new risks and new opportunities analysing two specific areas: Web 2.0: virtual and real identity; migration and multiculturism: cultural identity. The author presents the results of her research in these two specific areas to underscore the main challenges teenagers and adults have to deal with today.
