Are teens and young adults more narcissistic (自恋的) today than in the past That’s the view of a California researcher who studies (1) people.

In her new book, The Narcissism (2) : Living in the Age of Entitlement, psychologist Jean Twenge of San Diego State University and (3) W. Keith Campbell of the University of Georgia say research shows (4) young people today have "narcissistic traits" than in (5) generations. Such traits, Twenge says, include a very.

"We’ve been on this self-admiration cultural (8) for a long time," Twenge says. (9) Twenge’s take on today’s young people isn’t universal. Studies by other researchers, including Canadian (10) Dr. Kali of the University of Western Ontario, have used the same data but found (11) results. "They put a different (12) on it," Kali says.

Twenge’s studies have found more narcissistic traits and a (13) rate of increase among college students today, but Kali found that students’ narcissism was (14) greater in 2006 than in 1976. Twenge’s most recent paper studied the same data as Kali--more than 20 000 college students from 2002 to 2007.

Twenge’s book (18) just a month after The Mirror Effect : How Celebrity Narcissism Is Seducing America, a book co-written by behavioral (19) Drew Pinsky, (20) suggested that a celebrity-obsessed culture is causing more narcissism.
