About six years ago I was eating lunch in a restaurant in New York City when a woman and a young boy
sat down at the next table. I couldn't help overhearing parts of their conversation. At one point the woman
asked, " So, how have you been?" And the boy, who could not have been more than seven or eight years old,
replied, "Frankly, I've been a little depressed lately."
This incident stuck in my mind because it confirmed my growing belief that children are changing. As far
as I can remember, my friends and I didn't find out we were "depressed" until we were in high school.
The evidence of a change in children has increased steadily in recent years. Children don't seem childlike
anymore. Children speak more like adults, dress more like adults and behave more like adults than they used
to.
Whether this is good or bad is difficult to say, but it certainly is different. Childhood as it once was no
longer exists, why?
Human development is based not only on innate (天生的) biological states, but also on patterns of access
to social knowledge. Movement from one social role (作用) to another usually involves learning the secrets of
the new status. Children have always been taught adult secrets, but slowly and in stages: we tell sixth graders
things we keep hidden from fifth graders.
In the last 30 years, however, a secret-revelation (揭示) machine has been brought in 98 percent of
American homes. It is called television. Television passes information to all viewers alike, indiscriminately (不
加区分地). Unable to resist the temptation, many children turn their attention from printed texts to the less
challenging, more vivid moving pictures.
Communication through print, as a matter of fact, allows for a great deal of control over the social
information to which children have access. Reading and writing involve a complex code of symbol that must
be memorized and practiced. Children must read simple books before they can read complex materials.
