A new study suggests that girls perform better on tests of reading and writing while boys perform better on tests of science and mathematics.

The report, by Larry Hedges and Amy Nowell of the University of Chicago, analyzed six large national surveys of performance by American male and female teen-agers on tests of mental ability conducted over the last 30 years.
