THE WEEK, Page 23HEALTH & SCIENCEEt Cetera
DIMINISHED CAPACITY
Many researchers think the hallucinations and delusions of
schizophrenia reflect a physical deterioration of the victim's
brain. Now comes a new study from Harvard that strengthens that
theory. Magnetic-resonance imaging of 15 schizophrenic and 15
normal men shows that the former have less gray matter in the
left temporal lobe, a region believed to be important to
language processing. The degree of shrinkage matched the
severity of thought disorder -- implying that while a cure for
the disease is nowhere close, scientists may at least be zeroing
in on the cause.
WHAT'S WRONG WITH THIS PICTURE?
Many parents think their babies are geniuses. Now a report in
Nature argues -- not altogether convincingly -- that tots can
actually add and subtract at five months. After showing objects
to infants, a psychologist hid the objects with a screen; she
then reached behind the screen to add or remove one. But she
added or subtracted objects surreptitiously as well. When the
screen was lifted, the infants stared longer at a wrong number
of objects than they did when the result was correct.
Conclusion: they were doing a double take. Ah, science!
