I wonder if I’m imagining my reactions,
or exaggerating them, but
Schwartz tells me that he’s gotten back
the first set of data on a group of highreactive
children Kagan studied from
four months of age—and sure enough,
the amygdalae of those children, now
grown up, had turned out to be more
sensitive to the pictures of unfamiliar
faces than did the amygdalae of those
who’d been bold toddlers. Both groups
reacted to the pictures, but the formerly
shy kids reacted more. In other words,
the footprint of a high- or low-reactive
temperament never disappeared in adulthood.
Some high-reactives grew into socially
fluid teenagers who were not outwardly
rattled by novelty, but they never
shed their genetic inheritance.
