NEW YORK — Reports of sudden acceleration in Toyota Prius models have spiked across the country. But that doesn't mean there's an epidemic of bad gas pedals in the popular hybrid.

Experts on consumer psychology say the relentless negative media attention Toyota has received since the fall makes it much more likely that drivers will mistake anything unexpected — or even a misplaced foot — for actual danger.

"When people expect problems, they're more likely to find them," said Lars Perner, a professor of clinical marketing at Marshall School of Business at University of Southern California.
