Europe retained the trophy two years ago despite being 10-6 behind ahead of the final day, and Torrance has suggested that such a disappointing result for the Americans could harm their chances at Gleneagles.
"If it was me I don't think that would spur me on," Torrance told reporters. "I would think that would put a lot of doubts in my head, the fact that you're four points clear at home and you lose.
"I don't know how that would spur you on, it's almost more [deflating]."
Torrance is serving as one of Paul McGinley's vice captains at Gleneagles.
