A reader pointed out to me that Schultze’s 1978 study did not find a bias to hear a fast tempo as speeding up and slow tempo as slowing down. In fact, Schultze found that we were remarkably accurate at detecting tempo changes. So we do replicate Schultze! A misreading on my part of Quinn and Watt led to the confusion.
I haven’t been able to get my hands on the article, but here’s the reference:
