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.
However, Quinn and Watt do cite a 1997 article which claims to find the bias I describe in the post from yesterday and the day before.
I haven't been able to get my hands on the article, but here's the reference:
Vos, P. G., van Assen, M., & Fraiiek, M. (1997) Perceived tempo change is dependent on base tempo and direction of change: Evidence for a generalized version of Schulze's (1978) internal beat model. Psychological Research, 59, 240-247.
I found the article via Web of Science, and Springerlink.com hosts it. The problem is probably the name of the third author, which is not Fraiiek, but FraÅek (an n with an inverse ^), and is listed as Franek. If you are unable to access the document I would be happy to send it to you.
