Usability News - 5.2 2003 -- Breadcrumb Navigation: Further Investigation of Usage: "Of the participants that were exposed to a site with a breadcrumb trail (n=30), 40% used the breadcrumb five or more times to navigate on the site (Range = 5 - 31, n=14). However, this accounted for only 6% of the navigation overall (see Figure 6)."
They also tried to measure the strenght of the "mental model" the users have of the site structure. I didn't like their methodology there, which brings up the question: what methods have you used to measure the mental model of a site structure? (PS: The concept "mental model" in information architecture is imo misunderstood and misapplied, but I'll write more on that at some later date.)
