web app - Is there any public research on effectiveness of activity indicators, progress bars, and progressive loading?



Activity indicators (spinning wheel) and progress bars are very common across many applications.


A new approach I have noticed is when an application shows the containers of the page or content while still loading the actual content. When the content is loaded it fills in the details replacing the empty area. Facebook's iOS app will load the container of a picture, with a big white rectangle, until it loads the actual picture a split second later. There is no activity indicator blocking user interaction.


Are there any articles or research papers that go into more depth on this topic? I have searched the previous posts but I cannot find anything that discusses this progressive loading approach.
