Preattentive Object Files: Shapeless Bundles of Basic Features

@article{citeulike:324130, abstract = {A considerable body of recent evidence shows that preattentive processes can carve visual input into candidate objects. Borrowing and modifying terminology from Kahneman and Treisman (1984), this paper investigates the properties of these preattentive object files.

Appreciation of the overall shape of an object appears to require the binding together of local form features--a process that requires attention.
