Kibbe & Haladjian (2010). Visual attention and the tenuous binding of “what” and “where”: Evidence from infants and adults. Poster presented at the 18th Annual Object Perception, Attention, and Memory (OPAM) Meeting of the Psychonomic Society, St. Louis, MO (11/10).
The current research explores how attention is deployed to maintain bindings of object features to locations over time. Both infants and adults were studied to obtain converging evidence that cohesive object representations require sustained, focused, object-based attention to be maintained. In a multiple object tracking task with adults, only explicit tracking, not implicit tracking or spread attention, maintained bindings. In a violation-of-expectation task with infants, increasing the number of attended locations decreased infants’ ability to bind features to locations, but performance improved with development. These results suggest that feature bindings are tenuous and require sustained, focused attention to be maintained.
