Drew, Trafton; Horowitz, Todd S.; Vogel, Edward K. – Cognition, 2013
In the multiple object tracking task, participants are asked to keep targets separate from identical distractors as all items move randomly. It is well known that simple manipulations such as object speed and number of distractors dramatically alter the number of targets that are successfully tracked, but very little is known about what "causes"…

Zhang, Hui; Mou, Weimin; McNamara, Timothy P. – Cognition, 2011
Three experiments examined the role of reference directions in spatial updating. Participants briefly viewed an array of five objects. A non-egocentric reference direction was primed by placing a stick under two objects in the array at the time of learning. After a short interval, participants detected which object had been moved at a novel view…

Mendes, Natacha; Rakoczy, Hannes; Call, Josep – Cognition, 2008
Developmental research suggests that whereas very young infants individuate objects purely on spatiotemporal grounds, from (at latest) around 1 year of age children are capable of individuating objects according to the kind they belong to and the properties they instantiate. As the latter ability has been found to correlate with language, some…

Feldman, Jacob; Tremoulet, Patrice D. – Cognition, 2006
How does an observer decide that a particular object viewed at one time is actually the "same" object as one viewed at a different time? We explored this question using an experimental task in which an observer views two objects as they simultaneously approach an occluder, disappear behind the occluder, and re-emerge from behind the occluder,…
