Part representation is not only critical to object perception but also plays a key role in a number of basic visual cognition functions, such as figure-ground segregation, allocation of attention, and memory for shapes. Yet, virtually nothing is known about the development of part representation. If parts are fundamental components of object shape…

We examined whether infants organize information according to the newly proposed principle of common region, which states that elements within a region are grouped together and separated from those of other regions. In Experiment 1, 6- to 7-month-olds exhibited sensitivity to regions by discriminating between the displacement of an element within…

Two experiments examined whether infants are sensitive to holistic combinations of line junctions in 2-D images that adults use to derive overall 3-D structure. Results suggested that 3-month-olds are sensitive to holistic combinations of line junctions that adults use to derive 3-D information but also selectively attend to these 3-D cues in…
