Building object knowledge from perceptual input

The authors in this chapter argue that a variety of mechanisms come together to support short-term learning about objects and their properties. They focus on the changes intrinsic to infants, including the development of neural circuits that afford effective active exploration of visual scenes. The authors consider external conditions that optimize acquisition of the relevant information in otherwise complex environments. The optimal object perception involves the interplay between maturation, emergent skills, experience, and available information. The authors provide empirical evidence for online learning about objects and their properties, and suggest that these repeated experiences, when maintained by the system, merge into robust and enduring object representations. This approach implicates both visual attention and simple learning mechanisms in the development of object perception, and provides a window into how the development of basic skills opens up avenues for building complex percepts.
