ABSTRACT

For an animal, an object is a cognitive achievement, the outcome of a process that

segments sensory/perceptual input into regions as it attends to the sensory/perceptual

dimensions that have proven useful in making predictions, dimensions such as color,

texture, size, and (the multiple dimensions that make up) shape. An object can be seen in

part as the co-occurrence of a set of values on these dimensions, that is, as a feature

vector.
