PSYB55H3 Chapter Notes - Chapter 6.10: Face Perception, Outline Of Object Recognition, Retina
Document Summary
Object recognition can be achieved in a multiplicity of ways and involves many levels of representation. It begins with the two-dimensional information that the retina provides. Our visual system must overcome the variability inherent in the sensory input by extracting the critical information that distinguishes one shape from another. Only part of the recognition problem is solved by this perceptual categorization. For this information to be useful, the contents of current processing must be connected to our stored knowledge about visual objects. We do not see a meaningless array of shapes and forms. Rather, visual perception is an efficient avenue for recognizing and interacting with the world (e. g. , determining what path to take across a cluttered room or which tools make our actions more efficient). Moreover, vision provides a salient means for one of the most essential goals of perception: recognizing members of our own species.
