Document Summary
What are the criteria for being a representation: intentionality criterion, information-carrying criterion. Feature: meaningful sensory aspect of a perceived stimulus. Examples of neurons that serve as feature detectors, including neurons that respond to line segments, and even to individual people (i. e. halle berry) Amodal symbols are built from abstract and arbitrary symbols i. e. abstract symbol can be used to represent a canary (i. e. Canary:can singis yellowhas featherscan flyhas wingsbreatheseatsetc. tootell, r. b. h. , et al. (1982). kosslyn, s.

Information stored in network is stored in amodal semantic network (collins and quillian) Provides neutrally inspired mechanisms for storing and using same information.
