Coding Systems in Perception and Cognition

Abstract

The variety of experiments completed under the contract successfully isolated ways that humans encode and employ information to meet task demands. The results indicate that, when a stimulus is presented, two or more separate coding processes proceed in parallel. One process may build up an iconic representation of the stimulus object; another process is the retrieval of one or more name codes for the stimulus pattern. For some tasks the response depends completely on the iconic code; for others it depends on the name code. Not only do humans typically convert iconic codes into name codes (abstraction), but, when the occasion is appropriate, they can reverse the process and generate iconic representations from name codes. The build up or construction of the iconic representations appears to take place in a three-dimensional analog medium.
