The parallel processing model

According to the parallel processing model, analysis of different stimulus attributes, such as identity and location, proceeds simultaneously along different pathways, even from the earliest stages. For example, the fact that there are cones (of three types, maximally sensitive to different wavelengths of light) and rods in the retina is evidence for multiple mechanisms that extract information in parallel from the retinal image.
