A. The serial processing model is now known to be inadequate, or at least incomplete
B. The serial model has been replaced, at or at least modified, firstly by the parallel processing model and then, most recently, by the recurrent processing model
C. 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
D. According to the parallel processing model, the fact that there are cones and rods in the retina is evidence for multiple mechanisms that extract information in series from the retinal image
