1 - Introduction
See firstly the supporting commentary for this material.
Morton's (1981) 21-Box Model: Here is Morton's (1981) expansion of the earlier processing models. It is a distillation of models going back to the early 1960s, including those by Morton himself (1964 - click here, 1979 - click here), Marshall and Newcombe (1966, 1973 - click here), and Morton and Patterson (1980). It was deliberately left uncaptioned in the original because it was intended to convey a general layout and level of complexity rather than to make specific points. Nevertheless, a central cluster of processes (feint grey), parallel input and output pathways, and several bypass and feedback routes can all clearly be seen, all of which are met again in later supermodels, such as those by Ellis and Young (1988) and Kay, Lesser, and Coltheart (1992).
