Recent research on different layers in an integrated architecture, using differing forms of representation, different types of mechanisms, and different information, to provide different functional capabilities, suggests a way of thinking about classes of possible architectures (the CogAff schema), tentatively proposed as a framework for comparing and contrasting designs for complete systems. An exceptionally rich special case of the schema, H-Cogaff, incorporating diverse concurrently active components, layered not only centrally but also in its perceptual and action mechanisms, seems to accommodate many features of human mental functioning, explaining how our minds relate to many different aspects of our biological niche. This architecture allows for more varieties of learning and development than are normally considered, and also for more varieties of affective states, including different kinds of pleasures, pains, motives, evaluations, preferences, attitudes, moods, and emotions, differing according to which portions of the architecture are involved, what their effects are within that and other portions of the architecture, what sorts of information they are concerned with, and how they effect external behaviour. These ideas have implications both for applications of AI (e.g. in digital entertainments, or in the design of learning environments), and for scientific theories about human minds and brains.

Here's a sketch of H-Cogaff
