the evolution of the meta-management layer made possible the evolution
of additional layers in perceptual and action systems related to the needs and
capabilities of the metamanagement layer (e.g., using the same ontology for
labeling internal states and perceived states of others; see Chapter 9 of
Sloman, 1978; Sloman, 1989, 2001b; Sloman & Chrisley, 2003).

Figure 8.3. The H-CogAff architecture is a version of the CogAff architecture of
Figure 8.2, which has many of the features posited for the cognitive architecture
of adult humans. Note particularly the representation of personae, the activation
of motives, the long-term associative memory, and the attentional filters
that modify not only the treatment of sensory data but also the interactions
between different levels of sensory processing. Meta-management may be able
to inspect intermediate states in perceptual layers, e.g., sensory quality. Indeed,
the architecture of H-CogAff assumes that the evolution of the meta-management
layer made possible the evolution of additional layers in perceptual and
action systems related to the needs and capabilities of the meta-management
layer. Not all possible links between boxes are shown.
Our above conjectures imply that our folk-psychological concepts and theories
all have architectural presuppositions. However, since those presuppositions
