86 4 Brief Survey of Cognitive Architectures
The LIDA cognitive cycle itself is a theoretical construct that can be implemented in many ways, and indeed other BICAs like CogPrime and Psi also manifest the LIDA cognitive cycle in their dynamics, though utilizing different particular structures to do so.
Figure 4.13 shows the cycle pictorially, starting in the upper left corner and proceeding clockwise. At the start of a cycle, the LIDA agent perceives its current situation and allocates attention differentially to various parts of it. It then broadcasts information about the most important parts (which constitute the agent’s consciousness), and this information gets features extracted from it, when then get passed along to episodic and semantic memory, that interact in the “global workspace” to create a model for the agent’s current situation. This model then, in interaction with procedural memory, enables the agent to choose an appropriate action and execute it - the critical “action-selection” phase!

We now run through the cognitive cycle in more detail. It begins with sensory stimuli from the agent’s external internal environment. Low-level feature detectors in sensory memory begin the process of making sense of the incoming stimuli. These low-level features are passed to perceptual memory where higher-level features, objects, categories, relations, actions, situations,
