Such awareness is required for the simplest and most common type of composite acts: sequences. To perform a sequence of acts, a cognitive agent should start performing one step when, and only when, it comes to believe that the previous one has been completed. We present a model for interleaving action, reasoning, and perception in order to allow for the conscious performance of sequences of acts. To define such a model, the notion of act completion needs to be characterized. This is achieved by developing a formal system in which acts are classified along the dimensions of telicity and primitiveness. The proposed system includes and go beyond the traditional binary telic/atelic distinction.
