The normal course of events is for a sentence to enter this supertask. control knows that all sentences first need to be translated into a conceptual form; to accomplish this, the sentence is passed to sentence processing. control receives a concept from the sentence processing supertask, along with the set of suggestions, expectations, anticipations, and requests which may have been generated. In Squire, the first sentence (consisting of those five clauses) is given to the control supertask which passes it to sentence processing for translation. A trap concept is given back to the control task; this concept includes the information concerning the location of the Enterprise. In addition, the anticipation that the trapper will be revealed is passed to control.
After this initial translation, control requests that reasoning attempt to understand the new concept. In this case, the reasoning supertask reinforces the need to discover who is trapping the Enterprise. Also, since the Enterprise is a known concept, prior scenarios which involve the ship being trapped are retrieved from memory (only the most active ones are retrieved). This will enable the reasoner to start to comprehend the story by predicting the future events.
After reasoning occurs, story structure comprehension and scenario comprehension are both given the concept to work on. The setting can be filled in through the location information which is revealed in this initial concept. Other story structure elements can not be explicitly determined from this first sentence, although an unknown character is assumed to exist. scenario comprehension uses the information contained in this first sentence to begin to build a representation of the events of the story; in this case, the reader knows a trapping action has occurred. This can trigger a number of higher-level concepts, such as a hostage situation, a military coup, or a Klingon attack on the Federation's flagship.
When the processing of the current sentence is completed, the control supertask takes the next one from the story and begins the next stage. If there are pending requests from earlier comprehension, then these will be addressed as the next sentence is being read.
