Ben. Along with predictive implication and attraction, sequential logical operations are important, represented by operators such as SequentialAND, SimultaneousAND and SimultaneousOR. For instance: PredictiveAttraction SeguentialAND Teacher says 'fetch' I get the ball I bring the ball to the teacher I get

t is a compound link structure that consists entirely of executable atomic predicates (e.g. pick_up, walk_to, can_do, etc.) and temporal links (e.g. SimultaneousAND, PredictiveImplication, etc.) Records of predicate execution may then be made using ExecutionLinks, e.g. ExecutionLink pick_up ( me, ball_7) is a
