It is generally assumed that storing predictive relations between two events in memory as bi-directional associations does not require conscious awareness of this relation, whereas the formation of unidirectional associations that capture the direction of the relation does. This study reports a set of experiments demonstrating that unidirectional associations can be formed even when awareness of the relation is actively prevented, if attention is “tuned” to process predictive relations. When participants engaged in predicting targets based on cues in an unrelated (...) task before the actual acquisition phase, unidirectional associations were formed during this acquisition phase even though E1 was presented subliminally. This suggests that although processing the relation between events may often be accompanied by awareness of this relation, awareness is not a prerequisite for the formation of unidirectional associations.

This article argues that conscious attention exists not so much for selecting an immediate action as for using the current task to focus specialized learning for the action-selection mechanism and predictive models on tasks and environmental contingencies likely to affect the conscious agent. It is perfectly possible to build this sort of a system into machine intelligence, but it would not be strictly necessary unless the intelligence needs to learn and is resource-bounded with respect to the rate of learning versus (...) the rate of relevant environmental change. Support for this theory is drawn from scientific research and AI simulations. Consequences are discussed with respect to self-consciousness and ethical obligations to and for AI. (shrink)
