摘要: Human activity is rife with momentary control problems: hesitations, dysfluencies, false starts, memory lapses, and errors. This seems rather strange, because normal human action also tends to be effective, complex, adaptive, fast. Clearly our system the product of many millions years evolution: Why then it so prone problems? a paradox that emerges most clearly in case inadvertent slips, which may defined as actions reveal mismatch between reportable intention overt performance (Baars, 1988; MacKay, 1987; Norman, 1981; Reason, 1979).
