Mental process and mental experience are not the same thing. The former is the operation of the mind; the latter is the subjective life that emerges from that operation. In social evaluation, implicit and explicit attitudes express this distinction. Although it is clear that they are not the same, how they differ is not. Across content domains, implicit and explicit attitude measures show substantial variability in the strength of correspondence, ranging from near zero to strongly positive. Variation in controllabiity, intentionality, awareness, or efficiency is thought to differentiate implicit and explicit attitudes. Dual-process theories and empirical evidence for moderating influences of implicit-explicit attitude relations provide a framework for comprehending relations between the operation and the experience of the mind.
