In sum, psychologists have moved away from linear models of cogni- tion toward models involving multiple pathways, multiple levels of activation and types of activation, involving complex combinations of suppression and enhancement. Departure from linear models has forced psychologists to drop, as well, neat dividing lines between con- scious and unconscious, supraliminal and subliminal, controlled and involuntary processes. These shifts have brought in their train a sweep- ing reconceptualization of the nature of emotion – a “revolution in the study of emotions,” as Fischer and Tangney have noted (1995:3).
