We posit a model of emotion and nonverbal behavior (NVB) that incorporates a perspective of consciousness. We leverage an understanding of the neural pathways innervating NVB to describe the complexity of its neural architecture and the links between those pathways and mental states. We suggest that all NVB are activated by both cortical and subcortical structures, allowing for unconscious, coordinated movements across multiple channels as well as conscious, less coordinated movements; that mental states are associated with both cortical and subcortical (...) structures; and thus that NVB will occur in multiple channels, both unconsciously and consciously, and differ across time. We discuss the implications of this model for future theory and research. (shrink)
