Gray Zones at the Emotion/Cognition Interface: A Commentary

Abstract
Two thing are obvious from the subjective experience of emotional states: (1) emotions have a power of their own in directing and disrupting behavioural options, thinking processes, and bodily states, all the more so if one is immature; (2) our thoughts and appraisals of events can instigate or inhibit feelings to a substantial extent, all the more so as we age and get more experienced. These common introspective observations suggest that there are reciprocal influences between emotions and cognitive processes, the strength of which change as a function of developmental stages. Alternatively, these observations, especially the latter, could suggest that emotions and cognitive processes are orthogonal reflections of the same brain systems. In the preceding article, Gray advocates the siren-song attractions of the latter view-a delusional view, at least for psychobiologists, I would argue. In this commentary (invited by the editor of this special issue of Cognition and Emotion), I will reaffirm the utility of emotiodcognition distinctions in behavioural brain research, and attempt to coax Gray back to a more traditional view from which he now seems to have departed. Although Gray covers many issues with which I agree, in typical hominid fashion I will bluntly proceed to focus more on those matters with which I disagree. I thank the editor for requesting me to share this alternative view. Literature citations are used sparingly, but much of the relevant material can be accessed from the cited reviews from our laboratory.
