I look at it from the perspective of evolution of minds. There is a simple reinforcement learning mechanism in brains, as described in: HOW THE BASAL GANGLIA USE PARALLEL EXCITATORY AND INHIBITORY LEARNING PATHWAYS TO SELECTIVELY RESPOND TO UNEXPECTED REWARDING CUES. Brown, J., Bullock, D., and Grossberg, S. (1999). Journal of Neuroscience. on-line at http://cns-web.bu.edu/pub/diana/BroBulGro99.pdf But this solves the credit assignment problem in only very limited cases. I think that consciousness (and other things) evolved in order to do reinforcement learning in more general situations. That is, the need for robust reinforcement learning provided the selection pressure for consciousness.
