      In the Rolls paper he more or less distinguishes a valence (direct punishment to reward) and a value (gain vs. loss of reward) axis, and links the presence or absence of reward vs. punishment to specific emotional responses. I think I buy it. Am curious about objections though.pic.twitter.com/2QmRKufe9e

      I had been arguing w a colleague that direct punishment or threat is qualitatively different from loss of reward - not just because primary v secondary. I sketched 2 axes and realized I'd gotten the idea from somewhere, maybe Panksepp. @WilCunningham reminded me it was Rolls.

      Great. Thanks. It is very interesting to see these spaces of values and emotions. Late Panksepp differentiated emotions further (4-7 types). I am curious as to how his differentiated emotions map to these spaces.

      Another interesting question is “what is happening when preferences reverse?” Reversals occur across different emotional states. Can adding different axes explain these phenomena?

      Do you mean in reversal learning tasks? Can you explain a bit more what you mean?

      No. I mean reversal of preferences of choice options. Value or utility is 1D precisely because it can determine which choice option is chosen consistently. This is the definition of it in an economical sense. Reversal of preference means that this does not hold.

      Without learning, but under different emotional conditions, reversal of preferences can occur.

      1/ So my take on Rolls is emotional states arise from where you are in relation to gain or loss/absence (and striatally mediated approach v stopping) or gain and punishment (and Amydgal/NE/stress system mediated approach v avoidance) which can also result in preference reversal

      So rather than seeing the emotional state as causal he would see it as emergent from the same configuration of circumstances that lead to preference shift.

      I think your view is right. I think the problem is the current definition of value/utility, which is restrained (for a good reason) to be 1D (not allowing preference reversals). This is largely historical consequences of burrowing the concept of value/utility from economics.

      Agree. I think research on motivation in relation to decision making and emotion have been largely siloized to the cost of both. It's been refreshing to look back on that "older" research integrating both.
