Hi Angela, A great talk and discussion! I was interested in your point on tasting water being required for it to be a goal during development. Would you mind letting me know some literature on this topic?

Hi Nao - glad you enjoyed it! Some papers below point to appetitive behaviors being learned (vs consummatory behaviors):

This one is very old, but contains the idea that appetite must first exist: https://www.journals.uchicago.edu/doi/pdfplus/10.2307/1536346

I am by no means an expert on this literature (was pointed to it by collaborators) but I find it very interesting and relevant for what we consider to be a reward...
