I had not, so it was an interesting read, however I do believe that what is being observed is commonality in associated learning patterns in the cortex (recursive evaluation) rather than what I think is the universal grammar of sorts via the Hippocampus. Aggressive, sharp, shock sounds also tend to be inversely associated with clam (ability to sleep through a sound a key divisor) so become emotionally associated (trigger a chemical release), which adds to additional recursion or feedback within an evaluation. Any sound pattern that triggers adrenalin for example may well not be considered “calm” or “soft” upon evaluation, regardless if the audible pattern has any real associated meaning.
The emotional attachment to learning of concepts I do believe is fundamentally critical to the provision of an evaluation mechanism. Words would otherwise all “mean” the same and just end up a pattern that the likes of GPT-3 can throw out without any emotional coherence as to meaning in context.
