You wouldn't happen to know what Homo sapiens sapiens, in an attempt to relinquish a little brain power and substitute it with a good dose of heart power, would be called could he become "Homo sapiens 'feeling,'" would you? 
Though affectus actually translates better, I think sentiens has more of the right connotations and connections with other fields.  For example, there is a perennial disagreement in science fiction as to whether we are looking for other sentient life forms or sapient life forms, if we're looking for those that are human-like.  
Sentire means 'to feel', but by extension also 'to be self-aware'.  I've often wondered how sapiens 'tasting' came to mean 'wise' -- I can only think it's because the wise were those who had 'good taste.'  Maybe the distinction is just that the homines sapientes cooked their food?  Grits for the mill, anyway.
