None of the “cognitive milestones” websites that come up on a quick google search address this.
I’m wondering what is known (or even what is wondered about) concerning the development of logical understanding in young children. I should clarify that I don’t necessarily mean the ability to solve logic puzzles. Rather, I have in mind understanding what makes for a complete argument, what constitutes a completed attempt at linguistic persuasion, what sorts of sequences of assertions ought to be felt as plausibly persuasive or motivational, and so on. So you might call what I have in mind the development of “rhetorical skills” instead. Sort of logico-rhetorico-communicative skillsets. Something like that.
I ask because damned if my kid isn’t already trying to run logical and rhetorical circles around me. I want to know if he’s supposed to be doing this yet.
