Basics......I agree
It goes all the way back to your first flying lesson the first clue should be the controls getting less effective, then the aircraft attitude followed by the light buffet...... Without getting too far into the theory those are the clues that should be ringing alarm bells in the mind of a low time pilot long before the stall warner sounds.
To fail to teach that, and mitigate that with a whole lot of guff derived from videos of airliner flying is to sow the seeds of an accident be it a C152 Turing final at some small airfield of an A330 over the Atlantic.
