What i heard is that it is designed to imitate the stick sensation smaller airplanes have as the wind buffets the controll surfaces when a stall develops.

And pilots from an early stage in their flying training conditioned to push the stick forward when that happens.

Not in this case, because the 'stick shaker' activates when the aircraft is stalling or close to stalling. The only sensible option in this scenario is to lower the angle of attack, that is, pitch forward. If you have both the GPWS 'terrain, pull up' warning and the stick shaker warning simultaneously then you are in a sticky situation indeed.
