Stalling in a turn is no different than stalling with the wings level; recover the same, fly the same; it's the same airplane. It hasn't become a different airplane.
You shouldn't need stick into the turn our agaist the turn. In fact, in most light general aviation airplanes, a standard demonstration to the student should be a hands-off steep turn in which the instructor puts the airplane in a 45 degree bank, trims it for pitch, then lets the airplane fly around the turn hands-off.
That said, the aircraft, loading, degree of bank, and center of gravity do play a roll, and not all aircraft respond the same, or are flown quite the same.
For most light production airplanes, a stall in a turn is a non-event, every bit as much as it is straight and level.
Keep the inclinometer ball in the center with your feet, and fly the airplane, Whether it spins or not is entirely up to you. So far as the 150 and 172 previously mentioned...one has to work to make them spin. They don't bit agressively out of a simple turn unless the pilot isn't coming close to doing his job.
