At normal flying speed, ailerons produce mostly roll, and some adverse yaw (secondary effect). The rudder produces yaw, and eventually roll (secondary effect). I'm sure you know that.
Near the stall, (i.e. at high angles of attack) the ailerons will produce a far more pronounced yaw, and reduced roll response. The rudder will produce less yaw, and a more pronounced rolling tendency. In some types you will find that at some speed near the stall, the secondary effect becomes the dominant. Not to mention the already made point that in many types, aileron use at the stall will create a wing drop in precisely the opposite direction to the roll 'commanded' by the ailerons. That may have nothing to do with stall entries, but it has everything to do with your assertion that:
Which types? please specify.
