While neither of your sample groups are large, nor necessarily representative of the general population, there is, I believe, an important difference between them.
‘s sample comprised women who admitted they deserved the CP they received. By implication, they admitted they deserved to be punished, corporeally or otherwise.
Alan Turing‘s sample comprised three women, two of whom “resented having been caned”. The third woman’s opinion isn’t stated but I believe it’s safe to assume she didn’t resent it.
In the first case, she “was caned for being late to class” even though “the delay wasn’t her fault”. Personally, I would have resented even a mild telling-off in those circumstances.
