girl is raised in an ultra religious society where tickling is nearly non existent, and then she's tickled. Its so obvious that her reaction to it is influenced by her culture!
I for my part have never lived in an ultra religious society, and I couldn't make a statement about if it is true or not true that there is or isn't tickling in a - say strictly Muslim culture. I am pretty sure though that there is no comandment against laughing in the Quran or Sharia, so I don't believe that women tickle their children or female friends in a culture like that any more or less than in a less religious culture. That is the point I am trying to make. Tickling is harmless, tickling happens everywhere, tickling is not a taboo in other cultures like eating dog meat here!
But even if it was, I don't believe that the reaction of someone who never got tickled before would be different from someone who gets tickled regularly. The reaction is still laughter or scream. Same thing with pain. If someone feels pain for the first time, the reaction is the same all over the world.
