Beyond just interrupting or not, there are norms in conservational turn taking that vary between languages, cultures, and individuals, which are well studied by linguists. One example is the use of pauses. To me, in casual conversation, pausing for half a second cedes the floor, and pausing for two seconds means we're done with a topic. But I had a friend who would always pause for two seconds before saying anything at all. Neither of us interrupted, but there were still constant collisions.
