Something specific to your data and analysis techniques seems to be necessary for your effects to appear. I reported in detail conditions to which your results did not generalize, and also argued why they were expected to generalize to those conditions if the effect has any generality. My methods are certainly "insufficient" in that they failed to reproduce your nice results. I'd be glad to improve them, for example if you provide me a formal account of how speech targets should be assigned based on F0 contours (saying it's done by hand does not qualify). If you don't, I can only continue to be skeptical. >Once you have extracted the speech-target f0 values with similar precision >as the researchers at the IPO and then applied similar statistical >techniques as I did, FIRST THEN can you come out and say that my results >could not be replicated with your speech material. > >And please note, the question if my results generalize or not will not be >decided by ONE follow-up study, even if this is carried out in a technically >correct way.

In essence you are saying that your claims cannot be challenged unless with the same speech material and the same hand-marking technique (I presume employing the same hand-markers). This can of course be done if IPO lend the original data. Note however that this is a very restrictive rule for testing whether an effect generalizes. Especially one that is claimed to have implications as far-reaching as pitch perception and absolute pitch. Might those implications be true only for Dutch speech pronunced in the laboratory? TO THE LIST: We've been seeing a flurry of highly attractive propositions that often spark cascades of elaborations. Does it make no difference to anyone but myself whether any given proposition is actually true? If so I guess it'll soon be time to follow Ed Burn's footsteps. If not maybe it's time to raise the background level of skepticism a tiny wee bit...
