Dear José, I did a similar study with Bob Peters and Rob Milroy in 1983, but we used a simple randon melody task to ensure that the listeners were using pitch rather than a spectral position cue. You can do the task with 2-3 periods of a complex tone whereas it takes about 7 periods of the fundamental on its own. In the paper, we interpret this as meaning that the pitch is stronger for the complex tones. The reference is Patterson, R.D., Peters, R.W. and Milroy, R. (1983).
