Hi Stephanie and thanks for your comments. Usually DAF effects are measured when participants are reading. This is not always the case but, DAF effects on the conversational speech of normally-fluent people had not been measured prior to the Corey and Cuddapah (2008) article I mentioned. With respect to your questions on video recording, the answers are no, these participants were not video-recorded and yes, I think that having a visual record of DAF effects may be helpful in understanding sex differences in DAF effects. In my laboratory we no longer collect audio-only data (though no data including video measurement have yet been analyzed). I also want to mention that my data were obtained from normally-fluent people, not people who stutter. I mention this only because you referred to data collection sessions as "intervention sessions." This suggested to me a therapeutic treatment and I wanted to be sure that you understand that we were _not_ testing people with developmental stuttering. We have not yet measured sex differences in the therapeutic effects of DAF (but we will soon!). Thanks again for your questions Stephanie. Feel free to email me at dave@tulane or to reply to this message if you want to discuss more. Best, Dave
