Subject: User Studies - Voice tests under stress From: "Flaithri.Neff" <Flaithri.Neff@xxxxxxxx> Date: Mon, 30 Apr 2012 16:10:33 +0000 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>
Dear list, A number of colleagues and I have been conducting some preliminary studies looking at participants' vocal characteristics and speech-flow while under simulated stress conditions. However, while we are using various auditory distractors and concurrent tasks in an attempt to induce stress, it is clear to us that we are not activating genuine stress in participants. Participants' speech-flow is significantly affected, but their feedback and our EEG data clearly tell us that participants are not genuinely stressed by the simulated conditions, just merely distracted. Can members advice us on how to induce genuine stress conditions that would register but that would also comply with ethical standards for studies such as this? Thank you in advance, Flaithri.
