Subject:From: Clemens Maidhof <clemens.maidhof(at)WEB.DE> Date: Thu, 20 Nov 2003 01:47:54 +0100 Organization:http://freemail.web.de/ Dear List, we are planning a study to examine the effects of selective attention on the processing of speech and music (i.e., to what extend is music processed if the attention is focused on speech, and does music influence somehow the processing of speech). Speech and music will be presented via headphones simultaneously to the participants and attention should be directed to music in one condition and to speech in the other condition. A dichotic listening situation with speech presented to the one ear and music to the other ear would be (and sound) rather unnatural, but we couldn't find any study in the literature where the stimuli are mixed in one channel. So my question is: can I "mix" the two channels (so as if there is one person talking from the right side and a radio is playing simultaneously some music from the left side)? If yes, what would be an appropriate ratio of music/speech (20/80; 30/70, 50/50) in one channel ? Is the level of "gating" (cochlea(?), brain stem (?), thalamus (?), cortex) for both information (speech/music) different in a dichotic listening situation? At this level we are mainly interested in the effects of selective attention, and not in the specialization of the two hemispheres for music- and speech processing, so a dichotic situation is not necessarily needed. Looking forward to read your advises and remarks! Thank you very much and best regards, Clemens Maidhof ______________________________________________________________________________ Horoskop, Comics, VIPs, Wetter, Sport und Lotto im WEB.DE Screensaver1.2 Kostenlos downloaden: http://screensaver.web.de/?mc=021110
