Dan From: AUDITORY - Research in Auditory Perception [mailto:AUDITORY@xxxxxxxx= ILL.CA] On Behalf Of Oberfeld-Twistel, Daniel Sent: 23 October 2014 10:16 To: AUDITORY@xxxxxxxx Subject: Got the de Boer & Kuyper paper; question about correlated stimulus= components Got it, thank you very much for you fast responses! A related question: the classical reverse correlation technique usually use= s the "white noise" idea and assumes that all stimulus components (e.g., ac= oustic energy in different spectral regions, or all the picture elements in an image) are *uncorrelated*. In contrast, in studies on "psychophysical re= verse correlation", we use multiple regression analyses which are not affec= ted by correlated cues/stimulus components (e.g., http://dx.doi.org/10.1371= /journal.pone.0050184). Is anyone aware of a technique for the "classical" reverse correlation as i= n the de Boer paper that can be used with correlated stimulus components?
