Dear list members, I am in the process of redesigning a test dealing with attention and auditory saliency but then I have a doubt about how to define, and possibly control, the 'fixation point' (in the case of sound stimuli). I am using headphones, so head-tracking is not an option, I believe. I also have thought that, giving credit to a supramodal model of attention, I could provide a visual fixation point (a cross on the screen) but this would be a fallback solution since I would like to keep it unimodal at this stage (and I am addressing stimulus-driven attention). This may sound as a very naive question to most of you, but I am turning it to the community since I always got precious comments and feedback in the past.
