Multiple Factors and Multiple Mechanisms Determine the Quality of Conscious Experiences: A Reply to Anzulewicz and Wierzchoń.

In this Letter to the Editor, we seize the opportunity to respond to the recent comments by Anzulewicz and Wierzchoń, and further clarify and extend the scope of our original paper. We re-emphasize that conscious experiences come in degrees, and that there are several factors that determine this degree. Endorsing the suggestions of Anzulewicz and Wierzchoń, we discuss that besides low-level attentional mechanisms, high-level attentional and non-attentional mechanisms might also modulate the quality of conscious experiences.
