Signal detection theory has been the dominant psychoacoustical paradigm since the 1960s. The contributions that our group has made to this field have primarily involved the role of fluctuations and modulation on detection, or the detection of these variations themselves.
The following references summarize our experimental and theoretical work in this area.
