ABSTRACT
This chapter discusses models that have been applied to low-to-moderate-accuracy monaural tone detection. The most prominent is David Green's energy model and a model that he employed to test against the energy model, a model he termed the 'independent thresholds model'. The chapter distinguishes most accuracy-based from most response time (RT)-based models in psychophysics. Consequently, one of the fundamental research endeavors in psychoacoustics is elucidating the mechanisms that are responsible for combining information across frequencies to form these unified percepts. Townsend and Wenger discuss independence versus dependence in detail, and interactions between channels occur readily within the auditory system. Note that tones presented at high supra-threshold stimulus levels may be interacting within the auditory system at a peripheral level. RT tools have been used to evaluate the architecture of monaural auditory perception and the application of capacity measures.
