Auditory motion tracking requires short time constants, but measured values vary by method

Evidence

It has been suggested that auditory motion processing relies on specialized circuits composed of directionally tuned and motion sensitive neurons in the midbrain (reviewed by Wagner et al. 1997 ). Time constants for processing of non-stationary dynamic cues must be short to allow tracking of moving sound sources (Wagner 1991 ). However, time constants for binaural processing have found to depend on measuring procedures (e.g., Shackleton and Palmer 2010 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 3182

• QUESTION: The dependence of binaural time constants on measuring procedures hints at a deeper methodological puzzle worth chasing: which measure reflects real tracking capacity?
