Implication

Psychophysical study demonstrates unified modeling of the precedence effect using adjustment and discrimination tasks, indicating consistent interaural delay weighting across binaural listening.

Key Points

To develop and evaluate a simple single-metric model that quantifies the dominance of leading over trailing interaural delays during sound lateralization.
Assessed lateralization using an adjustment task where listeners matched an acoustic pointer to composite binaural noise bursts varying in delay and overall sound level.
Measured interaural time difference discrimination thresholds for target noise bursts presented alongside preceding or trailing bursts.
Derived model parameters (dominance metric c and lateral position judgment variability) from the adjustment experiment to predict discrimination performance.
Model parameters calibrated from lateral position matching reliably predicted listener performance across conditions in the interaural time difference discrimination task.
Quantitative estimates of dominance metric c corresponded closely with values calculated from historical precedence effect literature.
