Unsigned elevation errors for trials in the main experiment’s monaural condition on which the true sound-source elevation was compatible with the lateral angle at which the participant indicated the sound source was located (monaural), unsigned elevation errors for trials in the main experiment’s lp/wb condition (lp/wb), and unsigned elevation errors that would have been measured for the relevant trials in the main experiment’s monaural condition had participants followed the strategy that will tend to minimize elevation error in the absence of information regarding sound-source elevation (strategy) for each of the five participants. Box plots show 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles.
