From: Sound localization in noisy contexts: performance, metacognitive evaluations and head movements
Spearman correlation between head-related behavior (mean number of reversals (A); mean extent of head rotation (B) and mean approaching index (C)) and performance (mean absolute error), irrespective of noise type. Each point showed average values calculated for each participant. Note that the approaching index refers to the values in centimeters of the minimum distance between the head position and the speaker emitting the sound reached during the trial. The starting distance at the beginning of the trial was about 55 cm, but participants were allowed to move naturally during the trial. Small values indicate that the participant came closer to the target
